Why Are There So Many Small Black Flies in Your Kitchen?

If you’ve spotted many small black flies in your kitchen, it could be that you have food debris in your kitchen bin. These little pests find their way into homes through fruit and vegetables.

They usually breed in ripe flesh and skins of fruits and vegetables then lay their eggs on the food debris in your kitchen or compost bin. Thus, it would be best if you cleaned up your countertops after peeling fruits and vegetables to prevent attracting these tiny black pests.

Small Black Flies | Identification, Habitat, and Behavior

There are several types of flies that have a habit of invading kitchens. However, the most common are drain flies, fruit flies, phorid flies, and fungus gnats.

Drain Flies

Identification

Drain flies are moth-like flies that typically hang out around the drains. They commonly go by the nicknames moth flies or sink flies. They have a similar size to fruit flies and gnats—about 2 mm and 5 mm.

You can identify them with their round, fuzzy bodies and tiny, moth-like wings. Their colors also differ from other house flies, ranging from pale gray to black.

Although these pests look like moths, they’re not capable of flying far. You might notice them making large hops instead of buzzing around your kitchen like other pests.

Habitat

Drain flies love dirty water and get tiny amounts of bacteria and excrement. So, you can often find them gathering around in the following areas:

Kitchen and outdoor sinks

Septic tanks

Shower and bathtub drains

Sewers and basement sinks

Soil that holds sewage

If you pay attention closely, the common element in these places is the low, stagnant water. They lay eggs in the cover that forms within the pipes and drains when water accumulates sewage.

Thus, drain flies can also get drawn to:

Compost piles

Storm drains that contain standing water

Wet mops and buckets

Wet areas surrounding barns, garbage, and birdbaths

In homes, the most prevalent breeding sites are bathroom drains. Since these flies are weak fliers, you can often find them crawling on walls and other surfaces.

Behavior

These types of flies are most active at night and are weak flyers. Thus, they make short hopping efforts when they’re disturbed.

Drain flies can hatch up to 300 eggs in just 48 hours, but they can only last between 8 to 24 days. However, with the vastness and speed of their reproduction, they can cause significant infestation problems despite their short lifespan.

So, it’s crucial to deal with them right away before they speed through your pipes. They mainly consume organic materials found in standing water, like sewage.

Although they don’t bite people, animals, or structures damages, they could carry diseases due to their filthy roots. They can also be a great nuisance to homes, and their presence could be linked to a clogged drain.

Fruit Flies

Identification

Fruit flies are tiny, oval flies that stir and grow up to 1/8th of an inch in length. The color of their thorax is tan, while their abdomen is black. Furthermore, you can also identify them with the following characteristics:

Dark red eyes

Hairless wings and body

Their eyes can also be brownish-yellow to brownish-black

Once they reach adulthood, they’ll have a feathery bristle and antennae. In addition, fruit flies’ wings have thickened front margins intersected in two places.

Habitat

The habitat of fruit flies is a wide range. It includes homes, restaurants, supermarket stores, and places where food may be rotting and fermenting.

Fruit flies can enter your home if you buy fruits and vegetables, as well as bottled or jarred goods that aren’t properly sealed. They can also enter houses through open windows, doors, or within the gaps in your exterior doors or windows.

In addition, they’re also attracted to gardens, compost piles, and trash bins that aren’t tightly closed.

Behavior

Fruit flies can lay up to 500 eggs. Thus, it’s best to limit their access to food sources to prevent severe infestation problems.

In terms of food consumption, they feed on rotten fruits, vegetables, and other organic items. They can also be seen hovering around over convenient sugar sources.

Most fruit fly populations can be found indoors where food sources are abundant. This type of situation makes them active year-round and feed on your displayed overripe fruits and vegetables or other decaying matter in your place.

Phorid Flies

Identification

Phorid flies have the same appearance as fruit flies. Their color ranges from black, dull brown, to yellow.

You can also identify them with their arched thorax which gives them a humpbacked appearance. This is why they’re often called “humpbacked flies.”

They’re about 0.5 mm to 5.5 mm long and are weak fliers. They can be seen walking quickly across surfaces rather than flying. Phorid larvae possess a shiny black head and a long, whitish-to-clear, legless body.

Habitat

Phorid flies are often seen running across tables, TV screens, walls, and plant foliage. They breed rapidly in rotting organic matter, corpses, and fungi. This is why they’re also called “scuttle flies,” “coffin flies,” and in some places, “sewer flies.”

Indoors, they can be seen breeding in the following places:

Crawl spaces

Dumpster

Recycle bins

Garbage disposals

Trash containers

Drains

Grease traps

Rotting produce

They can also be found in places where moist organic matter can accumulate. These flies are common in residential areas and commercial facilities where food is prepared and served. Furthermore, they can also be found in hospitals and food warehouses.

Behavior

The female phorid flies can lay as many as 700 eggs in the 25 days of their life cycle. They choose their hosts by doing an ambush or through an active searching strategy.

They feed on decomposing plant and animal matter, including sewage and household organic waste. Unlike fruit flies, they don’t like the smell of vinegar.

Fungus Gnats

Identification

You can identify fungus gnats with their slender legs and segmented antennae, which are longer than their heads. They have a dark and delicate look, having the same appearance as mosquitoes.

Adult fungus gnats are about 1/8 to 1/16 of an inch long, with light gray to clear wings. These pests are relatively small but are easy to recognize.

Although these gnats can fly, they tend to hop from one place to another when they’re in the soil.

Habitat

Fungus gnats may inhabit your indoor houseplants. They also infest oil, potting mix, and other organic decomposition sources.

These pests often reside in potted plants and across compost, growing media, foliage, and wet mulch piles.

Behavior

Fungus gnats are attracted to light. Thus, you might frequently see them near your windows indoors.

Moreover, these pests don’t usually move too much since they’re not good fliers. They lay their tiny eggs in potting soil or moist organic debris.

They usually feed on grass clippings, leaf mold, organic mulch, compost, fungi, and root hairs in terms of food. This is why fungus gnats can be a problem in greenhouses, nurseries, and potted plants.
