How come fleas and mosquitos don't affect some but itch like crazy for other?

Your body's reaction: The itch from bites is not due to the bite itself, but the reaction your body has in response to the bite. When certain chemicals in your body are released you feel the desire to itch. The reason humans have different reactions to the same bug bite is how much of those chemicals are released by different individuals.
