How does dichlorvos Varan act on cockroaches? Is the product sufficiently effective? Safety precautions when working with aerosol

Man has been fighting cockroaches for a long time. These insects carry dangerous diseases, cause allergies and skin diseases. Domestic parasites have adapted to living near humans and have developed an addiction to toxic substances.

People also improved insect repellents. Previously, Dichlorvos was used, which coped well with the task, but had some disadvantages.

Now his improved formula, called “Varan”, is ready to destroy uninvited guests with great success.

What is dichlorvos?

During the Soviet Union, a product was used against household pests based on the active ingredient dimethyldichlorovinylphosphate, abbreviated Dichlorvos.

The drug was toxic to various insects and domestic animals. There was severe discomfort when using Dichlorvos, due to the strong smell of kerosene.

There was also a remedy against domestic parasites - dust. But it had little effect on cockroaches, and had a toxic effect on humans.

The modern insecticide has retained its formidable name, but has improved its composition. The product is available in different forms - as a soluble concentrate, plastic strips impregnated with a chemical, and an aerosol. Efficiency in the fight against domestic parasites remains at a high level.

Tatyana, Kemerovo:

“My parents used dichlorvos in childhood, when they lived in a dormitory. The terrible smell remains in my memory to this day. The modern drug has a different aroma, is similar to an air freshener, and is effective against cockroaches. Once was enough. Then, as prophylaxis, they did it after 2 weeks. The dog tolerated it well, there were no changes in behavior or health.”

Description of the product "Varan"

If we consider dichlorvos, which was used previously, we can note its effectiveness. It was a fairly strong insecticide and could cope with large colonies of Prussians. But it was quite toxic and dangerous not only for cockroaches, but also for pets. In addition, it had a very pungent and unpleasant odor, which was difficult to remove from the room, which brought discomfort, especially in residential areas.

Speaking of the modern version, an improved formula is used here, which made it possible to develop an effective drug that has many advantages. Today it can be purchased in different release forms, so everyone can choose the appropriate option depending on the situation.

Chemical composition of Varan

Modern Dichlorvos Varan contains artificial pyrethroids and auxiliary agents (solvents, aromatic substances). Previously, Dichlorvos contained organophosphorus poisonous compounds that were toxic to mammals.

Pyrethroids are more gentle substances for humans and pets. Similar substances are found in chamomile flowers. It is no coincidence that it was previously dried and used against domestic parasites.

The new generation Dichlorvos contains not one, but several pyrethroids with different chemical structures. This guarantees the death of pests not from one or another poison. A rare situation occurs when a population of cockroaches has developed an addiction to several pyrethroids at once.

Thanks to fragrances, the anti-cockroach product has a pleasant aroma of citrus or pine forest. It won't be difficult to treat a room with such a smell.

Arina, Yaroslavl:

“When selecting a remedy against cockroaches, the seller recommended dichlorvos Varan. It is inexpensive but effective. According to the seller, the composition has changed compared to Soviet dichlorvos, which had a terrible smell. I will try a new product with an old name.”

Composition and active substances

Artificial pyrethroids are used as active substances, which ensures effectiveness and at the same time safety. They are not so dangerous for pets, but are destructive to cockroaches and other insects.

Regarding pyrethroids, they can be compared to a natural substance found in the well-known chamomile. And, by the way, it is a folk remedy in the fight against cockroaches. The effectiveness of the drug lies in the fact that it contains not one active substance, but several. They all differ in chemical structure. Many have heard that cockroaches have the ability to develop immunity to pesticides, but in this case such a possibility is excluded. Because if one poison does not work, the second will definitely kill the pest. It should also be said that the modern drug has a pleasant aroma and will not cause discomfort.

Dichlorvos Varan: difference from other sprays

There are several types of insect repellent available on the market. It's not easy to understand them. It is better to choose those that are aimed exclusively against cockroaches.

The remedy Varan has an advantage over other drugs, since it acts not only on adult individuals, but also on egg laying. This ensures the destruction of the entire parasite colony.

How to deal with bedbugs

Dichlorvos
Unlike ants and mosquitoes, bedbugs frighten residents of the house with their appearance, bite and spread diseases such as fever, typhus, and tularemia. The goal of the little bloodsuckers is to drink as much blood as possible. When attacked, the insect can inflict more than 500 bites.

The appearance of parasites in the house causes moral and physical harm. Therefore, the issue of combating them is very relevant.

You can get rid of misfortune in the following ways:

• folk remedies;
• with the help of specialist disinfectors;
• treating the premises with chemicals.

The last option is universal and is considered the most affordable, since it does not cause problems with the purchase of drugs. Products for the destruction of parasites are sold in retail and online stores. Represented by pencils, aerosols, traps, powders, repellents. When working with each of them, it is important to read the instructions and comply with safety requirements. The simplest and most affordable method of killing bedbugs is odorless dichlorvos.

Positive and negative aspects of the drug

Each product has advantages and disadvantages in use, dichlorvos Varan is no exception.

The “advantages” of Varan are:

• low price;
• accessibility to purchase;
• efficiency in use;
• quick results;
• long-term action due to the formation of a specific film, upon contact with which previously surviving individuals die;
• no traces when spraying.

The main disadvantage when working with the spray is the need to use personal protective equipment when spraying.

Vitaly. Ryazan Oblast:

“I used the latest generation Varan. Didn't make an impression. The Soviet one was probably of better quality. Smells good, but has zero effect. At first the baleen disappeared, but two weeks later they crawled again. Do they really need to be washed twice a month now? The composition has changed - the quality has dropped, I think so. It has become less toxic for people and for cockroaches too.”

Answers to popular questions

As most users of the Dichlorvos aerosol write on the Internet, this drug quickly and permanently kills various types of fleas (Pulex irritans, Ctenocephalides felis, Ctenocephalides canis, etc.).

This product has many varieties, so each resident can buy the most suitable insecticide for themselves.

Today, many users ask various questions about the use of Dichlorvos, the main ones are listed below.

Does Dichlorvos kill fleas?

So that residents have no doubt that Dichlorvos definitely kills fleas, they must first carefully study the principle of action of this product.

Such an aerosol acts in this way: when these parasites land on treated furniture or other surfaces, their nervous system first stops working, and then complete paralysis occurs, leading to the instant death of the bloodsucker.

Dichlorvos instantly and permanently helps residents get rid of bed or other types of fleas. This aerosol poisons adult fleas and their larvae, but is harmless to small eggs and bloodsucker pupae.

It should be noted that such a drug is identical to other aerosol anti-flea insecticides, because the pupae and eggs of many domestic parasites are well protected from poison by a durable shell.

Thus, after 1-3 weeks, the resident must repeat the sanitization of the infested home in order to kill all the fleas that hatch from eggs and pupae during this period.

The domestic flea aerosol “Dichlorvos” has a low price, but in terms of quality it is no worse than its imported counterparts. Today this drug is considered the most common insecticidal agent.

There are many positive reviews about this aerosol on the Internet, which once again confirms that it really works well against fleas.

Why doesn't dichlorvos help?

Dichlorvos kills all fleas in your home only if the household has treated all your pets - a cat, a dog, etc. Otherwise, fleas will soon appear again in an apartment or private household.

Also, the resident must first carefully study the instructions for using this drug, and then strictly follow the specific recommendations contained therein. After all, the final result of sanitation depends on the method of applying such an insecticide.

Is dichlorvos safe for people and animals?

Dichlorvos is considered an insecticidal agent of hazard class 3 out of 4. This means that it is moderately dangerous. However, a person can also be poisoned by this drug if they do not follow specific precautions.

One more point should also be noted: when used correctly, Dichlorvos is safe for residents and animals, but not for pet fish and reptiles.

Sometimes this product is used to treat the fur of specific farm animals to kill ticks and other parasites on them. However, if there is a dog or cat in the house, they cannot be treated with Dichlorvos.

When using such an insecticidal preparation, the resident must always follow all necessary safety precautions.

How does it work against parasites?

Toxic substances in modern Dichlorvos produce a nerve-paralytic effect on insects. Once inside a cockroach, the poison disrupts the transmission of nerve impulses, which leads to paralysis and then death of the insect.

An aerosol (spraying from a can under pressure) forces the toxic substance to penetrate into the most inaccessible places. This application is more effective than continuous liquid. Toxic air will penetrate everywhere.

When treating a room, a person must ensure that the toxic substance gets into places where insects frequent. They can be detected by characteristic traces of feces.

It is better to process there during the day, when they are guaranteed to be in shelter. Cockroaches are nocturnal insects; they prefer to sit out during the day and travel at night in search of food and water. In this case, the poison will penetrate through the spiracles into the respiratory system of the cockroach, spread throughout the body, leading to the death of the parasite.

Also, the poisonous agent has a contact effect, that is, it must get on the body of the cockroaches. Through the shell, the poison will penetrate the pest’s body, causing paralysis and the rapid death of the parasite.

When deposited on the surface of the floor, upholstered furniture, walls, the active toxic substances will remain active for a long time (provided that wet cleaning is not carried out). Running through such areas, insects stain their whiskers and paws with poisons.

While cleaning off the adhering substances, the parasites swallow the particles, which leads to fatal poisoning. This is the intestinal route of exposure to dichlorvos Varan.

Most pyrethroids retain their active toxic properties for 15 days. The effectiveness is then reduced due to the decomposition of the substance in the air.

Therefore, the instructions do not recommend wet cleaning in areas treated with aerosol. For about two weeks, the treated areas reliably poison domestic parasites.

Reviews

Sergey, 43

We had the following situation: we came to visit our grandmother and saw that new “tenants” had appeared. Grandmother is already old and, of course, it is very difficult for her to carry out any events. My husband and I decided to take our grandmother home with us for a week, while we ourselves began to fight the Prussians. We bought Varan because the seller highly recommended it, and we didn’t regret it at all. We sprayed the product in the evening and went home. In the morning before work, we looked in and were scared, to put it mildly, because there were a lot of corpses. Within a week, they came and cleaned, and within a week the apartment was clean.

Olga, 36

I used Varan for moths. I just didn’t know what to do anymore, I used both tablets and sprays, the result was the same, first they disappeared, then they appeared again. So I decided to try dichlorvos. I treated the cabinets, carpets, furniture, and sent warm clothes to the dry cleaner. I am very pleased with the result, no moths for several months now.

Oleg, 45

Varan did not impress me and I am dissatisfied with his actions. I processed everything according to the instructions, did everything as it should. At first I actually removed the corpses of cockroaches, and they disappeared, but the result did not last long, because after about 2 weeks they were running around the kitchen again. The effectiveness of the old dichlorvos was many times better.

Mode of application

To reliably destroy domestic parasites, you need to know how to use the spray correctly and take into account some features of use.

The instructions recommend:

1. Close windows, ventilation grilles, and doors tightly.
2. Cover the aquariums with glass and turn off the compressor.
3. Clear cabinets, shelves, drawers for processing. Move upholstered furniture, tables, and refrigerators away from the walls and raise mattresses. Remove carpets from the walls and remove them from the floor.
4. Place food, toys, clothes, books, and bedding in plastic bags.
5. Shake the can several times, spray first in hard-to-reach places, crevices, cracks, under baseboards, beds, and furniture. The aerosol should be kept at a distance of 20 cm from the surface.

Important! You need to work quickly to avoid inhaling toxic substances.

One can of Varan is enough to treat a small room with furniture. If you need to poison several rooms with a kitchen, you will have to use several pieces.

How to use Dichlorvos against fleas in an apartment

According to user reviews, getting rid of fleas with Dichlorvos in an apartment is simple - just treat the apartment according to the instructions and allow the product to activate its effect. The instructions involve preliminary preparation of the apartment and the use of protective glasses and a mask to avoid contact with the drug with the mucous membrane.

So, the aerosol is sprayed at a distance of 30 cm from baseboards, floors, and furniture. It is also important to treat cracks and crevices where parasites can hide. do not forget to spray the drug in the closet and closets (clothes must first be packed in bags).

In fact, this is a universal drug that helps get rid of not only fleas, but also other parasites. Most variations of the product do not have a specific odor (updated formula, for example, Varan) and are completely safe for humans. According to the instructions, the product does not leave marks or streaks, which greatly facilitates the process of treating the apartment. You can buy it in any specialized store or order it online.

Precautionary measures

Although the drug Varan is considered harmless to people and pets, it is a good idea to take safety measures:

• The treatment must be carried out in protective clothing that will cover the entire surface of the body;
• It is necessary to close the respiratory organs. It is better to use an industrial respirator. But you can use a gauze bandage. If you experience a sore throat or dry cough while working with an insecticide, you need to leave the room and breathe fresh air. This symptom is an indicator of penetration of a toxic substance into the throat;
• Eyes must be protected with glasses. If the product gets on the mucous membrane, rinse immediately with plenty of water;
• You cannot spray a toxic substance into the technical openings of electronics - televisions, computers. The action of some components of toxic drugs will negatively affect the operation of these devices.

If you take precautions, the risk of poisoning is significantly reduced.

Svetlana, Nakhodka:

“We rented a cottage on vacation. There were a lot of cockroaches there. We noticed only at night, when the lights were turned on, and they began to scatter. We bought Varan dichlorvos at a nearby store. We thought it would smell disgusting, but it turned out to be a decent product. We also got rid of flies and other insects along the way. The mosquitoes didn’t bother me either, although they were near the lake.”

Sprays and aerosols

Both sprays and aerosols are airborne agents that are sprayed into an infected room and act on the bug with the air.
However, a bedbug spray is usually a concentrated substance that must be diluted with water before use. It can be sold in small bottles or canisters. Aerosols for bedbugs are ready-made preparations placed in disposable cans under pressure. Their use does not require any preliminary preparation.

Aerosols for bedbugs

“Raptor” contains three active ingredients at once, thanks to which a high degree of damage is achieved. It is safe for animals and children. According to reviews, this product gives good results only with a low degree of infection and generous spraying.

Photo of Raptor aerosol: “Clean House” - contains cypermethrin as an active ingredient. It is safe for children and animals, however, if it enters the human body it can cause poisoning. The effectiveness is confirmed by reviews of people who were able to destroy all bedbugs using the substance.

Photo of the aerosol Clean House: “Combat” - produced in two types: only for crawling insects, or for crawling and flying ones. It has a good smell and is not dangerous to people.

Photo of the Kombat aerosol: “Raid” is a universal preparation for fighting insects; it can also be used for bedbugs. Reviews report good effectiveness with a low degree of infection. However, it has an unpleasant odor and leaves behind stains.

Photo of the Reid aerosol: “Dichlorvos” is a well-known and affordable aerosol. When processing, be sure to remove all people and animals from the premises. Many people often ask “Does Dichlorvos help against bedbugs? Is it possible to kill bedbugs with Dichlorvos? Indeed, this remedy does not always work effectively.

Therefore, if Dichlorvos did not help you, pay attention to other sprays and aerosols

Photo of Dichlorvos aerosol: Bona Forte is a preparation made from natural ingredients. It has almost no odor, so immediately after airing you can return to the apartment.

Photo of Bona Forte aerosol: “Antiklop” is a substance based on three active components. Non-toxic, retains strength for several months. According to reviews, it successfully destroys bedbugs.

Bedbug sprays

Many sprays are intended for professional use only and cannot be found in stores.

“Executioner” is one of the most popular products, produced in Germany. It is distributed in small bottles - for a large apartment you may need 15-20 of them.

Photo of the product Executioner: “Tetrix” is an effective substance intended for professional use. One bottle is enough to treat two rooms. It has a very strong toxic odor, so after use you need to thoroughly ventilate the room.

Photo of Tetrix: “Cucaracha” is an analogue of “Tetrix”, designed for independent use. Retained the unpleasant smell of its predecessor.

Photo of the product Cucaracha: Get is a product in microcapsules that is effective for several weeks after use. In addition, one of the few has a contact effect against bedbugs running over it. Has no smell.

Photo of the Get product: Sinuzan is a professional substance reminiscent of Tetrix. Highly effective, however, also has a strong unpleasant odor.

Photo of Sinuzan: Karbofos is a well-known drug against bedbugs. Available in the form of powder, concentrate, emulsion or finished product. Affects all types of insects, including eggs. It has an unpleasant odor that lasts for a long time.

Actions after treating the premises

After spraying the poisonous agent, you need to leave the room for at least 3 hours. If possible, do not return longer. When you return, you need to ventilate the room for about 30 minutes; the concentration of the toxic substance will begin to decrease. Clothes in which the room was treated must be washed.

All shelves, cabinets on which food and things need to be laid out will have to be washed. It is advisable not to wet clean the entire space. Wipe with a damp cloth only those places that will come into contact with human hands. Sweep away dead insects.

Certain types of pyrethrodes are dangerous for cats. Make sure your pets don't eat dead cockroaches. Cats can get seriously poisoned. The first signs will be increased salivation and trembling. Animals need to be seen immediately by a veterinarian.

Flaws:

• Difficulty in quality processing. Due to the low concentration of the composition, the desired effect can only be obtained by spraying the entire area infested with bedbugs;
• Short active phase. The effect of gaseous compounds ends at the first ventilation.

Features and action of the product

A drug based on pyrethroids - when contacted with chitinous covers, the poison instantly causes damage to the nervous system and death of the insect. The effect after application is noticeable within 15 minutes, the death of all insects occurs 8 hours after spraying.

Pyrethrins are naturally occurring insecticides produced from the flowers of plants in the Asteraceae family. Varan aerosol contains synthetic analogues of the substance; the compounds are more active and photostable.
