Are You A Target? Mosquitoes Have a Favorite Blood Type In Central Texas

If you spent time outside over the weekend, you probably encountered some mosquitoes. The recent rains in Central Texas have created a breeding ground for the flying syringes, and if it seems like they are hyper focused on “you” and no one else, there is a scientific reason.

How Your Blood Type Shapes Mosquito Appeal

For most of us, the only time we worry about our blood type is if we are giving it or receiving it. According to Healthline, recent studies have found that whether you have type A, B, AB, or O blood influences everything from heart issues to how attractive you are to pests. While epidemiologists emphasize that there is no single "optimal" blood group, each blood type presents a distinct matrix of physiological advantages and health liabilities.

The Chemical Magnets: Type O and Mosquito Attraction

I knew this was the case before I ever came across the information online. My blood is a fine wine in the mosquito world. The National Blood Institute has bad news for those of us with type O positive or O negative blood: We are significantly more prone to mosquito bites (as I write this with a HUGE bite on my neck from earlier today). Studies conducted in 2004 and 2019 confirmed that mosquitoes bite type O individuals at a drastically higher rate than any other group. Good news for you Type A people...they don’t dig you.

How Do Mosquitoes Find Us?

Beyond microscopic blood chemistry, mosquitoes hunt using a combination of sensory inputs, meaning you can lower your profile by knowing what the bugs like and doing the opposite. Mosquitoes are attracted to carbon monoxide (heavy breathing), high body heat/sweat, dark clothing, skin bacteria, and body odor. Great. I stink.
