How does a flea treatment based on dimethyldichlorovinyl phosphate work in the home?
A powerful insecticide called Dichlorvos leaves no chance of survival for any flea. The drug based on dimethyldichlorovinyl phosphate is considered safe for humans and warm-blooded animals if used according to the instructions, but lethal for insects. There are several varieties of Dichlorvos on sale with the prefixes “Neo”, “Eco”, “Super”, “Varan”, which, compared to the Soviet-era drug, are more effective, but not toxic.
Based on the experience of past generations, it is not for nothing that modern people trust Dichlorvos. The drug, getting on the surface of the flea, paralyzes it and leads to inevitable death. The product helps fight adults and their larvae, but does not pose a danger to the eggs and pupae of the parasite, because the latter are protected by a heavy-duty shell. If you decide to completely eradicate fleas, then the can of Dichlorvos should be re-sprayed a few weeks after the first time to get rid of the grown parasites.

I sprayed the aerosol according to the instructions, followed safety precautions, and went on a business trip for three days. I thought that during this time it had already managed to erode even through the window cracks, but then I did the cleaning, and it was as if the parasites had never been there.

First aid
If dichlorvos gets into your eyes:
- rinse your eyes thoroughly with water, or saline, or a two percent soda solution (1 tsp of soda for 1 cup of water);
- drip Albucid or some other medicine for eye inflammation into the eyes;
- if necessary, apply a blindfold;
- consult an ophthalmologist.
If dichlorvos gets on your skin:
- wash the affected area with water and soap or a two percent soda solution;
- Do not rub the affected skin too hard under any circumstances: this helps the poison penetrate into the deeper layers of the skin;
- remove all clothing that the person was wearing at the time he was infected with dichlorvos, as particles of poison may remain on them.
If a person has inhaled dichlorvos vapor:
- take the person out into the fresh air;
- remove all clothing that the person was wearing at the time he was infected with dichlorvos, as particles of poison may remain on them;
- the victim should rinse his mouth and nose, rinse all exposed parts of the body with water, as dichlorvos molecules may get on them;
- the victim should lie down in bed and calm down.
If dichlorvos gets into the digestive tract:
- give the victim plenty of clean water to drink;
- induce vomiting;
- give any adsorbent drugs;
- one hour or an hour and a half after the sorbent, give a laxative based on salt: magnesia, Glauber’s salt;
- It is also useful to do an enema, but only if the victim himself or someone nearby knows how to do it, otherwise the patient can be further injured;
- again give plenty of clean water or tea, jelly to drink;
- put the patient to bed and provide him with peace.
The victim should eat light natural food for several days and be sure to drink kefir to restore the intestinal microflora.
With a small amount of dichlorvos ingested, you can do without medical help, much less hospitalization. After two or three days the person recovers completely. But if a child who is not even a year old is poisoned, a doctor is definitely needed. In older children, intoxication can also develop very quickly due to their weak immunity, so for the complete safety of children it is better to seek advice from a specialist.
If an allergic person is poisoned, in addition to other measures of assistance, he should be given antiallergic medications as soon as possible. Tavegil or suprastin, antihistamine ointments for the skin are suitable if the chemical gets on it.
Operating principle
The principle of operation of the product can be described in three points.
- Breath. Spreading in the air, insecticide particles enter the cockroach's respiratory tract. Next, absorption into the hemolymph and distribution throughout the body occurs.
- Surface contact. Pyrethroid particles settle on the shell, gradually penetrating the body. Once in the blood, the insecticide has a nerve-paralytic effect.
- 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.
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.
Prevention
How to use dichlorvos to eliminate the risks of poisoning? There are several rules that will help you avoid unpleasant consequences.
- All manipulations with dichlorvos should be carried out only in special clothing and protective equipment (gloves, respirator).
- Both during and after treating the room with dichlorvos, it must be well ventilated.
- Under no circumstances should pregnant women and allergy sufferers manipulate dichlorvos.
- After finishing the treatment of the room, no people or animals should be in it for at least four hours, preferably six hours.
- After finishing the treatment, all working surfaces must be washed or at least wiped thoroughly.
- You should buy dichlorvos only in stores, and not from individuals, who can make it themselves, without taking into account sanitary standards.
- Dichlorvos should be stored out of the reach of children.
- It is best not to carry out any actions at all with dichlorvos, but to leave disinfestation to SES workers.
Nevertheless, the modern formula of dichlorvos is so improved that poisoning with this chemical can only be caused by particularly improper use, either intentionally or by people with very poor health.
