How to Identify Bottle Fly Infestations

Not known to come indoors, adult bottle flies in your home generally indicate a breeding source nearby. Larger than true houseflies, bottle flies, with their distinctive, shiny, green, blue and black metallic bodies emit loud, noticeable buzzing sounds in flight. The bottle flies buzzing around your home are young adult bottle flies and may also be accompanied by the foul odor of dead animal matter.

From dead random wildlife in the walls, attic or under your home to mishandled food scraps, especially meat scraps in outdoor receptacles, locating and removing dead animal matter is important in controlling bottle fly infestations.

Growing up in dead animal matter, maggots emerge as adult bottle flies that land in sewage, dung and other disease-ridden materials before sometimes landing in your food. Bottle flies transmit diseases and human pathogens; they are responsible for dysentery, typhus and cholera outbreaks.
