Flies are attracted to humans due to the odors and carbon dioxide we emit. They are drawn to body heat and the moisture in our breath, along with certain odors from our skin or from perfumes and foods. Flies have compound eyes that are adept at detecting movement, making moving objects, including humans, more noticeable to them. Keeping clean and minimizing exposed food can help reduce your attractiveness to flies.
