How to Identify Blow Fly Infestation

If you notice blow flies in your house all of a sudden, and they’re hard to miss because of the loud buzzing sounds they make, chances are, there may be a dead animal nearby. If you have a dead animal under your house or in your home, you will most likely be alerted by the smell of rotting flesh as well. Slightly larger than true houseflies, blow flies are metallic green, blue-orange or black in color. They are adult forms of maggots that might be infesting a dead bird or small animal in your yard or rotting meat in your garbage can or compost pile.

How can Blow Flies Affect Humans?

Adult blow flies create a plethora of disease potentials for humans, as they fly from dung and/or carrion to trash to your food. Blow flies are responsible for carrying the bacteria that causes dysentery, typhus, and cholera.
