| Any freshly decaying, moist organic matter that sits undisturbed for five or more days. Usually associated with fresh fruits and vegetables stored at room temperatures. Once inside, adult flies emerging from a piece of infested fruit can find and exploit other potential breeding sites such as poorly maintained trash containers, recycling bins, food kicked underneath tables, coolers, etc., and garbage disposals. They also may be found breeding in dumpsters outside and flying to and entering the building through doorways. The breeding media must be continually moist for the larvae to develop and generally in a fairly fresh state of decay. Any crack or area where organic matter can accumulate can support these flies. |
