They are effective for a long time, as they remain unchanged on surfaces. It is only important not to wash off the drug for a certain period. Infected insects carry poison to other individuals, which ensures the complete destruction of the colony, including eggs and larvae.

WATER BASINS AND GRASSY PATCHES IN ADJOINING AREAS
Creating comfort and coziness for ourselves, we thereby unwittingly create conditions for the settlement of mosquitoes. The lawn of up to 10 cm will not commpletely dry out after watering until several days later. Add to this also a pond, no matter whether it is behind a fence or on the territory adjacent to your country house, and mosquitoes will not make themselves wait. Their If anything, they will appear with a speed of lightning. If they are comfortable enough on the territory, it will be impossible to get rid of them on your own.
DAMP HOUSE BASEMENT
The appearance of mosquitoes in apartment buildings is a fairly common occurrence. The reason, unfortunately, is commonplace – the flooding of the basement of the building. Even the smallest puddle is an ideal breeding ground for mosquitoes, not to mention the whole flooded basement.
They enter the apartment through the water duct and ventilation ducts. With air currents circling inside the walls, mosquitoes can enter any apartment on any floor. Therefore, do not be surprised that mosquitoes appear on floors 17 or 20.
FLOODING OF THE APARTMENT
Flooding of an apartment by neighbors is one of the most common causes of mosquitoes at home. Quite often, the water remains in the ceilings and does not completely dry out, causing dampness in the room and creating all the same ideal conditions for the appearance and reproduction of mosquitoes.
