- Color: tan, brown, or black.
- Size: small, 1/64 to 1/4 inch.
- Possess a “humpbacked” appearance, with a large thorax and very small head.
- Distinctive habit of running in fast movements punctuated by sudden stops.
Habits of Phorid Flies:
- Females deposit eggs in batches of up to 20.
- A complete life cycle can occur in as little as 14-37 days.
- Typical breeding sites include food residues in trash cans, deposits of decaying organic matter in cracks and crevices, and drain pipes.
- Development can also occur in a broad range of other sites, including carrion, over-watered potted plants, unused garbage disposals, dirty mops, grease traps, and animal cages.
Damage From Phorid Flies:
- Due to their habit of breeding in unsanitary conditions, phorid flies may spread bacteria to other surfaces.
- The potential for rapid growth in hidden breeding sites may lead to large nuisance populations.
- Any organic material that stays consistently moist. This includes cracks between kitchen tiles, wet floor mops, and organic deposits in drain pipes.
How to Control and Kill Phorid Flies:
- The breeding sites must be eliminated to control phorid fly populations.
- Clean away all organic debris, even small deposits in cracks and crevices.
- Unusual breeding sites, such as dirty mops should also be cleaned and dried to disrupt the phord fly life cycle.
- Broken sewer lines below ground may also need to be fixed to achieve control.
