How does mosquito repellent work?

The female mosquitoes are the only mosquitoes that bite. They are collecting the protein in blood to develop their eggs. Mosquitoes are attracted to skin odors and carbon dioxide from breath. The ingredients in repellents make the person unattractive as a food source, but are only effective for short distances from the treated area. DEET, Picaridin and oil of lemon eucalyptus are all registered with the EPA for use as mosquito repellent.
