When it enters the blood, on the one hand, it will increase the permeability of blood vessels. It allows immune cells to quickly accumulate in the blood-sucking area and swallow harmful substances left by mosquitoes; on the other hand, it will cause the surrounding blood vessels to dilate, which can bring more body fluids to the target area, dilute anti-hemagglutinin and mosquitoes. Acids and other substances that are toxic to the human body can cause local prolongation and itching. Some people have a milder immune system and may only leave a small red spot after a mosquito bite; some people have a more aggressive immune system, which may cause skin swelling, formation of pimples (mosquito bags), and severe itching; others It may produce general rubella and angioedema, and even cause severe asthma.

These conditions have an attracting effect on mosquitoes, allowing them to smell The wind" comes. The study found that mosquitoes have two peaks of attack during the day: early in the morning to 9 am and around 6 in the evening.

Incense and wormwood, the most obvious of which is pyrethrum, has a strong repellent or even killer effect on mosquitoes. Mosquitoes also don't like the smell of lemongrass oil, citronella and geraniol.
