Mosquitoes are attracted to certain compounds that are present on human skin and in sweat. These compounds give us a specific odor that can draw mosquitoes in.
Several different compounds have been identified as being attractive to mosquitoes. Some that you may be familiar with include lactic acid and ammonia.
Researchers are still investigating the causes of the variations in body odor that make certain people more attractive to mosquitoes. Causes could include genetics, certain bacteria on the skin, or a combination of both.
Body odor itself is determined by genetics. If you’re related to someone who is often bitten by mosquitoes, you may be more susceptible too.
