When are the most mosquitoes?
Studies have found that the most mosquitoes are at dusk and dawn. In summer, when the most active temperature at dusk is between 28℃ and 33℃, the mosquitoes have the strongest activity, and it is also the time when the mosquitoes are the most active.
There are a lot of mosquitoes before the weather is sweltering and raining, which is related to the habits of mosquitoes. Mosquitoes and other insects have chemotaxis, that is, they have a certain tendency and avoidance to certain chemical substances with special smells.
In addition, mosquitoes like to move in dark and humid places. With the tentacles on the eyes and head and the sensitive sensors on the three pairs of feet, it can receive the warm and humid odor, exhaled carbon dioxide, volatile sweat and other secretions on the human body as a "scent language".
Before the weather is sultry or rainy, the humidity in the air is high and the light is weak. The substances secreted by human skin cannot be quickly volatilized due to the sultry heat. These conditions have an attracting effect on mosquitoes, which can be smelled "downwind". Therefore, before it rains and when the weather is sultry, people feel that there are a lot of mosquitoes.
Mosquitoes are most active at two times a day, one is dusk and the other is dawn, especially at dusk. Doors and windows are open, people come and go frequently, and mosquitoes can easily get into the house. Therefore, lighting mosquito coils at dusk can effectively repel mosquitoes.
