Behavior and Habitat of Drain Flies

Drain flies prefer a damp and organic environment, and are often found near drains, sewage systems, and other moisture-rich habitats. These flies lay their eggs in standing water or in the film that can develop on the inner surfaces of drains. Their larvae feed on the organic matter present in these locations, including decaying vegetation and trapped debris. Drain flies are primarily nocturnal and are most active during the evening. They are not known to bite or transmit diseases, but their presence can be a nuisance when they infest homes.

Signs of Infestation of Drain Flies

Signs of a drain fly infestation typically include the following: 

  • Musty odor: An unpleasant, musty odor can accompany a drain fly infestation, especially when their breeding sites contain decaying matter.
  • Adult flies: The most obvious sign is the presence of adult drain flies, which you may notice flying around drains, sinks, or other moist areas, especially during the evening.
  • Larvae or worms: Drain fly larvae may be seen wriggling in the sludge inside drains or near breeding sites like standing water.
  • Visual clusters: Adult drain flies often cluster together, especially on walls and ceilings near breeding sites, making them more noticeable.

Tips for Prevention of Drain Flies

Preventing drain fly infestations primarily involves eliminating their preferred breeding grounds and maintaining good sanitation practices. A few helpful tips you can follow to prevent the presence of drain flies in your home include regularly cleaning your drains, fixing any leaks or water seepage promptly, installing drain covers or screens, wiping drains dry after use, sealing cracks and gaps around plumbing fixtures, and regularly cleaning your bathrooms and kitchen.

 

Getting Rid of Drain Flies

To get rid of drain flies, start by identifying breeding sites in drains, pipes, or standing water. Installing drain covers and fixing plumbing leaks are also good practices for keeping the drain flies away. Finally, you should wipe dry sinks, tubs, and showers after use to keep them from attracting drain flies and dispose of all food scraps properly.
