The house fly (Musca domestica) is the most common of all domestic flies, accounting for about 91% of all flies in human settlements, and indeed one of the most widely distributed insects, found all over the world. The larvae of this species and its relatives feed in manure or decaying organic matter. The ability of housefly larvae to feed and develop in a wide range of decaying organic matter is very important for recycling of nutrients in nature. Adult flies feed on a large variety of liquid food and regurgitate their food to liquefy solid particles in their food.
The house fly is known to transmit the microorganisms responsible for a variety of diseases such as dysentery, cholera, and typhoid fever. The best way to avoid any of this is good hygiene.
When doing my research for this post I also found this very interesting recommendation to keep the flies at bay: attaching clear plastic bags, half full of water, outside doors and windows. The constant motion of the water interferes with the insect’s vision.
