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.”

Let's sum it up

If we analyze all of the above, we can note that the product is really effective. As reviews show, it can be used not only against cockroaches, but also other insects. Reviews also indicate that there may be situations where the drug is ineffective. Regarding the disadvantages, it is a danger to people and animals, so it is very important to follow the instructions, use protective equipment and adhere to safety measures.

Remember, when the premises are heavily contaminated, it is correct to contact specialized services. Professionals guarantee results, and you will not need to come into contact with pesticides.

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.”

Dichlorvos Varan: difference from other sprays

Pin
There are several types of insect repellent on sale. 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.

Choice of dichlorvos

Now you can buy dichlorvos in a wide range. Before giving preference to one or another insecticide, you need to know about some features.

• Varan. The drug is aimed specifically at combating cockroaches, which significantly increases its effectiveness. After disinsection, it remains active for a long time. Unlike other insecticides, it has a detrimental effect on egg laying. If the room is properly treated, repeated procedures will not be required.
• Neo, Eco. It has a universal effect and can be used against ticks, fleas, cockroaches, ants and other insects. Quite often it is used in veterinary medicine.
• Taiga. It is also a universal drug with fairly fast and effective action. After using this pesticide, the room will need to be thoroughly ventilated.
• Clean house. Refers to old drugs. Known to be a fairly effective insecticide that can clear heavily infested areas. But it is toxic and dangerous for people and pets. Requires careful use and compliance with safety precautions.

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.”

How does it work against parasites?

Pin

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.

Mechanism of action

The pesticide has a neuroparalytic effect. When active substances enter the insect’s body, the transmission of nerve impulses is disrupted. The result is paralysis of the insect, and then death. Thanks to spraying, the substance penetrates into hard-to-reach places, which significantly increases efficiency.

When treating a room, the substance is applied to those surfaces where insects are most often seen. It is also necessary to find the nests and apply the drug to them. It is quite easy to find nests indoors; it is necessary to inspect hard-to-reach places; where a colony of cockroaches lives there are feces and other remains of vital activity. It is better to carry out treatment during the daytime, since these pests are active only at night and are in shelters during the day. It affects cockroaches with toxic fumes that penetrate through the respiratory tract. The poison also enters the body through contact.

After the surfaces in the room are treated, the substance acts for a long time. Therefore, cockroaches that walk on such a surface will definitely come into contact with the poison. This leads to the fact that one cockroach, which has become dirty with poison, runs to its relatives and infects the rest of the individuals. In addition, when the parasite cleans itself, it eats the poison and it enters the intestines from where it has a detrimental effect.

For 2 weeks, the insecticide applied to the surface poses a mortal danger to cockroaches. Then its effect decreases.

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.

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.”

Actions after treating the premises

Pin

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.
