Houseflies, as their name would indicate, are the most common flies found in and around the home. Like other flies, they are a nuisance and carry multiple disease organisms. Houseflies are dull gray in color with four dark stripes on their back. They are attracted to smells, moist places to lay eggs and air currents from buildings. To control houseflies, it is important to identify and inspect the flies’ habitat, clean the surrounding area of excess garbage and apply the appropriate pesticide.
