The common house fly (Musca domestica) multiplies rapidly and is one of the most prevalent of all insect pests. It has been associated with over 100 different disease pathogens, including salmonella, cholera, and tuberculosis, so it is important to manage pest outbreaks. They leave fecal spots, or “specks,” where they have walked, and in this way may transfer disease organisms to humans and animals. In rural areas, flies can be a nuisance when they gather on the outside walls of homes and buildings on summer evenings.
Because houseflies can carry many diseases to humans and domestic animals, it is important to keep their populations low. Understanding their habits and life cycle can help you eliminate the most flies at the lowest cost to you and the environment.
