02/21/2018 Category: Bedbugs Author: Irina Litvinova

Grandparents often leave us as a legacy good warm blankets, down pillows, old soft mattresses, beautiful carpets; We have kept some soft toys since childhood - they are very beautiful, even though they are already old. All these household items, unfortunately, often become homes for small bugs. They are attracted by dust and keratinized particles of the human body, which accumulate in all these “dust collectors,” as housewives often call them. These are bed bugs that feed not only on the dead skin of a person or animal, but also on their blood. These parasites are distinguished by their adaptation to various poisons, from which they died some time ago. Many drugs are no longer effective in fighting bed bugs, but Karbofos is still among the most effective insect repellents.

"Karbofos" is a multi-purpose organophosphorus pesticide. The material includes the purpose, composition, formulation, principle of action, safety issues, analogues, etc.

Composition, properties and formulation

“Karbofos” contains the main active ingredient MALTHION with a dosage of 10-50%, surfactant, fragrance - flavoring, filler. To eliminate cases of accidental poisoning, strong flavorings with a pungent odor are used.

Available in the following forms:

- water-soluble powder (packed in small bags of 30g and 60g and large bags weighing 1kg, 5kg);

— suspension — concentrate (ampoules 5 ml, 10 ml, bottles 0.25 l., 0.5 l., 1 l.);

— ready-to-use working solution (5 liter canisters).

Possible harm to humans

Karbofos is a moderately dangerous drug: if the instructions are strictly followed, it is absolutely harmless to human life and health. However, in case of gross violations of safety precautions when handling the drug and non-compliance with safety precautions, there is a possibility of poisoning or damage to the skin by working solutions. The insecticide can also cause allergic reactions if a person has an individual intolerance to the active substance or its accompanying components.

Application and principle of operation

The drug "Karbofos" is an insecticide with an intestinal contact principle of action. Based on insect poisoning when the drug enters the digestive system or onto the surface of the body or part of it. Complete death of the insect is guaranteed after 3-4 hours.

Long-term use of the drug is addictive and significantly reduces the effectiveness of its use. The insect's body produces a special enzyme that destroys the chemical structure of the active substance and neutralizes its effects. It is not recommended to use the drug more than 2-3 times a year.

Receipt

The main method for obtaining malathion is the reaction of addition of dimethyldithiophosphoric acid to maleic acid ester (according to Melnikov, 1987).

The reaction proceeds easily in the presence of basic catalysts in organic solvents or without them. When synthesizing malathion, it is possible to combine the reaction of producing dimethyldithiophosphoric acid with its addition to diethyl maleate, if the process is carried out in diethyl maleate. However, such a combined reaction sometimes proceeds so violently that spontaneous decomposition of the reaction products is possible.

Technical malathion, prepared from purified dimethyldithiophosphoric acid, is quite pure and contains no more than 4% impurities. From crude dimethyldithiophosphoric acid, a drug is obtained with an admixture of trimethyldithiophosphate, which increases its toxicity to mammals.

Malathion can be purified from impurities by distilling off trimethyl dithiophosphate with live steam, as well as by treating with various peroxides.[3]

Preparation and processing

When using either a water-soluble powder or a liquid concentrate, dissolve Karbofos in the required amount of water and mix thoroughly. Apply the drug to habitats, accumulations or movement with a brush or using a sprayer.

Protection against garden pests

When protecting against garden ants, a liquid solution of “Karbofos” (dosage 30g per 3-5 liters of water) is sprayed on anthills and tree trunks, and the powder is also scattered in their habitats, clusters and along paths. The number of treatments is no more than two.

When processing fruit, berry and vegetable crops, the method of spraying or irrigation is more often used. Treatment should also be carried out 2 times, with an interval of at least 3-4 weeks (the first - in early spring before the buds appear, the second - after flowering).

The table shows the purpose, dosage and application rates for the protection of horticultural crops:

Protection from domestic insects - pests

To destroy ants, cockroaches, bedbugs and other crawling insects, a liquid working solution is prepared at the rate of 30g. powder for 5 l. water or 2-4 ml. concentrate for 1-1.5 l. The consumption rate of the working solution is 5 l./100 sq.m. The article “Seven recommendations on how to get rid of cockroaches ” outlines the basic principles of carrying out treatments.

What is Karbofos

Liquid Karbofos is available on sale, in granules, powders and even tablets. The approximate cost of the drug in volumes of 30, 60, 1000 g is 30–200 rubles. The product from the group of insecticides has an oily consistency, characterized by transparency, a specific odor, which evaporates after a while.

When Karbofos is diluted in water, a homogeneous suspension is obtained, suitable for spraying garden crops. In conditions with negative temperatures, the working solution thickens, but retains its qualities. Keep in mind that it is a highly toxic insecticide, and differs from its analogues in the short duration of action of the main substance: after 2 weeks, malathion disintegrates and becomes ineffective.

Using karbofos
Pests are destroyed almost instantly. Features of the concentrate:

1. Karbofos is an insecticide, acaricide of contact action. The effect is noticeable in cases of direct contact with the pest.
2. The product protects those parts of plants with which it comes into contact. The main advantage of this action is the instant elimination of pests.
3. It has a short-term effect. The main substance quickly disintegrates under the influence of sun, water, air. Complete destruction on the street occurs after 10 days, in a greenhouse - after a week.
4. Characterized by continuous action. At the same time it destroys different types of pests and larvae. The downside of this effect is that with constant use, resistance (addiction) forms and the solution becomes less effective.

Reviews

On the Internet, we have collected a number of reviews from people who used Karbofos to combat bedbugs in their homes.

Dmitriy. I bought this product specifically for removing bedbugs, having read a bunch of reviews that it really helps. Opening the bag, I smelled an incredibly nasty smell, like a sewer. Then I diluted the bag into a liter of water and sprayed all the furniture, baseboards and joints. I did not follow safety precautions and decided to limit myself to one respirator. I did this in the morning, before going to work. After the treatment, I was at home for about an hour and had no idea that anything could happen. At work, I began to feel extremely nauseous, and there was an unpleasant bitterness in my mouth. However, by the end of the working day everything went away. Upon returning home, I felt that the smell had noticeably decreased, and I decided to ventilate the room for 20 minutes. In general, after six months, there is no smell in the room, although the furniture still stinks. I suspect that this will never be erased. In short, Karbofos kills bedbugs in a matter of minutes, leaving them no chance of survival. After treatment, I didn’t clean the floors for about a month so that it would be more effective. For six months I did not observe a single bug in my home.

Anna Kryuchkova. I have lived all my life in the countryside and have tried many insect repellents. The oldest, most reliable and effective remedy is Karbofos, which is also sold in liquid form. Liquid is more convenient. The smell, of course, is terrible and slightly harmful to humans. Especially if you decide to use it indoors. But this is the only way to drive away insects like bedbugs and cockroaches. Those that already live with you die instantly, and new ones do not come - because the smell remains and becomes unbearable for them. I recommend it to summer residents and gardeners.

Daniel. An extremely powerful thing. We got bedbugs from our neighbors, tried a bunch of remedies, but only after using Karbofos did these bastards leave us behind. But the thing is extremely smelly. If you can stand it, I recommend it. If not, it is better to look for an alternative remedy.
