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.”
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.
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.”
Famous brands of Dichlorvos
Clients struggling with the problem of bedbugs in their apartments have compiled a rating of the most effective insecticides. Among the sprayers are “Varan” and “Neo”. The instructions indicate that these aerosols can be used in any home. The synthetic composition does not at all damage the surface of furniture, plastic, silk fabrics and wallpaper.
When sprayed, dichlorvos does not leave the surface of the object sticky, which is especially convenient for the buyer, plus it is easy to apply the aerosol yourself, without the help of a specialist. The invisible film covering the surface is very durable and can retain its properties for up to six months in inaccessible places.
Aerosol “Varan”
A broad-spectrum insecticide that eliminates all crawling and flying insects. Effective in the fight against bedbugs, eliminates pests in a short time. Parasites do not have protective immunity against this drug. “Varan” is not addictive to insects. The composition of the aerosol has a lemon aroma, which gives the product some advantage over other insecticides when used in residential areas. After application, the chemical properties that eliminate “bloodsuckers” are active for another 20 days, which contributes to the death of all parasites in the room. You can treat any surface with this insecticidal agent, no matter where it is located. Easy to use, it is good to use this aerosol:
- in the apartment;
- in the country;
- on a hike.
“Thanks to its unique composition, it helps a person protect himself from annoying insects. I never suspected that I would encounter bedbugs; these terrible insects can ruin my entire mood, and what’s more, they are difficult to get rid of. And in general, I read that it is impossible to remove them from upholstered furniture and carpets on your own, just throw them away, but since we live in a rented apartment, we started poisoning them with Dichlorvos “Varan”. The result was not long in coming.”

Dichlorvos “Neo”
It has also proven itself excellent among consumers. In addition to bedbugs, it remarkably eliminates:
- cockroaches;
- flies;
- ants.
It is active after use for up to 15 days, which helps get rid of all parasites quickly and for a long time. The insecticide is available in two flavors: mint and lemon. Active microgranules - plant organic compounds, risk class - third. After a few hours, you can see the first dead bedbugs.
According to reviews from most consumers, “Neo” is the most effective remedy in the fight against bedbugs.
“When uninvited guests from the entrance arrived into the newly purchased apartment from the cracks that had not yet been sealed, they were bedbugs! Glad that the bottle had the inscription “odorless” on it, I purchased a nice bright bottle of Dichlorvos from the Arnest company – “NEO odorless”. The product solved my problem without much difficulty.”
Lydia
Aerosol “Clean House”
The product has earned a lot of negative reviews among consumers for its low effectiveness. Customers note that it does not help at all in the fight against bedbugs. Only those parasites that already exist were eliminated, and not all of them. “Clean House” is a drug that only paralyzes them for a short time; it turns out that the pests do not die.
This product has a pungent odor that is absolutely safe. “Clean House” is great only for baiting spiders and flies
In reviews, consumers point out that in the fight against bedbugs it is best to purchase another, more effective product. Excellent in the fight against ants and their offspring
“I can say that for the first time in my life I encountered, perhaps, the most unpleasant insects in the world - bedbugs. The “Clean House” product did not help in the fight against bedbugs, and the money for the product was wasted.”

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.
| 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.
The effectiveness of Dichlorvos against cockroaches
The effectiveness of this product has been proven by many years of experience in its use. Due to the various variations in the routes of entry of Dichlorvos into the body of insects (through breathing, chitinous cover, oral cavity and stomach), the drug becomes truly fatal for them.
However, everyone knows about the unique ability of cockroaches to develop a kind of immunity to insecticides. Fortunately, manufacturers of modern chemicals have found a way out - they put several similarly active components into the product at once.
Thanks to this, you can safely poison insects without fear of their return. Not a single pest can withstand all pyrethroids, because they have a radically different composition and mechanism of action on the body of cockroaches.
In addition to all of the above, it is worth noting a fairly quick effect. If you follow all the rules for using Dichlorvos, it begins to act immediately and within a couple of hours most of the pest population dies. And due to the drug’s ability to have a prolonged action, none of the remaining cockroaches have a chance to survive, which also indicates its high effectiveness.
Do insecticides kill insect eggs?
The oothecae of cockroaches are less vulnerable than adults. They are very resistant to chemicals - Dichlorvos will not take them. Therefore, if there is at least one masonry left in the apartment, it is worth either destroying it physically (using a narrow nozzle of a vacuum cleaner, exposure to hot steam or, conversely, frosty air), or after a short period of time, carry out disinfestation again.
What other parasites does the drug fight against?
“Dichlorvos” is a very universal remedy that helps get rid of not only cockroaches. It can be used if there are any unwanted insects in the home: bedbugs, midges, fleas, ants, ticks, mosquitoes, flies and other pests. However, when fighting another type of parasite, read the instructions carefully, since your actions in each individual case will be slightly different.
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.
Benefits of bedbug repellent Varan
Aerosol preparations are considered the most effective, unlike traps, pastes, liquids, crayons and powders. There are several reasons why a spray composition is chosen:
- no need to prepare the product;
- it is easy to use;
- gets even from inaccessible places;
- does not leave marks on upholstered furniture;
- safe for plastic, polish, fabric and wallpaper;
- features reliable, long-lasting results;
- bedbugs do not have immunity or addiction to it;
- has a mild lemon aroma;
- safe for the environment;
- It's relatively cheap.
This synthetic insecticide is not addictive to insects. Its effect lasts up to 20 days. This allows you to get rid of even those pests that were not subject to primary treatment. After direct contact with the treated surface, the insect dies in no more than 5 minutes. It contains several main substances.
- Dimethyl dihorvinyl phosphate. It is he who most actively affects the nerves of bedbugs and destroys them.
- Tetramethrin and cypermethrin. These plant alkaloids paralyze the nerve impulses of pests within a few hours.
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.
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.
