Use of Dichlorvos against cockroaches and other insects

In the fight against various insects, including cockroaches, Dichlorvos has been used for a long time: the drug has shown itself to be an effective fast-acting remedy.

Flies, mosquitoes, wasps, fleas and many other types of pests die under its influence within a short time.

Types of Dichlorvos

Modern Dichlorvos is an innovative universal product for exterminating pests. The industry produces different types of the drug. Their active components are similar, but the composition is significantly different.

Kinds

This allows you to select the version of Dichlorvos that is intended to destroy a specific type of pest. Currently popular:

1. Dichlorvos is universal. Due to the presence of several active components, the drug can be used to kill many types of insects. The difference between universal Dichlorvos and other products with the same name is the duration of action and the presence of a specific odor.
2. station wagon. To improve the characteristics of the drug, toxic impurities were introduced into its composition. Thanks to this, Dichlorvos can destroy insects not only in apartments, but also in the open air, which makes it one of the best drugs for fighting cockroaches. It is perfect for use in large rooms. The disadvantage of the drug is a strong pungent odor that does not dissipate for a long time and is easily absorbed by some things.
3. Dichlorvos "Neo". Aerosols of this brand are available in both odorless and flavored versions. The drug is distinguished by both its duration of action (about 14 days) and its versatility - it is suitable for the destruction of flying and crawling pests.

Dichlorvos brands are no less in demand - Varan, Eco, Extra and others.

Reviews about the use of Dichlorvos

Evgenia, 34 years old, Bryansk

I use monitor lizard against cockroaches as soon as I see the first pest. I begin treating the surfaces where it was found. After these manipulations I no longer see cockroaches in the apartment

Anna, 38 years old, Ufa

I often use a universal remedy for cockroaches and ants - there are a lot of living creatures in a private house. The drug of this brand helps little against these insects, because it is important to first find the nest. But Dichlorvos greatly reduces the pest population. For this reason, I use it at the same time as others.



Control of insects in the apartment and house

The desired effect in pest control can only be ensured by proper treatment of premises. For each type of insect there are some subtleties of using Dichlorvos in an apartment, since the mechanism of action of the aerosol on them has some differences.

Cockroaches

To achieve the greatest success in exterminating cockroaches, you need to know how to properly use Dichlorvos in the fight against them. It is impossible to use an aerosol to treat food or make it into a bait that pests love to eat.

Accordingly, preference should be given to treating with Dichlorvos those surfaces where cockroaches like to be. For the poison to take effect, it is necessary to provide direct contact with the pests. To do this, you need to remove the dishes and food, and then process the following in the apartment:

• walls inside cabinets and rear outer walls;
• floors near sinks, pipes, toilets;
• baseboards in areas where cockroaches have been observed;
• cracks, ventilation grilles.

Then you need to close the room and leave it. After 2.5 hours, the room should be ventilated and wet cleaned.

Does “Dichlorvos” help against bedbugs: new opportunities under the old name or a useless “puff”

The modern insecticide market is so diverse that sometimes the client gets confused by the abundance of pastes, powders, emulsions and concentrates, not knowing what to choose. At the same time, “Dichlorvos” for bedbugs, due to a number of objective reasons, remains the constant sales leader. Deserved or not?

Bedbugs in the house are a real plague of the 21st century. They enter a home in a variety of ways, and if they settle side by side with a person, then they do so seriously and for a long time. Fortunately, you can always buy an “antidote” for these bloodsuckers in a supermarket or household chemicals store. This means that when they are detected, it is not necessary to immediately call the SES or pest control service. You can try to fight back against the small “occupiers” yourself.

How does Dichlorvos act on cockroaches?

Pyrethroids are components of Dichlorvos that have a nerve-paralytic effect. After direct contact with the sprayed aerosol, the substances enter the body of insects. They penetrate the chitinous cover or the respiratory system, causing paralysis.

Baiting cockroaches

The advantage of pyrethroids is their long-lasting effects. It is enough to apply Dichlorvos in the apartment once, and it will remain on surfaces for a long time (at least 2 weeks), maintaining its properties. During this period, the aerosol will kill cockroaches, gradually reducing their population.

How long does Dichlorvos work against cockroaches?

After spraying, the drug continues to act for 15 days. If cockroaches still remain in the apartment, the treatment must be repeated.

Popular brands

The effectiveness of an insecticide largely depends on its manufacturer. There are several popular companies that have proven themselves.

"Neo"

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.

"Eco"

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.

Bedbugs

Instructions for using Dichlorvos to kill bedbugs have their own characteristics. The aerosol must be used to treat those places with which they come into contact, and these are upholstered furniture, bedding, beds, books, peeling wallpaper, electrical sockets and switches.

To find bedbug nests, you need to move cabinets, dismantle beds, and take out books. Having discovered a nest, it should also be treated with an aerosol, spraying Dichlorvos and around it at a distance of about 25 cm. Repeated treatment is carried out after a week.

Pros and cons of the product

The list of the main advantages of the chemical is:

• Practical and convenient uniform packaging;
• Ease of use;
• Low level of toxicity;
• Moderate cost. It is impossible to say unambiguously how much dichlorvos costs, since it depends on the brand and manufacturer. However, the price is always much lower than a number of other alternatives.
• Faint smell.
• There are a large number of places where you can buy the product in the right quantity and have it delivered to your home.

Regarding the negative side of the coin, the situation is as follows:

1. Without the use of special devices, dichlorvos does not penetrate into hard-to-reach places.
2. The treatment must be repeated at regular intervals.
3. Not every brand can cope with bed bugs for a long time.
4. Ineffective compared to other means.

Fleas

Dichlorvos can only be used to remove fleas when treating pet bedding, carpets, and furniture, but it should not be applied to the pets themselves.

Flea

It is necessary to spray the aerosol on the walls to a height of up to 1 m (the height of an insect's jump). After 10-12 days, the treated items must be washed in the hottest possible water, and the walls and furniture must be thoroughly washed with detergents.

Instructions for use

If you decide to use Dichlorvos against bedbugs as an elimination agent, be sure to read the instructions on the package and take precautions. Compliance with them will preserve the health of those who live with you, including pets.

• Short term move. One person should poison bedbugs with Dichlorvos. Everyone else is required to leave the premises: not a specific room, but an apartment, taking their pets with them. Just three to four hours after disinfestation, household members will be able to safely return home.
• Workwear. Wearing protective clothing is a must when performing any manipulation of this kind. A gas mask can be neglected, but a respirator will come in handy. You will also need a protective robe or any other clothing so that after treatment you can remove the “ammunition” that has been exposed to the poison and immediately put it in the wash.
• Latex gloves. It is equally important that the poison does not get on the skin. The hands are most susceptible to damage. You can protect them with household rubber gloves.

If it was not possible to protect your skin or eyes from contact with the product, you should immediately rinse the affected area with tap water.

Preparatory stage

Preparation for baiting insects includes four stages.

1. Informing neighbors. Report that you intend to treat your home for bedbugs. Perhaps your neighbors will decide to join you, thereby increasing the efficiency of the process.
2. Pre-cleaning. Place items that can absorb spray vapors in a safe place or cover with plastic.
3. Providing access. Move sofas, beds, armchairs and cabinets away from the walls. These are the favorite places of bedbugs, where they usually locate their nests. Provide yourself with unhindered access to the most inaccessible places in the house.
4. Ventilation of rooms. Open the windows wide to avoid fumes. The air circulating inside the room will become your companion. It will spread particles of poison to places where you will not be able to reach.

Processing Features

The simple process of baiting bedbugs consists of four steps.

1. Preparing the balloon. Shake the bottle so that the contents separated in it are mixed into a single substance.
2. Detection of the "enemy". Point the sprayer at the location where bedbugs are or have been previously noticed and pull the trigger.
3. Surface treatment. Apply the composition to the back of paintings that hang on the walls, to the backs of furniture (especially large cabinets that are pushed against the wall). Treat the space under the window sills, in the area of ​​all baseboards. Pay special attention to the niche under the kitchen sink and the location of the trash can.
4. Waiting for results. Leave the windows open and leave the apartment for a couple of hours.

Security measures

In Soviet times, the question of whether Dichlorvos is harmful to humans was not on the agenda. Everyone understood that it was really harmful. Nowadays, thanks to the changed formula, it is not so dangerous to health, but nevertheless it is necessary to remember that Dichlorvos is a rather aggressive drug, so it should not be allowed to get into the mouth, nose, or eyes.

The drug is also dangerous when it gets on hygiene items. Therefore, soap, personal belongings, and food must be removed before treatment with Dichlorvos.

In addition, you must wear protective equipment:

• clothes with long sleeves;
• scarf or hat;
• gloves:
• glasses.

Means of protection

People and animals are also first removed from the house. A few hours after treatment, the premises are ventilated and wet cleaning is carried out.

How effective is dichlorvos against bedbugs - TOP 5 most popular brands of dichlorvos

The appearance of bedbugs in a house brings a lot of trouble to its inhabitants. The nights become sleepless, and the skin becomes covered with bites and terribly itches. Getting rid of parasites in this case becomes goal number one. The surest way to kill blood-sucking insects is to use chemicals.

Historical reference

Even in Soviet times, dichlorvos was considered the main and accessible way to combat insects. It has not lost its popularity to this day. But how effective is dichlorvos against bedbugs? Let's look into this issue.

What is dichlorvos

Dichlorvos is an insecticide containing organic phosphorus compounds. Since this substance is low-hazard to humans and toxic to insects, it is successfully used to kill crawling and flying invertebrates.

Available in aerosol form, which is easy to use. At the moment, there is no dichlorvos (substance) in the composition of the cans.

It has been replaced with compounds that are less toxic to humans - pyrethroids. However, the name became a household name, and manufacturers did not change the word “dichlorvos”, which was familiar and recognizable to consumers, but fundamentally changed its composition. In addition, the composition may contain tetramethrin, synergist and cypermethrin, which enhance the negative effect on pests. The main difference between modern and old Soviet products is the smell. Manufacturers take care and often fill the cans with herbal aromas; it is not so strong or just odorless dichlorvos.

How dichlorvos kills bedbugs

Dichlorvos for bedbugs has a nerve-paralytic effect on insects. Upon penetration through the spiracles, the insecticide enters the hemolymph and paralysis of the nervous system occurs. As a result, the insect stops moving, the contractile movements of the abdomen stop, gas exchange stops and the individual dies from suffocation. As a rule, the toxic properties of a sprayed aerosol last for about 10-14 days.

Instructions: how to treat with dichlorvos

After purchasing dichlorvos against bed bugs, it is immediately ready for use. But you need to prepare the room. Remove food, isolate access from pets, and eliminate drafts. Before spraying, shake the can well and spray the insecticide in one layer in hard-to-reach areas and in places where insects accumulate:

Important! After treatment, leave the room closed for several hours.

Remember - insects hide in dark places where they are least disturbed. The nest can be identified by the presence of feces, skins left after molting, the presence of white oblong eggs and living larvae and adults.

Safety measures when killing bedbugs with dichlorvos

Treatment with dichlorvos against bedbugs requires compliance with safety regulations:

Pay attention to the expiration date, otherwise it will be problematic to remove bedbugs with dichlorvos. Often when buying at the market or in a small store, sellers paste a label with changed dates over the manufacturer’s sticker.

If a headache or nausea occurs, measures must be taken to prevent the spread of further poisoning:

Important! If the symptoms do not go away or get worse, you should call an ambulance. As a rule, treatment does not cause side effects if the rules described above are followed.

1. The need to process several times.
2. It takes a long time to weather.
3. With prolonged contact it can harm a person.
4. May cause allergies.

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 the condition of 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. 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.
