Temperature, light, sound and smell are the four major factors that affect mosquito blood-sucking. Generally speaking, mosquitoes bite at 16℃ to 17℃, and the most suitable temperature is 23℃ ~ 39℃. When a mosquito tracks a target, it always twists and turns with the smell of people's breath until it touches the target and then falls on the skin, patiently looking for a "breakthrough". Finally, directly insert the "needle tube" into the skin to suck blood for 8 ~ 10 seconds.
Is the human body capable of sending out "signals" to mosquitoes? Strong "signals" spread through the air and can guide them to find food conveniently.
Don't underestimate a mosquito only one centimeter long. It has a strong search ability, and the farthest search distance can reach 60 kilometers. In this range, the stronger the "signal", the easier it is to be locked by them.

Mosquito-attracting person
1, people who have drunk wine
Why do people have different "attraction" to mosquitoes? This is mainly related to the difference between the smell of human excrement and the amount of carbon dioxide emitted by the human body, and mosquitoes rely on the carbon dioxide emitted by the human body to find their targets. After drinking, the amount of carbon dioxide discharged increases, which can attract a large number of mosquitoes to sniff and bite repeatedly.
2. People with large lung capacity, fat people and people with heavy breathing.
People will breathe faster after engaging in sports or physical labor, so that they will exhale more carbon dioxide, and the carbon dioxide gas will form a moist and warm airflow at the head of about 1 m, which is sensitive to mosquitoes, and the "image" presented in their own field of vision is clearer, which is convenient for mosquitoes to track directionally.
Therefore, in a group, people with large lung capacity, fat people and people with heavy breathing are more likely to be bitten by mosquitoes.
3. People with developed sweat glands
People who like sweating have increased blood acidity and are attractive to mosquitoes. In addition, there is a heater in the antenna of mosquitoes, which is very sensitive to temperature, and can be detected immediately as long as there is a little temperature difference change. People who sweat lose heat quickly and attract mosquitoes. Sweat excreted by human body volatilizes in the air, which can also send a "signal" to mosquitoes.
Therefore, people who sweat a lot and sweat easily are more vulnerable to mosquito attacks. Mosquitoes love to bite people with rough skin and large pores, usually because such people often have developed sweat glands or secrete more secretions such as sweat. So sometimes men attract mosquitoes more than women, and young people attract mosquitoes more than old people.
