One of the quickest ways mosquitoes can sniff out a person is through the carbon dioxide emitted when we breathe. Mosquitoes use sight and smell to find hosts to bite. Research has shown that mosquitoes are more attracted to the color black, but there has been little additional research into why this is the case. This means movement and dark clothing colors like black, navy and red can stand out to a mosquito. Mosquitoes are highly visual hunters when it comes to finding a human to bite. However, these studies are not definitive, and much is still up in the air about mosquito preferences when it comes to blood type. A 2004 study also found that mosquitoes land on blood group O secretors (83.3%) significantly more than group A secretors (46.5%). A 2019 study observed mosquito feeding behavior when presented with different blood type samples, and found mosquitoes fed from the type O feeder more than any other. While there are no firm conclusions as to which blood type is more attractive to mosquitoes, several studies have suggested people with type O are most appetizing to mosquitoes. There are four main blood types: A, B, AB and O. Blood type is determined by genetics, and each blood type is created based on the different sets of specific proteins, called antigens, on the surface of red blood cells.

Here's why mosquitoes bite and how you can make yourself less of a target this summer. There are actually scientific reasons why mosquitoes single out certain people. Why is that? It's not that I'm particularly unlucky. It's downright infuriating when I come inside sporting several new welts while my friends report that they don't have a single one. If you're like me, you get frustrated by the number of mosquito bites you acquire. Mosquito season starts in March and can last until as late as November in some states. But that time in nature is quickly spoiled when I find myself covered in red, itchy bumps after just a few minutes outdoors. The warm temperatures and consistent sunshine in North Carolina, where I live, mean I can spend more time outside doing things I love: hiking, walking my dog and spending time on the beach or lake.
