How to Get Rid of Sewer Flies in Your Lubbock Home

Do you have annoying, fuzzy, moth-like bugs hanging out near your sink or shower drain? If so, you’ve probably met the drain fly, also known as the sewer fly.

They might look harmless at first, but they are definitely uninvited pests. In this blog, we’re diving into where these little guys come from and how you can reclaim your bathroom and Lubbock home.

What Exactly Are Sewer Flies?

Drain flies are tiny insects that love moisture. They don’t fly very well, so they mostly hop and crawl around, which is why you usually find them right next to your drains. 

The reason they’re hanging out in your pipes isn’t just for the water; it’s for the organic film, which is basically a layer of slime and gunk that builds up inside your plumbing. They lay their eggs in that slime, and before you know it, you have a full-on infestation.

Where Are They Coming From?

In West Texas, our plumbing works hard. Sewer flies usually show up because of:

  • Clogged Drains: Hair, soap scum, and food particles create the perfect nesting material for these creatures.
  • Unused Sinks: If you have a guest bathroom you rarely use, the water in the “P-trap” dries up, allowing sewer gases and flies to crawl right up.
  • Sewer Line Issues: Sometimes, the problem is deeper than your sink. Cracks in your main line can attract them from under your house.

DIY Tips to Get Rid of Them

If you only see one or two flies, you might be able to handle it yourself with these steps:

  1. The Tape Test: Cover your drain with a piece of clear tape overnight (don’t seal it completely). If you wake up and flies are stuck to the bottom, you’ve found their home.
  2. Clean the Rim: Use a stiff pipe brush to scrub the inside of the drain. Removing that slimy buildup is the only way to stop them from breeding.
  3. Boiling Water: Pouring boiling water down the drain can sometimes kill the larvae, but it usually isn’t a permanent fix if the gunk stays behind.

Pro-tip: Avoid using harsh chemical cleaners. They can actually damage your pipes over time and often don’t reach the root of the fly problem.

When DIY Isn’t Enough

If you’ve scrubbed, poured, and taped, but the flies keep coming back, it’s a sign of a bigger issue. This is where we see most homeowners get frustrated. The truth is, household cleaners can’t reach deep into your system. If there is a major blockage or a break in your pipes, those flies will keep multiplying, no matter how much boiling water you use.
