Operating principle
The insecticidal-acaricidal drug acts by contact-intestinal route. It penetrates into the body of domestic cockroaches through the chitinous cover and respiratory organs. Karbofos disrupts the functions of the central nervous system. A few minutes after contact with the poison, muscle paralysis and death occur.
The maximum effect lasts 4 hours. During this time, sexually mature and immature individuals die. The eggs in the ooteca continue to develop, but after the larvae hatch, they also die. Karbofos retains toxic properties indoors for up to 4 weeks.
On a note!
If the apartment is heavily infested, it is recommended to carry out repeated disinsection after 14 days to increase the concentration of the drug.
Karbofos is resistant to temperature and light, and is neutralized gradually. An acidic and alkaline environment can eliminate poison. When performing wet cleaning, add vinegar or soap or baking soda to the water.
Mechanism of action
The drug has a complex effect, which allows you to achieve maximum results. After treatment, the substance acts through the respiratory system; in addition, when in contact with the drug, the cockroach becomes infected with poison, which penetrates the chitinous shell. The active substances act directly on the nervous system, the insect is paralyzed and then it dies.
After the surfaces are treated, the maximum activity of the drug occurs within 4 hours. Then it begins to gradually decrease, but the toxic properties persist for 4 weeks. Adults and larvae die first, the eggs remain untouched. But thanks to the long action, all the emerging young individuals also die.
External factors such as light and temperature do not reduce activity. In order to neutralize the effect of the poison, it is necessary to use alkali in the form of soap solutions, or acid in the form of a solution with vinegar. If the apartment is heavily infested, then to achieve maximum results it is recommended to repeat the procedure after about 2 weeks.

The consumption of the product varies, because the parasites are also not the same.

Compound
The active component of Karbofos against cockroaches is the insecto-acaricidal substance malathion. Belongs to the third class of danger. If used incorrectly, it can cause intoxication of varying degrees of intensity, poisoning, and skin irritation. Deadly for bees, amphibians and fish.
Work should be carried out wearing rubber gloves, a respirator, and a suit. There should be no other people or animals in the room. When the first signs of poisoning appear - weakness, nausea, dizziness, stop pest control, provide access to fresh air, rinse your mouth with soda solution, drink sorbent.
Terms of use
The instructions for using Karbofos provide for full or selective disinfestation. Treat rooms where cockroaches have been spotted or where pests are most concentrated. If the apartment is heavily infested, a full treatment should be carried out.
Preparatory procedures:
- move furniture away from the walls;
- carry out wet cleaning;
- hide dishes, food;
- wear personal protective equipment.
The solution is poured into a spray bottle or household spray bottle. Treat the surface from a distance of 20 cm. Be sure to spray baseboards, floors, the back of furniture, areas around trash cans, sinks, toilets, trash cans, pipelines, and ventilation grilles.
Important!
Leave the room closed for at least 4 hours, then ventilate thoroughly. Wet cleaning with a soap and soda solution is carried out in places where hands can touch. The poison remains active in the rest of the room. If necessary, disinfestation is repeated after 2 weeks. Selective application of Karbofos or a less concentrated solution is allowed.
Is it possible to use insecticide against cockroaches and mosquitoes?
Karbofos is productive for killing mosquitoes and cockroaches. To carry out the procedure, it is important to use a spray bottle so that the substance can reach even the most inaccessible places, especially behind baseboards and furniture.
When processing, safety and caution play a significant role. It is necessary to use protective equipment: wear closed clothing so that the substance does not come into contact with the skin.
After the procedure is completed, these clothes will be thrown away; you should think about this in advance. Wear protective goggles and a mask over the eyes to protect the face from allergies and avoid intoxication.
At the very end of the manipulation, you should wash your hands with soap and water and ventilate the room after four hours until the smell goes away. Wet cleaning of the room is carried out later; soap and other chemicals kill the effect of the insecticide completely.
This product should not be used for a long time, as cockroaches have the ability to adapt to chemicals.

Reviews
Reviews about Karbofos boil down to the fact that the drug removes cockroaches, but buyers are not satisfied with the unpleasant odor and toxicity of the solution.
We bought an apartment at a reduced price, but the sellers immediately warned that there were cockroaches in it. They poisoned the Prussians several times, but they appear periodically. We bought it and started looking for an effective remedy. We decided on Karbofos. We carried out a complete disinfection of the entire apartment. After 2 weeks the procedure was repeated. A month later they did a general cleaning; no live insects were seen. We live for six months without being bothered by insects.

We poisoned cockroaches several times with different cockroach repellents. The effect was temporary. Specialists were called. Disinsection was carried out with Karbofos. The smell was terrible even after airing, but the insects disappeared completely within 2 weeks. If we have to deal with cockroaches again, we will immediately buy Karbofos. Helps very quickly.

Karbofos for cockroaches: reviews
I treated my grandmother's apartment - I sprayed it on the wallpaper, walls, behind cabinets, paintings. He grabbed the ventilation and stuffed it with cotton wool soaked in the solution. I used a spray bottle. If you take the matter seriously, the cockroaches will go away. I don't see them at home anymore.
Matvey, Surgut
Only Karbofos helps against cockroaches. My wife and I returned from vacation and found insects in the kitchen. 100% came from neighbors. We processed everything we have. It stinks, it's terrible. But we didn’t see any more creepy crawlies.
Vladislav, Bezenchuk
I began to notice that my little child was watching something on the floor. I looked closer - a cockroach. I bought Karbofos and sprayed it around the apartment. We left. We returned - there were no cockroaches.

Analogs from other manufacturers
Malathion was obtained in the 19th century. The active use of insecto-acaricidal substances in the fight against insects began in the last century. Many professional preparations of domestic and import production are produced on the basis of malathion. You can replace karbofos with the following means:
- Cucaracha;
- Fufanon-Super;
- Medilis-Malathion;
- Doublet K.E.;
- Insecto-Esta;
- Atalnt.
The price depends on the capacity of the bottle. For 1 liter the average cost of similar products is 1300 rubles.
Karbofos is one of the best drugs for cockroaches. It acts instantly and also provides long-term protection against re-infection. Application requires special care, so you need to buy not only an insecticide, but also gloves, a respirator, and choose a long-sleeved jacket and trousers.
Conclusion
In the West, malathion is considered an outdated insecticide. But the reason is the same as for many other, in principle, fairly safe pesticides: excessive and unreasonable use. The consequences are the formation of genetically stable populations of objects of elimination, the accumulation and manifestation of long-term after-effects for people and the environment. With strict, meaningful compliance with the regulations for use, malathion preparations are still quite effective against pests in the garden and vegetable garden, see video:
