Why is it so cold and there are so many mosquitoes in the room?

Mosquitoes don't exist with the seasons. Their living conditions are about 20℃. If the living environment is suitable, mosquitoes will have the conditions for growth. In winter, mosquitoes hide in dark corners just because the temperature is too low. If the heating is turned on at home and their living environment is reached, they will come out again.

Mosquitoes like to hide in dark but warm corners. There are mosquitoes in your house in winter-you must provide them with suitable living clothes. Domestic garbage such as kitchen waste and toilet waste is not discarded in time. Don't think that garbage won't ferment for a few days because of the low temperature in winter. At that time, mosquitoes may lay eggs in garbage bags.

Mosquito hazard

Among mosquitoes, the most hateful is the mosquito that sucks human blood. Male and female mosquitoes have different feeding habits. Male mosquitoes are "vegetarians" who specialize in feeding on nectar from plants and juice from fruits, stems and leaves. Female mosquitoes occasionally taste the juice of plants, but once they get married, they will feed on blood. Because it can only develop ovaries after sucking blood. So only female mosquitoes bite and suck blood.

There are many spiral sensory hairs on a pair of antennae and three pairs of feet of mosquitoes, and each sensory hair is densely arranged with round or oval pores. In the dark, mosquitoes can sense the carbon dioxide emitted by the human body in the air through this sensor, respond within 1‰ second, and fly to the blood-sucking object correctly and in time.

Before sucking blood, mosquitoes inject saliva containing anticoagulant under the skin and mix it with blood, so that the blood becomes thin plasma that will not coagulate, and then spit out undigested old blood and suck out fresh blood. If a person bites 654.38+100000 mosquitoes at the same time, he can absorb human blood.
