text: how do you get rid of phorid flies? i have had these guys in my home for over a month now i've tried the foam drain cleaners, the exterminater doesn't know.  i've cleaned under the fridge the drian overflowes everything, i've fogged the house yet they're still here.  does anyone have any suggestions? i'm sure you're aware that you have to find their breeding site. once the site is found it must be thoroughly scraped, cleaned, and dried.   the locations vary widely, but are usually associated with rotting fruit, vegetables or meat, wet organic soil, potted plants, cut flowers, garbage disposals, pet cages and floor drains.   large infestations of these flies are often the result of broken drains or garbage disposals that allow organic matter to accumulate in out-of-the-way places such as wall voids, under floors, in basements, or in the soil of crawl spaces. phorid flies often serve as an indicator of a broken sewage line. as organic-rich waste-water passes through a damaged line, some of the solution seeps into surrounding soil. this can provide the perfect breeding ground for phorid flies. if you have an ongoing phorid fly problem, consider having the sewage lines inspected for leaks and repaired as needed
