-Widely distributed throughout the world, the common house fly (Musca domestica) is one of the most prevalent of all insects, which can make fly control difficult. Flies belong to the insect order Diptera and are related to mosquitoes and gnats.
- Flies are cold-blooded insects that move about looking for external heat sources; most flies are diurnal and are attracted to certain wavelengths of light. Flies buzz around windows and can be easily vacuumed up by windows or lights. Most flies have large compound eyes and usually three simple eyes. Each of the fly’s compound eyes has about 4,000 six-sided lenses- so they can detect the slightest movement. Flies taste with special hairs on their feet. The larvae or maggot is legless and the head is often reduced or indistinguishable and retracted into the thoracic segments. Flies can range from tiny midges less than 1/16” long to huge robber flies more than 3” long.
-Adults are strong fliers, and can travel up to 20 miles, although they are found primarily within two miles of the larval food site. When feeding, house flies regurgitate liquid from the stomach to dissolve food, then use their sponging mouthparts to suck it up.
-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.
-House fly adults (1/6 - 1/4 inch long) are dull gray in color with reddish-brown eyes. They have two membranous wings and four dark stripes down the middle section of their body (thorax). Females are usually larger than males and can be distinguished by the space between their eyes, which is almost twice the distance as in males. The larval stage (3/8 - 3/4 inch), also known as a maggot, is soft, cream-colored, and worm-like. They are typically found...
