Insect repellents for the home - a review of the best products

Preparations for combating insects that maliciously damage agricultural crops and terrorize human homes have a rich history. Aristotle recommended an insecticide in the form of sulfur to kill lice. And pyrethrum was familiar to ancient warriors. Since then, more than one generation of chemists, zoologists and entomologists have been tirelessly working on toxic substances that reduce the number of insect pests and parasites.

In addition to plant poisons, chemical industry products are actively used - chlorine and phosphorus compounds, mineral oils, various types of emulsions (lime, soap, kerosene and others).

Insect repellents in the home in the form of aerosols

Broad-spectrum preparations are used against flying and crawling insects indoors. They are easy to use, do not contain an unpleasant odor, do not leave marks, and do not damage the material. Sold in spray cans. Before use, shake the can and remove the protective membrane.

Treat the floor, walls, ceiling. The bottle is held at arm's length at a distance of 20 cm from the surface to be treated. Leave the room closed for 2 hours, thoroughly ventilate, and carry out wet cleaning in areas where hands may touch.

On a note!

Insect repellents in the home in the form of aerosols contain several active ingredients and begin to act immediately after spraying the surfaces. The maximum effect lasts 2 hours, then the properties gradually weaken. After a week, the poison is completely neutralized. Insect repellents in the form of aerosols are most effective against flying and crawling pests if their habitat is known.

Repeated disinfestation is carried out after 7-14 days if necessary. While working, you need to use rubber gloves, a respirator or a gauze bandage. If safety rules are not followed, poisoning of varying degrees of intensity occurs.

Review of the best products

Given the wide range of modern insect control products, it is often extremely difficult to make a choice.

To make this process as easy as possible, below is a brief overview of the most effective options:

Aerosol Combat

Containing insecticides such as permethrin and tetramethrin, it is one of the most well-known and effective remedies for home use. It allows you to destroy all types of crawling insects and arthropods, while being able to poison even their eggs and larvae. Combat does not have a pungent chemical odor; instead, a pleasant floral aroma will remain on the treated surfaces. The cost of a can with a volume of 500 ml is about 400 rubles.

Aerosol "Raptor"

It costs less than Combat, but is no less effective. Available in 350 ml cans, the approximate cost is 250 rubles.

Get insecticidal soap

Effectively gets rid of ants, bedbugs and cockroaches. You can even treat carpets with it; the product can then be easily washed off and will not leave stains behind. The approximate price of such soap is 400-420 rubles.

Avalon product

It is an emulsion concentrate from a South Korean manufacturer. The main advantage is the versatility of the solution obtained from it, which destroys all crawling and flying insects and provides protection against them for several weeks. The cost of one 50 ml bottle is about 600 rubles.

Foresight tool

It is also an emulsion concentrate, the main active components of which are cypermethrin and fenthion. First of all, the drug is intended to kill ticks, but it also shows good effectiveness against other crawling insects. The price for it is 350-400 rubles.

Means "Xulat"

Made in Spain, it is intended for preparing a solution based on it. The composition includes various insecticides, which allows you to destroy even insects with developed immunity to certain components. A 30 ml bottle costs about 500 rubles.

When to treat plants

All drugs have instructions for use. in which the dosage is indicated in detail, as well as favorable conditions for spraying. The rules for processing garden crops are as follows:

  • It is worth considering the phase of the insect’s life cycle when choosing an insecticide - for adult insects it is too late to use ovits, which only affect eggs;
  • when treating with several drugs, it is worth considering their compatibility, because if used incorrectly, chemicals can cause irreparable harm to plants;
  • treatment is not carried out as a preventive measure - only when the first symptoms of damage are detected;
  • When plants are flowering, you should stop spraying - this may adversely affect the quality and quantity of the crop;
  • the end of spraying occurs 40-45 days before harvest, since pesticides can harm the human body.

To obtain maximum effect, treatment should be carried out in dry, windless weather, in the evening.

You should also avoid dripping of the drug from the leaves and strictly adhere to the instructions from the manufacturer.

Types of fleas and methods of getting rid of them

Such an unpleasant neighborhood is quite dangerous for health. Firstly, they suck blood from pets and people, which causes pain and itching, often causing severe itching and redness. Secondly, they can carry contagious diseases and infections, such as hepatitis, malaria or typhus. That is why, at the first sign of fleas in the house, it is necessary to immediately begin disinfection.

Most often, earthen, grass and fleas enter the house, which are localized in the animal’s fur; they can be found in the following places:

  • rugs and carpets;
  • linen drawers and cabinets;
  • soft corners, armchairs, bed;
  • grooves and slots;
  • in baseboards and window sills;
  • on pet bedding.

Insects on animals

If the animal constantly itches and behaves restlessly, this may indicate the presence of fleas. They are quite easy to see in their fur, so it is worth checking behind the ears and on the belly.

Such insects can also infest a person and bite him, so it is necessary to quickly destroy them, this can be done using various means, the most effective are considered to be:

  • special cleaning compounds;
  • drops for wool treatment;
  • a collar, but it is more often used as a preventive measure;
  • spray or aerosol.

Products in the form of sprays and aerosols act more quickly and effectively. But when using it, you need to take into account that pets lick their fur, so you should play it safe in advance and wear a special collar. In this case, there is no need to fear that the animal will be poisoned.

Bed and linen pests

As a rule, linen fleas constantly move because they need to eat, but they choose linen closets and mattresses to lay their eggs. These are the places that are more comfortable for them. If, after using clothes, characteristic bites appear on the skin, the limbs especially often suffer from this, and small black dots appear on the bed linen, then there is no doubt that there are blood-sucking gnats in the apartment.

There are several ways to get rid of this type of insect:

  • carry out a thorough wet cleaning of linen closets and drawers using acetic acid or laundry soap;
  • boil and then wash the clothes;
  • thorough ironing of items before use;
  • all bedding, such as a pillow, mattress and blankets, are taken out for several hours in the cold in winter or in the bright sun in summer.

All these methods help to combat indoor fleas quite effectively. At the same time, you should not limit yourself to one option; it is advisable to use the whole complex.

Grass and soil parasites

The herbal type of bedbugs enters the house exclusively in the warm season; most often it appears in a private house or in dwellings located on the ground floor. Active growth and reproduction of these parasites occurs in rooms where there is no good lighting and ventilation, and high humidity and dampness prevail.

Concentrates

Insect repellents for apartments and houses based on a broad-spectrum insecticide. They are highly effective, killing adults, nymphs of different ages, and larvae. The maximum effect lasts 2 hours, the residual effect is present from 14 days to 6 months. The most effective microencapsulated concentrates. The toxic substance is in a capsule that is not afraid of high temperatures and sunlight.

Insect poison is used to kill bed bugs, cockroaches, a large number of flies, and mosquitoes. Before disinsection, you need to prepare a solution - the concentrate is diluted in water at room temperature, stirred for 5 minutes, poured into a spray bottle or spray bottle. Spray walls, floors, ceilings, furniture from the back side.

Important!

When working with toxic substances, you must use rubber gloves, a protective suit, and a respirator. Contact of the poison on the skin causes an allergic reaction, and in the respiratory tract - intoxication of varying degrees of severity.

Effective pest control products:

  • Sinuzan;
  • Executioner;
  • Cucaracha;
  • Tetrix;
  • Delta Zone.

After treating the rooms, leave the room closed for 2 hours, then ventilate thoroughly. Carry out wet cleaning in places where hands will touch. Soapy water with the addition of baking soda completely neutralizes the effect of the poison. If necessary, repeated disinfestation is carried out after 14-20 days.

Professional insect control products

You can buy the drug in a specialized store. The price depends on the capacity. 10 ml of concentrate is enough for two treatments at home or in a large apartment. The cost of a bottle is from 300 rubles. up to 1000 rub. The shelf life of insect repellent is 2 years from the date of manufacture. The prepared solution should be used within 3 days, or better immediately after dissolving the poison in water.

  1. Alexander: “Without much success I fought cockroaches with various store-bought products, but I didn’t pay attention to them, since they don’t cause significant discomfort. I only sounded the alarm at the moment when bedbugs appeared in the house and bit my wife and me at night. I didn’t have time to figure out how to get rid of these parasites, so I decided to simply call specialists to remove them. We used the service of spraying cold fog in the apartment. My wife and I returned to the apartment 5 hours after treatment, removed all the smell and carried out a global cleaning. The bedbugs disappeared after the first procedure, and along with them the cockroaches disappeared, which was a good addition to the main service.”
  2. Anastasia: “I used gel against cockroaches, used it according to the instructions: dripped into the cracks and treated potentially dangerous areas. It was actually possible to remove these insects, but the cat was seriously poisoned and had to go to the veterinarian. This is despite the fact that many people talk about the safety of such products for pets. Only later did I learn about the existence of gels that contain special bitter ingredients that repel pets. I really regret that I didn’t know about this earlier and I advise other people to pay attention to the composition of the drugs they purchase.”
  3. Alla: “I always believed that removing cockroaches is a very difficult task that requires a lot of time and effort. I personally became convinced that this can be done very easily with the help of Raid aerosol, which in just a week helped get rid of the Prussians that were left to me as a gift from people who rented an apartment. I took the rest of the drug with me to the dacha, where I tried it on ants and spiders, and it also helped a lot against them.”

Preparations for open air

To prevent annoying mosquitoes, midges and ticks from bothering you in nature, manufacturers recommend using mosquito repellent bracelets. This is a very convenient and also effective way to protect yourself from flying and falling insects. This product is a small strip of special material about 1 cm wide, impregnated with a non-toxic solution. Bracelets do not cause an allergic reaction. Their service life is 1 month, so this universal product can be worn by both adults and children from 2 years of age.

The patch has a shorter duration of use. This small adhesive elastic strip sticks to clothing and remains active for 12 hours. This is a very convenient device for small children.

The next drug that repels and destroys harmful insects is an aerosol. Its single application to clothing or skin has a protective effect for 4 hours. It should be remembered that when spraying the body, the substance should not be applied to the palms, area around the eyes and mouth. When using the aerosol by children, it is advisable to treat only parts of clothing.

Manufacturers suggest using creams for the same purpose. It is recommended to apply them in a thin layer on the body, but avoid contact with open wounds or scratches. In addition to the protective properties of such substances, they also provide hydration. The maximum effect of the cream is achieved when used on damp skin. If such a substance is intended for children, then it should be chosen only with natural ingredients to avoid allergic reactions.

For similar purposes, you can use lotions with different scents. They are also applied to the skin, but rubbing such products is not recommended.

For children, you can use wet wipes with special impregnation against insects. They are easy to use and do not leave stains on clothes, and when applied to the skin they are quickly absorbed. When treating a child’s body, you should follow the standard rules and do not use wipes in the area of ​​the mouth, eyes and palms.

Fumigators

Simple, easy-to-use insect repellents with low toxicity. They are made in the form of plates, liquids, and spirals. Effective against flying insects. The active substances are contact insecticides. As well as substances that enter the body of pests through the respiratory tract.

  • Electrofumigators. House Insect Repellent runs on electricity. A plate impregnated with insecticides is inserted into a special device, or a bottle of liquid is screwed on. When heated, a toxic substance enters the air. This concentration is not noticeable to humans; pests die within 20 minutes. The device operates silently, plugs into a power outlet, and is enough for one room.
  • Spirals. Insect repellent on the street, in the veranda, on the terrace, in the gazebo, but is often used indoors. A significant drawback is the unpleasant smell. The spiral is made from pressed shavings impregnated with an insecticidal substance. Place it on a non-flammable surface and set it on fire. Acrid smoke is released that poisons insects. When using indoors, be sure to open a window or window. Otherwise, headache, dizziness, and nausea appear.
  • Aquafumigator. The only fumigator of its kind is Raptor. It works similar to the professional disinfestation method - drip spraying. It is more effective than concentrates, aerosols, powders, electrofumigators, and other insect repellents. The toxic substance is released along with droplets of moisture, penetrates into hard-to-reach places, and passes through the fabric surface. A special jar of poison is inserted into the water; upon contact with the liquid, a chemical reaction begins and the fumigator begins to burn. The action lasts 2 hours. The residual effect lasts for 2 weeks.

Fumigators for insect control Effective insect repellents:

  • Raptor;
  • Raid;
  • Clean house;
  • Quiet evening;
  • Mosquitol;
  • Gardex.

In the warm season, insect repellent products are sold everywhere. Many brands make several types of fumigators. Electrical devices based on plates and liquids are especially popular. The plates need to be changed every night; a bottle of liquid lasts for a month. During the day, the device must be turned off; in the evening, it must be turned on 20 minutes before bedtime.

On a note!

Separately, products are produced to protect children from insects based on the natural insecticide – pyrethrum. Obtained from Caucasian chamomile. It has a beneficial effect on the nervous system and smells like flowers. Install the device at a distance of at least 2 m from the sleeping place.

The cost of spirals is from 50 rubles, the price of an electric fumigator with plates or liquid is on average 450 rubles. They act against mosquitoes, flies, moths, and fleas.

Damages the nervous system

In the 20th century, people fought dangerous insects with varying degrees of success, inventing new and new chemicals that became more and more harmful to insects and less harmful to humans. Together with the Raptor brand N + 1

trying to figure out how different groups of insecticides differ from each other and how they work.

We'll poison you with whatever we have to.

Even in ancient China, it was noticed that dried flowers of some types of chamomile can be used as insecticides—plants that are poisonous to insects. Later, similar substances were used in Persia, and from the end of the 17th century they began to be studied in Europe, when insecticidal properties were discovered in Dalmatian chamomile flowers brought from the Caucasus (also known as tansy, Chrysanthemum cinerariifolium

, or
Tanacetum cinerariifolium
).

At the beginning of the 20th century, insecticides began to be isolated from other substances of natural origin, for example, from ground derris root (genus Derris

) or graceful ryania (
Ryania speciosa
). The first of these plants can be found in Southeast Asia, the second in South America. The indigenous people of these regions knew for a long time that they are poisonous to some animals and used their poison, for example, when fishing. But they began to be purposefully used to combat harmful insects only at the beginning of the 20th century.

However, the first chemical compounds used to destroy entire colonies of insects in homes and agricultural plantations were not substances of natural origin, but well-known inorganic poisons. Thus, in the second half of the 19th century, salts containing arsenic began to be used to protect against the Colorado potato beetle. The most popular of them were lead and calcium arsenates, as well as sodium arsenite and copper acetoarsenate.

In living organisms, arsenic-containing salts replace phosphates in phosphorylation reactions, resulting in the formation of unstable esters of arsenic acid. In turn, trivalent arsenic in arsenites reacts well with thiol groups in tissue proteins and enzymes and thus inhibits them, which is why the nervous or cardiovascular systems of the insect stop working.

The same processes, however, occur in a large number of different tissues of many animals, so arsenic-based poisons are not very selective and are very dangerous for humans. They were quickly abandoned, and the search began for substances that, on the one hand, were more effective, and on the other, deadly only for those insects that one wanted to get rid of, but relatively harmless to humans and other animals.

Therefore, substances that have more specific effects are now used as insecticides - they interfere with the normal transmission of nerve impulses, complicate cellular respiration, or prevent the body from developing normally.

We deactivate cholinesterase

Effective insecticides include, in particular, substances that prevent the insect’s nervous system from functioning normally. In invertebrate arthropods, the nervous system is much simpler than in humans, but its activities are based on the same basic processes. In the reflex arcs of insects there are three types of neurons: sensory, associative and motor. They, accordingly, receive signals from sensitive receptors, process the received information and transmit it to the effector organs.

The process of signal transmission through nerve cells includes two main stages. After the initial excitation, the impulse spreads along the processes - axons - of one cell, changing its membrane potential as a wave due to the work of ion channels. When this wave of membrane recharging reaches the end of the axon, a completely biochemical stage is launched - signal transmission from one cell to another using neurotransmitters. Therefore, in order to block the normal functioning of the insect’s nervous system, it is necessary either to spoil the work of the mediators, or to prevent the impulse from spreading along the axon of the nerve cell.

Substances suitable for the first of these methods began to be actively studied in the 30s of the 20th century, simultaneously with the development of organophosphorus toxic substances for humans. The principle of their action is the same as that of military poisons - they prevent acetylcholine, the main neurotransmitter of insects, from working normally.

This mediator works like this: as soon as a nerve impulse travels along the axon of an excited cell to a synapse—the junction of two nerve cells—a certain amount of acetylcholine is released into the gap between them. To transmit a signal, it binds to receptors on the membrane of the second cell, triggering an electrical wave on its membrane, after which the transmitter molecule is “turned off” due to hydrolysis using a special enzyme - acetylcholinesterase. This switch-off allows the acetylcholine receptors on the membrane not to become clogged and returns them to their initial state, preparing the synapse to receive the next impulse. You can read more about the mechanism of acetylcholine’s work in our material “Novichok” and that’s all.”

To combat different types of insects, fumigators of different formats are used: aquafumigators - against all types of insects, primarily against crawling ones; heat fumigators - against moths and mosquitoes; electrofumigators - against mosquitoes. In all fumigators, as a result of heating, active substances are released. “Raptor” has fumigators from Zobele companies in its arsenal and uses liquids based on the active substance Etoc, produced by the Japanese corporation Samutomo.

There are several ways to break this pattern. You can block the work of acetylcholinesterase itself. This will result in the spent acetylcholine not being hydrolyzed and remaining bound at the acetylcholine receptor. The enzyme can be forced to stop working normally using suitable inhibitors - organophosphorus compounds and carbamates. These substances respectively phosphorylate or carbamoylate the esterase center of the enzyme and thus prevent it from breaking down acetylcholine into choline and acetate. These inhibitors now constitute one of the most used classes of insecticides.

Phosphorylating insecticides primarily include esters of phosphoric, thiophosphoric and phosphonic acids. The best known of these compounds in use today is undoubtedly dichlorvos - O,O-dimethyl-O-2,2-dichlorovinylphosphate. Other related substances are also widely used, such as thiophos (O,O-diethyl-O-4-nitrophenylthiophosphate) or methyl parathion (O,O-dimethyl-O-4-nitrophenylthiophosphate).

Interestingly, some of these substances were discovered much earlier than they began to be used as pesticides. For example, tetraethyl pyrophosphate was first synthesized back in the 50s of the 19th century, but for almost 80 years its toxic effect (for both insects and humans) was not known.

Despite the fact that modern organophosphate insecticides have become much safer for humans than in the early stages of their research, they account for 80 percent of cases of organophosphorus poisoning. About 250 thousand people a year die due to their careless use.

Other common pesticides, carbamates, work by the same mechanism—by blocking acetylcholinesterase. When cholinesterase reacts with carbamates, instead of a phosphoric acid residue, a -CONH2 group is added to its active center. This leads to the same effect, but sometimes works in cases where organophosphorus is not applicable due to the biochemistry of a particular insect species. Carbamates are used much less frequently than organophosphates, and the most important of these compounds is carbaryl (1-naphthylmethylcarbamate), which is lethal to, for example, beetles, flies and bedbugs.

Some modern insecticides also affect other neurotransmitters. For example, one of the now popular insecticides, fipronil, blocks the inhibitory neurotransmitter - gamma-aminobutyric acid. As a result, the insect (fipronil, for example, is used in gels against cockroaches) experiences overexcitation of the nervous system, and after a few hours it dies from paralysis.

Blocking receptors

Another way to disrupt nerve signal transmission across a synapse is to directly block the postsynaptic receptors. If the receptor intended for acetylcholine is occupied by another substance, then the neurotransmitter will have nowhere to attach and the nerve impulse transmission system will stop working. This can be done using another type of pesticide - nicotine and its analogues. These compounds are integrated into nicotinic acetylcholine receptors, and since the majority of such receptors are on the dendrites of insect cells, the nervous system is blocked and the insect dies.

Initially, both pure nicotine and its sulfate, as well as tobacco dust, were used as insecticides. Now, instead of them, neonicotinoids are more often used - synthetic analogues of nicotine with the same functions. A typical example of a modern neonicotinoid insecticide is, for example, imidacloprid, which is used mainly to control agricultural pests, in particular against aphids, whiteflies or the Colorado potato beetle.

Aerosols, traps and gel are commonly used to control crawling insects. Raptor traps contain fipronil and emamectin benzoate, compounds whose primary target is the nervous system of insects. Raptor gels also contain the latest generation active ingredient lambda-cyhalothrin, which works in a similar way.

Share

Recently it turned out, by the way, that if insects receive neonicotinoids in food in small concentrations, then they, just like people, may become dependent on these dangerous insecticides.

Gamma-aminobutyric acid receptors can be blocked in the same way. This is how another innovative insecticide, emamectin benzoate, works. At the same time, it additionally binds histamine receptors in muscle cells, due to which the muscles relax and the insect dies within several tens of hours.

We inhibit the transmission of impulses along axons

It is possible to block the activity of the nervous system of insects in another way - by influencing the signal transmission process not at the stage of neurotransmitters in synapses, but when a recharge wave propagates along the membrane of the nerve cell. This can be done by disrupting the sodium-potassium channels of the axon through which the signal should propagate. Then its membrane loses its ability to maintain the required ratio of ions on both sides of itself and the entire system stops working.

This is precisely the principle of action of the most famous insecticide of the 20th century - DDT (aka 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane). It is an organochlorine insecticide that opens sodium channels on the axon membrane. Because of this, the necessary balance of potassium and sodium ions on both sides of the membrane is disrupted and the jump in membrane potential cannot spread along the cell, which ultimately leads to paralysis of the insect.

In the mid-20th century, it was DDT that helped protect crops of grains, corn and many vegetables, and also prevented several typhus epidemics and sharply reduced mortality from malaria. Swiss chemist Paul Müller received the Nobel Prize in Medicine for his discovery of the insecticidal properties of DDT.

At the same time, DDT is safe for humans and warm-blooded animals in the concentrations needed to combat harmful insects. However, it turned out that it can accumulate in the fatty tissues of humans and animals and is extremely resistant to biodegradation in the environment. One recent study showed that high levels of accumulated DDT in a pregnant woman's body can lead, for example, to autism spectrum disorders in her child. Since the 1970s, the use of DDT has been banned in most countries.

For the same reasons, other compounds from the class of organochlorine insecticides are now used relatively rarely and are significantly inferior in prevalence to the same organophosphates.

Pyrethrins work in a similar way - the same compounds that were obtained from certain types of chamomile back in Ancient China. In the case of pyrethrins, several substances take part in the process of blocking ion channels, which, due to their joint sequential work, cause “knockdown” of the insect and almost instantaneous death.

Pyrethrins are esters with a cyclopropane ring, the biological action of which is determined by the so-called pharmacophore fragment. Nowadays, natural pyrethrins are practically not used, but pyrethroids are used - synthetic compounds with a similar mechanism of action, which are significantly superior to natural substances in both efficiency and stability.

Examples of modern pyrethroids are, in particular, imiprotrin or bifetrin, which also contain an ester group. To increase their effectiveness, piperonyl butoxide is also often added to insect repellents, which enhances the effect of pyrethroids due to a synergistic effect.

We inhibit intracellular processes

Some insecticides act more roughly - they do not interfere with the relatively delicate work of nerve cells, but “break” the biochemical processes inside all cells with which they come into contact. This is exactly how nitrophenols, arsenates and rotenone work - first-generation synthetic insecticides from the 19th century and natural substances.

As a rule, these poisons work by inhibiting intracellular oxidative processes. For example, rotenone, which is obtained from the already mentioned derris root, is known as a specific inhibitor of tissue respiration. It blocks the transfer of electrons along the respiratory chain in mitochondria from the iron-containing cluster in complex I to ubiquinone in complex III. This leads to the accumulation of excess NADH, a dinucleotide that acts as an electron carrier within the cell, in the mitochondrial matrix. And because of this, oxygen appears in the form of radicals, which damages DNA and ultimately leads to the death of the insect.

We do not allow the insect to develop

To combat insects, in addition to the chemical attacks described above, there are more sophisticated methods. A whole class of insecticides, the most common of which are diflubenzuron and lufinerone, are not at all dangerous not only for humans and warm-blooded animals, but even for the insects themselves. But only if these insects are old enough. Such substances are called larvicides; they are specifically intended for insect larvae and prevent them from developing normally.

These compounds act by interfering with the normal functioning of ecdysone, a hormone that regulates the synthesis of chitin, the main component of the insect exoskeleton. During the process of growth, the larva has to molt and renew its exoskeleton several times, and if, during the next change of the chitinous shell, it is not possible to grow a new version of the cuticle, the larva becomes defenseless and dies.

An adult animal no longer needs to change its cover, so such substances do not affect it. These compounds can be used both directly to combat harmful caterpillars and to prevent insects from growing into pests or carriers of dangerous diseases. It is these insecticides that serve as one of the most effective means, for example, in the fight against cockroaches. In addition to cockroaches, such compounds can be used against mosquitoes, fleas or whiteflies.

Let us note once again that almost all mechanisms of action of insecticides (with the possible exception of blocking chitin synthesis) are also dangerous for humans, albeit in much higher concentrations. And despite the constant decrease in toxicity to humans, these substances are still capable of causing harm. Due to careless handling of poisons, several million people a year are poisoned by one or another insecticide. Therefore, do not forget about safety measures when fighting insects.

What are weeds and what weeds are related to it?

Weeds (or weeds) usually mean plants that have grown where other crops were originally planned to be grown. As a rule, the appearance of such weeds reduces the yield, or, if it is a flower garden, worsens its decorative properties.

Weeds can be divided into annual and perennial:

of weeds, many of which are not so bad at all, and even medicinal .

But the most “troubling” weeds in our gardens are creeping wheatgrass, which is also called “dog grass” (although the roots of this plant are very useful and have an enveloping, diuretic, hemostatic, expectorant and diaphoretic effect), as well as Sosnovsky’s hogweed , which can grow simply to unimaginable sizes and if you come into contact with it, you can get quite a severe burn, even through your clothes.

Video: how to defeat hogweed

Dusts act by contact-intestinal route. They penetrate the body and cause muscle paralysis and death. In order for the poison to get inside, you must first run over it, get dirty, and then lick it off. For this reason, powders, dusts, and crayons are rarely used as an independent means of control; they are combined with aerosols and fumigators. Used against crawling insects: cockroaches, fleas, ants.

Effective means:

  • Clean house;
  • Chalk Mashenka;
  • Super Fas;
  • Storm;
  • Frontline.

You can buy the drug in a specialized store, hardware departments of supermarkets, retail outlets on the market, or you can order via the Internet. Shelf life: up to 4 years; store away from direct sunlight in a dry place. Price per package from 10 rub.

What types of “domestic” insects are there?

Representatives of about 15 species of arthropods take root in the apartments.

Mukoed Suriname

The cereal beetle loves bulk food and breeds in them. The insect is difficult to detect because its body length is only 3.5 or 4 mm. The Suriname mucoede excretes excrement into the cereal, and the product begins to rot.

After eating porridge made from buckwheat with bugs, a person suffers from an upset stomach; the husk causes allergies. The insect lives up to 3 years, during which time the female lays about 5 hundred eggs 1 mm in size. The flour beetle reproduces well at room temperature in the dark; it usually gets into the house from the store along with a bag of cereal.

Flour beetle

The insect easily crawls into cracks, where it hides eggs, from which larvae emerge. In houses and apartments, the black beetle prefers to live in the pantry or settle in drawers in the kitchen. Khrushchak insects penetrate along with bulk products and love raw cereals and wet flour.

Grinder

Miniature beetles cause enormous harm, destroying plywood and cardboard, damaging wooden furniture and walls, and gutting books. The larvae of some types of borer do not disdain:

  • medicines and tobacco;
  • plaster and glue;
  • bakery products;
  • cereals and flour.

On the chest of the insect there is a shield, when struck by it the beetle gnaws its way, making a sound reminiscent of the ticking of either a clock or an explosive device.

food moth

A butterfly less than a centimeter in size often settles in the kitchen, where it breeds offspring, burrowing into nuts, dried fruits, and cereals. For insect reproduction, high humidity and regular ventilation of the room are sufficient. In flour, millet, buckwheat, noodles, food moths leave feces and dead larvae, and it is easy to get poisoned with such products.

Red mukoed

A small beetle with an oblong shape, it is most often found in mills, granaries, and bakeries. The insect's body is covered with villi, its hard wings are colored red. The bug breeds in high humidity and prefers to multiply in raw flour and rotten feed.

Rice weevil

An insect with bright spots on its wings, native to South Asia, quickly spread across all continents, with especially many bugs in regions with hot climates. The rice weevil feeds on cereals and does not refuse buckwheat and millet. The female insect lays eggs inside the grain, for which she gnaws holes. The beetle larvae eat all the substances, after a month they gain weight and become pupae.

Classification

Based on the type of active substance, insecticides are divided into the following groups:

  1. Pyrethroids (“Tsunami”, “Senpai”, “Decis”, “Intra-vir” and others).
  2. Based on imidacloprid (“Biotlin”, “Confidor Extra”, “Iskra Zelenaya” and others).
  3. Phenylpyrazoles (“Cosmos”, “Regent”, “Axial”, “Standac Top” and others).
  4. Based on malathion (Karbofos, Iskra-M, Antiklesch, Actellik and others).
  5. Based on avermetins (“Agravertin”, “Fitoverm”, “Vermitek” and others).
  6. Neonicotinoids (“Neoron”, “Aktara”, etc.).

As reviews show, insecticides based on organophosphorus compounds are practically a thing of the past. Research by scientists has shown that such chemicals have a negative effect not only on pests and parasites, but also on humans, being carcinogens. In addition, many compounds from this group caused resistance (immunity) in plants, which negated the advisability of their use.

According to their action, insecticides are divided into:

  1. Continuous action drugs. Several types of pests are affected simultaneously.
  2. Selective agents. They only affect a certain type of insect.

Depending on the method of entry of the substance into the insect’s body and the mechanism of its action, insecticides are divided into four groups:

  1. System.
  2. Intestinal.
  3. Contact.
  4. Fumigants.

We will consider each type separately.

Main groups of insecticides

According to the mechanism of action, insecticides are divided into four groups:

  1. Contact insecticides kill insects only in direct contact with the pest. That is, if you used such a drug near a wasp nest located in the attic, then you do not have to worry that the hive with bees will suffer.
  2. Intestinal insecticides enter the insect's body along with food and poison it. As a rule, such drugs are used to combat gnawing insects.
  3. Systemic insecticides penetrate into the roots and green mass of plants, destroying the insects living there. They usually contain substances with a high degree of toxicity.
  4. Fumigants are in gaseous form and act through the respiratory organs of pests, thus effectively controlling them.

In addition to chemical ones, today on store shelves you can find many biological insecticides , the active ingredients of which are fungal spores, strains of microorganisms, etc.

These drugs include Lepidotsid and Baktofit, created on the basis of the bacteria Bacillus thuringiensis and successfully used against caterpillars, as well as Bitoxibacillin, an insecticide for potatoes, which is sprayed on plants against the Colorado potato beetle. The main advantage of biological preparations is their rapid decomposition, due to which the crop remains harmless to your health.

  • What insecticides will help exterminate insects without harming humans? Is it possible to cope with insect pests without “chemistry”? Quite, because nature has long taken care of ways to protect against various misfortunes. Some insecticides affect all insects without exception. But there are also selective drugs that affect only certain types of pests, without affecting harmless pollinating insects.

Among them are:

  • Acaricides – preparations for killing ticks;
  • Insectoacaricides are products that kill a number of insects and mites, the destruction of which requires a special approach and active substances;
  • Aphicides are insecticides exclusively against aphids;
  • Larvicides are a group of insecticides that kill larvae and caterpillars of pests;
  • Ovicides are agents that act on the eggs of insects and mites.

Poisonous baits

Effective remedies against crawling insects - cockroaches, ants. The special gel consistency does not dry out for a long time when in contact with oxygen, and remains effective for up to 30 days. They update their defense as they eat “treats”.

The bait contains broad-spectrum insecticidal substances. If ingested, they block the transmission of nerve impulses, causing paralysis and death. Mass death of the pest colony is observed within a week. In addition to the active substance, the composition includes flavorings and flavoring additives. Insects eat poison better than regular food.

The gel is easily removed from the surface and leaves no traces. Apply with a dotted line to the baseboards, the floor around the perimeter of the rooms, and leave behind the furniture. The product is safe for humans and pets, but it is not advisable to use it in a home with small children.

The best gel baits:

  • Fas;
  • A great warrior;
  • Ant-eater;
  • Antiant;
  • Absolute;
  • Trap;
  • Battalion commander

You can buy the product in a specialized store, supermarket, market, and often order it online. Sold in syringes with a convenient dispenser. The price of one is from 50 rubles. The product should be stored in a dry place, away from direct sunlight.

On a note!

Moth baits are made in the form of tablets and sachets. They are laid out in cabinets, on shelves, in places where cereals and grains are stored. One tablet of protection lasts for six months.

An effective method of struggle

Pathogenic microorganisms settle in cereals, dried fruits, and flour damaged by bugs, but not everyone knows whether it is possible to avoid the appearance of insects in food products and how to deal with them.

Inventory inspection

If there are cereals, spices, tea in the kitchen or pantry, or beans, beans, dried apples, plums or pears are stored, the first thing to do is to carefully inspect the bulk products. The presence of insects is indicated by the appearance of husks.

Damage assessment

Having found traces of beetles, you need to check how damaged the cereals or dried fruits are. The flour can be sifted to get rid of the larvae if there are only a few of them. It is better to destroy products that are heavily chewed by insects.

Safe processing methods

To remove bugs and larvae, you must first try a method that does not harm humans.

Freezing

Most insects that live in bulk products die at low temperatures. Having identified traces of pests in a bag of cereal, it is left in the freezer for several days.

Roasting in the oven and sifting through a sieve

If the number of beetles and larvae in semolina, flour, and millet is small, it is worth trying to save the products. Insects cannot tolerate not only low but also high temperatures. The cereal and ground grain are passed through a fine sieve and then put into the oven, heated to 50 °C.

Disposal

Products found that cannot be fried or frozen due to severe damage by insects must be immediately taken to the trash pit along with their containers; the compounds used to treat the cabinets must be poured into the toilet.

Disinfection

To finally remove bugs from the kitchen or pantry, all shelves are cleared of food, crumbs are swept out and disinfected with a solution prepared from a liter of water and 20 ml of vinegar. The cracks in which insects lay eggs are poured with boiling water or removed with a vacuum cleaner.

Making bait from borax

You can attract bugs in order to deal with them later using balls, which are placed in cabinets that have been washed and disinfected in advance. To prepare them you will need only 3 components:

  • ground millet;
  • powdered sugar;
  • borax.

All ingredients are mixed in equal parts. In addition to the balls, pieces of paper with a ground mixture of baker's dry yeast, sugar and borax are laid out on the shelves. Very quickly bugs will appear near them.

How to deal with odor

Products and herbs that have a rich aroma are effective in combating food moths, red flour beetles and other kitchen insects.

Pyrethrum sprigs

The powder of the plant, found in Transcaucasia and the Balkans, has been popularly used for a very long time to kill bedbugs and harmful insects. The medicine is made from pyrethrum. The twigs of the perennial have a pungent odor that food bugs do not like.

Bay leaf

The spice, which is always present in the kitchen, gives a bright aroma to any dish, drives away insects that adore flour and lay eggs in dried fruits. Bay leaves are scattered in the corners of the disinfected shelf; the bugs do not like the smell of the seasoning.

Dried wormwood

The bitter herb, which has healing properties, grows near houses and gardens like a weed. It is harvested and dried to remove worms and improve appetite. Insects are not able to withstand the smell of wormwood, and bugs will definitely not crawl into the place where the leaves lie.

Carnation buds

Cotton pads lubricated with essential oils are placed in the cabinet, disinfected after identifying food moths:

  • geraniums;
  • fir;
  • rosemary.

The aroma emanating from clove buds repels bugs. Insects do not tolerate the smell of basil.

Peeled garlic cloves

Bugs rarely appear in buckwheat, millet, or rice if a bay leaf or cloves separated from a head of garlic are placed in the container or jar where they are stored.

Lavender

The plant, which has a unique aroma and delicate purple flowers, is used as a seasoning, brewed as tea, and added to alcohol tincture. People really like the smell; insects hate it. You can place a bouquet of lavender flowers and leaves or a swab lubricated with essential oil in the closet. The aroma will drive away bugs.

To destroy eggs, larvae, and adult insects, shelves, cabinets, and glass or plastic containers are disinfected if cereals, flour, beans or dried fruits are stored in them. In addition to wiping surfaces with vinegar, you need to treat the container and room with boiling water and steam.

Insecticide treatment methods

There are several effective methods of treating with chemicals that are widely used in gardening. These include the following:

  1. Spraying the entire surface of the plant with an aqueous solution of the drug. In this case, special equipment is used - a spray bottle with a long hose in order to reach the upper branches. It is the most common and effective way to kill insects. Systemic insecticides for fruit trees are used mainly by spraying the drug.
  2. Pollination with a substance in the form of powder, with this method the concentration of the drug is higher, which guarantees its effectiveness.
  3. Burying granules into the soil allows you to fight parasite larvae that develop in the soil.
  4. Fumigation is the spraying of chemicals over garden crops in the form of steam.
  5. Soaking seeds in an aqueous solution of insecticide helps get rid of microscopic insect eggs.

The method is selected individually and depends on the wishes and capabilities of the gardener.

Recommendations

Prevention methods against insects are not as effective, but will still help reduce the risk of uninvited guests at home and in the garden.

These include:

  • Maintaining a sanitary level of hygiene in your home, timely disposal of garbage and household waste.
  • Destruction of individuals upon detection. Their numbers are growing exponentially, so action must be taken immediately.
  • In summer, use adhesive tapes, traps and ultrasonic devices to repel insects. It is better to use mosquito nets on the windows, and equip the doorway with curtains.
  • In the garden, prevent the growth of weeds, thin out the plantings in a timely manner, destroying identified pests.
  • Periodically dig up the soil, plant green manure plants that repel pests, and treat with insecticides in case of severe infestation.

Even in urban environments, it is impossible to completely protect yourself from contact with insects. They penetrate our homes, spoil the harvest and become a real threat to safety, spreading diseases. You can get rid of pests in different ways, taking into account the type of insects and the degree of infestation.

Folk remedies for insects

If there is no possibility or desire to use professional preparations, you can exterminate or drive away insects using folk remedies.

Folk remedies against insects

  • Boric acid. Colorless powder is scattered around toilets, sinks, in the toilet, on window sills, under baseboards when fighting fleas, cockroaches, and ants. To increase efficiency, boric acid is mixed with products. One of the most effective remedies is boiled potatoes, egg yolk, and water. Add poison to cookies, flour, sugar.
  • Lavender. A fresh, dry plant or essential oil will help get rid of a moth infestation. Bouquets are laid out on cabinets, hung, placed in the corners of rooms. Soak cotton wool or gauze with essential oil, leave it on the lid, and also add it to water for wiping furniture and floors. The smell of lavender effectively repels midges and mosquitoes.
  • Geranium. A universal repellent against many pests - moths, ants, mosquitoes, flies, bedbugs. A flower pot is placed in the kitchen, preferably on a windowsill. Enjoy a beautiful plant, a quiet life without insects.
  • Soda and salt. Folk remedy for fleas in an apartment or house. Mix in equal proportions, scatter on the carpet, floor, and leave overnight. The next day they vacuum, wash the floors, and remove dead insects.
  • Ammonia. Used to combat cockroaches, fleas, flies, mosquitoes, bedbugs. Pour the insect repellent into a container, leave it behind the furniture, on the windowsill, or soak a cotton swab. Add ammonia to the water for washing floors in the ratio of 10 ml of product per 10 liters of liquid. Wet cleaning needs to be done daily. Vinegar works the same way. Use in pure form or prepare a solution.

Essential oils of mint, lemon balm, limonella, chamomile, basil, rosemary will prevent mosquitoes from entering the room. Soak the cotton wool and leave it on the windowsill.

Insect pests and areas of their negative impact

Nature has decreed that in our lives we encounter representatives of the Insecta class literally at every step.
Moreover, if some of the species are neutral and even useful, such as bees, then many others give us quite a lot of trouble. When choosing a suitable insect repellent, you should clearly determine what kind of harm they cause and where the drug will be used. So, for example, if we are talking about mosquitoes, then in one case you will need a product that is applied to the skin, and in the other - a drug that is sprayed indoors. The main areas of harm that insects can cause to humans are the following:

  • direct danger to health, expressed in the spread of infection or bites;
  • damage to pets, garden crops and/or indoor plants;
  • spoilage of food products by eating them and destruction of building structures (especially wooden ones);
  • common discomfort caused by the unwanted presence of insects in apartments and houses.

If the last point has caused you confusion, we will give a common example. A cockroach, which is actually a harmless insect, getting into a plate of food will make most of us refuse to eat the contents of this dish.

Thus, the presence of insect repellents in the house or when traveling outdoors is a prerequisite for a normal and safe existence.

Preparation of the solution

For the success of the procedure, it is important to properly prepare the working solution. Typically, to do this you need to perform the following manipulations:

  1. Pour 1/3 of the water into the bucket.
  2. Pour in the emulsion or add the drug powder.
  3. Mix the mixture thoroughly for 5 minutes.
  4. Add remaining liquid.

The working solution must be used immediately or after the time specified in the instructions for use of the insecticide. It is important to note that when working with chemicals, regardless of their hazard class, you must adhere to safety regulations.

BC

The soldiers of Alexander the Great used powders of some types of mountain chamomile (pyrethrum) to destroy parasites.

Middle Ages

19th century

Dolmat chamomile

Dolmatian chamomile flower, used since ancient times as an insecticide.

In 1896, kerosene-soap and kerosene-lime emulsions were proposed to combat sucking pests, and in 1905, an emulsion of petroleum mineral oils. Herbal preparations were also widely used: anabasine sulfate and nicotine sulfate. [7]

XX century

At the same time, the group of chlorine-containing compounds to which DDT belonged was actively studied. In 1942, it was replenished with a drug effective in destroying pests - hexachlorocyclohexane (HCH) and its gamma isomer - landane (HCH was first synthesized by Faraday in 1825). Over the 40-year period, starting in 1947, when factories for the production of organochlorine preparations were actively operating, 3,628,720 tons of them were produced with a chlorine content of 50-73%. [6]

The list of insecticides approved for use in agricultural and private household plots in the Russian Federation is in the section Agricultural insecticides and acaricides.

The list of insecticides approved for use for medical disinfestation on the territory of the Russian Federation is in the section Insecticides and medical acaricides.

During World War II, organophosphorus compounds with insecticidal activity were first developed in Germany, and in 1949 the first pyrethroid was synthesized. [7]

The synthesis of pyrethroids began in the late 40s of the last century. Allethrin was synthesized in 1949, tetramethrin in 1945, and resmethrin two years later. On the world market of pesticides in the early 70s, they had a serious drawback: they relatively quickly lost activity in environmental conditions. [5]

Modern range of insecticides

The search is also underway for formulations that are convenient for storage, use and less dangerous for personnel. More effective methods of using insecticides are being developed. The main vector of recent decades has been the development and introduction of effective and less environmentally hazardous drugs. [6]

Currently, the Pesticides.ru website contains information about the following classes of pesticides:

How to prepare a working solution of insecticides - basic principles

It is necessary to dilute insect repellent preparations with water to a working condition while wearing protective clothing, goggles, a respirator, and always in strict accordance with the instructions. However, the preparation of most working solutions of insecticides requires compliance with several important conditions:

  1. using the right water;
  2. carrying out processing at optimal air temperature;
  3. preparing the working solution in accordance with the instructions.

What should the water be like?

Water with neutral acidity (pH 7) or slightly acidic (pH 5.5) is best suited for preparing an insecticide solution. At a pH above 7, a number of drugs lose their properties. Some gardeners use citric acid (3-5 g per 10 liters of water) or a 9% solution of acetic acid (5 ml per 10 liters of water) to acidify water.

The optimal water temperature for preparing the solution is 10-16°C. Often gardeners use water from wells, artesian wells or open reservoirs. In this case, it is better to prepare it in advance so that the water, after standing, reaches the required temperature. In cold water, drugs dissolve less well, and, as a result, the effectiveness of treatments decreases. It is not recommended to heat the water before preparing the solution, since in this case it loses some of the oxygen.

Optimal air temperature

When treating plants or soil with insecticides, be sure to take into account weather conditions and observe the temperature conditions indicated on the packaging.

The optimal air temperature for treating plants with insecticides is 12-22°C. At lower or, conversely, higher temperatures, the processing efficiency is significantly reduced. However, some insecticides of the pyrethroid class can be used even when the air warms up to 7°C. In any case, you should always carefully read and observe the temperature conditions indicated on the drug packaging.

Preparation of insecticide solution

Step 1. Take a suitable container and pour 1/3 of the required volume of water into it.

Step 2. Add emulsion, powder or water-soluble granules, mix thoroughly until the drug is completely dissolved (usually this takes about 5 minutes).

Step 3. Add the remaining water and stir again.

The prepared working solution cannot be stored. Use it immediately after preparation or within the time specified in the instructions for the drug.

If you are using a liquid product, shake it thoroughly before use to eliminate separation of the composition and dissolve any precipitate that has formed.

"Aktara"

The Swiss drug is available in the form of water-soluble granules or concentrated suspensions. Suitable for treating open ground crops, greenhouse plants and indoor flowers. Kills most parasites and pests that plague gardeners and flower growers. The drug is presented on the market in different packaging: from 1.4 gram sachets (enough to treat plants in a small greenhouse) to 250 gram packaging (enough for an entire farm). The insecticide is systemic and is produced on the basis of thiamethoxin. Absorbed into the leaves and root system, it acts regardless of weather conditions. Small volumes of the drug cost up to $3, and for the largest package (250 g) you will have to pay about $60.

Diatomaceous earth (diatomaceous earth)

Diatomaceous earth, or rock flour, is a sedimentary rock and consists of natural diatomites (shells of marine diatoms), silicon, and various minerals (calcium, boron, titanium, manganese, copper, iron, etc.). If the soap solution is intended for pests flying and crawling on plants, then dolomite is used to destroy ants , larvae of carrot and cabbage flies , cutworms and moths . Just sprinkle a little powder at the base of the plants, and pests will avoid the unfriendly substance. The only drawback of diatomaceous earth is that it dries quickly, so it must be applied whenever it rains.

Mountain flour is resistant to aggressive environments, acids and alkalis

Survival of rats is a sharp mind and incredible caution

Rats and mice have a sharp mind that helps keep them alive. There is another feature of the animals presented - division into categories and purpose in the group. There are test rats - they try to try food, assess the situation in relation to this or that “breakfast”. If no consequences occur after eating, then soon everyone will dine here.

Important! If something goes wrong, that is, the animal dies, the poisoned bait will no longer attract attention, and they will refuse the treat.

Almost all modern poisons that are used to poison pests are single-use. But it should be understood that rodenticides do not act immediately - death for the animal usually occurs only 5 days after eating a portion of food. Rats cannot warn their own brothers, since the effect of the poison does not bring any unpleasant sensations, and the rodents still have an excellent appetite. But there is also a drawback that is associated with immunity to small doses of such a drug.

As a rule, the products act in such a way that the pests do not die instantly - this takes several days

Traditional methods of fighting ants

Traditional recipes are based on accessible and effective ingredients that can be purchased in a store or pharmacy at an affordable price.

Boric acid

A liquid solution or dry bait is made based on boric acid:

  • The recipe for the liquid solution is simple. Granulated sugar 55 g and 6 g of boric acid are dissolved in 60 ml of water. The finished mixture is poured into shallow containers and laid out in the most common habitats of insects.
  • You don't need water for the dry mixture. Sugar and boric acid are mixed and poured onto paper.

Ants slowly spread the poison, so all the inhabitants of the nest become infected. In small doses, boric acid is safe for humans

But you still need to be careful, especially if there are children and pets in the house

Using ammonia

The best remedy for expelling ants from the house is based on ammonia. The pungent odor of the component repels pests, which for a long time forget the way back to the home.

Against ants you need to make a solution based on ammonia. To do this, dilute a whole bottle of the drug in a liter of warm water. The resulting mixture should be shaken thoroughly. The prepared solution is poured into places where insects accumulate and into their nests, and the floor is also washed with it.

The pests immediately leave the room. The effect of the drug lasts for 3.5 months. During this time, the smell of alcohol will disappear, and if necessary, the procedure is repeated again.

Fragrances that insects cannot tolerate

Insects cannot tolerate strong odors, even those that are pleasant to humans. Therefore, the following scents are suitable for repelling them:

  • plant mint or lavender;
  • pour a few drops of essential oils, ammonia, and camphor into places where ants are most likely to enter your home;
  • wormwood and tansy help;
  • garlic, which is rubbed on a possible route of movement, will help;
  • It is useful to add a bay leaf to food products that attract insects.

Sweet water

Ants are attracted to the sweet smell, so you need to take advantage of it. Sugary drinks act as traps:

  • Leave a glass of sugar syrup on the table overnight. The insects will fall into the sticky liquid and drown.
  • Another option is to place a glass with a sweet drink in the middle of cardboard coated with glue. Insects will stick to the sticky base and die.

This method is temporary, since soon the ants will give all their relatives a signal of danger. Insects stop responding to the sweet trap.

Medicinal chamomile

A safe and environmentally friendly way to get rid of pests is medicinal chamomile. Chopped grass is scattered in the habitats of insects, as well as along their routes. Additionally, you can wash the floor in your apartment with a strong chamomile decoction.

Insects cannot stand the smell of this plant, so after two days they will not be in the apartment. In addition, chamomile is absolutely safe for all family members, including pets.

Borax, honey and glycerin

Borax, honey and glycerin are dissolved in water. All components are taken in equal parts. The finished product is applied to the surface where ants were most often seen.

Essential oils

The olfactory receptors in insects are much more developed, so any substances with an odor are unpleasant for them.

Any essential oil diluted in a bucket of water is useful for repelling. Wash the floor with the resulting solution, spray it on all surfaces and fill the nest. Eucalyptus, orange, fir or juniper oil are ideal.

"Decis Profi"

An insecticide of contact-intestinal action that destroys both adult parasites and their larvae. Available in powder form, on the basis of which a solution for spraying is prepared. For 10 liters of water, only 1 gram of the drug is enough. The effect of the insecticide appears after an hour. The treatment effect lasts up to two weeks. The prepared solution cannot be stored. It is also important to take into account that the insecticide can have a detrimental effect on bees. 1 gram of this drug costs less than a dollar.

"Calypso"

The drug is intended to combat various types of garden pests, including Lepidoptera, Coleoptera and Homoptera. Available in the form of a suspension concentrate, in a 1 liter package. The high effectiveness of the Calypso insecticide is due to its active ingredient – ​​thiacloprid. Depending on the type of pests and weather conditions, the drug protects the plant for 2-4 weeks. The composition is applied to plants by spraying. A liter of concentrate costs about $65.

Instructions for use

The powder does not need to be prepared for use. The product is scattered over surfaces. The best results can be obtained if processing is carried out throughout the site. This option is difficult to implement, so more often the powder is scattered in the habitats of bedbugs. If the manufacturer allows this possibility, prepare a solution; the ratio of water and product varies depending on the type of drug.

Preparation for processing

It is necessary to move the furniture to the center of the room and empty the cabinets of things. This will allow you to reach pests and their habitats. It is recommended to clean surfaces from dirt. This is done not so much for the purpose of cleaning the room, but to remove the clutch of eggs and husks that the faces of bedbugs shed.

Security measures

The powder is scattered around the room, wearing a respirator and glasses. You need to work with gloves. This need is due to the fact that small particles enter the air during processing, and then into the respiratory tract and onto the mucous membranes.

"Aktellik"

A popular insecticide that is sold both in ampoules and in plastic canisters. A potent product that fights mites, aphids and whiteflies. A 2 ml ampoule is diluted in 2 liters of water. The composition is used to spray all parts of plants. The product is considered toxic (hazard class 2), so you should use protective clothing when working with it. In enclosed spaces, the insecticide should be used with extreme caution; the room must be ventilated. The price of the drug averages $50 per liter.

Reasons and ways of penetration of silverfish

A prerequisite for the existence of insects is humidity. That's why creatures sneak into our apartments. There are many ways through which parasites enter a home.

Silverfish enter houses through ventilation shafts. Cracks, crevices and open windows are sources of danger. The small size of insects allows them to penetrate through holes in walls.

Objects and products contaminated with larvae or adults are no less dangerous. Silverfish can be found in books, boxes, and products. The modest size of insects does not allow them to be detected immediately, since they are nocturnal. You can only see them if you suddenly go into the kitchen or bathroom at night and turn on the light.

Insects choose those apartments and houses in which the microclimate is clearly disturbed. High levels of humidity, condensation, cracks and debris in the house are an ideal habitat for parasites. Silverfish prefer damp and warm rooms. It is not difficult for them to get into any house. If the conditions turn out to be comfortable, the pests will settle in a new place.

Your house is being attacked by woodlice!

Often our home is visited by not the most pleasant guests - insects.
Cockroaches, ants, midges, spiders, etc. - this is not the most complete list of illegal occupants. Woodlice often inhabit the kitchen and bathroom. They love places with high humidity and are difficult to get rid of. An insect such as woodlice belongs to the order of crustaceans. Their body is divided into segments that take an oval shape. Consists of the abdomen, chest and head. Active life is mainly conducted in spring and autumn. Breeding season occurs in summer.

The female woodlice carries her eggs in a pouch inside her body and lays them only when she is sure that there are no predators nearby. Woodlice are the most adapted insects of their order for life on land, but they breathe with gills.
