Appearance, Behavior, and Flies
Bottle flies belong to the family Calliphoridae and are larger than common house flies. They are attracted to rotting and decayed organic matter, mostly meat. Bottle flies are the first insects that settle on a dead body. These flies also lay eggs (that become maggots) into live wounds of animals and humans. Bottle flies also sometimes feed on flowers and plants.
Bottle flies require meat (as it contains particular proteins) to lay eggs. They are also attracted to garbage and decomposing food. These poikilothermic pests breed usually in the summer but can withstand all climates and conditions.
To know whether or not you have a bottle fly infestation in your house, count for how many flies you see. Bottle flies often travel in groups. The more the number of flies, the higher the chance there is of an infestation. Look out for their maggots as well. Check areas that are moist or filthy – if there are bottle flies in your house, they will flock there.
