Phorid flies, often called hump-backed flies or scuttle flies, are small insects commonly found in homes and commercial settings. These flies can become a significant nuisance due to their rapid reproduction and their association with unsanitary conditions. Understanding what attracts them is important for effectively managing their presence.
What Lures Phorid Flies
Phorid flies are primarily drawn to decaying organic matter, which serves as both a food source and a breeding ground. This includes rotting fruits, vegetables, and meat products. Spilled drinks, fermenting liquids, and rancid fats also attract these flies. Their larvae feed on these decomposing materials, fungi, and dead animal tissues.
Moisture and dampness are significant attractants, as flies breed in moist environments and require water for larval survival. Standing water, condensation, and consistently wet surfaces create ideal conditions for their development. Their strong sense of smell allows them to detect decaying substances and moist areas from a distance. Specific odors, such as those from sewage or fermenting materials, are particularly appealing to them.
Typical Locations Phorid Flies Gather
Phorid flies frequently gather in locations with decaying organic matter and moisture. Drains are common breeding sites, especially floor drains, sink drains, and garbage disposals, where organic debris and slimy films accumulate. Trash cans and recycling bins, particularly if not regularly emptied or cleaned, also attract phorid flies due to the presence of discarded food and organic waste.
Areas with persistent moisture from leaky plumbing or condensation offer suitable breeding grounds. These include spaces under sinks, behind appliances, in crawl spaces, or basements where water may collect. Uncleaned food preparation areas, rotting produce in pantries, or food spills in storage areas are additional hot spots. Phorid flies are also attracted to neglected pet waste or dead animal carcasses, such as rodents in wall voids.
Using Attractant Knowledge for Prevention
Controlling phorid flies involves addressing their attractants. Implementing consistent sanitation practices is a primary step. This includes regularly cleaning surfaces, promptly wiping up spills, and properly storing all food items in sealed containers. Disposing of decaying fruits, vegetables, and other organic waste quickly helps eliminate potential breeding sites.
Managing moisture is also important. Fixing any leaky pipes or faucets and ensuring proper drainage can prevent damp conditions. Regularly drying wet areas, such as condensation pans under refrigerators or air conditioners, also removes suitable breeding habitats. Proper waste management, including frequent emptying of trash cans and using sealed bins, reduces access to food sources. Sealing cracks and crevices in floors and walls can exclude flies and prevent access to hidden breeding sites.
