Dichlorvos: composition, properties, instructions for use

Composition and properties

Many people remember Dichlorvos as it was in Soviet times, but this version has long ceased to be produced. The fact is that the drug contained dimethyldichlorovinyl phosphate, which effectively destroyed colonies of parasites, even the largest of them. The chemical compound had a negative effect not only on pests, but also on humans: it caused serious poisoning and a general deterioration in health. Therefore, the chemical was forced out of the market.

With the development of technology, manufacturers have been able to create the safest drugs that fight insects well without having a negative effect on humans.

Currently, the composition of Dichlorvos has changed greatly. Each manufacturer makes a unique set of components, but all such insecticides contain the following chemicals:

• cypermethrin;
• tetramethrin;
• permethrin;
• piperonyl butoxide.

Cypermethrin is a popular insecticide of contact action, that is, to obtain an effect it must get onto the chitinous cover and into the respiratory tract.

The active formula blocks the nervous system of cockroaches, bedbugs, ants, flies, fleas, disrupting the transmission of nerve impulses and thus paralyzing the pests. Unable to move, search for food, or breathe, the parasites die.

Also, third-party components that do not affect the effectiveness are added to the drug:

• fragrances;
• ethanol;
• preservatives;
• stabilizers.

Dichlorvos acts for a week and then disappears. It is necessary to carry out repeated treatment if the population is large. But the effect is noticeable almost immediately: already on the second day after spraying.

The chemical is available in the form of sprays with a volume of 10 to 30 ml, in canisters up to 10 liters. The convenient shape allows you to kill insects yourself.

There is no exact answer to the question of whether Dichlorvos is harmful to humans. If used correctly and if you are not allergic to the components, the chemical will be safe.

However, if you violate the rules of use, you can become poisoned with Dichlorvos and get unpleasant symptoms.

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.

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:

1. Close all windows and doors in the room.
2. Shake the can well.
3. 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.
4. After complete treatment (corners, baseboards, floors, ventilation grilles, cabinets, door jambs), leave the room for 3-4 hours.
5. When the smell dissipates a little, wipe all surfaces with a damp cloth - this will remove the “aroma” of the poison.
6. Mix 50 g of grated laundry soap, 50 g of baking soda, 5 liters of water.
7. Wipe the surfaces that the apartment residents come into contact with with a cloth soaked in the resulting solution.
8. 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:

1. Place textiles in a sealed bag.
2. Spray Dichlorvos inside; it is better to choose an odorless product.
3. Close the package.
4. Leave for 3-4 hours.
5. After treatment, wash bed linen and clothes at the maximum permissible temperature, boil if possible.
6. 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 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.

Insect control

Dichlorvos is a universal drug that acts on different types of insects. But for each you need to choose your own approach: this is how the treatment of the room will be most effective.

Bedbugs

Bedbugs are blood-sucking parasites; the poison cannot enter their body with food. Dichlorvos will work if you spray all surfaces with which uninvited guests come into contact. It is also necessary to find nests - this will help destroy most of the uninvited guests. Typically, bedbugs live in sofas, beds, armchairs and other upholstered furniture, mattresses, bed linen, old furniture, and books.

To get rid of bedbugs using Dichlorvos, you need to:

1. Free up hard-to-reach places.
2. Find nests.
3. Spray them at a distance of about 25 cm.
4. Repeat treatment after 7-14 days.

The chemical is also effective in the fight against bed bugs. To withdraw them, follow these instructions:

1. Remove bed linen.
2. Wash it at high temperatures, treat it with an insecticide, wash it again.
3. Remove the mattress.
4. Find a nest of bed bugs.
5. Spray it with spray.
6. Treat the sleeping area.
7. Leave for 3-4 hours.
8. Ventilate the room.
9. Wipe furniture and floors with a damp cloth soaked in a solution of 0.5 pieces of laundry soap and 1 liter of water.
10. After 1.5 -2 weeks, re-treat.

Advice! During the treatment period, it is better to sleep in a different place.

Before poisoning bedbugs, warn your neighbors about this if you live in an apartment building. Uninvited guests may run to nearby apartments to escape the poison. It is best if neighbors begin to remove parasites at the same time and take preventive measures.

Cockroaches, ants

The effect of Dichlorvos on cockroaches is not so effective; it is best to combine the aerosol with other means, for example, traps.

Insects die when they come into contact with the insecticide. It is necessary to treat all surfaces where they have been. Most often, cockroaches live in the kitchen, in which case you need to act very carefully: you must not allow the poison to get into your food or dishes. Use an odorless chemical to prevent it from becoming embedded in your kitchen furniture.

Dichlorvos against cockroaches will help if you follow the instructions:

1. Deprive pests of access to water - cockroaches will not live long without liquid.
2. Remove all dishes, or at least cover them with plastic wrap.
3. Remove food from the kitchen.
4. Clear all hard-to-reach places.
5. Spray all cracks, baseboards, corners, cabinets, shelves.
6. Treat floors and walls.
7. Close the room, leave it.
8. After 1.5-2 hours, ventilate the kitchen.
9. Carry out wet cleaning with a solution of 0.5 bars of laundry soap and 1 liter of water.
10. Repeat the procedure for removing cockroaches after 2-3 weeks.

The principle of operation of Dichlorvos against ants is similar: you need to spray the aerosol in the room where insects were seen most often.

However, there are some nuances here:

• To effectively get rid of an ant colony, you need to find the nest where the queen lives. There may be several such places. The chemical is sprayed over the nest at a distance of 20-30 cm;
• Foraging ants usually remember the path from the nest to the food source and always use it. By observing the habits of insects, you can find their habitat.

Attention! As with bedbugs, warn your neighbors before poisoning cockroaches and ants. These insects can also move into neighboring apartments.

Fleas

Dichlorvos against fleas helps when all their habitats have been thoroughly treated. Pests usually hide in pet bedding, on carpets, rugs, and behind baseboards. To get rid of fleas, you need to spray the product on these objects, walls, furniture up to 1 m high. These pests can jump high, so if you miss a section of the wall or habitat, the fleas will return very soon.

Do not spray the chemical near food bowls. Bedding and blankets must be washed well at high temperature 1-2 weeks after flea removal. Before washing, pets should not be allowed on them; people should also limit contact with treated items.

Attention! To completely destroy fleas, you need not only to treat the surfaces, but also to remove pests from the animal’s fur. Use special drops, a collar, and shampoo.

Flies, mosquitoes, wasps

Dichlorvos helps against the invasion of wasps, mosquitoes, flies, and midges in the apartment. To get rid of flying individuals, follow these recommendations:

1. Apply the product to the areas where most pests are usually found.
2. Spray the product around the apartment.
3. Leave for 3-4 hours, during which time residents should not be at home.
4. Ventilate all rooms.
5. After 30-60 minutes, carry out wet cleaning.

Repeat this procedure after 6-7 days to ensure that flies, midges and wasps are removed.

Attention! To get rid of mosquitoes, it is more convenient to use safer means, for example, fumigators. They act just as effectively, but cause much less harm to health.

Mole

To get rid of moths using Dichlorvos, you need to:

1. Remove all clothes and shoes from the closet.
2. Take fur and fur coats out onto the balcony or street.
3. Spray the chemical inside.
4. Leave the cabinet closed for 2-3 hours.
5. Spray a large fabric or clothing cover with the aerosol.
6. Cover fur items with this material so that they absorb the smell.
7. Open the cabinet doors and leave the windows in the room open to ventilate the furniture a little.
8. Wipe the shelves with cleaning liquid.
9. Repeat treatment after 3-4 weeks.

In addition, the product is used as a prophylaxis. Before storing wool or fur, wrap it in paper sprayed with poison.

The insecticide is allowed to be used only for clothes and textile moths. It is highly undesirable to use it on kitchen cabinets and shelves, as the product remaining on them will poison food. Floors and baseboards can be sprayed, but before doing this, you must remove all food from the room and use the room less often for 2 weeks after spraying.

Attention! To protect your cabinets from moths, place bags of dried lavender and dried citrus slices on the shelves.

Lice

Dichlorvos also helps get rid of body lice. It effectively kills adults, but is completely harmless to nits - parasite eggs have a special protective shell, so the treatment must be repeated 2-3 times every 2-3 weeks.

You can remove body lice with Dichlorvos as follows:

1. Place contaminated items in large plastic bags.
2. Spray an aerosol inside them.
3. Leave for 1-2 hours.
4. Wash on high temperature.
5. Iron at the maximum permissible setting.

It will not be possible to remove lice on the head with Dichlorvos, since the chemical is very toxic, causes skin irritation, peeling, and often leads to hair loss. There are more convenient and safer remedies for head lice.

Other insects

The insecticide also helps get rid of other annoying insects, both in the house and in the garden.

For example, Dichlorvos is used to remove spider mites from indoor plants. Instructions for use are as follows:

1. Cover the plant with a cardboard cone or plastic bag.
2. Make a small hole in it.
3. Spray the flower with insecticide.
4. Leave for 5-7 minutes.
5. Remove the cap and bag.
6. Repeat treatment after 6-8 days.

Attention! If possible, use another product, as the drug is harmful to plants and soil.

Dichlorvos will help remove spiders and double-wort, but the former are not so susceptible to the chemical. Follow this procedure:

1. Spray the poison in all hard-to-reach places, especially damp and warm ones.
2. Treat areas where traces of two-wort or cobwebs were noticed.
3. Leave the apartment for 2-4 hours.
4. Ventilate the rooms.
5. Wipe floors and walls with a damp cloth.

Another way to use Dichlorvos is to kill aphids on roses. It is necessary to treat flowers according to the instructions, just like indoor plants when spider mites appear. In this case, there is no need to cover the plant with a cone, because the processing takes place in the fresh air.

Again, the chemical is quite aggressive, it is better to use less toxic products.

Ants from the garden are also removed with Dichlorvos. To do this, spray the product over the anthill and around it.

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.

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.

Advantages

Organophosphorus compounds appeared on the insecticide market several decades ago. They are gradually being replaced by new drugs with an improved formula, high efficiency, but less toxicity. But people cannot yet completely abandon the use of this group of insecticides: solutions and aerosols quickly and efficiently destroy parasites and pests of almost all categories.

Pros:

• the universal composition has a detrimental effect on many flying and crawling insects;
• the drug is effective for destroying secretly living pests;
• high insecticidal activity has been confirmed by professional exterminators and millions of owners who have used the product to combat cockroaches, ticks, flies, moths, bedbugs, and fleas;
• the complex effect ensures 100% disinfestation results;
• the presence of three active ingredients reduces the likelihood of resistance: Dichlorvos acts even on pests and parasites that have adapted to the influence of weaker insecticides;
• prolonged action - active components are effective for two weeks after treatment;
• minimal aerosol consumption guarantees high performance;
• after treatment, the drug residues quickly decompose into compounds that are safe for people and pets;
• low price. Dichlorvos Neo belongs to the insecticides of the low price segment. The combination with a small consumption of the drug for treating a medium-sized apartment ensures the minimum cost of disinfestation at home.

Advantages and disadvantages

Dichlorvos has both advantages and disadvantages.

Among the advantages are:

• fast, complex impact;
• Ease of use;
• relative safety for humans;
• the presence of biodegradable components that do not generate toxic waste after use;
• versatility;
• duration of action.

The drug has the following disadvantages:

• the need to process the room several times to achieve results;
• the likelihood of allergic reactions: itching, redness of the skin;
• acrid odor;
• remains on surfaces for a long time, which is especially bad if there is a small child or pets in the house;
• harm to humans after prolonged contact with the drug.

conclusions

Disinfectors often encounter biological resistance of pests. In case of “irritability”, it is necessary to carry out complete disinsection of the building, and if there is a suspicion of resistance, then treat more than once, alternating drugs according to certain schemes.

Do you want to destroy cockroaches so that you immediately forget about the problem? Avoid aerosol products. Instead, use emulsion concentrates (according to the instructions). And remember that eliminating the outbreak locally is easier and cheaper than when cockroaches are everywhere and you need to carry out a complete pest control of the building.

Dichlorvos poisoning

Despite the fact that the modern version of the drug does not contain highly toxic, poisonous substances, you can still be poisoned by Dichlorvos. In addition, allergies often occur after its use.

There are several reasons for the appearance of negative reactions in the body:

• penetration of the chemical into the respiratory tract and mucous membranes;
• entry into the digestive tract.

In case of Dichlorvos poisoning, you must immediately call a doctor and provide first aid.

Symptoms

There are several signs of Dichlorvos poisoning:

• dizziness;
• nausea;
• vomit;
• diarrhea;
• intoxication;
• skin itching;
• cough;
• sudden change in pressure;
• lack of coordination;
• temperature increase;
• headache;
• swelling of the eyelids, conjunctivitis if it gets into the eyes;
• cramps, spasms;
• loss of consciousness.

Typically, symptoms of Dichlorvos intoxication disappear after 2-3 days. But if a person suffering from allergies inhales the chemical, complications may begin.

Treatment

After the ambulance is called, you need to provide first aid to the poisoned person.

In case of intoxication, you must do the following:

1. Get out into the fresh air.
2. Rinse the damaged areas with cold clean water if the drug comes into contact with the skin, mucous membranes, or eyes.
3. Remove clothing and protective elements in which the room was treated.
4. Induce vomiting.
5. Drink plenty of fluids.
6. Take 10 tablets of activated carbon.
7. Take an allergy medicine if you have reactions to any of the ingredients.

Security measures

Although modern types of Dichlorvos are not as harmful as their predecessors, it is still worth learning some precautions before contacting chemicals and strictly following them:

• before carrying out the treatment, you should dress in clothes without any open areas, wear thick rubber gloves, goggles and a respirator or cotton-gauze bandage;
• all items with which households and animals have direct contact, and food products must be removed as far as possible from toxic substances;
• the room must be completely enclosed.

Important: if you suddenly feel a deterioration in your health, signs of poisoning or an allergic reaction (sore throat, dizziness, unpleasant taste on the tongue, etc.), immediately go out into the fresh air.

By following all the above safety measures, you will reduce the risk of poisoning with an insecticide to a minimum. So don’t neglect them and take care of your health and the well-being of those around you.

Chemical basis

Successors of the “real” DDVF for household use are created on the basis of pyrethroids - insecticidal agents first isolated from the plant Tanacetum (Pyrethrum) parthenium (tansy (pyrethrum maiden) or Dalmatian chamomile), see Fig. on right. Its insecticidal properties have been known since ancient times; In addition, pyrethrum is the ancestor of many varieties of garden “Persian” daisies.

Note: why - girlish? In ancient times, an aqueous extract of pyrethrum was used to terminate an unwanted pregnancy. But don’t skimp on abortions in this way if you really can’t give birth. Ingestion of pyrethrum infusion causes severe poisoning, after which incurable disorders of women's and general health are very likely. The “knocked-out” girls of antiquity had nowhere to go - in those days, in many countries, a girl of marriageable age who did not preserve her virginity before marriage faced a slow, painful death penalty. But a husband can forgive or reconcile if he is not the reason for it; Pyrethrum was introduced into use by nuns - a nun who gave birth was supposed to be walled up in the wall of the monastery alive along with the baby.

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.

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.

Consequences

Dichlorvos is characterized by the fact that its exposure causes both immediate consequences (complications) and long-term consequences.

Complications appear within two weeks from the moment the substance enters the human blood. The patient begins to suffer from:

• toxic hepatitis;
• nephropathy;
• pneumonia;
• dystrophy of the heart muscle.

Long-term consequences appear within three years from the moment the substance enters the human blood. The patient begins to suffer from:

• astheno-vegetative syndrome : disturbances in the functioning of internal organs due to poor functioning of the autonomic system;
• myeloradiculitis : simultaneous inflammation of the human spinal cord and spinal roots;
• polyneuritis : diseases of the peripheral nervous system.

For pregnant women, dichlorvos poisoning is doubly dangerous. If it occurs during an early period, the fetus may freeze. If during the last months, the fetus may develop developmental abnormalities or even the death of the unborn child.

Treatment in hospital

The need for hospitalization is determined by the emergency doctor or hospital where the victim went. If there is such a need, the patient will be prescribed such treatment methods.

• Gastric lavage using a tube.
• In case of seizures, medications for them.
• Antidote – atropine sulfate or alox.
• Medicines for the heart, since it is under excessive stress from the poison.
• Antibacterial agents to prevent secondary infection.
• If breathing is impaired - artificial ventilation.

Operating principle

Dichlorvos is effective against bedbugs due to the chemical composition of the spray. Modern insecticides contain pyrethroid substances that block the nervous system of bloodsuckers.

Exterminators know how the aerosol works. Experts note that dichlorvos disrupts the functioning of the organs and systems of bedbugs. This causes the death of the parasites.

Modern aerosols have a complex effect. In addition to affecting the nervous system, the components of the products upset the functioning of the respiratory and digestive systems. Chemical components enter the bodies of bedbugs when insects interact with the places where the spray was sprayed.

Dichlorvos is a potent remedy that retains its effect for more than six months. After all, pyrethroids are unique poisons that have a powerful nerve-paralytic effect.

Where are insects comfortable and what is their danger?

Uninvited guests can appear in any apartment or house, but they linger where favorable conditions exist for them.

Flies are comfortable where:

• cleaning is rarely done;
• accumulate household waste;
• there is access to food and drinks.

Insects can also take a liking to your apartment if they have long and firmly established themselves with unscrupulous neighbors or if the exit to the garbage disposal is located in your kitchen. In a private home, factors influencing the accumulation of pests are the proximity of utility rooms, barns (for example, pigsties or cowsheds, where animal waste products are constantly present) or a cesspool.

You should get rid of insects primarily because on their legs and abdomens they can carry dangerous bacteria that are the causative agents of diseases such as typhoid fever, cholera, dysentery and many others. Pests can deposit larvae in food products, the consumption of which can subsequently cause intestinal disorders in humans. And, of course, flies and midges will not decorate any room with their presence. They cause irritation, bother pets, and disturb sleep with their buzzing.

Adults lay larvae in food, after which it is dangerous to eat them

Insects are very tenacious, reproduce quickly and are even capable of developing resistance to poisons, which is passed on to their offspring. You need to start destroying them without wasting time. Next, we will consider ways to combat flying insects.
