For tonight's "Doctor On Call" question, we go to Lafayette. This viewer writes, "I have two daughters and when they're out playing, one gets tons of mosquito bites, while the other hardly gets any. What could explain this?"
Each person's body chemistry determines how many mosquitoes will come calling. The American Mosquito Control Association says mosquitoes can detect their targets from nearly 100 feet away. They're looking for the scent of carbon dioxide and lactic acid and each person produces different amounts. They also like body heat and while the daughter who attracts mosquitoes can't change her body chemistry, you can use a repellent with oil of lemon eucalyptus, which is safe and effective for children. Because the insects like darker fabrics better than lighter ones, be sure to stay away from black and blue clothing.
