SAN ANTONIO -- Summer is in full swing and people are taking advantage of the nice weather by heading to the park or taking a spin on the water, but with hot temperatures come a pest – mosquitoes.

So what causes mosquitoes to be attracted to you? According to the Smithsonian Institute, the blood sucking critters have a heavy appetite for people with Type O blood.

Diego Rivera said that is probably the reason they attack him and his daughter.

“Me and my daughter, there's been a lot of bites everywhere and I think they're getting worse,” Rivera said.

This week, the Texas Department of State Health Services confirmed the state's first human case of Chikungunya, a viral disease spread to people by mosquitoes.

Garcia said because of the mosquitoes, an outing to the park is a rare treat for her grandchildren.

“Basically we just stay home, avoid them and like to stay inside,” Garcia said.

The Smithsonian said mosquitoes are attracted to people who exercise. Researchers said they smell certain chemicals released from sweat and they like people with higher body temperatures.

The insect also uses vision. The Smithsonian said wearing colors like black, dark blue or red make you an easier target.

"Right before you guys walked up, I got a bite and that was the first bite for the season,” Deborah Brown said.

In several different studies, pregnant women have been found to attract roughly twice as many mosquito bites as others.
