House Flies are commonly found in garages, spoiled food, and even feces, but they also prefer to congregate in corners, edges, or thin objects. In the day, they may be seen on the ceiling, floors, and walls. A House fly infestation can cause health complications since they can contaminate food and water and carry diseases like typhoid and tuberculosis. While they have a short lifespan, their population can increase rapidly. The first step to eliminate house flies in the home is to locate the main source of the infestation and then clean and remove the source to prevent house flies from breeding. It is also important to block and fix damaged areas where future flies can invade and get inside the house.
