Bottle Fly Infestation

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.

Bottle flies detrimental to human health
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 flies. 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.

Bottle flies indoors may indicate a rodent infestation
In a worst case scenario, adult bottle flies indoors can indicate a rodent infestation, as DIY rodent control methods can result in rodent carcasses decomposing in hard to reach places, such as wall voids. Controlling adult bottle flies and/or locating dead animals in your home should be left to professional pest control companies, such as Truly Nolen, who can inspect your home and determine the safest and least invasive plan of control for your specific pest control situation.
