Blow fly

Black garbage flies are 1/5″ long little, thin, black, glossy insects. Going by the name, garbage flies feed on anything found in the dumpster or any dead or decaying food matter.

Gnat fly

These flies are around 2.5 millimeters long, while some species can grow to reach as large as 5.1 millimeters. Their hue ranges from yellowish to black, and nearly all species have crimson eyes.

Gnats are a widespread irritation everywhere there is food. Because these flies like to deposit their eggs on decomposing organic debris, they frequently contaminate food. While they are a problem in agriculture, they are also a nuisance in the house.

Adult drain flies are tiny (1/16 to 1/5 in, 2 to 5 mm), brownish in color, and thickly haired. When asleep, they keep their large wings flat or like a canopy over their bodies. Drain flies consume algae, bacteria, fungus, and other tiny creatures found in the film.

It is frequently found on the walls of toilets, showers, and washrooms. The dark, worm-like larva grows in organic muck that collects in small puddles and tree holes outside. Indoors, it may grow in sink traps, drains, and dead-flow regions of domestic plumbing.

Stable flies deserve special note since both sexes feed on the blood of animals, including people, and frequently bite around the ankles. Females deposit their eggs in decomposing straw and dung and damp mounds of animal feed and yard garbage.
