Drain Flies 101: Identifying, Preventing, and Eliminating Those Pesky Bathroom Bugs

Have you ever spotted tiny, moth-like insects flitting around your bathroom, or worse, hovering around your face while you’re trying to brush your teeth or take your morning shower? 

Those annoying little critters have a name: they are none other than drain flies, also known as moth flies or sewer gnats. 

Despite their cute-sounding names, these pests are a major nuisance, flitting around our personal spaces and even laying eggs in our drains and pipes. 

Want to get rid of drain flies for good? It all starts with understanding these pests and taking steps to prevent them. Let’s get started.

Identifying Drain Flies

Drain flies, also known as moth flies, are a common sight in many homes. They are tiny insects, measuring about 1/8 inch in length, and have a fuzzy appearance due to their body and wings being covered in small hairs. Drain flies have three pairs of legs and two wings on their body, which are covered in a unique pattern of gray and black spots.

You might spot these winged creatures near moist environments, such as near the sink, shower, or bathtub. They are often found near drains due to their need for moisture and organic matter. These flies usually breed in stagnant water or in decaying organic matter, such as inside drain pipes, a sink trap, or a dirty garbage disposal.

One common misconception about drain flies is that they are fruit flies or gnats. However, there are key differences between these pests. Fruit flies, for instance, are slightly larger than drain flies, most commonly will have red eyes, and are attracted to overripe or rotting fruit. Gnats, on the other hand, are typically found near potted plants and carry a distinct buzzing sound.

It’s no secret that dealing with drain flies can be frustrating. While they aren’t harmful to humans, they can still be a nuisance, ruining the cleanliness of your home and making it uncomfortable for you and your family.

Understanding Drain Fly Habits

Drain flies typically have a lifespan of two to three weeks. Their life cycle has four stages: egg, larva, pupa, and adult.

Females lay their eggs in moist areas, such as sink drains, where organic matter is present. The eggs hatch into larvae, which feed on organic material until they reach the pupa stage. After a few days, the pupae emerge as adult drain flies.

Again, these flies are attracted to damp areas, particularly those with decaying organic matter. This includes sink drains, standing water, and compost piles. These insects can breed quickly in these environments and create large populations within a short period.

Preventing Drain Fly Infestations

Drain flies might seem harmless, but their infestations can quickly turn your home or apartment into what feels like a full-blown horror movie.

So how do you keep them away?

First, keep your drains clean and clear. Remember, drain flies thrive in damp, dirty places, so make sure you frequently clean your drains with a combination of vinegar and baking soda and don’t forget the underside of the garbage disposal splash guard. This will break up any clogs and eliminate any sludge that might be attracting drain flies.

Keeping your pipes in good working order is another essential step in avoiding drain fly infestations. Fix any leaky faucets or pipes, and make sure your plumbing is up to code. Any standing water is an invitation for these pesky little critters to lay their eggs.

Eliminating Drain Fly Infestations to Take Back Your Space

If you’re dealing with a larger infestation and the remedies described above just don’t work, it may be time to bust out something a little stronger. Commercial drain cleaners can be effective, especially when used with a hard bristle brush. You may have to snake the drain first to remove any buildup of organic matter. 

Generally, insecticides are not usually necessary for drain fly management. But if you’re having trouble dealing with an infestation, it’s important to know when to turn in the towel and call in the professionals. Pest control services have the know-how and tools to handle even the toughest drain fly situations.
