Hello,
Why does it swell when a mosquito bites you on the skin?
Thank you.

Hello,
This is because of the bacteria and also because it leaves up an air gap while sucking the blood.
Take care.

It's due to a person being allergic to the saliva of the mosquito. It contains a blood thinning agent that helps them suck out your blood more easily. Some people are more allergic to it than others.
