Why don’t I get bumps from mosquito bites?
03/8Reaction: None REACTION: NONE: If you don’t happen to hate mosquitoes because you feel they don’t bite you or if they do, the bites don’t leave any marks, you are a lucky person!

Can you build immunity to mosquito bites?
3. You can develop an “immunity” to mosquitoes. In response to a mosquito’s bite, your body usually reacts to the saliva by releasing antibodies that create the small, itchy welt. Over time it develops a tolerance, and stops reacting because it stops recognizing the mosquito saliva as a foreign invader.
Why don’t you feel mosquito bites until the next day?

Why do some mosquito bites itch more than others?
Your likelihood of getting bitten comes down to the level of carbon dioxide in your body and the way your skin smells. While no one is completely immune to mosquito bites, these factors make some more prone to bites than others — and along those lines, some folks have worse reactions to the bites, as well.
