Why are some people mosquito magnets?

If you feel as if every mosquito in a 50-mile radius has you locked in its sights, while your friends are rarely bitten, you could be right. Up to 20 percent of us are highly alluring to mosquitoes—and scientists have discovered some surprising reasons.

“Both your metabolism and your unique body chemistry—which is as distinctive as a fingerprint—play an important role in determining whether or not you’re a mosquito magnet,” says University of Florida entomology professor Dr. Phil Koehler. “Also, there’s evidence that your degree of attractiveness to mosquitoes can change over time.”

Here are some intriguing discoveries about why some of us are particularly tasty targets for the tiny vampires:

Mosquitos prefer blood type O

In their quest for a meal, mosquitoes are nearly twice as likely to land on people with type 0 blood than those with type A, according to a Japanese study.  Indeed, the biting pests consider type 0 more delectable than any other blood type, the researchers reported. Most people secrete substances that allow mosquitoes to identify blood type before they bite.

Beer drinkers beware

Swigging just one bottle of beer can significantly boost your risk of being bitten, according to a study published in Journal of the American Mosquito Control AssociationThe researchers reported that, “Mosquito landing on volunteers significantly increased after beer ingestion compared with before ingestion.”

Watch out for the full moon

The tiny bloodsuckers are 500 times more active when the moon is full, reports theAmerican Mosquito Control Association (AMCA). Overall, the highest risk times for mosquito bites are dusk and dawn, with the females of some species migrating up to 40 miles in pursuit of a meal. (Male mosquitoes don’t bite.)

Keep your socks on

The pungent aroma of dirty feet is apparently irresistible to mosquitoes, as a brave scientist, Bart Knols, discovered when he sat in a lab in his underwear to find out which parts of the body the pests are most likely to target. He found that 75 percent of the bugs homed in on his feet, but after he washed them with deodorant soap, the mosquitos bit randomly. His team also reported that stinky cheeses, such as Limburger—which has the same odoriferous compound responsible for foot odor—also draws mosquitoes.
