What is dichlorvos and what insects is it effective against?

Pest control – these are any measures aimed at exterminating insects. If an apartment is infested with bedbugs, a characteristic unpleasant odor appears in it, which is absorbed into various materials: upholstered furniture, textiles, carpets, curtains, clothes and other personal items, wallpaper, floor coverings. The use of insecticides adds color to the aromatic picture. Although many manufacturers try to make bedbug chemicals less odorous, caustic, and toxic, this is not always successful. After treating a room for bed bugs, a specific smell remains. It can be very persistent, and sometimes getting rid of the smell is more difficult than getting rid of pests.

The smell after disinfestation remains both after the work of professional exterminators and after using the products yourself. All drugs consist of chemicals that have their own aroma or acquire it in combination with other ingredients. Sometimes manufacturers add a fragrance, which is designed to mask the own unpleasant odor of the drugs.

Cheap bedbug baiting agents usually smell bad and pungent. To reduce the cost of such products, manufacturers do not work on the aromatic component. In addition, products from this price category do not contain the most effective and high-quality active ingredients, which require an increased concentration of the working solution to work. Because of this, their smell is stronger. Many products have been used for several decades, that is, they were developed for a very long time, since then science and production have moved far forward, but these drugs have remained at the same level. They are effective, but, unfortunately, toxic.

Newer insecticidal products smell less. Manufacturers even say about some of them that they are odorless. But their cost is significantly higher. But efficiency does not always have the same correlation.

Attention: under no circumstances should you inhale chemical insecticides or sniff the anti-bedbug product in the bottle, even if it is written on it that it is odorless. You can get a burn to the mouth, larynx, and nasal mucosa. It can also lead to breathing and digestive problems. If you have asthma or breathing problems, inhaling the insecticide can be very dangerous and even fatal.

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.

Getting Rid of Fleas: 5 Steps to Insect Freedom

The difficulty in removing fleas from an apartment is that they multiply very quickly. Treating individual surfaces does not help: pupae remain in other places, which become fleas, bite a person or animal, and you have to start the fight again. Fleas live on the floor, under baseboards, in beds and other objects located at a height of no more than one and a half meters.

Start your room treatment by fighting your pet's fleas. The animal must be washed with a special shampoo, and then treated with a spray and put on an insecticidal collar.

How to get rid of fleas: treating an apartment

1. Wash all bedding and bedspreads at a temperature of 60C and above. Wash your dog bed, cat house or mattress too, and if this is not possible, throw it away.
2. Vacuum carpets and upholstered furniture. Don't forget about all the rugs and rugs that lie on the floor and hang on the walls. Immediately after cleaning, empty the contents of the vacuum cleaner into the toilet or take the tightly tied bag outside before the insects scatter.
3. Wash the floor with water and added wormwood essential oil. Insect eggs will be washed away, and they will not lay new ones on the surface with the smell of wormwood for some time. Particular care should be taken to wash corners, baseboards and the floor under furniture.
4. It is better to throw away all things that cannot be cleaned and washed. If fleas live in an old chair and lay eggs there, it will be a constant source of parasites.
5. Wash all outdoor shoes thoroughly with a sponge and detergent. Then you can be sure that there will be no flea eggs left on your soles.

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.

Aerosol cost

The advantages of Dichlorvos are its affordable price and the opportunity to buy poison for arthropods at the nearest store that sells household chemicals. The comparative table lists the estimated prices for aerosols from different manufacturers (data as of January 2022).

Table - Comparison of prices for "Dichlorvos" against bedbugs

Name	Volume, ml	Cost, rubles
"NEO"	190	150
"Antiklop Varan"	180	145
"Raptor"	225	230
"Clean house"	150	65
"ECO"	190	80

Toxic damage when working with Dichlorvos is extremely rare. The primary symptoms of poisoning are dizziness, nausea, and an unpleasant taste in the mouth. Sometimes these symptoms are accompanied by an allergic skin reaction and seizures.

First aid for a toxic injury is to remove the victim to the open air and wash the affected areas of the skin and mucous membranes under running water. Before the ambulance arrives, the patient is given a sorbent so that the poison leaves the body as quickly as possible.

Some say that Dichlorvos copes with the task perfectly. Others insist that by buying it, they threw money away. Reviews of Dichlorvos for bedbugs will clarify the situation completely and help you understand whether the product will be effective in your case.

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.

How to get rid of odors easier when disinsection

If you order pest control services from a professional sanitary service, discuss this point when ordering. They will select products that smell less and disappear faster.

If you decide to get rid of bedbugs yourself, choose insecticides that:

• effective against resistant insect populations, that is, they will help destroy them in one application and will not require repeated applications in high concentrations;
• made by a manufacturer you can trust and have a good reputation;
• have detailed instructions for use;
• do not have a very pungent odor;
• easy to use.

These are the products that Medilis offers. For example, Superpower spray against bedbugs is effective in combating parasites, but disappears quite quickly and is non-toxic. It is not used, like all other chemical insecticides, to treat bedding or clothing. But it is convenient to spray on any hard surface. The product does not require dilution with water to a working solution; it is produced in easy-to-use packaging - 250 ml bottles with a sprayer. The product is suitable for everyday use by the general public.

If you follow the instructions for use and after wet cleaning and ventilation, there will be no trace of bedbugs left in the apartment, and there will definitely be no unpleasant odors.

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.

Where do fleas come from in the house?

Fleas are very prolific: over 2 years of life, the female lays about 500 eggs, which after 2 weeks begin a full life and active reproduction. Insects need a source of food and a place to lay eggs. Therefore, they strive to penetrate the nest of a wild animal - a rabbit or a squirrel, or into a city apartment. How do they do this?

• a pet brings one or more insects from the street on its fur;
• flea eggs are carried into the apartment on the soles of shoes;
• fleas enter the apartment from neighbors;
• insects from the basement or attic can penetrate into nearby apartments

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.

If there are signs of poisoning????

Symptoms:

• nausea;
• headache and dizziness;

• increased salivation;
• tearfulness.

You need to leave the treated apartment. Symptoms quickly disappear if you spend some time in the fresh air.

You should keep an antihistamine on hand. If the reaction is severe, take this drug.

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.

Historical reference

Dichlorvos

In the mid-20th century, specialists from the German concern Bayer developed an insecticide in the form of a spray. Soviet scientists proposed their development - dimethyl dichlorovinyl phosphate. The packaging was borrowed from the Germans. The drug was named "Dichlorvos".

The question of where to buy dichlorvos did not even arise for Soviet people. The product was sold in all hardware stores throughout the USSR.

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.

Preparation of a solution based on baking soda ????

If you plan to poison bed bugs in this way, you need to follow the instructions for preparing the product:

1. Use 1 liter of water, 150 g of soda. If necessary, the number of components is increased in accordance with the recommended proportions.
2. The soda must be completely dissolved in water.
3. Add 150 ml of kerosene and 100 ml of turpentine.
4. After 1 hour, add liquid soap.

It must be taken into account that the substance will smell even after all the necessary measures have been taken to eliminate the smell: ventilation, cleaning, etc. The smell will gradually be removed. For this reason, the solution should not be used if there are children or allergy sufferers at home.

To reduce the toxicity of the product,

Instead of kerosene and liquid soap, add 30 g of naphthalene.

Soda powder dissolved in water

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.”

Calling the Professionals for Flea Control

If you do not want to start a war with fleas, entrust the removal of uninvited guests from your apartment to mercenary exterminators. Their composure and extensive experience in this matter help to quickly defeat the enemy. The cost of professional flea disinfestation is higher than the cost of a can of insecticidal spray, but the specialist gives a guarantee and completes the work in the shortest possible time.

Call a specialist and tell them whether there are a lot of fleas in the apartment. This is important to choose the right drug and equipment.

Before the exterminator arrives, prepare the apartment for treatment.

• people and pets must leave the apartment during treatment;
• cover the aquarium with glass and turn off the air supply;
• remove bed linen and bedspreads, move furniture away from the walls;
• throw away old items that may contain flea colonies;
• hide food and dishes;
• prepare equipment for cleaning after disinfection.

Application procedure

First of all, dichlorvos can be used against lice, mites (including scabies), fleas, feather eaters and lice eaters only on domestic animals. Ridding a person of external and subcutaneous parasites is a matter of medicine and resp. medications prescribed by a doctor. Dichlorvos is generally not very effective against lice, because Doesn't kill nits. There are known cases where self-medication with universal dichlorvos for lice pubis led to impotence in men, frigidity and infertility in women.

Next, before using dichlorvos, you need to track down the nests of harmful arthropods and their migration routes. This is especially true for bed bugs and other flightless blood-sucking parasites. And even more “special” – bedbugs. Here, correct “calculation” of the enemy is the key to success by 80-90%. If “reconnaissance of the deployment of enemy forces” is carried out correctly, it is possible to kill bedbugs using such simple safe means as citric acid:

The next stage is the preparation of PPE:

1. On the body - work clothes, shoes and a hat that completely cover it;
2. Over clothing - a waterproof cape or work robe for working with chemicals (made of chemically resistant calender synthetic fabric). An acceptable replacement is a polyethylene (not PVC!) or rubber apron from shoulders to ankles;
3. On the face - safety glasses (cheap plastic ones are possible) and a filtering respirator of initial level of protection. The anti-dust “zero” petal respirator is unsuitable;
4. Protective gloves with high cuffs on your hands. You can use household latex, but double-layered (the back is white, the “face” is colored). The edges of the gloves are pulled over the sleeves.

Now – the choice and purchase of the drug. The selection criteria can be developed based on what you read above, and the volume of the cylinder(s) is determined by the average specific flow rate. For quality products it is approx. 2-3 ml per 1 sq. m of room area. If the ceiling is higher than 3 m, the flow rate increases to 3-4 ml/sq. m. The same thing for exterminating bedbugs. From them in high rooms - up to 6-8 ml/sq. m.

When everything is ready for processing, the inhabitants are removed. People are being moved to pre-arranged temporary premises. It is advisable for them to take less personal belongings with them, because... they may contain eggs and fertile insects. Animals are placed with friends or in a shelter. The latter is preferable: the pets will be provided with qualified care, and a veterinary examination upon admission will reveal possible pathologies. They say that 3 crossings are equal to one fire. If the house contains an aquarium, then 1 = 1 + a decent explosion or earthquake: the tank will have to be completely emptied, and at least 3 weeks after treatment, it will have to be started and populated from scratch.

To continue the work, it is advisable to find a trained observer assistant, also wearing PPE. The observer is located outside the room (preferably on a balcony, veranda, etc.), constantly through a window (better) or periodically entering, monitors the progress of work, the condition of the operator, and, if necessary, provides him with first aid and/or replaces him. The actual processing is carried out as follows:

• A week before treatment, the operator and observer should not drink alcohol or take neuroregulatory or psychotropic drugs. It is highly advisable for smokers to abstain from their favorite potion. At the same time, it is necessary to avoid scandals, nervous breakdowns, and hysterics (including quiet ones). The presence in the body of traces of any substances that affect the state of the nervous system (including “self-prepared”) sharply increases the likelihood and severity of poisoning. The author personally observed a case when an exterminator on call suddenly fell dead and left the hospital disabled. It turned out that he was a newbie, had not been properly checked, and had smoked “weed” about 3 days before;
• The trash can is emptied and washed; the bag is not put into it. Food products, dishes and cutlery are moved to a safe place. The refrigerator is emptied, defrosted, tightly closed, unplugged and covered with film. Crumbs and grains are carefully removed from the kitchen furniture, cleaned of fat and other traces of food products;
• Indoor plants can be left in place - the pyrethroids of universal dichlorvos are not phytotoxic;
• A general wet cleaning of the room is carried out - with moving furniture, removing carpets and soft floor coverings, shaking up books, etc. Remember: drug residues in the dirt and dust for a long time later can cause invisible but insidious micro-poisoning of the inhabitants of the house!
• Clothes and other soft items are removed from cabinets, chests of drawers, cabinets, hung and laid out in the room;
• Doors and windows close tightly. The assistant controller leaves the premises for the post;
• The aerosol canister is shaken vigorously at least 5-6 times before spraying;
• First of all, the identified nests of insects are sprayed, then along the routes of their migration they are treated to feeding stations (bed, trash can, etc.). This costs approx. 1/2 the volume of the drug. Still ok. 1/3 is sprayed on soft items, and the rest is used on furniture, carpets, rugs, etc. In all cases, spraying is carried out from a distance of 20-30 cm, so that “fog” settles on the objects being treated rather than splashes;
• If the drug gets on clothing, remove it immediately and set aside for washing. If it penetrates the body, wipe the affected area with a swab soaked in a 1-2 tbsp solution of baking soda. l. per 0.5 liters of water and washed with water. If there is no deterioration in health, change clothes and continue working;
• If you get it in your eyes, or there is pain in them, or they become watery, rinse your eyes open under running water. If it hasn’t passed within 10-15 minutes, they stop working and contact an ophthalmologist. Feel better - they take the place of the observer, and he takes on the functions of the operator. In this scenario, you can (and should) consult a doctor after finishing work;
• In case of contact with mucous membranes, or in case of any deterioration in health, immediately stop working, cleanse the stomach with “folk” remedies, take 2-3 tablets or activated carbon powder with a glass of water and consult a toxicologist;
• At the end of the treatment, leave the room tightly closed and leave it for at least 6-24 hours (according to the instructions for the drug);
• At the end of the exposure time, ventilate the room for at least 6 hours (again, according to the instructions for the drug);
• After treatment against bedbugs for the return of the inhabitants, for 1-3 weeks they carefully look for signs of the presence of surviving parasites: traces of bites, smell, the presence of individuals in secluded corners. Repeated treatment, if necessary, is carried out no earlier than after 7 days. It is not worth leaving the room uninhabited for this time: the new generation of parasites that have emerged from the eggs can go into hibernation for a long time, and letting a newly inhabited room be destroyed is much more troublesome than a just treated one.
