How to Get Rid of Phorid Flies
Phorid flies are tiny flying insects and may be a tan or dark color. The thorax has a distinguishable arch shape giving it the nickname 'humpbacked fly'. The phorid fly has dark eyes (unlike the red eyes of the fruit fly) and will usually scuttle around countertops to get a running start before taking off in flight. They are also called coffin flies because their numbers increase around morturaries. Because of the unsanitary locations they thrive in, they are potential vectors of deadly disease.
Phorid flies can easily become stable in kitchens, bathrooms, and food processing facilities. Like other insects, they feed on decaying organic matter and fungi. They prefer moist environments and will breed in drains, trashcans, and dead animals. Many restaurants will mop on a daily basis – over time, the grout and tile may crack allowing moisture and organic debris to get caught under the slab. In homes, overwatered house plants and garbage disposals represent perfect breeding grounds. Phorid flies tend to lay their eggs in drains.
The phorid fly is easily controlled through increased sanitation. Severe phorid fly infestations may indicate a dead animal trapped within the structure (such as a rat or mouse), or even a faulty septic system.
- Check to make sure there are no leaks. Phorid flies need moisture to survive. Defective plumbing or water damage is an invitation for fly populations.
- Clean up after yourself. Drains should be cleaned, garbage bins washed, and garbage disposal emptied. Keep exposed food items sealed in a container or refrigerated. Scrub the drain with a metal brush if possible.
- Check potted plants and flowers. Water standing in a pot or moist soil could be the source of your phorid infestation. Inspect any flowers in vases as well.
- Mop laminate or tile floors. Preferred product is any biodegradable mopping foam designed to eliminate any debris caught in the grout cracks or peeling laminate, but soap and water will generally get the job done. Dirty mop heads should be sterilized or replaced.
Drains can be cleaned with boiling water or a combination of white vinegar and baking soda. Plants that require heavy watering should be temporarily placed elsewhere.
Pesticides should be avoided in phorid fly programs and efforts should focus on eliminating the source of the problem. It's illegal to use pesticides in drains, so filth and bacteria caught in drains must be removed for total control. If the problem persists, consult a mold specialist and have the home inspected. There are many companies willing to do this free of charge.
