4 types of dichlorvos for bedbugs: how to choose the best one, instructions for use

Most people associate dichlorvos with a toxic substance that has a strong toxic odor. But everyone knows that aerosols are effective against harmful insects that have settled in the house.

Dichlorvos for bedbugs contains pyrethroids, which quickly destroy parasites by disrupting the activity of the nervous and respiratory systems of bloodsuckers.

These components are practically safe for the human body. In addition, the new products do not have a pronounced unpleasant odor, are accessible, affordable and easy to use.

Composition of dichlorvos and principle of action on bedbugs

The effectiveness of the product is explained by the fact that it contains synthetic pyrethroids. These can be different substances, for example tetramethrin, permethrin, etc.

Some products contain several similar compounds, which increases the effectiveness of the drug. Previously, dimethyl dichlorovinyl phosphate was used as the active ingredient, which gave the drug its name. This compound is considered toxic to humans. The name “dichlorvos” is traditionally used for all aerosols against cockroaches and bedbugs, although the active substance has changed.

The product kills insects. The active substances affect the nervous system of cockroaches and bedbugs, due to the blocking of impulses, paralysis occurs and organs fail, then the death of the parasite occurs.

In this case, the drug is released in the form of an aerosol, ready for use. This helps fight insects especially effectively, since a fine suspension is sprayed into the air. One part of the latter ends up on various surfaces, and the other immediately penetrates the respiratory system of bedbugs. Later, the toxic mixture, deposited on horizontal surfaces, also enters their body through the chitinous integument and the parasites die.

Unlike cockroaches, bed bugs do not feed on food scraps. These are blood-sucking insects. To get rid of them, you need to carefully treat the surfaces with which the parasites come into contact. To do this, several procedures are carried out, since the active substance is considered less effective compared to older developments (although the level of safety for humans has increased).

The effect of the drug sprayed during treatment lasts for 2-3 weeks.

What precautions should be taken during processing?

Despite the fact that dichlorvos is safe for humans, nevertheless, when working with it it is necessary to follow safety precautions:

• Use personal protective equipment.
• Avoid contact of the aerosol with the eyes, mucous membranes, wounds, ulcers, scratches.
• After finishing work, wash your face and hands with soap and rinse your mouth with clean water. If possible, take a shower.
• If large areas are being treated for a long time, then every 40 minutes it is recommended to take a 10-minute break, during which you need to breathe fresh air.

Types of dichlorvos

You can remove bedbugs using various means, especially since dichlorvos is produced by many large brands specializing in household chemicals. The following aerosols have proven themselves to be effective:

1. "Neo". Development of the Arnest company. The main advantage is the absence of odor. But the line even has flavored varieties - they smell like mint or lemon. "Neo" is one of the most potent drugs. With its help, you can poison insects more effectively, since the product contains substances that facilitate the penetration of toxins into the body of the parasite.
2. "Clean house". Contains less radical substances compared to Neo. They can be destroyed by ultraviolet radiation. But the effect lasts about 3 weeks, so the drug is effective against larvae.
3. “Triple Strike” only helps in case of direct contact with insects, but is harmless to humans and pets.
4. "Combat". A whole line of products, and 2 of them - “Super Spray” and “Super Spray Plus” - are designed to combat bed bugs.
5. "Raid" is a spray that contains 2 active ingredients - prallethrin and cypermethrin. But bedbugs develop resistance to them, so the product can only be used for minor infestations, since repeated treatment is ineffective.

There are other drugs, for example dichlorvos "Extra". Despite its effectiveness and the fastest possible results, it has a strong odor.

Reasons why dichlorvos is ineffective

In some cases, the use of dichlorvos is effective and helps to cope with parasites, but in other cases, on the contrary, the expected result does not occur. This depends on the following reasons:

• preparation for processing was carried out poorly;
• When inspecting the apartment, not all insect nests were discovered, since the female can lay eggs in different places and sometimes they can be located separately from the nest;
• no reprocessing was carried out;
• errors were made in the use of the aerosol - spraying was carried out from a long distance or the duration of spraying in each area was not maintained;
• General cleaning was carried out ahead of time.

Which one is better to choose?

It is difficult for a non-specialist to figure out which dichlorvos is better, since the products work almost identically and have common advantages and disadvantages.

Dichlorvos against bedbugs is the most effective drug.

It is recommended not to purchase general-purpose drugs, but to buy those varieties that are designed specifically to combat bedbugs. Universal types rarely help fight parasite larvae.

Products that are considered enhanced have proven themselves to be effective. Trade names certainly contain the words “Super”, “Plus”, “Forte”. Such options destroy bedbugs even after the first treatment. But you need to read the instructions carefully. Some products are so strong that a person can move into an apartment only a week after disinfection, and sometimes it takes longer.

Night insect repellents are considered a lighter option; the concentration of the active substance is reduced. They don’t help against bed parasites, but they do kill stink bugs. You can enter the room 2-3 hours after the treatment.

Trade marks

The group produces dichlorvos against several types of bedbugs: Neo, Innovative and Eco. They differ from each other in packaging volume, smell and combination of pyrethroids used:

1. "Dichlorvos Neo" is produced in aerosols of 140, 190 and 600 ml. The largest volume bottle is equipped with an extension tube for treating hard-to-reach areas. The packaging promises that the product is odorless, but in fact there is still a minimal smell; after airing it quickly disappears. Insect protection lasts 30 days.

2. “Dichlorvos innovative” differs from the previous product in being even less toxic to people. This safety was achieved using substances similar in composition to natural pyrethrins. Bottle volume 400 ml.
3. “Dichlorvos eco” 140 ml contains cypermethrin, a rather strong substance that persists for a long time in areas of treatment. Has a light lavender scent.

Dichlorvos “Varan” is produced against bedbugs; it is represented by two types: Varan A and Varan Forte. Their composition is approximately the same: in Varan A the percentage of poisons is higher, but Varan Forte contains an amplifier. The line also includes a special product Varan Antiklop, its composition is completely identical to Forte.

On store shelves you can occasionally find dichlorvos No. 1, which is produced by Krasnodar. The active ingredients used are similar to the Varan brand; this drug also has no odor.

How to treat an apartment with dichlorvos

The algorithm of actions for housing processing will be as follows:

1. Before starting treatment, clean the surfaces and open remote areas that should also receive the aerosol. Dishes and personal hygiene items are removed from the room.
2. Although dichlorvos only affects insects, it causes irritation and other allergic reactions in humans upon contact. It can also have a negative effect on the respiratory system, so you need to wear gloves, a respirator and safety glasses when using the product. It is better to work in closed clothing so that drops of dichlorvos do not get on the skin.
3. The product is released in aerosol form. Such a cylinder must be held at a distance of 20 cm from the surface to be treated. Then you can achieve a uniform distribution of the substance. If you keep it higher, the processing efficiency will decrease and the consumption will increase.
4. After the procedure, you should leave the room, having previously closed the windows and doors.
5. After a few hours you can enter the room, but only ventilate it first.
6. It is recommended to wipe the surfaces with a damp cloth. Then after cleaning and airing there will be no unpleasant odor left.

It is necessary to shake the can of the drug and spray the product in hard-to-reach places.
General cleaning after treatment with dichlorvos is carried out only after 2-3 weeks, not earlier.

Dichlorvos is used only for mildly infested apartments. When there is a bedbug infestation, you need to look for another method to get rid of the insects. Moreover, it is better to call specialists who use more complex methods of influence.

Instructions for use

Before treating a room with an insecticide, you should be properly prepared. All rooms need to be dusted and then ventilated. You need to remove the curtains from the windows and hide all the food in the refrigerator or cabinets.

It is necessary to free up hard-to-reach places. Windows and ventilation ducts must be closed. All people and animals should be removed from all rooms.

How to use dichlorvos? The can must be shaken several times. Then the stream is directed to places where bedbugs accumulate, holding the bottle as far as possible from the face.

The following areas must be treated with the spray:

1. furniture;
2. bin;
3. cabinets;
4. baseboards;
5. window sills;
6. corners;
7. carpets;
8. paintings;
9. shells;
10. floor.

How to get rid of bedbugs with dichlorvos so as not to harm your health? After spraying the spray, you should leave the room for at least 30 minutes.

It is better to enter the room when the smell has completely disappeared.

After treatment, you need to ventilate the room for 60 minutes. Then you should do a wet cleaning of your home. Clothes and bedding should be washed in very hot water.

Danger of the product for humans

Insects die from dichlorvos, but the drug is considered relatively safe for humans. But there is always a risk of poisoning or an allergic reaction. When inhaled, insecticides of this type cause nausea and dizziness. Coughing is considered a sign of either respiratory irritation or an allergic reaction.

In people prone to developing cardiovascular diseases, blood pressure may change, and sometimes tachycardia appears.

Is the remedy effective against parasite eggs?

Toxic substances cannot harm bedbug larvae, since the latter are well protected by the outer shell. Therefore, the owner of the apartment will have to carry out additional treatment, waiting until the new generation of insects has grown enough, but does not have time to lay eggs. The procedure is performed 10 days after the first one.

Bedbug eggs are a problem due to which they cannot always be eliminated indoors the first time.

Active ingredients

The action of modern dichlorvos is based on the insecticidal effect of pyrethroids. This substance can penetrate the nerve cells of insects and cause paralysis. The drugs cause almost no harm to humans and warm-blooded animals; they all belong to hazard class 3-4. This means that caution is only required when applying the product and for the first few minutes until the spray droplets have completely settled.

Pyrethrins were originally extracted from Dalmatian chamomile flowers. Now they are produced synthetically, thanks to which it has been possible to increase the effectiveness of the drugs up to 900 times, improve resistance to sunlight and extend the period of action after application.

It is possible to effectively poison bedbugs with dichlorvos due to the presence of the following substances in the composition:

• Tetramethrin 0.04 – first generation pyrethrin. The synthetic version of this substance is not far removed from chamomile; it also easily decomposes in the sun, and due to long-term use, some insects have become resistant to it. But tetramethrin is the safest (class 4) insecticide.
• Permethrin 0.4 is a more modern insecticide, belongs to the 2nd generation of pyrethroids. It is characterized by faster action and long-term protection – up to 20 days.
• Piperonyl butoxide (PPB) 0.3 is a substance with low toxicity for bedbugs. PPB is added to insecticides because of its ability to increase the effectiveness of pyrethroids several times, accelerating the death of insects by 2-5 times.

Advantages and disadvantages of the drug

Dichlorvos is a product that has both positive and negative characteristics. Important benefits include:

• the ability to use a product for prevention (for example, if the housewife knows that bedbugs have appeared in a neighbor’s apartment, she can treat her home in order to prevent the invasion of parasites);
• availability - even the best dichlorvos is inexpensive;
• no traces after treatment;
• versatility (the product is also effective against cockroaches, flies, mosquitoes);
• relative safety for humans and pets;
• lack of resistance to the pyrethroids included in the composition.

In addition, dichlorvos is used sparingly. The cylinder is enough to completely treat the apartment.

However, the product has a limited duration of action. It does not exceed a week. The greatest effect can be achieved only with focal treatment.

The product will not help if you spray it all over. In addition, since modern active ingredients are considered less toxic, the treatment will have to be repeated several times.

About efficiency

Let's summarize: will dichlorvos help against bedbugs? It will help, but this is only a means by which you can destroy all parasites that fall into the aerosol spray zone.

It's very easy to use, leaves no residue, and is harmless to people and pets, all at a great price. Dichlorvos can be safely used as a preparation for primary treatment, during which adults, larvae and eggs that enter the access zone will be destroyed.

After this, it is recommended to use a more potent remedy with a long-term preventive effect, which will prevent the invasion of new generations of parasites that survived the “gas attack” in the form of well-hidden eggs.

Customer Reviews

Olga, 38 years old, Ryazan: “When bedbugs appeared in the apartment, I didn’t even know what to do about it. At first I tried to use folk remedies - wormwood. But the latter is not particularly effective, so I had to buy Neo aerosol. The last one is odorless. After the second treatment it helped, we got rid of the parasites.”

Alina, 40 years old, Ufa. “I also remember the old Soviet dichlorvos, from which even a respirator didn’t really help, but cockroaches and bedbugs disappeared. Modern means are more comfortable for a person in this sense, but at least 2 treatments have to be carried out. For the first time I used Combat, then I decided to change the product so as not to be addictive, and treated my home with Neo. The second drug is more effective. At the same time, it does not have an unpleasant odor.”

If dichlorvos did not help, what should I do?

If you cannot cope with a bedbug infestation on your own, you can seek the help of professionals. The favorite habitat of bedbugs is the bedroom, so the living rooms will be treated first. Experts find places where bedbugs live by following traces of their excrement - small black dots. The more black dots, the more infested. And next to them there may also be bedbug eggs, as well as their skins.

Companies provide a guarantee for bedbug treatment for 1-2 years. When concluding a contract, a mandatory condition is stipulated - the owner of the property must ensure complete sealing of the premises in order to prevent the arrival of bedbugs from neighbors.

If bedbugs appear again during the warranty period, exterminators carry out repeated treatment. The conditions for its implementation must be specified in the contract.

If bedbugs have not appeared in the apartment for a month, it is considered that the disinfection was successful and the apartment is completely cleared of insects.
