Mosquitoes are picky creatures — unsurprising if you’re the one always ducking for cover under a swarm of bloodsuckers while your friend remains unscathed. Good thing scientists are on the hunt to discover what makes certain people especially attractive to the tiny insects. Here are nine reasons they’ve come up with so far.
In many ways, no one is immune. The fact that humans breathe makes us all mosquito targets to varying degrees. More than 30 years ago, researchers discovered that carbon dioxide is one of the main reasons mosquitos seek us out. The insects will fly to higher concentrations of CO2 (i.e. - large groups of people at sporting events and backyard parties), then use other sights and smells to narrow down their target.
