Noticed tiny flies hovering near your sink or drain? Those aren’t regular fruit flies—they’re likely drain fly or sewer fly invaders. And once they show up, they multiply fast.
This blog breaks down exactly how to get rid of drain flies, what causes them, and how to stop the swarm for good. We’ll cover DIY steps, signs of bigger issues, and when it’s time to call in the pros. Let’s shut down their party before it gets worse.
What Are These Pesky Drain & Sewer Flies?
Sink flies, drain flies, and sewer flies are tiny, fuzzy insects that love moist, organic gunk inside your drains. They lay their eggs in that gunk, which hatches into sewer fly larvae—and soon, you’ve got a full-on invasion.
So, what causes sewer flies? Think rotting food, standing water, grease buildup, or even small leaks. They’re often a sign of kitchen sink plumbing problems, but they can also show up in tubs, showers, and basement drains.
Your Drain Flies Treatment: A DIY Guide
Here’s how to remove drain flies and keep them from coming back:
Step 1: Clean the Drain Thoroughly
Use a pipe brush or old toothbrush to scrub the inside of your drain. This removes the buildup where flies lay eggs.
Step 2: Use a Natural or Commercial Drain Fly Killer
Pour boiling water, followed by baking soda and vinegar, or use a store-bought drain fly killer. Do this daily for several days to break the life cycle. Wondering, will bleach kill drain flies? Sometimes, but it’s not always the most effective method.
Step 3: Trap the Adults
Set a shallow dish of apple cider vinegar and dish soap near the drain. It lures the adult flies and drowns them—simple and satisfying.
Step 4: Check for Hidden Plumbing Issues
A stubborn sewer fly infestation can point to a deeper issue like roots in the sewer line or pipe cracks. Persistent problems often need more than surface-level cleaning.
Step 5: Keep It Clean
Prevent future fly visits by flushing drains weekly, avoiding food scraps in sinks, and scheduling grease tank cleaning if you have a larger plumbing setup.
When Let the Experts Eradicate Drain Flies
Seeing small flies in bathroom drains and kitchen sinks? That’s a red flag. When they show up in more than one place, it usually means the problem runs deeper than surface gunk. You could be dealing with hidden leaks, decaying organic buildup inside walls, or even issues further down your plumbing system.
Pros can inspect pipes, fix clogged drains, and find hidden damage. Plus, they’ll help you spot early signs before a small swarm turns into a health hazard—or a full-on infestation hiding behind an issue.
