WASHINGTON — Sometimes it’s hard to define what makes someone attractive. But for those being courted by mosquitoes, it could be due to their genetics.
It’s not the perfume or deodorant on a person, it comes down to three things, says University of Maryland Entomologist Mike Raupp.
“Carbon dioxide, lactic acid and body heat are three of the most important cues used by mosquitoes to locate hosts,” Raupp says.
What someone eats doesn’t matter, but the bacteria on their feet does, he says.
“Smelly feet may really attract them,” Raupp says. “This is part of the reason why most bites often occur on feet and ankles.”
Adults are more likely to be bitten than children; one study found that people with a certain blood type might make better bug snacks, he says.
“One Japanese study found people with Type O blood to be more attractive than those with other blood types, but the mechanism for this is not known,” he says.
And spray on some repellent before heading out for a run.
“Physically active people may be warmer,” Raupp says. “They may give off more CO2 and lactic acid than inactive people, so exercise could also affect your attractiveness to these little vampires.”
