Why are there a large group of mosquitoes flying overhead at night?

1, people with developed sweat glands and high body temperature. Mosquitoes have a heater in their antennae, which is very sensitive to temperature. As long as the temperature difference changes a little, it can be detected immediately. People who sweat lose heat quickly and attract mosquitoes.

2. People who are tired or breathing fast. People will breathe faster after engaging in sports or manual labor. Some people have larger lung capacity or faster breathing rhythm. In this way, the exhaled carbon dioxide is more, and the carbon dioxide gas will form a moist and warm airflow at the height of 1 m above the head. Mosquitoes are sensitive to this and will smell it.

3. People who like to wear dark clothes. Mosquitoes don't sleep during the day and go out at night, mainly because they have the habit of dark. If they wear dark clothes, they will have a black shadow at night, and mosquitoes will chase them to darker places. The color of clothes, such as black, is the first choice for mosquitoes to attack, followed by blue, red and green. Mosquitoes don't like to bite white.
