Facts, Identification, and Control

Below are some facts about Phorid flies

Latin Name

Family Phoridae


Phorid flies are about an eighth inch in size. Most have a dull brown color, although this depends on the species. Unlike fruit flies that have bright red eyes, Phorid flies have dark and dull-colored eyes.

Look at pictures of phorid flies and you’ll notice a hump on their thorax, that’s why they are also known as Phorid humpbacked flies. They also prefer to run and walk on surfaces instead of flying.

Facts about Phorid Flies

Phorid flies reproduce quickly as one female can lay 40 eggs within 12 hours. The egg hatches into larvae.

Phorid fly larvae are about 10 millimeters in length and have a spindle shape. Most have a light yellow or white color.

The adult female lays eggs on decaying organic matter like rotting foods, animal carcass, sewage, or the drain film.

The larvae develop into immature insects that feed on organic matter. Some species lay eggs in the nests of wasps, bees, ants, and termites. All flies spend about sixteen days in the larval phase of development.

Where Do They Live?

Phorid flies can breed in any material. You can find them breeding in rotting produce, dumpsters, trash containers, drains, crawlspaces, grease traps, and recycle bins. You can also find them where there’s moist organic matter.

What Do They Eat?

These flies feed on decaying organic matter. The Phorid flies also consume rotting meat, sewage, decomposing fruits, and dead animal carcasses.

They can also consume fungi and organic debris that forms in soiled drains and trash receptacles.

How Did I Get Phorid Flies?

You may have a Phorid humpbacked fly infestation if you have a damaged or clogged drain. These flies may also be attracted to overwatered potted plant soils, dirty garbage containers, and sewer pipes.

Phorid flies like decaying organic matter, and you can get them if you have any decaying items in your house or around the yard.

How serious are Phorid Flies?

Phorid flies breed and feed on decaying matter. That means there’s a high risk of them spreading diseases to humans. These flies also breed quickly as one female can lay up to 700 eggs, something that would lead to exponential growth. You may need an integrated pest control plan to handle a Phorid fly infestation.

Having an infestation can be bothersome and unsightly as these pests reproduce at a fast rate.

What Can I Do About Phorid Flies?

If you’ve noticed Phorid flies around your kitchen, you need to clean out the countertops to remove any spills and food crumbs. Check under the garbage to see if there are any spills.

Throw away spoiled fruits and vegetables. Cover all food items in sealed containers. Don’t forget to repair any leaky pipes or plumbing systems that could be creating a moist environment for these flies.

Moreover, these flies are attracted to light, which means they gravitate towards sources of illumination like lamps.
