Scientists Finally Reveal Why Mosquitoes Bite Some People More Than Others

Millions of people notice the same strange thing every summer. A group of friends can sit outside together for hours, yet one person ends up covered in mosquito bites while another barely gets touched.

For years, many believed it was just bad luck. However, scientists have discovered that mosquitoes don’t choose their targets randomly. Certain factors may make some individuals far more attractive to mosquitoes than others.

Research suggests that body temperature, skin chemistry, blood type, and even the bacteria naturally living on the skin may influence how attractive a person is to mosquitoes. Carbon dioxide also plays a major role. Mosquitoes can detect the carbon dioxide people exhale from surprising distances.
