“Dichlorvos” for cockroaches: an odorless product, and other differences between the modern aerosol and the Soviet “namesake”

Hardware stores offer a wide range of insecticides in convenient gel, paste, powder, crayons or trap forms. But the good old “Dichlorvos” does not lose its popularity. The product has eight undeniable advantages.

1. Performance. Insects die within a few hours after treating the room.
2. Range of action. “Dichlorvos” has a detrimental effect not only on cockroaches, but also on other domestic insects (flies, mosquitoes, ants, fleas).
3. Attack on three “fronts”. The insecticide affects insects through the respiratory tract, gastrointestinal tract and shell.
4. Easy to use. No need to cook or mix anything. Simply spray the product from a can. This shape makes it easy to handle the most difficult to reach areas.
5. Prolonged effect. The insecticide retains residual activity for up to two weeks, after which it begins to decompose in the air and gradually disappears.
6. Economical. On average, one can is enough to treat 15-20 square meters. m.
7. Practicality. Does not leave stains on furniture, walls and floor coverings.
8. Availability. The aerosol is available at most hardware stores and is relatively inexpensive.

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.

Operating principle

The principle of operation of the product can be described in three points.

1. Breath. Spreading in the air, insecticide particles enter the cockroach's respiratory tract. Next, absorption into the hemolymph and distribution throughout the body occurs.
2. Surface contact. Pyrethroid particles settle on the shell, gradually penetrating the body. Once in the blood, the insecticide has a nerve-paralytic effect.
3. Gastrointestinal tract. The chemicals that make up the aerosol settle on surfaces over which cockroaches run. The insect stains its legs, and when it begins to clean them with its jaws, it eats the poison. As it spreads throughout the body, the substance blocks the activity of the central nervous system.

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.

Features of integrated flea control

Dust powder is one of the most accessible, cheap and easy to use products. But to remove fleas, it is not enough to walk across the floor with a rag soaked in an insecticide solution. In such a situation, an integrated approach is important:

1. Before treatment, thoroughly vacuum the floor, move furniture away, and treat corners and baseboards.
2. It is important to clean all textiles in which fleas could lay eggs. Clothes, bedding, and bedspreads must be washed in hot water using disinfectants.
3. To treat carpets, sofas and other upholstered furniture, it is better to use a steam generator, because... parasites die at high temperatures.
4. Fleas are also sensitive to cold. In winter, you can take carpets and other textiles outside or leave them on the balcony for several hours.

Before treatment, you need to vacuum the floor.

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.

Security measures

During treatment, people and animals must leave the apartment. If you have an aquarium, you need to take it out, this also applies to cages with birds, hamsters, guinea pigs and other pets.

There remains one person who carries out the procedure and always uses protective equipment. Remember that you will be working with a toxic chemical that is dangerous to human health if you do not neglect safety measures. Be sure to use clothing that completely covers the body so that the product does not get on it, including shoes.

The procedure is carried out wearing rubber gloves, a respirator, and safety glasses. Due to the fact that when applied, the substance is sprayed, microparticles of the toxic chemical are in the air and a person who does not use protective equipment will inhale them, in addition, they will get on the skin and mucous membranes, and this should not be allowed.

If during the procedure the drug gets on the skin or mucous membranes, be sure to rinse with plenty of water. If during treatment you feel unwell, nausea, dizziness or other symptoms, you must immediately stop work and go outside.

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.

Advantages and disadvantages

Let us briefly summarize the use of the popular anti-bedbug product “Clean House”.

• high efficiency of insecticide;
• convenient release forms;
• low toxicity;
• low cost.

• Strong smell;
• absolutely safe for bedbug eggs;
• relatively toxic.

The Clean House product is an insecticide that acts on insects, aquarium fish, amphibians and reptiles. Available in two forms: spray and powder. Clean House helps against bedbugs better than other insecticidal preparations due to the combined composition of active ingredients and an additional device in an aerosol can.

Active ingredients in Clean House:

• tetramethrin: paralyzes bedbugs;
• Cypermethrin: affects the central nervous system and internal organs of bloodsuckers.

Both substances belong to the class of pyrethroids and are second-generation synthetic insecticides.

Piperonyl butoxide (10%) has also been added to the powder form of Clean House, which significantly extends the life of the anti-bedbug product.

Bedbug repellent Clean House kills insects in one go, but does not affect their eggs. The latter is the main disadvantage of this product. When removing bedbugs, treatment must be carried out at least twice. And it’s better not to wait for new bites to appear. The advantage of Clean Home is the absence of odor after treatment.

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.

Adviсe

• You can get rid of newly hatched nymphs by boiling bed linen, ironing it and treating it with a steam generator.
• After the baiting of bedbugs is completed, the consequences in the form of nests remain in many places. Many try to remove them physically - by trampling them. The technique is certainly effective, but the best way to get rid of residual effects is to wash floors and other surfaces with a soap-salt solution.
• The incubation period for bedbug eggs is 2 weeks; after this period, re-treatment of the premises must be mandatory. Otherwise, a horde of bedbugs will attack the apartment again.

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.

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.

Rules of application

Using Clean Home Spray

To achieve maximum effect, you must follow the recommendations indicated in the instructions for using the Clean Home Flea Spray.

1. The use of personal protective equipment is one of the main rules for using the spray. It is important to protect not only the respiratory organs from the effects of insecticidal components, but also the mucous membranes and skin. To do this, spray treatment must be carried out wearing rubber gloves, a respirator and the most closed clothing possible.
2. All household members and pets must be removed from the room in which treatment is planned. Aquarium fish and amphibians are no exception.
3. If the kitchen area is to be processed, then food products must be packaged in hermetically sealed containers (bags) or taken out to the balcony. Similar actions should be taken in relation to children's things and toys.
4. The aerosol can is shaken well so that the solution contained in it becomes homogeneous. After which, at a distance of 0.3 m, all surfaces, furniture and favorite habitats of fleas or bedbugs are treated.
5. Windows and doors in the apartment or house being treated must be tightly closed. After 12 hours, the room is thoroughly ventilated, after which it is wet cleaned.
6. If there is an excessive accumulation of fleas or bedbugs, the entire apartment must be treated.

Flea remedy Clean House is easy to find in any hardware store or market in Moscow.

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.

Dust selection criteria

When choosing insecticides, you need to pay attention to the following characteristics:

• composition - if the powder contains substances that attract parasites, then the effect of its use will be more pronounced;
• release form - aerosols are much more dangerous than soap and products for preparing emulsions;
• hazard class – level IV products are considered relatively harmless; if the packaging indicates class III or II, it is better to refuse the purchase;
• cost of the product - more expensive insecticides are not always more effective.

Preparatory stage

Despite the fact that liquid and dry forms of insecticide are used differently (dust is not applied to vertical surfaces), the preparatory stage, regardless of the chosen form, is always the same, consisting of five steps.

1. Cleaning. Before the liquidation operation begins, the apartment must be thoroughly cleaned. The floor should be washed with a damp cloth soaked in clean water, without adding chemicals. The dust needs to be wiped off and the carpets need to be vacuumed.
2. Clearing the premises. It is advisable that all warm-blooded creatures, including household members, leave the apartment. Only the “exterminator” should remain in it. If fish or reptiles live in the house, and it is not possible to remove the terrarium or aquarium, these objects should be covered with something on top.
3. Removal of bed linen. Sheets, pillows, blankets and mattresses must also leave the house. Send them to the balcony or to a bench in the yard. The fabric tends to absorb insecticides that are sprayed or thrown, which then come into contact with your body.
4. Isolation of products. Food should not come into contact with poison. Therefore, at the time of spraying the aerosol or spray, it must either be eaten or sent to the refrigerator.
5. Moving furniture away. Cabinet and upholstered furniture must be moved away from the wall. The back surfaces must be processed. Perhaps a nest of bedbugs has already appeared on one of them, or will appear in the near future if you ignore this requirement.
