Scientists haven't narrowed down exactly why some people are more appetizing than others, but they have a few ideas. Click through the gallery for some hints on becoming less delicious.
Cool off – Mosquitoes are attracted to an abundance of chemical compounds in your body, including carbon dioxide, according to Dr. Lyle Petersen, director of the division of vector-borne infectious diseases at the Centers for Disease Control and Protection. We're not usually ones to advocate inactivity, but mosquitoes are also attracted to sweat and heat, Petersen says. More specifically, they're attracted to the lactic acid in your sweat. Do your workout indoors to avoid getting infected by something other than runner's high.
Stay indoors – Mosquitoes that carry West Nile virus, called culex mosquitoes, are most active at dusk and dawn, Petersen says. But other types of mosquitoes are active all day long, so your best bet is to stay inside.
