If mosquitoes love you, new research suggests it may be because of how you smell
FILE - This 2006 file photo provided by the Centers for Disease Control and Prevention shows a female Aedes aegypti mosquito in the process of acquiring a blood meal from a human host. A study published Tuesday, Oct. 18, 2022, in the journal Cell, finds that certain people really are “mosquito magnets” who get bitten more than others — and it probably has to do with the way they smell.
There’s a lot of folklore about who gets bitten more but many claims aren’t backed up with strong evidence, said Vosshall. “They would basically swarm to the most attractive subjects,” De Obaldia said. “It became very obvious right away.” By testing the same people over multiple years, the study showed that these big differences stick around, said Matt DeGennaro, a neurogeneticist at Florida International University who was not involved with the research.Out of the favorites, the researchers found a common factor: Mosquito magnets had high levels of certain acids on their skin. These “greasy molecules” are part of the skin’s natural moisturizing layer, and people produce them in different amounts, Vosshall said.
Still, figuring out ways to fight off mosquitoes isn’t easy, Riffell said, since the critters have evolved to be “lean, mean biting machines.”
