Getting Rid of Drain Flies in 6 Simple Steps

January 16, 2015

Drain flies are a nuisance that pop up in many homes. They’re small winged insects that look similar to moths. Though they may seem harmless, they can transfer harmful bacteria from your drains that cause illnesses such as enteric fever, cholera, dysentery, hepatitis, conjunctivitis, poliomyelitis and tuberculosis.

Drain flies are commonly found in places with shallow, stagnant water, such as kitchens, bathrooms and basements. This makes drains one of their most common habitats, however they are also found in sewers, septic tanks and soil that has been contaminated with sewage.

how to get rid of drain flies

Here’s how to determine if you have a drain fly problem and how to get rid of them:

  1. Identify the Source
    If you have multiple drains in your home, determining which drains are home to drain flies is the first step to getting rid of them. To do this, simply cover part of the drain with clear tape. Make sure you don’t block the entire drain, as this may cause additional problems. Check back in a day or two. Drains that have drain flies in residence will have flies stuck to the tape.
  2. Clean Out the Drain Filter
    Drain flies lay their eggs in the debris that gets caught in your drains. One pair of drain flies can result in a population of up to a million drain flies within 6-8 weeks, so keeping on top of cleaning your drains is essential to stymie the problem. Clean out any areas where they could possibly lay eggs and breed is the first step to getting rid of drain flies. Clean our any hair or other gunk that is caught in the filter.
  3. Use a Pipe Brush
    A pipe brush is a specialized instrument meant to clean out debris that lingers in pipes in areas where you can’t reach. If you don’t have one, any narrow brush will do, to clean the sides of the pipe where debris may be caught. A plumbing snake can also be used, though it won’t allow you to scrub the sides of the pipe to remove any debris that might be caught there.
  4. Follow Up With Gel Cleaner
    After you manage to scrub away all the large debris you can reach, a gel cleaner will help you get rid of any remaining debris that is left in the drain. Using a gel cleaner is important, as gel drain cleaners are intended to get rid of organic matter that is caught in your drain. This eliminates the breeding grounds used by drain flies. Don’t use a foam or liquid drain cleaner, as they won’t be as effective.
  5. Flush Out the Area With Water
    After you’ve let the gel cleaner sit for a few hours (follow the drain cleaner directions) flush out the drain with warm water. This should flush out all of the remaining drain cleaner and any leftover debris where drain flies could hide and lay their eggs.
  6. Maintain, Maintain, Maintain!
    The key to getting rid of drain flies and keeping them away is to maintain all the drains in your home. Ideally, you should clean out all the drains in your home about once a month. If you spot signs of drain flies in your home, take action immediately to prevent the problem from worsening.
