If it seems like mosquitoes choose you over everyone else, you’re not imagining things. “Some people give off different compounds that make them more attractive to mosquitoes,” says Michael Riehle, Ph.D., professor of entomology at the University of Arizona. The bad news is that a lot of this comes down to your genetic makeup, which you obviously can’t change, so bug spray is always your best line of defense. (Dr. Riehle says 25 percent DEET works just fine.)
Still, there are a few lifestyle factors that might be making you a mosquito magnet. Be diligent if you fall into any of the categories that follow.
