Why does it itch so bad when a masquito bites?

Answer:
When a mosquito bites you (it's actually a puncture, not a bite), it first injects a little bit of saliva that contains a chemical that prohibits blood clotting so it can drink without problems. This chemical is a skin irritant to most people and causes a very localized histamine reaction, resulting in swelling, redness and itchiness.

When a mosquito bites, it injects saliva to help the blood clot in you then sucks blood out. The saliva is a poison to your body, so when white blood cells show up to stop the invading poison it results in the itchy feeling.That's my best most educated guess. But I know the saliva being injected part is right lol
