| FLY INFORMATION |
| FILTH FLIES: Several species of flies can be found in and around homes during the warm periods between Spring, Summer and Fall. These medium sized flies are attracted to human and animal waste and decaying garbage. Because of these habits, they are capable of transmitting filth-related diseases such as diarrhea and dysentery. All flies belong to the insect order Diptera meaning "Two-winged." Most other adult insects have four wings. Flies have four life stages: egg, larva, pupa and adult. Eggs are laid in a variety of decaying organic material, and hatch into pale, legless maggots. When development is complete, the maggots wander from the larval development site in search of a dry place to pupate. The pupa is the immobile stage characterized by a hard, dark brown "shell." The adult flies may emerge in as little as seven to fourteen days. HOUSE FLY (Musca domestica): Distributed throughout the world, the house fly is one of the most common of all insects Adults are dull, medium-gray flies 1/6 to 1/4 inch long with four dark stripes on the thorax. They have sponging, non-biting mouthparts for sucking up liquified foods. Female house flies live for three or four weeks and lay batches of 75 to 100 small, white, oval eggs, usually in garbage, but also in manure and decaying vegetation. House flies are strong fliers, and can fly 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, house flies can be a nuisance when they gather on the outside walls of homes and buildings on summer evenings. BLOW FLY (Family Calliphorida):Blow flies are sometimes know as blue or green bottle flies. They generally range from 1/4 - 1/2 inch long, and are characterized by metallic blue- green or copper-colored bodies. In urban areas they are sometimes more abundant than house flies. Females lay eggs on garbage containing meat scraps, as well as on dead animals and animal wounds. They may also deposit eggs onto feces-caked hair or wool on pets and other domestic animals. Blow fly larva (maggots) develop rapidly in warm weather, and maggots often reach their full size on the second or third day after hatching. The entire life cycle usually requires between 10 and 25 days. If an animal or bird has died indoors and is hidden in a chimney, wall void or ceiling a sudden population of adult blow flies may be seen a number of days later. As maggots mature, they move away from the carcass to pupate. STABLE FLY (Stomoxys calcitrans): Stable flies resemble house flies but have "checkerboard" markings on the abdomen and bayonet-like mouthparts used to pierce skin and suck blood. They are about 1/4 inch long, and are sometimes called "biting house flies." Both sexes can inflict a painful bit, feeding on the blood of warm-blooded animals including humans, horses and cattle. Dogs kept in kennels outdoors may be bitten severely, especially on legs and ear tips. Stable flies are able to bit through clothing. and particularly attach the ankles. They are strong fliers any may fly long distances for a blood meal. |
