If you’ve ever been at an outdoor party or BBQ during the fading hours of daylight and don’t personally notice an increase in the number of mosquitoes, you’ll probably hear someone complaining about it. That’s because mosquitoes are selective insects, and some people are more likely to get bites than others.
There are a few factors that could contribute to why this happens: In one controlled study by the Journal of Medical Entomology, the bugs landed on people with blood Type O nearly twice as frequently as those with Type A. The researchers noted this has to do with secretions we produce, which tips mosquitoes off on a person’s blood type.
[In addition,] “Body heat is a really important tactile cue,” [entomologist Jonathan] Day said. “That comes into play with genetic differences or physiological differences. Some people tend to run a little warmer.”
Just because you might be more prone to bites doesn’t mean they have to be an inevitability.
“One of the very best things to do is to avoid peak activity times [for mosquitoes],” Day said. “There are very, very few species that are active in the middle of the day.”
