Do you know why mosquitoes don’t bite others but prefer to bite you?

First of all, the mosquitoes that bite you are usually female mosquitoes because they need to absorb nutrients to lay eggs. Secondly, mosquitoes rely on smell and temperature to find prey, and can keenly sense the surrounding carbon dioxide concentration. If you have developed sweat glands and a high body temperature, you will be an easy target for mosquitoes. Once the target is confirmed, the mosquito will carefully land on your skin, and then give you phlegm to numb your physical pain.

Scientists discovered through microscope observation that the mosquito's mouth is composed of six stylets, each responsible for different tasks. After paralyzing the skin, they will first use their jagged upper and lower jaws to cut open your skin, then insert the needle into your flesh and stir it around until they find your blood vessels. After finding the blood vessel, the mosquito will use the needle in the middle to inject saliva to prevent blood clotting so that it can better absorb food. Finally, a mouth needle is the text, a tool used to enjoy delicious food. If you fail to discover it in time, after it flies away, the bite area will be abnormally itchy. This is because the mosquito saliva left on the skin causes allergies, and at this time your body mechanism will release chemicals to the bite site and produce an antigenic reaction, which results in a large swelling on your skin. If you find that the total package this time is larger than usual, it's because the mosquito that bit you is a newbie and spits out more when looking for blood vessels, that's all. And mosquitoes are the source of the spread of many viruses, because there are thousands of them, coupled with the frequent replacement of mosquitoes, allowing viruses to spread and spread everywhere.

So in the summer, we must take some measures to deal with mosquitoes, such as drought, using some special smells in the bath to block their position, such as candles, herbs, plant essential oils , in fact, all of them can be used. If you want to have a good night's sleep with peace of mind, be sure to learn to use these techniques.
