What's inside a Mosquito bite, and why does it swell up?

Why does an average mosquito bite swell?

  • Everybody knows those little bumps on their skin when they get a mosquito bite, but why does it swell. All i have learned is that the mosquito simply sucks blood from you. Does it inject something in return?

  • Answer:

    Yes, it injects tiny amounts of an anesthetic, so that its victims are less likely to feel the 'bite'. Most people have a mild allergic reaction to this, which causes histamine to build up in the tissue around the bite, hence the swelling and itching.

Yes it injects something to thin the blood, and the swelling is an allergic reaction.

no they do not. Your body develops a reaction and sometimes the natural histamine in your body is less than other times. When it is lower is when you have more swelling.

yes, protein, tranquilizer so you don't feel the critter

The misquito deposits a chemical on your body to make it easier to get the blood out. Most people are allergic to it. That is why antihistimines/cortisone is effective in relieving the itch.
