Those annoying summer bug bites are not just a random occurrence. Scientists have found that mosquitoes actually have favorites--that is, they are more attracted to certain people than others. According to research reported by Smithsonian.com, mosquitoes tend to be more attracted to pregnant women, people who have just exercised, those who have consumed alcohol, and people with certain blood types.

Dr. Christine Le from Houston's Kelsey-Seybold Clinic says there is a reason why the biting bugs are drawn to certain people. "Pregnant women seem to make more carbon dioxide, and unfortunately that seems to attract more mosquitoes," she tells KTRH. The same holds true for those out for an evening jog. "If you're exercising and you're warm, the mosquitoes can sense that carbon dioxide and attack, so it may be a good idea to make sure you have mosquito repellant on prior to exercising," says Dr. Le. As for the alcohol attraction, scientists haven't been able to come up with an explanation for that, but they say just one beer can make a person more attractive to mosquitoes.

Ultimately, researchers say the biggest factor that determines whether someone is a "mosquito magnet" is their genes, which can't be controlled. That's why everyone should use common sense measures to prevent mosquito bites in the summertime. "Number one, apply insect repellant, number two, cover up...try to wear long-sleeved shirts, long pants and socks while outdoors," says Dr. Le. But be careful what you wear--even brightly colored clothing can attract mosquitoes. "They can see from a pretty far distance," says Dr. Le. "Also, it's important to avoid mosquitoes during their prime feeding time, which is between dusk and dawn."
