Flies fly in front of you mainly due to their attraction to the carbon dioxide and heat your body emits. Flies have compound eyes that allow them to detect movement and heat signatures efficiently, making humans walking through their environment an obvious target. Moreover, if you're eating or surrounded by food, your scent further draws them in. To deter flies, minimize exposed food and consider using natural repellents like citronella or eucalyptus.
