Dichlorvos for cockroaches: how to poison correctly

For many centuries, cockroaches have coexisted with people, constantly trying to penetrate their homes and causing many problems and inconveniences with their presence. That is why the issue of getting rid of these insects is still very relevant today.

Unfortunately, cockroaches have very successfully learned to adapt to all kinds of insecticides. This makes their complete eradication from residential premises a very difficult process. At the moment, there are several effective methods of pest control, but one of the most popular and successful over the years has been and remains the use of Dichlorvos. It is this miracle remedy that will be discussed in our article.

What is Dichlorvos?

Dichlorvos is a product that destroys and kills insects. Dichlorvos contains poisons called pyrenoids; they act on the cockroach as a nerve agent that immobilizes the insect’s muscular system. Paralyzed cockroaches die quickly. The poison begins to act on the cockroach only after it has inhaled the vapor. The composition is in a spray bottle and is easy to use.

When treating a room, toxic chemicals kill only cockroaches, flies and other insects, while no harm is caused to humans or animals when sprayed. The organophosphorus composition instantly kills unwanted insects, while quickly decomposing in the external environment without causing damage even to plants.

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.

How does Dichlorvos work against cockroaches?

For the cockroach repellent to take effect, you must:

Find the nest or location of the cockroaches, and then spray Dichlorvos around and directly into the habitat.
You can accurately spray directly onto the insect.
Another effective method is to apply the product to furniture and baseboards, where cockroaches most often appear.

The more Dichlorvos is applied to the cockroach habitat areas, the more effective the product is. Each insect that is affected by the spray transfers the poison to its fellow insects.

Efficiency of using Dichlorvos

Sometimes people notice surviving cockroaches in a room after pest control. Therefore, they are quite naturally interested in the question: does Dichlorvos help against cockroaches?

It is impossible to answer it unambiguously. This product has proven effective for spot treatment. However, if its concentration is insufficient, individual insects can survive and establish a new population. Therefore, it is advisable to combine Dichlorvos with other, less volatile agents with a long residual effect, for example, with a gel.

Are modern Dichlorvos effective?

Modern Dichlorvos are definitely effective, progress does not stand still and the products improve their composition every year. It becomes more poisonous to cockroaches and less smelly and unsafe for humans and animals.

Modern industry on the Dichlorvos market offers a wide selection of drugs, all of them are not much different from each other, because their main active ingredients are similar. The composition of modern products includes: cypermethrin, esfenvalerate, permethrin, vaporrin, tefluthrin and other active poisons.

The store presents such brands of Dichlorvos as: Neo, Eco, Universal, Varan, Super.

Do cockroaches die from Dichlorvos?

Yes, of course, cockroaches die from Dichlorvos, but not immediately. The substance needs time to act on the insect’s body. You cannot see the immediate effect when spraying. Unfortunately, it happens that one treatment is not enough. This can happen due to the fact that, in addition to adult cockroaches, they lay eggs in different corners and clutches. Consequently, after some time, young offspring begin to hatch from the eggs and Dichlorvos did not affect them, since the embryos were in a cocoon.

It is for this reason that repeated treatment and spraying is carried out in places where masonry is laid. If there are no pets or children in the room who can lick up the toxic chemicals of Dichlorvos, it is better to postpone cleaning and washing the floors for a couple of weeks. Over time, the substances will dissolve in the air and stop working.

How quickly does Dichlorvos act against cockroaches?

To date, Dichlorvos remains the most effective means of removing cockroaches. Due to its properties, it kills insects quite quickly. Within 10 minutes of contact with the insect, depending on the concentration, it dies. If an insect transfers the composition of the product to another fellow insect, then the life of the pest ends within a couple of hours.

Does Dichlorvos kill cockroach eggs?

Some people who use the product believe that Dichlorvos is not effective, as they notice the return of cockroaches to the premises. Although this is not true, because an adult who has felt the effect of the aerosol dies. The reappearance of cockroaches means that the insect previously left the clutches and new offspring hatched that did not interact with the poisons.

In most cases, it has been proven that Dichlorvos has too little effect on cockroach eggs, so we can say that it does not kill cockroach eggs 100%. The eggs are in a so-called capsule, which is not affected by water or chemicals; moreover, such a larva can survive frosts down to -11 degrees.

But in the modern composition of Dichlorvos, manufacturers guarantee the killing of eggs in the larva. It all depends on the concentration of the product in the affected area. Cockroaches are very prolific and their effective removal completely depends on the destruction of clutches. It is best, after the main treatment with a disinfectant, to go through the area where cockroaches accumulate again after a few days, since the birth of new young insects is possible.

Is the spray harmful to humans and pets?

The composition of Dichlorvos contains pesticides, but their action and concentration mainly affects only insects. There are precautions for humans and animals to avoid exposure to aerosols. Of course, if you specifically spray Dichlorvos on a person or animal, you can cause a negative reaction, most often it can be difficulty breathing and irritation of the mucous membranes; if it comes into contact with food, vomiting and diarrhea are also possible.

In some cases, allergies and itching of the skin occur, nausea and vomiting are possible if the product was accidentally licked from the treated area by an animal or child. To avoid unwanted symptoms, animals and children should be removed from the premises for some time during treatment and disinfection. When processing, be sure to open the windows and ventilate the room.

Does dichlorvos kill cockroaches?

Under certain conditions, cockroaches die from dichlorvos. But whether it is possible to remove cockroaches with dichlorvos is another question. Now let's look at the mechanics of the process.

Aerosol chemistry affects Blattella germanica in three main ways:

Penetration of DV through the chitinous membrane, resulting in paralysis of the nervous system
Fumigation effect (through respiratory pores)
Poisoning through the digestive system (contact with treated surfaces, poisoned food and water).

It is important to remember that the first two methods are activated only when the product comes into direct contact with the cockroach’s body!

With a successful combination of all factors, a cockroach that is “drunk on dichlorvos” dies on average in 15-20 minutes. The time of death varies from several minutes to several hours and even days. But in practice, most cockroaches come into contact with poison indirectly, receiving a non-lethal dose of poison. As a result, they run around poisoned for a long time until they finally die or the poison is removed from their body.

Dichlorvos can have a so-called “knockdown effect”: cockroaches fall “as if dead” within 30 seconds after forced contact with the poison. However, this is the end only for a small part of the individuals. The rest, having come to their senses, will run to drink water.

Interesting fact Experiments show that when there is a large concentration of cockroaches, the use of aerosol cans helps to achieve a more pronounced and lasting lethal effect. Conversely, the effect of dichlorvos on cockroaches at low numbers is ineffective, since aerosols do not have a prolonged effect.

It is also important to remember that dichlorvos does not affect cockroaches that are in the egg stage, because pyrethroids do not have an ovicidal effect.

Composition of "Dichlorvos"

All types of Dichlorvos contain a synthesized chemical pyrenoid; this is the most effective substance for killing cockroaches for a long period. The composition also includes piperonyl butoxide, permethrin, flavors, various types of preservatives and fragrances. At home, it is recommended to spray the “Neo” and “Varan” brands of Dichlorvos. They are less harmful and toxic to humans and pets. Other formulations and products may cause adverse effects due to the strong odor of chemicals.

Former composition

The basis of Soviet Dichlorvos is an organophosphate insecticide. The old composition had a terrible odor for humans, which definitely caused discomfort and made it impossible to stay in the room for some time after treatment. In addition, there were such types of chemicals as: cypermethrin 0.2%, permethrin 0.2%, tetramethrin 0.2%, dimethyl sulfoxide, piperonyl butoxide 1.0%, corrosion inhibitor, propane, butane, isobutane, isopropyl alcohol.

New line-up

It is a proven fact that insects mutate very quickly and adapt to external changes, including pesticides. Therefore, the old formulations of the product today are not as effective as before. Modern manufacturers are constantly working to improve the quality of Dichlorvos.

The main direction is a higher concentration of poison and a less pungent odor for humans. The basis of modern Dichlorvos is pyrenoids. They are less toxic to humans and warm-blooded animals, but are more effective at killing insects. Do not forget that the absence of odor or pleasant aroma from modern Dichlorvos still requires precautions; it is just as poisonous as its previous version.

Composition and varieties of “Dichlorvos”

The drug was the first among similar products to be sold in stores, and it appeared on the shelves more than 30 years ago. The basis of “Dichlorvos” of that time was dimethyl dichlorovinyl phosphate; it was packaged in aerosol spray cans and did an excellent job of controlling any type of insect pest. The product could kill cockroaches at home and in the country, but its harm to humans due to toxicity was also significant.

Modern insecticides under the brand name “Dichlorvos” also help get rid of insects, but the active substances in them are completely different. Almost all of them are based on the action of synthetic pyrethroids - artificially created insecticides, analogues of natural pyrethrins. By the way, chamomile contains natural pyrethrin, so it has a detrimental effect on a number of insects. Often the products contain inexpensive but effective cypermethrin, as well as permethrin, tetramethrin and other substances.

The most common types of Dichlorvos on store shelves are:

Varan
Neo
Eco
Super, etc.

“Dichlorvos” against cockroaches of our time and the one that was produced earlier work differently, but their effectiveness is approximately equal. But the toxicity of the active ingredients of the modern product is much less - even if it accidentally enters the human body, severe poisoning will not occur. However, many “Dichlorvos” contain additional poisons and harmful additives, so they still need to be used very carefully.

ATTENTION: Now many types of “Dichlorvos” are produced odorless or even with a pleasant aroma. It must be remembered that this is achieved through the inclusion of fragrances in them, and not due to a reduction in toxicity.

Modified dichlorvos

Cypermethrin

Cypermethrin is the world's leading insect control compound. It can be used both indoors and outdoors. The main advantage of the product is its high resistance to direct sunlight and heat. It contains strong poisons that are also harmful to humans, so it should not be used without special training and instructions. The product is used by specialized insect control companies.

Piperonyl butoxide

Piperonyl butoxide is a chemical with toxic properties that is found in more than one and a half thousand agricultural, household and industrial chemicals.

Permethrin

Permethrin is an effective antiparasitic substance. It is used in formulations for treating surfaces against ticks, fleas, cockroaches, as well as for external use on human skin to disinfect viral infections.

Safety precautions

Dichlorvos is not capable of causing serious harm to health. Poisoning with this drug is most easily tolerated by people, a little worse by pets. Piperonyl butoxide, which is part of many sprays, has a negative effect on the well-being of rats and mice. All pyrethroids are poisonous to reptiles, cockroaches, and fish.

Warm-blooded animals, having inhaled Dichlorvos vapors, become aggressive, they exhibit hyperactivity, and noticeable tremor of the limbs.

Preparations containing a mixture of permethrin and cypermethrin are practically safe for humans (hazard class 3). In rare cases, they may cause redness and burning if they come into contact with the skin.

To avoid unpleasant consequences, disinfestation with Dichlorvos must be carried out while wearing gloves, tight, closed clothing, and a respirator.

Spray manufacturers mask the unpleasant odor with fragrances. Despite the pleasant aroma of the drugs, during processing you can easily inhale the vapors of the poison. At the first signs of illness, you must leave the room and go out into the fresh air.

Which dichlorvos to choose

Each user chooses the best cockroach repellent for himself. They vary slightly in price and all claim to kill insects. The difference may be in the smell of the product and the method of application. You also need to pay attention that if you use only one product for a long time, cockroaches can get used to it and develop immunity, so they often use several varieties and brands together or in sequence, depending on the reaction of the parasites.

Spray "Varan"

The cost of the spray is 79 rubles. It contains components that allow you to quickly and permanently get rid of cockroaches. After treatment, it not only kills, but also manifests itself in a residual property, which means a long absence of insects.

Spray "Neo"

"Neo" is the most recognized and effective spray against cockroaches. It has almost no specific odor, but despite this it is very toxic to insects. When it hits an individual, it kills it in almost seconds and scares away other unwanted animals. The only drawback is that cockroaches get used to the aerosol over time and its effect does not affect them. The average price of Dichlorvos is 70 rubles.

Clean house

The price on the market for the “Clean House” anti-cockroach product reaches 450 rubles, and it is not the cheapest product with unambiguous responses. The manufacturer offers a release form in the form of spray, powder, chalk, gel and traps. There are convenient attachments for treating hard-to-reach areas. It has a pleasant smell.

Raptor

, proven in the market. The effective composition fights crawling insects well and kills cockroaches. Active poisons such as tetramethrin and cypermethrin paralyze the insect, killing it. The cost in the store of the product is 365 rubles.

Raid

Aerosol against cockroaches is aimed at killing insects. Contains toxic chemicals. They allow you to quickly get rid of unwanted “guests”. It is easily sprayed onto the insect habitat, destroying both adult individuals and their clutches. Without smell. Cost 215 rubles.

Dichlorvos gel against cockroaches

Dichlorvos gel against cockroaches is an insecticidal agent. The basis of the product is fipronil. The drug is less toxic to humans. The effect on cockroaches is a paralytic agent, which allows you to kill the insect within 8 hours. The gel is in a special syringe; it is applied in a thin line along the entire perimeter of the room, as well as on furniture and corners where cockroaches appear. Cost 45 rubles.

Manufacturers of odorless Dichlorvos

In the Russian Federation, many companies produce a drug called Dichlorvos. The most well-known odorless insecticides for cockroaches are:

Dichlorvos Neo odorless produced by Arnest OJSC, Stavropol Territory, Nevinnomyssk;
Odorless dichlorvos from Force Guard;
Dichlorvos Ot odorless manufacturer Rubit;
Dichlorvos-Universal "Mr. Volt WITHOUT ODOR" from Chirton;
Dichlorvos odorless Varan manufacturer Sibiar.

Proper use of Dichlorvos

Instructions:

Use cockroach repellents as directed.
Do not spray the aerosol onto an open fire.
Do not break the integrity of the cylinder and do not throw it to avoid an explosion.
Beware of direct sunlight on the packaging, the container is under pressure.
Do not spray in the presence of children or animals.
Avoid contact with hands and mucous membranes.
Work with Dichlorvos wearing gloves and a mask.
Do not spray on food.
After handling, wash your hands and wash your clothes.
Store in a dark place out of reach of animals and children.

How to properly treat a room?

Before starting treatment, it is necessary to remove animals and children from the premises. Furniture should be covered and textiles that may come into contact with the skin should be removed. Remove food items. If possible, move furniture away from walls and corners to free up all hard-to-reach places as much as possible and identify the breeding ground for cockroaches. Dichlorvos has a very strong odor, so it is better to open the windows.

How much does it erode?

Before processing, it is best to immediately open the windows in the room, as the pungent odor can cause an immediate headache. The treated room is completely evaporated within 2-3 hours with the window open; complete disintegration of the chemicals can take weeks.

Safety rules when working with Dichlorvos

It is important to use rubber gloves and a respirator mask. Avoid contact with eyes and food. Spray at a distance of 20-30 centimeters and at arm's length, in this case you get minimal contact with clothes and face.

How to use the product correctly

You can successfully poison cockroaches with these chemicals at home only if you follow all the instructions and rules for their use. In order to carry out disinfestation most effectively and avoid negative consequences, follow our advice:

Remove all residents, including pets, from the apartment or private house.
Remove bed linen and personal items. Pack food and dishes in plastic bags, roll up carpets and place them in a corner. If possible, move furnishings away from all walls and close windows tightly.
Shake the can of the product very thoroughly and spray it at a distance of 15-20 cm from the surface in the favorite places where insects live, such as: cracks in the floors, holes under baseboards, wallpaper and furniture, around doors and window frames, behind pipes and radiators, in in and behind kitchen cabinets, near sinks and under pipes.
After spraying is completed, immediately leave the living space for at least 3-4 hours - the longer you are gone, the more effective the destruction of insects will be.
Upon returning home, be sure to thoroughly ventilate all the rooms (initially it may smell bad or stink, but this unpleasant aroma will disappear fairly quickly) and immediately do a general wet cleaning to prevent the risk of poisoning.

Despite the fact that “Dichlorvos” is effective against cockroaches already from the first treatment, it is advisable to repeat all the above manipulations with a break of 10 days. This way you will be able to achieve the greatest efficiency in pest control and will be sure that even single individuals did not survive.

Tip: a small part of cockroaches, after treating the premises with an insecticidal aerosol, as a rule, escape to neighbors through the ventilation openings. Therefore, to prevent them from returning after a couple of weeks, it makes sense to place traps in the indicated places, apply crayons or gels with a longer action.

What to do in case of poisoning?

In case of poisoning, you must leave the room for fresh air. If poisons enter the body, it is necessary to induce vomiting and after a few hours drink a laxative to remove the poisons from the body. In case of contact with the mucous membranes of the eyes, rinse the eyes with cold water. Do not enter the treated area for several hours until the product wears off.

Usually, if poisoning occurs, a person returns to full normalcy within 3 days, even if no additional first aid is taken. But you shouldn’t wait until everything goes away on its own; if the symptoms of poisoning continue for several hours, you should consult a doctor for help.

Description of the drug

The earlier version of Dichlorvos was more toxic. The composition included a substance from a group of organophosphorus compounds called dimethyl-dichlorovinylphosphate. It is distinguished by its aggressive effect on the human body. For this reason, Dichlorvos was no longer used. For marketing purposes, the name of the product has not been changed. The modern version of the drug contains various pyrethroids. This is a multi-component product, due to which it has an effect on different insects. There is no risk of harm to humans (provided the instructions for use are followed).

Chemical composition

Dichlorvos Neo, Varan and other varieties differ in composition. At the same time, the minor components differ, in most cases the active substances are the same:

cypermethrin is a second generation pyrethroid, the substance has a mild odor, is poorly soluble in water, which should be taken into account when using Dichlorvos against cockroaches and other insects, there are different types of this substance, they differ in isomeric composition (alpha-cypermethrin, beta-cypermethrin, etc.). d.);
tetramethrin is another insecticide of the pyrethroid class; when treating a room, the destruction of insects occurs under direct contact; this substance does not withstand the influence of solar radiation and begins to deteriorate;
permethrin is a type of pyrethroid, it is a direct analogue of the natural insecticide pyrethrum, this substance can be used to treat ectoparasites;
piperonyl butoxide is an auxiliary component of insecticide-based preparations; the substance enhances the effect of the toxic components listed above; its function is to inhibit the mechanisms in the body of insects that are aimed at destroying pyrethroids.

Additionally, the drug contains components that do not exhibit insecticidal activity: ethyl alcohol, fragrances, preservatives, stabilizers.

How does Dichlorvos work?

The principle of operation of the drug is based on the properties of various insecticides. For this reason, the level of effectiveness and mechanism of action of different types of products differs. Cypermethrin is a contact substance. This means that this compound provokes the rapid death of pests, but provided that this component gets on the chitinous covers of insects. This disrupts the functioning of the nervous system. The pests gradually lose their motor activity, resulting in paralysis and death soon after.

Cypermethrin is resistant to ultraviolet radiation. In comparison, tetramethrin breaks down in the sun. However, this substance retains its properties when heated. Tetramethrin enters the pest's body through inhalation, along with food. The mechanism of action is similar to how cypermethrin works. This similarity is due to the fact that these substances belong to the same group of insecticides.

Permethrin destroys the nervous system of parasites. This substance most effectively eliminates ectoparasites (insects that live on the human body), however, as part of Dichlorvos, it is used less frequently for treatment against lice and ticks. Piperonyl butoxide enhances the effect of insecticides.

Pros and cons of the product

Positive traits:

speed of action, which is due to the release form (produced in the form of an aerosol);
complex effect on pests: insecticides can enter the body of insects through inhalation, along with food and through direct contact - through chitinous covers;
moderately aggressive effect on humans; in comparison, dimethyl dichlorovinyl phosphate is more toxic and may pose a health hazard;
the components in the product decompose at the end of their service life, without generating toxic waste, which makes the product safer for the environment;
it is permissible to use the product near plants without harm to them;
Dichlorvos is an innovative, universal drug that helps destroy various pests;
long period of action of active components: insecticides remain on surfaces after treatment of the room for 1 month.

Minuses:

the product takes a long time to erode;
treatment must be carried out several times to get rid of insects.

The danger of dichlorvos

The composition of the aerosol can may vary depending on the manufacturer, but the main toxic component is always present. Therefore, the substance belongs to the third level of toxicity in relation to humans.

If a substance is low toxic, this does not mean that it cannot be poisoned. This happens in cases of violation of safety measures or use of the toxin for other purposes. If you stay indoors after spraying the composition, you can get seriously poisoned.

Toxins will enter the bloodstream, swelling of the nasopharynx and respiratory tract is possible. If a person is prone to allergic reactions, an attack of suffocation is possible.

Dichlorvos is especially dangerous for cats. They do not have a large body weight, so the concentration of the toxic substance in their blood can be very high. As a result, the animal dies or gets serious liver disease.

In case of poisoning by vapors of the substance or its accidental entry into the esophagus, severe headache, dizziness and fever up to 39 degrees may occur. In addition, signs of an allergic reaction may occur:

Runny nose;
Dry cough;
Swelling of the larynx and nose;
Skin rashes accompanied by itching and burning.

With a small concentration of poison in the blood, the symptoms go away on their own within a few days.

Dichlorvos is an old and proven remedy for killing unwanted insects. If used correctly, it will not harm either humans or pets. And harmful insects will leave the house for a long period.

How does Dichlorvos affect cockroaches?

For treatment to be effective, you need to know the behavior, reproduction, and vital functions of cockroaches. For example, what places do they live in and what do they eat? As a rule, these pests are found near sources of moisture and heat. Therefore, most often they can be found in the kitchen and bathroom. It is the presence of moisture that is a prerequisite for a comfortable life for an insect.

So, to use dichlorvos against cockroaches, you will need instructions for use. In accordance with the recommendations, you need to stock up on protective equipment. Namely, gloves, a mask, a protective suit and goggles. When using odorless products, do not underestimate the harm that they can cause if they come into contact with the skin or if excessively inhaled.

It is important to know how to properly poison cockroaches in an apartment with dichlorvos:

There should be no people or pets inside the premises;
Windows and doors must be tightly closed during the application process;
Personal items, dishes and food must be placed in some kind of container or tight bags;
First of all, places where the pest accumulates are treated, and only then the rest of the territory;
Remember about hard-to-reach places inside cabinets, behind radiators, the space between furniture and the wall, gaps between the baseboard and the floor, the space under household appliances;
At the end of the main treatment, leave the room closed for 2-3 hours;
It is important to thoroughly ventilate all rooms, even if the smell is not very noticeable.

The methods of using drugs in the form of a spray are similar, only the active ingredients may differ.

If the previous treatment was not carried out carefully, then the remaining individuals could acquire immunity to certain substances. Therefore, when re-processing, slightly different insecticides are used or alternated.

You can buy the spray at your nearest hardware store, large supermarket chains and online sites.

Dichlorvos against cockroaches has a recognizable appearance, so you will not have any problems buying it. The bottle comes in a volume of 200 ml and has a characteristic red and yellow design. The price varies around 80 rupees, which makes this insecticide quite affordable.

To make sure whether the drug is effective in controlling household pests, you can read consumer reviews.

Irina

Dichlorvos works great against cockroaches, although reviews about it are quite varied. We live next to a refrigeration plant, so we often fight with wandering Prussians, and this spray is great for finding hard-to-reach places and the space under the sink, since traps alone are not always enough.

Michael

There were a lot of cockroaches at the dacha, my mother-in-law recommended dichlorvos. Having found out how much it cost, I bought it without hesitation. A few days later, my wife and I sprayed the whole house, but the effect was questionable, dichlorvos only scares them away. Because a month later they came back again and we had to order professional treatment.

We suggest you familiarize yourself with: A small hole in the ground

Oleg

Due to the fact that my friends and I often had get-togethers in my garage, cockroaches infested it. I bought several cans, sprayed the garage and closed it. In the evening he came and ventilated. A week later, I did a general cleaning and vacuumed, while the Prussians were not observed.

Of course, reviews are not always an indicator of effectiveness, so it is best to study the composition and active ingredients. Expensive drugs are not always more effective, because the price may depend on the brand.

It is known that “Dichlorvos” appeared on store shelves more than 30 years ago, and even then the famous aerosol began to fight against unpleasant insects. Compare derivatives of current drugs and those of that time, the composition and effect are significantly different.

The original component was more effective and did its job better, but was harmful to the human body. “Dichlorvos” for cockroaches, reviews of which concerned a product based on dimethyl dichlorovinyl phosphate, claim that it was more effective, the insects disappeared quickly and never returned.

The name “Dichlorvos” remains, but dichlorvos itself - dimethyldichlorovinylphosphate - is not in it. But, despite this replacement of components, the product did not lose its effects, it only became a little weaker and does not cope with its purpose as well.

If you spray in places where there are large concentrations of insects, the end result will be maximum. It is important that the parasites come into direct contact with the poison or inhale a sufficient amount of aerosol vapor. This is necessary because insect poisoning occurs through the respiratory tract.

When a cockroach enters the body, the insecticide immediately begins to act on the nerve endings, gradually disrupting the transmission of nerve impulses. The result is suffocation, paralysis and death.

Insects that were lucky enough not to inhale the poison fumes, or that got too little of them, can survive, and this is another reason for repeated treatment and the parallel use of other means.

Although the description of the product may indicate that it also kills bed bugs, you need to understand that these insects are much more tenacious than cockroaches, and it is unlikely that it will be possible to remove them completely with aerosols.

You can buy the product at almost any hardware store or specialized online store. Its price varies around 100 rubles.

In order for the cockroaches that are in the house or apartment to die, you must follow the rules of use. All details are described in the instructions prepared by the manufacturers. Company representatives note that a number of issues are being studied more closely. After all, only those housewives who have done everything correctly will be able to understand whether dichlorvos will help against domestic cockroaches.

Before using an insecticidal aerosol, they study reviews and carry out preparatory measures:

All residents and pets are removed from the house or apartment, since active substances can cause poisoning.
If there is a terrarium or aquarium in the house, then cover it with a lid. For additional protection, use polyethylene film.
Food, bedding and clothing are placed in containers or plastic bags. They are removed from the premises.
If the furniture comes into contact with the supporting structure, then it is moved back a little so that the active substances penetrate everywhere.
Floor coverings and carpets are cleaned. They are processed outside. For this, appropriate components and compositions are used.
Window openings and doors are sealed to prevent arthropod pests from leaving the house.
Cabinets and tables are opened to allow active substances to penetrate inside. After all, cockroaches often hide in closets.

Treatment

As soon as the preparation is completed, they proceed to the treatment of premises infected with arthropod pests. Shake the can before spraying the aerosol. Spraying is performed at a distance of 40–50 cm from the face. When sprayed correctly, insecticidal components also reach hard-to-reach places. Spraying is carried out at a certain distance from floors and objects.

In order for the drug used to be effective, all actions are carried out in the prescribed manner:

Corners and space behind furniture.
Skirting boards.
Areas under bathtubs, sinks and pipes are most attractive to cockroaches.
The place where the trash can is installed.
Ventilation holes.

How quickly you can deal with arthropod pests depends on how thoroughly the treatment is carried out. If the colony of arthropod pests is numerous, then the treatment is carried out 2–3 times. Experts recommend using different chemicals to prevent insects from adapting.

Preparation for processing

Before you begin treating your living space with Dichlorvos NEO, you should do some preparatory work.

Remove people and animals from the premises so that they do not breathe toxic fumes.
Remove indoor plants to a place protected from aerosol.
Place in a plastic bag and place personal hygiene items, dishes, toys, and bed linen in a closet.
Warn your neighbors that you are going to treat them with Dichlorvos against cockroaches or bedbugs.
Prepare personal protective equipment: gown, gloves, mask or respirator, goggles.
Close windows and doors in the apartment tightly.
Move or disassemble furniture in advance, raise mattresses, remove baseboards, that is, facilitate access to secluded places where insects like to accumulate.

After all preparatory activities have been completed, you can begin disinsection of the premises.

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:

Close all windows and doors in the room.
Shake the can well.
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.
After complete treatment (corners, baseboards, floors, ventilation grilles, cabinets, door jambs), leave the room for 3-4 hours.
When the smell dissipates a little, wipe all surfaces with a damp cloth - this will remove the “aroma” of the poison.
Mix 50 g of grated laundry soap, 50 g of baking soda, 5 liters of water.
Wipe the surfaces that the apartment residents come into contact with with a cloth soaked in the resulting solution.
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:

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

How to find the best remedy?

Looking at the shelves of specialized stores, it is very difficult not to get confused and choose the best product. The range of inhibitors is truly amazing. Today, in addition to aerosols, you can purchase:

traps;
gels;
crayons;
powders;
smoke bombs.

All of them have their adherents and have fairly high performance indicators. How not to make a mistake and choose the optimal remedy?

Purchase cockroach control products only from specialized stores or supermarkets. Do not make purchases in places of unauthorized trade from dubious sellers, lured by incredibly low prices. These simple rules will save you from the risk of purchasing counterfeit goods, the benefits of which are unlikely.

If you have an urgent need to kill cockroaches here and now, then the Dichlorvos aerosol can will do the job perfectly.

In just a few hours you will be able to get rid of uninvited guests. This product will help remove insects from the most inaccessible crevices and nooks. In addition, the pricing policy of manufacturers is quite loyal.

For a reasonable price, you can easily purchase a truly productive drug and solve the problem with annoying tenants.

Note. Dichlorvos does not affect cockroach nests. Therefore, to achieve 100% results, it makes sense to carry out cyclic treatment of the room, with a frequency of 10 - 15 days. If you follow some simple rules, after just 3 steps, you will get rid of mustachioed insects once and for all.

How to properly treat a room?

Before starting work, the aerosol can should be shaken thoroughly.

The aerosol should be used from a distance of 20 cm. It is necessary to begin treatment from places where the Prussians accumulate under baseboards, under window sills, and in kitchen cabinets. They also prefer to live in household appliances, stoves, ovens behind sinks.

Peeling wallpaper and cracks under tiles are real refuges for mustachioed residents. It would not be a bad idea to spray the aerosol on the walls, floors, ceilings - wherever the cockroach trails are.

Effect on insects

Modern manufacturers of Dichlorvos also indicate in the instructions that this product has an effect on cockroaches and simply kills them outright.
Is it so? Let's try to figure this out. Next, we will consider the types of “Dichlorvos” for cockroaches, reviews from those who have tried them. Modern ones are made on the basis of synthetic pyrethroids - these are artificially created insecticides, they are analogues of natural pyrethrins. For example, this substance is found in ordinary chamomile. Manufacturers can also add cypermethrin to Dichlorvos; permethrin is a cheap component that does the job perfectly.

Only by using a certain “Dichlorvos” against cockroaches or by studying reviews about it, can you draw some conclusions and decide whether it is worth using at all.

The chemical industry does not stand still, and scientists have discovered that some pyrethroids can have a more active effect on cockroaches than regular dichlorvos. Products based on them have a longer effect on insects and are much safer for the human body, and they have practically no odor.

Gradually, such products as “Raptor”, “Raid”, “Kombat” began to appear on the chemical market, and they practically replaced “Dichlorvos”, and they give it less and less preference. But fans of this product have been actively using it since Soviet times. Even with such an assortment of safer analogue tools.

Dichlorvos “Neo” for cockroaches, reviews and components of the product:

Permethrin.
Cypermethrin.
Piperonyl butoxide.
Fragrances and solvents are additional components.

Consumers have an almost unanimous opinion about this “Dichlorvos” for cockroaches. Buyers claim that this company is of sufficient quality and destroys all unpleasant insects on the spot. It is used not only to fight cockroaches, but also other unpleasant insects: ants, bedbugs, beetles. They say that a few procedures are enough to solve the problem.

Dichlorvos “Varan” for cockroaches, reviews and composition of the product:

Dimethyl dihorvinyl phosphate.
Tetramethrin.
Cypermetrinn.

These components are sufficient to paralyze the nervous system of pests.

“Dichlorvos” for cockroaches without odor has also received considerable reviews. For this product, consumers recognized that it is one of the top sellers. Most of the reviews are positive. People who have tried it claim that the insect quickly paralyzes and dies. But this product has too concentrated a composition and aroma, and in some cases this leads to allergic reactions: cough, headache, runny nose, dizziness. Despite the fact that the manufacturer claims there is no odor.

Most comments are positive. It all depends on the degree and scope of the problem. In more advanced situations, additional drugs and several repeated disinfections were required.

In general, this dichlorvos “Varan” copes with its purpose, you just need to be careful about personal safety and try to have minimal contact with the product and not inhale the sprayed particles.

The main function of the components is a nerve-paralytic effect on pests. The treated insects quickly absorb the product, and a reaction begins in their body: nerve impulses are disrupted, after which paralysis immediately appears, and then the insect dies.

The owner’s main task is to treat the cockroaches with the drug as much as possible so that a sufficient amount of harmful substances enters his body.

The sprayed product enters the insect's body through the respiratory tract. Then the poison penetrates the hemolymph and spreads, only then the insect dies. Dichlorvos should be sprayed on large concentrations of pests and on the places where they most often live.
With this manipulation, sprayed particles settle on the chitinous covers of cockroaches. Upon contact, the product penetrates the internal part of the body.
Particles of the product also fall on the surfaces of furniture and floors, and if you do not carry out wet cleaning for some time, the properties will be preserved and will also act. After running over the poisoned surface, small particles remain on the legs and antennae of the cockroach. Then, hiding in his shelter, he begins to clean them, while using insecticides. This amount is enough to poison and kill the insect.

“Dichlorvos” for cockroaches, reviews of which have already been reviewed by consumers, are sold in any household stores, they can be easily purchased, and the cost of the funds is quite low.

To reliably destroy such “uninvited guests” with the help of Dichlorvos, you should take into account all the nuances from the instructions and be able to use it correctly. This will make the treatment more effective and safe for pets and apartment dwellers. Before you start fighting insects, you should remove all children and pets from your apartment or house, and then prepare properly:

If there are aquariums in the room, they are tightly covered with special glass (ideally it should be taken out of the house) and the compressor is turned off. This will prevent air from the room from entering the water. This rule should be observed, since the inhabitants of the aquarium, like all living beings, are sensitive to the active substances of Dichlorvos.
All doors and windows are closed. In this case, it is necessary to ensure that there are no gaps. If they are, it is better to plug them with cotton wool.
All dishes and food from the cabinets are removed (you don’t have to take them out of the refrigerator, since nothing gets into it). It is advisable to take such things out onto the balcony. If this is not possible, everything is placed in thick plastic bags (preferably double ones).
The gas or electric stove, refrigerator and freezer, as well as other interior items and household appliances are moved away from the wall. If other rooms are involved in the treatment against crawling parasites, then the carpets are rolled up (on the walls too), sofas, cabinets, armchairs, etc. are moved away. at least 10 cm from the wall.
Children's toys (especially soft ones, which absorb odors well) are placed in double plastic bags and placed on the balcony.

Dichlorvos is especially effective in areas with the largest concentrations of baleen insects. Then you need to shake the can well and remove the cap. The hole in the aerosol must be directed in such a way that the stream from the can goes out towards the cockroaches.

Basically, one can of Dichlorvos is enough to treat one average room with an area of approximately 15 sq.m. If there is a need to get rid of such parasites in the rooms and kitchen, then you need to use 3-4 aerosols at once.

Immediately after surfaces are treated with insecticides, you should leave your home for several hours. This rule must be followed even if such information is not in the instructions for use. Once you are home, open all doors and windows to thoroughly clean. All surfaces must be thoroughly wiped to ensure that insecticides do not get on food or come into contact with pets and family members.

We suggest you familiarize yourself with: Buy Phenaxin powder inexpensively

In addition, it is advisable to use preventative medications against cockroaches. For example, special crayons together with trap houses will destroy individual representatives of these insects that remain alive. As a supplement to such a preparation, you can use adhesive strips that are placed in places where cockroaches accumulate. It is best to take a comprehensive approach to solving such a problem; this will allow you to quickly destroy such “uninvited guests.”

Despite the fact that Dichlorvos of modern production have a rather safer composition than the insecticide that was produced in Soviet times, they still have slight toxicity. This means that you need to be extremely careful when working with them. As a rule, not all of these points are specified in the description of the drug, but compliance with them will prevent unpleasant health consequences for people and pets. What measures should be taken to ensure that the composition in the can does not cause harm? For this:

The treatment must be carried out in clothes that cover the legs, arms and most of the body. This precaution will minimize contact of the insecticide with the skin.
You should also use protection to prevent Dichlorvos from entering the respiratory tract. A special bandage made of cotton wool and gauze will be a good help in the fight against cockroaches. When treating premises, you should definitely take into account that if you feel an unpleasant taste in your mouth or a very sore throat begins, it means that your respiratory organs need protection.
If the first symptoms of deterioration in health occur (rash, redness, shortness of breath, etc.), you should stop all actions to destroy the “uninvited guests” and try to go out into the fresh air.
It should be taken into account that some insecticides included in the modern Dichlorvos line can be toxic to cats and dogs. It is best to remove these pets from your home for at least a week. In addition, animals should not be allowed to eat dead insects. This can lead to dire consequences for the health of your cat or dog. If you notice that your pet has begun to shake and is drooling profusely, immediately take the animal to the veterinarian. There are all the signs of poisoning with the components of Dichlorvos.
This drug should never be sprayed into technical holes in home appliances. We are talking about a laptop, system unit, TV, etc. Even if you are sure that insects have made a home inside the electronics, this should not be done! Devices may stop working due to exposure to such substances.

Conclusion

It is possible to get rid of cockroaches using Dichlorvos (reviews confirm this), especially if we are talking about a small number of insects. In more advanced cases, they can be removed using several disinfection approaches. Before starting the procedure, you should carefully study the instructions provided and try to stay in the treated area as little as possible. And after disinfestation, thoroughly ventilate the room, and, having gotten rid of the “unpleasant neighbors,” do a wet cleaning and clean the surface.
