Customised Pest Control for the Adelaide Area


Online Pest Library - Flies


Flies 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. 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 faecal 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.

Note: House flies are known to spread diseases such as conjunctivitis, typhoid fever, tuberculosis, anthrax, cholera, diarrhea and dysentery.

Life Cycle
Females deposit 2-21 egg masses, each containing about 130 white eggs in manure or fermenting vegetation such as grass clippings and garbage.

Hatching takes place in 10-24 hours; the young maggots become fully grown in 3-7 days, crawl to the margins of the breeding material and pupate.

The papal stage may vary in length considerably, but in warm weather can be about three days. When adults emerge they begin mating immediately. An entire life cycle; egg, larva, pupa to winged adult may occur in 6-10 days under warm, moist conditions. Adults may live an average of 30 days.

Fly Control
Sanitation is the most effective and important step in controlling house flies. Dry and wrap organic waste before placing it in the garbage can. Seal garbage cans with tight fitting lids. Screen windows and doors to keep pests out. Use indoor fly traps or sticky tape to control pests inside the house. Keep the Big Stinky outdoors to reduce the number of adult pests during warm weather.

Tip: Plain boiling water is an excellent (and inexpensive) way to kill maggots in garbage cans.
