There is only one permanent solution to this type of small fly infestation - the broken pipe has to be located and replaced.Repetitive outbreaks of small, humpbacked flies in a home, restaurant or hospital may mean serious trouble underground. Why underground? Because one of the common sources of phorid flies (also called humpbacked flies or coffin flies) is a broken sewer line oozing goo under a building.Phorid fly adults are tiny, and most are brownish-yellow with brown wings, a small head and a large, humped thorax. Adults are reluctant to fly and often run instead. Larvae are whitish and wormlike, and feed on sewage, dead animals, human corpses (underground and in mausoleums), animal feces, rotting plants and have been found infesting open wounds in hospitals.
