Why do mosquitoes bite us

Why do mosquitoes bite us?

Only female mosquitoes bite. They require a "blood meal" in order to develop eggs to make more mosquitoes. 24 hours or so after hatching, a female mosquito flies off in search of a meal. She homes in on
body warmth, odor moisture and the carbon dioxide we exhale. When she bites, she injects a bit of saliva that slows coagulation so blood flows
freely. It's your body's allergic reaction to the saliva that causes the welt and the itch later on.
