Found on every continent except Antarctica, the house fly is one of the most familiar of all insects. House flies are generally found in greatest numbers during the hotter summer months and generally live in close proximity to humans and animals. These pests breed in animal wastes and decaying organic material, including animal corpses and food waste from which they can pick up bacteria and viruses that may cause human disease. House flies defecate most every time they land, contaminating food, with the potential to spread disease.
House Fly Habitat
In rural areas, manure piles are often the main source of house flies, and in urban areas, piles of fermenting lawn clippings commonly generate large numbers of flies. Animal manure is a favorite breeding medium for flies with the most important sites being horse manure, human excrement, cow manure, fermenting vegetable refuse, dumpsters and refuse containers, and household garbage. Some species of flies can live and breed in recycling containers, and fly problems are common in recycling centers.
House Fly Behavior – Threats – Dangers
Although house flies do not bite, they are capable of transferring more than 100 different pathogens, including salmonellosis, typhoid, and tuberculosis. Pathogenic organisms are picked up by flies from garbage, sewage, and other sources of filth, and then transferred on their mouthparts, through their vomitus, feces and contaminated external body parts to human and animal food. They can carry a wide range of germs from filthy breeding sites to the dinner table or spread some diseases within herds or flocks.
House Fly Prevention
To prevent house flies in your home, employ these sanitation and exclusion methods. Keep kitchens and bathrooms clean, wipe up any spills quickly, and do not leave dishes in the sink overnight. Regularly pick up and dispose of pet feces in sealed trash bags. Repair screens on windows and doors to limit access to house flies. Use a silicone-based caulk to seal around vents, cracks, holes in foundation, windows, and doors. Sticky fly traps, swatters, and light traps are all proven methods to help eliminate flies that have already found their way inside.
