How exactly do the mosquito bites make you itch and how can you stop them from itching?

Some help I can do. Mosquitoes are a bit like flying syringes. Their large needle nose, called a proboscis, is ideal for quickly landing on a victim, withdrawing a bit of blood and then taking off for the next target. You may not notice a mosquito bite initially, but within an hour or two after a bite, you may have raised red bumps from mosquito bites that itch like crazy. See belw.
