Drain flies might look harmless, but their larvae are a hidden problem in many homes. Found in drains and pipes, drain fly larvae thrive in damp areas filled with organic debris. Not only are these drain fly larvae worms unpleasant to discover, but they can also lead to health concerns. This blog will guide you through everything you need to know, from identifying these pesky creatures to getting rid of them effectively.
What Are Drain Fly Larvae?
Drain fly larvae are the immature form of drain flies, also called moth flies. You’ll find them in wet, slimy places like sink pipes and shower drains.
Appearance
These larvae look like tiny worms. They are usually white or cream-colored with segmented bodies. At one end, they have a small breathing tube, which lets them get air while they’re covered in organic matter. They typically grow up to 9mm in length.
Habitat
Drain fly larvae thrive in places with moisture and food. Their favorite spots are the slimy layers of grime found inside pipes. They will also live in damp areas with standing water, such as shower drains, sink traps, and even sewer systems.
Life Cycle
Drain flies go through several stages:
- Egg Stage – A female drain fly lays up to 100 eggs in slimy buildup inside a drain.
- Larva Stage – Eggs hatch into larvae in just 1–2 days. These larvae, also known as drain worms, feed on bacteria and decaying organic material.
- Pupal Stage – After about 10–15 days, larvae form a pupa. This stage lasts 1–2 days.
- Adult Stage – Adult flies emerge and live for about two weeks. The cycle repeats quickly, turning small infestations into much bigger problems.Â

Why Are Drain Fly Larvae a Problem?
Many people don’t realize they have a problem with drain fly larvae until it becomes severe. These worms can cause both health and hygiene issues.
Spread of Bacteria
The buildup they live in contains bacteria, which can be spread to other parts of your home. If these flies make their way to food preparation areas, they could contaminate your food.
Worsen Allergies and Asthma
Dead drain flies and larvae can dry out and become part of the dust in your home. Breathing this, especially for people with asthma or allergies, can trigger symptoms or make them worse.
Persistent Infestations
Because of their short life cycle, drain flies multiply fast. If the larvae are not dealt with, adult flies will keep reappearing, week after week. Read also the post on Do Fruit Flies Bite: How to Identify and Get Rid of Them at House

How to Get Rid of Drain Fly Larvae
Removing drain fly larvae worms doesn’t have to be difficult. With some simple tools and steps, you can stop them from coming back.
Step 1: Clean the Drains
Start by identifying where the larvae are. The most likely spots are slow or clogged drains. Use a stiff brush to scrub the drain walls and remove the slime.
- Remove the drain cover.
- Scrub the inside of the drain with a stiff brush.
- Pour hot water to rinse away any loose debris.
Step 2: Use Enzymatic Cleaners
Enzyme-based cleaners are very effective for dislodging organic matter that larvae feed on. Pour the cleaner according to the product instructions and allow it to work overnight. Repeat if necessary.
Step 3: Flush with Hot Water
While boiling water is often suggested, use caution. Very hot water can help kill drain fly larvae, but boiling water can also damage older pipes. Pour the hot water down the cleaned drain to remove any remaining debris.
Step 4: Seal Cracks and Gaps
Cracks in pipes or drains provide entry points for flies to lay their eggs. Seal these using waterproof sealant or call a plumber to fix damaged pipes.
Step 5: Call a Professional
If the problem persists, reach out to a pest control professional or plumber. They have advanced tools and treatments to clear infestations and check for serious issues like sewer leaks. Our Latest post Flying Ants vs Termites: Appearance, Behavior & Life Cycle Differences
