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.”
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.

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.
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
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.
| Name | Description |
| Varan | It has a series of drugs with broad and narrow action (only against cockroaches). Available in different scents. Lasts for a long time. Has a detrimental effect on parasite eggs. If the room is treated correctly, once is enough to get rid of pests. |
| Neo, Eco | Has universal action. The spray is used against all insects - flies, cockroaches, fleas, ticks, ants. Used in veterinary medicine to impregnate dog collars and wool. |
| Taiga | Remedy for flies, cockroaches, mosquitoes, bedbugs, mosquitoes. After processing the room, thorough ventilation is required. It works effectively and quickly. |
| Clean house | Outdated tool. It must be used strictly according to the instructions so as not to cause poisoning in humans or existing pets. Gets rid of cockroaches in a short time. |
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.
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.

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?
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.
Popular brands
The effectiveness of an insecticide largely depends on its manufacturer. There are several popular companies that have proven themselves.
The advantage of the Neo brand is that it is odorless Dichlorvos. There are also flavored options, with the smell of lemon and mint.
Dichlorvos "Neo", despite its relative safety, is a potent chemical. It contains permethrin, cypermethrin and piperonyl butoxide, which effectively destroy crawling and flying pests.
Due to its gentle action, the insecticide is used to treat livestock from psoroptosis, scabies, otodectosis, and pediculosis. But it is not recommended to treat pets - cats, dogs, rabbits - with the chemical, since their skin is more delicate. In addition, a pet can become poisoned by licking poison from its fur.
The validity period of “Neo” is 14 days, and during this time the aerosol retains its qualities. The spray is available in a 190 ml bottle, which is enough to treat a room of less than 40 m².
"Varan"
Unlike "Neo", "Varan" contains piperonyl butoxide. But, despite one more component, this drug is less effective, since the concentration of substances in it is much lower.
The effect of the insecticide lasts for 3 weeks; after this period, the treatment will need to be repeated.
It mainly fights cockroaches, bedbugs, and ants.
The main advantage of “Eco” is the smell - a light aroma of lavender. Another plus is the large volume of the cylinder – 250 ml, which allows you to treat several rooms at once.
Dichlorvos helps get rid of flies, midges, moths, as well as cockroaches, bedbugs, and ants.
Quite effective, but wears off quickly.
"Universal"
The composition includes several active ingredients: cypermethrin, permethrin, tetramethrin, piperonyl butoxide. Due to this, “Universal” is suitable for combating all types of insects. It acts quickly and helps destroy even large colonies.
"Terminator station wagon"
Like “Universal”, it is suitable for killing all types of insects, it works even in the open air, and copes well with large colonies.
However, the smell of “Terminator” is very strong, pungent, and the composition contains toxic impurities. Therefore, you should not use this brand of insecticide if there are children in the house.
The big disadvantage of this product is the pungent odor that does not dissipate from the apartment for a long time. Moreover, some things can absorb the “aroma”; it cannot be removed.
"Extra"
Dichlorvos of this brand destroys uninvited guests very well, even if their population has grown greatly. At the same time, “Extra” has a very pungent odor; it is not recommended to use it in a closed room. Leave a window or door slightly open to allow fresh air to flow in.
"Clean house"
The product under this brand is valid for 3 weeks. It effectively fights adults and larvae.
However, the substances contained in the “Clean House” lose their properties under the influence of ultraviolet radiation. Therefore, the insecticide should not be left in direct sunlight.
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:
- Close windows, ventilation grilles, and doors tightly.
- Cover the aquariums with glass and turn off the compressor.
- 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.
- Place food, toys, clothes, books, and bedding in plastic bags.
- 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.
Nuances to consider
Before disinfection, the space between the wall and the furniture must be free. Bedding and clothing should be removed from chairs and beds. It wouldn’t hurt to treat it with a steam generator and pack it in sealed bags. Particular attention should be paid to sockets, switches, household appliances, and cracks, which are best covered with cling film. Such measures will not allow bedbugs to escape punishment.
Note! Before purchasing dichlorvos, you need to know the square footage of the room and the amount of furniture in it. According to the standards, 20 g of aerosol is calculated per 1 m².
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
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.
