Signs of poisoning

Symptoms of dichlorvos poisoning differ depending on how the substance entered the human body: through the skin and mucous membranes, by inhalation, through the esophagus.

In case of contact through the skin, the following symptoms are observed:

• tingling;
• redness;
• burning;
• swelling and itching, as with allergies.

Upon contact with the eyes, a person feels:

• pain and itching in the eyes;
• redness of the mucous membrane of the eyes;
• excessive lacrimation;
• discharge from the conjunctiva.

What happens if you inhale dichlorvos in a poorly ventilated area? If a person spends a lot of time in a closed space with dichlorvos vapor, he will soon feel the following signs:

• headache;
• dizziness, poor coordination;
• cough and runny nose;
• unpleasant sensation in the respiratory tract;
• increased body temperature up to 38, sometimes up to 39 degrees;
• nausea and vomiting, sometimes extremely strong and endless.

Entering the human body through the esophagus, dichlorvos causes the most severe poisoning, compared to entry through other routes:

• vomiting is incessant and debilitating;
• severe diarrhea;
• heavy sweating;
• decreased vision;
• suffocation;
• convulsions.

Doctors divide dichlorvos intoxication into three stages:

Security measures

Thanks to modern scientific developments, the harm of Dichlorvos to people and animals has been minimized. However, if you inhale too much of the chemicals, you can cause a severe allergic reaction or even poisoning. Once in the liver, pyrethroids destroy its cells. Follow seven precautions when working with insecticide.

1. Remove children and pets from the premises. It is advisable that children and animals are not in the apartment for a couple of days after treatment.
2. Seal the aquariums hermetically and turn off the compressors. The insecticide is toxic to fish and amphibians.
3. Hide food and personal items. Pack food in cling film or sealed bags, then hide it in the refrigerator or cupboard. Do the same with personal hygiene items and dishes.
4. Remove textiles. Bedspreads, pillows, carpets, soft toys, curtains - all of this absorbs toxic substances. Remove what can be removed, cover the rest with newspapers or cellophane.
5. Protect skin and respiratory tract. Carry out the treatment in a respirator or gauze bandage. Wear gloves and tight, closed clothing.
6. Open the windows. Spray in a well-ventilated area to avoid inhaling chemicals. You need to close the windows immediately before leaving the room.
7. Ensure safe storage. If you have not completely used up the product, pack the can in a plastic bag and hide it in a place out of reach of children.

What should you do immediately after treatment?

It is important to avoid mistakes, otherwise the insects will survive. If you are studying the question of what to do after disinfestation against a bed bug, you must follow the recommendations:

• after a few hours (3 hours or more), or better yet the next day, you need to clean some surfaces of the solution;
• the chemical is removed from door handles, armrests of upholstered furniture, from the surfaces of bedside tables, cabinet handles, chairs, tables, as well as other objects that are frequently touched;
• prepare a neutralizing composition: take soap and soda, stir in water, then partially clean the surfaces.

After 2 weeks, the treatment is performed again, so there is no need to completely unpack things that are hermetically sealed with polyethylene after the initial spraying of the product.

Mechanism of action of the product

Modern Dichlorvos necessarily contains substances such as pyrethroids, which have a paralytic effect on the central nervous system of insects. They enter the parasite's body through inhalation or through food. Under the influence of pesticides, disturbances in the transmission of nerve impulses begin, which lead to paralysis of the respiratory organs with subsequent suffocation.

As it settles on the insect’s integument, the drug continues to exert its destructive effect for some time. Having reached the shelter, the parasite begins to “wash itself”, cleaning the poison from its paws, swallowing it with its jaws. As a result, the poison penetrates the insect’s digestive tract, causing severe poisoning.

It is important to know not only how Dichlorvos acts on cockroaches, but also the speed of its effect. With large-scale processing, the main part of the population dies immediately, another part - within a couple of hours.

If only a small amount of the chemical gets on the cockroach, there is a good chance that the insect will survive, especially if water is available. Therefore, treatment should be carried out with a drug that contains, in addition to pyrethroids, other active ingredients.

Instructions for use

When treating premises and clothing against bedbugs, cockroaches, fleas, and moths, several precautions should be taken:

• clear the apartment of small children and pets. It is recommended to remove indoor plants, as modern products can still harm them;
• Use protection: respiratory mask, thick long rubber gloves, safety glasses. Take clothes that are as closed as possible;
• Do not spray Dichlorvos near food, it is advisable not to use it in the kitchen or at least remove all food from the room for several days until the effect of the product wears off;
• If the chemical comes into contact with your skin, wash it immediately with clean water and soap;
• do not treat the surface near open fire;
• If the chemical gets into your eyes, rinse them immediately with plenty of water and consult a doctor;
• If symptoms of poisoning appear (dizziness, nausea, blurred vision, etc.), you need to call an ambulance.

Before exterminating bedbugs and cockroaches, an apartment or premises should be carefully prepared for treatment:

• wipe furniture and floors with a damp cloth to remove dust and dirt;
• free all corners and hard-to-reach places to process them;
• block all escape routes for cockroaches and bedbugs: close windows, doors, seal all cracks, install fine mesh for ventilation;
• remove the mattress. It should not be processed, since even after the smell has evaporated, the product will remain inside the filler, negatively affecting health.

Dichlorvos must be used as shown in the instructions on the package. The sequence of actions for all brands is approximately the same:

1. Close all windows and doors in the room.
2. Shake the can well.
3. Spray the spray, keeping it at a distance of about 20 cm from the surface. If you bring the can closer, the spray will be uneven; if you move it away, the effect will worsen.
4. After complete treatment (corners, baseboards, floors, ventilation grilles, cabinets, door jambs), leave the room for 3-4 hours.
5. When the smell dissipates a little, wipe all surfaces with a damp cloth - this will remove the “aroma” of the poison.
6. Mix 50 g of grated laundry soap, 50 g of baking soda, 5 liters of water.
7. Wipe the surfaces that the apartment residents come into contact with with a cloth soaked in the resulting solution.
8. After 3-4 weeks, carry out general cleaning: treat floors, shelves, furniture, cracks, hard-to-reach places with detergent or whitening solution (20 ml per 10 liters of water).

Attention! The aerosol only affects larvae and adults; it will not help get rid of eggs. Therefore, after the first treatment, it is necessary to re-spray the product in the room after 2-3 weeks. It is not advisable to carry out general cleaning during this time period; the chemical should remain in hard-to-reach places: in cracks, corners, under baseboards, on ventilation grilles.

Not only apartments, furniture, but also textiles are treated with dichlorvos. This should be done as a last resort if boiling, ironing, freezing, or steaming did not help. The spray kills parasites, but may cause irritation if it comes into contact with the skin.

To destroy insect larvae found on clothing and bedding, follow the instructions:

1. Place textiles in a sealed bag.
2. Spray Dichlorvos inside; it is better to choose an odorless product.
3. Close the package.
4. Leave for 3-4 hours.
5. After treatment, wash bed linen and clothes at the maximum permissible temperature, boil if possible.
6. Iron things.

Attention! Under no circumstances should Dichlorvos be used to treat underwear or clothing that frequently comes into contact with the skin: T-shirts, tank tops, trousers, jeans. It is forbidden to splash children's things with chemicals. After treatment, items should be washed several times.

Reviews

My apartment is on the first floor above the store. From there, cockroaches and ants come running to me. And recently I discovered several bedbugs. Dichlorvos Varan helped. I only had to spray the apartment once and all the “aliens” disappeared. I bought it for future use - there is no guarantee that no more insects will enter my apartment.

I believe that this is the only budget method that is available to every person. Indeed, dichlorvos costs very little, and its effect is no worse than that of expensive insecticides. I myself actively use it in the summer against flies, various insects, and bedbugs. Only when I’m cleaning, say, the kitchen, I cover everything with towels or newspapers, and then I go for a walk somewhere for 2-3 hours. Then I come, open the windows with mosquitoes and continue to live in a new way, without goosebumps.

Review of popular brands

Today there are many types of Dichlorvos. To figure out which of them are the most effective and economical, let's look at each in more detail.

"Neo" - odorless dichlorvos against cockroaches

Average cost: 90 rub.

The drug is universal for combating all types of household insects. It does not have any foreign odor, does not leave marks on furniture and is the least allergenic in the entire line. It contains three modern, potent components, enhanced by a special synergist substance.

The result of its use is visible almost immediately, but if used carelessly, it is just as dangerous as its predecessor. If the product gets on the mucous membranes, it is important to immediately rinse your eyes or rinse your mouth.

"Varan" from cockroaches

Average cost: 130 rub.

The insecticide “Varan” is universal, and its instructions state that not only adult individuals are destroyed, but also their larvae and eggs. The main feature of this drug is its long duration of action. Even surviving insects will die within 20 days from the moment the poison is applied.

"Raid"

Average cost: 350 rub.

A special feature of this brand of aerosols is its composition, one component of which enhances the effectiveness of the other. The “Raid” formula is made on the basis of a natural aqueous solvent and acts in two directions - it instantly kills insects and provides long-term protection against them for up to 1 month.

This dichlorvos also has a number of other advantages over other insecticides, namely: ease of use, cost-effectiveness and versatility of the product. However, there are several significant disadvantages: strong toxicity and higher pricing.

"Clean house"

Average cost: 95 rub.

Dichlorvos “Clean House” allows you to get rid of unwanted “guests” in record time. However, this tool is quite outdated and must be used very carefully, following all the instructions in the instructions.

"Raptor"

Average cost: 220 rub.

This insecticide against cockroaches and other crawling insects has an immediate effect, destroying everything in its path. The high effectiveness of the product is due to the presence of two strong active substances in the composition - cypermethrin and tetramethrin, enhanced with piperonyl butoxide as an auxiliary component. At the same time, the aerosol provides protection against insects for several months from the moment of treatment, without posing a danger to people and pets.

"Terminator"

Average cost: 60 rub.

The Terminator insecticide does an excellent job of baiting crawling and flying insects, and is also used to treat landing sites for flies. The proven formula works very effectively, leaving no opportunity for cockroaches to survive, and prevents the recurrence of pests. A separate plus is that this product does not have the unpleasant odor characteristic of dichlorvos.

Gel "Dichlorvos"

Average cost: 55 rub.

This form of release of Dichlorvos is convenient in that it can be used in hard-to-reach places. Thanks to the use of a gel that causes an epidemic in cockroach colonies and a spray, insects will not have any chance to survive in your apartment.

"ECO"

Average cost: 95 rub.

This type of “Dichlorvos” is quite effective in the fight against cockroaches, in comparison with other analogues. Thanks to the new generation active ingredient, it does not allow parasites to adapt and destroys a wide range of insects. Its additional competitive advantage is the pleasant aroma of lavender, which does not cause discomfort when using the product.

Advantages and disadvantages of the drug

Those who doubt whether it is possible to remove bedbugs with dichlorvos should know about the pros and cons of the drug. One of the positive aspects is the convenient release form. After all, any aerosols are easy to use, especially if you can install a special adapter that simplifies the treatment of hard-to-reach places.

Another plus is its prevalence and reasonable price - the product can be purchased inexpensively in almost every specialized store. An important factor is also considered to be that the harmful effects of the drug on the human body have been minimized by the efforts of manufacturers.

The disadvantage is considered to be ineffective when the premises are heavily infested with parasites. This means that it is unlikely that dichlorvos can get rid of bedbugs that have appeared in large numbers in the apartment. Even repeated treatments may not bring the desired result. In addition, it usually takes a lot of time to process the premises. To avoid the risk of poisoning, in some cases furniture is disinfested in the fresh air. Often it has to be disassembled to do this.

Chemical composition

The goal of all dichlorvos is to reach and poison every nearby insect, which is why they are famous for their terrible, unbearable smell. The main rule when using after spraying is to leave the room for a certain amount of time and ventilate well before returning, as side effects, including poisoning, are possible. Dichlorvos NEO does not have a bad smell; instead, you can choose from floral aromas of roses, lavender and lilac.

Previously, demethyl dichlorovinyl phosphate was added to dichlorvos as the main substance. Today it has been replaced by permethrin and cypermethrin, which help in the fight no worse, but are less harmful to human health. It is important to remember that any dichlorvos is dangerous. The composition of the substance does not end there; it includes: piperonyl butoxides, aliphatic carbohydrates, dimethyl sulfoxides, ethyl alcohol.

Why doesn't Dichlorvos kill cockroaches? Major versions

You need to understand how to properly use aerosol in an apartment. The efficiency of processing will depend on this.

Aerosols - droplets quickly settle and evaporate. It is better to use emulsion forms

It is believed that aerosol preparations are most effective for mild to moderate infestations. When sprayed, toxic substances quickly settle on the surface and evaporate. This helps to quickly reduce the life of the product.

Liquid emulsion “Fas”

Some modern insecticides are no longer effective, because cockroaches have developed resistance to them. There are also toxic substances that are not aggressive enough in nature and cannot help remove insects from the object. Carrying out disinfestation will not yield results - the longhorned beetles will survive.

It is possible that not all cockroaches will be affected by the insecticide.

The ability of cockroaches to adapt at the genetic level. Its manifestations

Insects have increased adaptability to various negative factors. This is due to the characteristics of the organism: individuals are omnivores and can tolerate difficult weather conditions (temperature changes, humidity).

To understand whether Dichlorvos kills a cockroach, you should know that such insects have increased sensitivity. They communicate with each other through smells, pick up signals from their relatives, and they themselves can also sense danger.

Each cockroach has its own irritability: on some, Dichlorvos may not have any effect at all
