Science Explains Why Mosquitoes Prefer Certain People

People with blood type O are bitten by mosquitoes twice as much as those with other blood types, according to researchers in Japan.

Mosquitoes can detect carbon dioxide exhaled from up to 100 feet away; pregnant women and those who exercise exhale more CO2 and are easier targets.

Sweat contains lactic acid, ammonia, and carboxylic acid, which mix with skin bacteria to create an odor that attracts mosquitoes.

Wearing dark-colored clothing (black or dark blue) makes you a more visible target for mosquitoes than light-colored clothing.

Mosquitoes prefer people with higher body temperature, those who sweat more, and those who consume alcohol, as it raises body temperature and changes sweat odor.
