Why does a mosquitoe bite itch?

I have tons of mosquitoe bites and they all itch like cray! What makes them itch so bad?!
Answer:
When a mosquito bites you, she injects her own saliva, because it contains anticoagulants which will keep your blood flowing instead of clotting. Unfortunately, along with those anticoagulants she also unavoidably injects some of her own body's proteins, and these happen to produce an allergic effect in us. A class of chemicals called histamines binds to these foreign proteins, which provokes an inflammatory and itchy response in the cells roundabout, until our own body's immune system can break up the proteins and clear them away.It is best not to scratch if you can help it, because scratching damages the inflamed cells around the bite, and helps the mosquito's proteins spread even further.
Your skin (body) is reacting to the saliva the mosquito bite leaves. Likely from the mosquito having bit other people then you.
Mosquito spit. :)Seriously. When a mosquito bites you and takes some blood, it also leaves behind a little bit of saliva, which your immune system reacts to, making you itch. If you want it to stop, try a little hydrocortisone cream. That should help. And don't scratch, or you'll just spread the mosquito spit!
AS THEY ARE SUCKING YOUR BLOOD,THEY INJECT A POISON LIKE FLUID UNDER YOUR SKIN AND IT CAUSES IRRITATION/ITCHING.AVOID MOSQUITO BITES BY USING INSECT REPELLENTS.MOSQUITOS TRANSMIT DISEASES/ILLNESSES FROM ONE TO ANOTHER I THINK SO PROTECT YOURSELF.
Only the female mosquitoes bite. When they do, they inject chemicals that allow the blood to flow easily into their mouths. It is these chemicals that cause your skin to be irritated and itchy. You can read more here:
