How to Identify and Eliminate Drain Moths in Your Home

Drain moths, also known as sewer flies or sink flies, are tiny pests that thrive in damp, organic-rich environments like drains and sewage systems. While they are not harmful, a drain moth infestation can be frustrating and unsanitary.

If you’ve noticed these tiny, fuzzy-winged insects hovering around your sinks or showers, it’s time to take action. Here’s a step-by-step guide on how to identify and eliminate drain moths effectively.

• Enzyme-based drain cleaner

• Dish soap or Apple cider vinegar

• Fly traps

• Drain gel treatment

• Baking Soda
• Boiling Water

Identify Drain Moth Infestation

Before taking action, confirm that you have a drain moth problem by looking for these signs:

• Small, fuzzy-winged flies hovering near drains.
• Larvae in sink or shower drains, appearing as tiny worms.
• Slow drainage and foul odors from organic build-up.

Flush Drains with Boiling Water

• Pour a pot of boiling water down the affected drain to kill larvae and flush out debris.
• Repeat this daily for several days to disrupt their breeding cycle.

Deep Clean the Drain

• Use a drain brush to scrub the inside of the drain and remove organic build-up.
• Apply a baking soda and vinegar solution to break down residue. Let it sit for 15 minutes, then rinse with hot water.
• Use an enzyme-based drain cleaner to target organic matter deep within the pipes.

Apply Drain Gel and Prevent Future Infestations

• Use a bio-enzymatic drain gel treatment to eliminate organic residue and prevent drain moths from returning.
• Regularly clean drains, fix leaks, and keep pipes dry to discourage infestations.
• Cover drains with mesh strainers to prevent build-up of organic material.
