Bluebottle Fly

Bluebottle Flies are metallic blue or green in color. They range in size from ¼- to 3/8-inch in length.


Gross smells attract adult bluebottle flies. The smell is a sign that tells them something is rotting away. Bluebottle flies are also attracted to buildings by food odors or warm/cool air currents coming through cracks around doors and windows.

They lay eggs in dead animals, feces, any rotting organic matter.

The eggs will soon (2-3 days) hatch into bluebottle fly maggots. They will start eating their way out and will be fully grown in about three days. The maggots then hide in the soil or somewhere else dark and with high humidity, like inside your bin or under the kitchen sink. The maggots will pupate into cocoons. After two weeks, your brand-new batch of bluebottle flies would be ready to cause trouble.


Bottle flies feed on a variety of food materials but prefer fermenting or decaying organic matter.


Fly control is challenging. Keep doors and windows closed unless they are equipped with a tight-fitting screen. Throw trash away in trash cans in plastic bags, and locate trash receptacles as far from the building as possible. Bluebottle flies carry bacteria. The presence of Bluebottle flies in your property bares some health risks, action must be taken swiftly. Install fly traps around your home and don’t leave food with no cover on top, at least till you limit the population of the flies.
