Houseflies are commonly found in close association with human dwellings and are widely distributed in tropical countries. This species is always found everywhere that man exists and has adapted itself extremely well to man’s environment. Flies can have a negative psychological impact because their presence is considered a sign of unhygienic conditions. They are transmitters of diseases primarily because they feed on human and animal wastes. The bacteria present in these wastes, stick to the mouth, footpads and hairs of flies and may then be deposited on food or feed for human or animal consumption.
This species has sponging mouthparts so it cannot eat solid food. It regurgitates digestive fluids onto its food and then sponges up its digested liquid meal.
Any building can be plagued by houseflies, but those located near farms and pastures are likely to experience more flies than other structures. Houseflies rarely breed indoors, but if they do, the site is usually a trash container that hasn’t been cleaned for a while or possibly rotting vegetables or fruit in a box in a restaurant storeroom or kitchen. |
