Flies, including common houseflies, are drawn to humans mainly due to the heat, moisture, and the carbon dioxide we exhale. Additionally, if you've been sweating or eating, the odors and salts on your skin can also attract them. Keeping your skin clean and avoiding leaving food out can help minimize their interest in landing on you.
