The impending arrival of spring and summer means hot days, cool nights, and inevitably more mosquitoes. During the warmer months, our skin is plagued with red, itchy, and scratchy bites despite the use of insect repellent, but why?
Mosquitoes, just like humans, have preferences, even when it comes to blood-sucking.
A 2004 study published in the Journal of Medical Entomology found mosquitoes landed on people with type O blood nearly twice as often as those with type A. Those with type B blood fell in the middle of the spectrum.
The amount of carbon dioxide we exhale also determines how drawn these insects are to us. People who produce more carbon dioxide when they exhale tend to be larger, which explains why children get bitten less often than adults.
A single 12-ounce bottle of beer can make you more attractive to mosquitoes, according to a 2002 study published in the Journal of the American Mosquito Control Association.
