Beer Lovers Beware: Study Finds Mosquitoes Prefer Boozy Blood

Amsterdam, Netherlands — Beer might get you buzzed, but Dutch scientists warn it could also make you more appetizing to mosquitoes.

A research team led by Felix Hol of Radboud University Nijmegen set out to understand why some people are mosquito magnets. Their study, published on preprint server BioRXiv, suggests that alcohol consumption — especially beer — can increase your chances of being bitten.

To test their theory, researchers set up a pop-up laboratory at Lowlands, an annual music festival in the Netherlands. More than 500 volunteers were asked about their diet, hygiene, and behavior before sticking their arms into a custom-made mosquito box. The device allowed mosquitoes to smell participants but not bite them, while cameras tracked the insects’ landing patterns.

The results were striking: festivalgoers who drank beer were 1.35 times more attractive to mosquitoes than their sober counterparts. But beer wasn’t the only factor. The study also found mosquitoes were more drawn to those who skipped sunscreen, showered less, or had shared their bed the previous night.

“We found that mosquitoes are drawn to those who avoid sunscreen, drink beer, and share their bed,” the team concluded. “They simply have a taste for the hedonists among us.”

Interestingly, it’s not the alcohol itself that lures the insects, but rather scent changes linked to lifestyle and behavior. “People who have been drinking alcohol also behave differently,” Hol explained in a Dutch radio interview. “At a festival like Lowlands, they might also be dancing more exuberantly, which can change their body odor.”

Scientists note that mosquitoes can detect human scent from up to 350 feet away, making body odor a key factor in attraction.

However, the study’s sample had limitations. Participants were mainly young and healthy festival attendees, which may not represent the general population.

Still, the findings could help explain why some people seem like irresistible targets for the bloodsuckers — especially after a night of partying.
