Why do mosquitoes sting and why does it itch?

Of all mosquitoes, it is only the females that seek blood. When a mosquito stings, she sucks blood to extract proteins from it. She needs those proteins to develop her eggs. 48 hours after her “meal,” she lays her eggs.

It is not the sting itself that causes irritation. A mosquito stings for only a few seconds and sucks up barely 5 millionths of a liter of blood. That's too short and too little to feel it at the time it happens.

So how do you get that stinging, itchy feeling and thick bump? We owe that to the saliva of Mrs. Mosquito. When a mosquito sucks up blood, it leaves behind saliva so that the blood it wants to suck up doesn't clot immediately. The saliva provokes a small inflammation at the site of the bite to which your body reacts. So an itchy mosquito bite is the result of an immune reaction.
