How to Get Rid of Drain Flies (Sewer Flies) Fast

Drain flies in your kitchen or bathroom can turn a clean home into a frustrating problem fast. You notice tiny flies hovering around your sink, swat at them, and they keep coming back within minutes. Even after scrubbing your house clean, they still return.

If this sounds familiar, you are likely dealing with drain flies, one of the most common issues homeowners face in the Sacramento region.

These little menaces are not just annoying; they are often a sign that organic buildup and moisture are present somewhere in or around your drainage system.

Understanding what attracts drain flies is the first step to getting rid of them. So, how do you get rid of sewer flies? In this blog, we will share the best tips to keep your residence fly-free.

How to Get Rid of Sewer Flies for Good?

Here are the steps to eliminate drain flies and help keep them from coming back:

Step 1: Identify All Potential Breeding Sites

• Inspect every drain, including all the sinks, shower drains, and floor drains across your property.
• Don't miss overlooked areas such as:
  • Basement or utility room floor drains
  • Garage and laundry room drains

Step 2: Physically Clean Each Drain

• Remove the cover
• Scrub the interior using a stiff pipe brush to scrape away the slimy film.
• Reach deeper with a drain snake to clear the pipe.

Step 3: Apply an Enzymatic Drain Cleaner

• An enzyme-based or biological drain treatment may help break down remaining organic residue.
• Follow the product instructions carefully and use a product that is compatible with your plumbing system.
• Practice follow-up treatment to avoid future infestations.

Step 4: Fix Underlying Plumbing Issues

• Stagnant pipes and standing water are perfect conditions for organic matter to accumulate.
• Repair leaky pipes and ensure proper water flow to eliminate the moist environments that attract drain flies.

Other Ways to Get Rid of Drain Flies Right Now

Having the flies buzzing back can be quite annoying; however, there are a few other DIY treatments that are effective against them.

1. If you have metal pipes, you can pour boiling water down the drain to help loosen and wash away surface residue. Repeat the process once or twice a day for several days for best results. Do not use this method with PVC pipes. However, if drain flies keep coming back, cleaning the inside of the drain and trap can help remove the buildup where they breed.
2. Another method you can try is to pour half a cup of baking soda, half a cup of salt, and one cup of Vinegar down the drain. Allow the mixture to sit overnight so that the foam breaks down the organic buildup where the flies are breeding. Pour boiling water down the drain in the morning after completing the treatment.
3. The third method is to create a simple trap. Take a bowl with apple cider vinegar and a few drops of dish soap. Cover the bowl with plastic wrap and make small holes in it. As the flies are attracted to the vinegar, they fly in and get trapped by the soap.

NOTE: These are temporary solutions and do not eliminate the breeding environment. For permanent results, professional intervention is required, along with ongoing routine maintenance to prevent recurring infestations.

How Can I Prevent Drain Flies from Coming Back in the Future?

Prevention is always better than the hassle of elimination. Practice simple habits every day to prevent drain flies from returning.

• Running hot water down the drain at least once a week flushes away the organic matter that the flies breed on.
• Secondly, cleaning the drain once a month with baking soda and vinegar, as mentioned previously, also helps.
• Using enzymatic drain cleaners on a regular basis makes all the difference, as they are safe for plumbing and break down the organic buildup that attracts drain flies. This method is all the more relevant to restaurant and food service businesses with high-volume drains in the Sacramento areas.
• Fixing plumbing leaks immediately controls the moisture buildup that the flies thrive on, especially in the older Sacramento homes with aging plumbing systems.
• Establishing a regular drain maintenance schedule is important because it helps prevent drain fly infestations from becoming severe.

Quick Queries From Our Clients

Why Do Drain Flies Keep Coming Back No Matter What I Try?

Most treatments kill adult flies but leave the eggs and larvae behind. Drain flies can keep coming back if organic buildup remains inside the pipes. A hidden leak, broken pipe, or missed drain can also be the source, especially in older Sacramento homes. Thoroughly cleaning the affected drain and fixing any plumbing issues can help break the cycle.

Can Drain Flies Cause Health Problems?

Drain flies are mainly a nuisance and do not directly spread disease. However, they can pick up bacteria from organic waste and spread them to other areas. Their body hairs may also irritate the respiratory system, which can be a concern for people with allergies or asthma. In restaurants, visible drain flies can also raise concerns about cleanliness. Cleaning the drain and removing the buildup where they breed can help reduce the problem.

Are drain flies a sign of a bigger plumbing problem?

Drain flies usually indicate a moist area with organic buildup somewhere in or around your drainage system. In some cases, the source may be a clogged or dirty drain. In others, standing water, a slow drain, a leak, or an overlooked drain may be contributing to the infestation. Such issues are prevalent in Sacramento homes because they have older plumbing systems.

Homeowners should call a plumber if the flies keep coming back or if they notice slow drains, odors, or other signs of a deeper issue. A Professional plumber can use camera inspection to find issues that are not visible from the surface.

What is the difference between a drain fly and a sewer fly?

“Drain fly,” “sewer fly,” “moth fly,” and “sink fly” all refer to the same insect. These common names are used for small flies in the family Psychodidae. While the different names can be confusing, they point to the same problem and require the same solution.

Can I use bleach to kill drain flies?

Bleach may help eliminate drain flies, but it does not remove the organic buildup where the larvae breed. Enzymatic cleaners are the best option, especially in Sacramento homes with aging plumbing systems.

Why do I see drain flies in winter?

Drain flies live and breed inside pipes, so cold weather does not eliminate them. In winter, they may become even more noticeable because windows and doors are closed, giving them fewer ways to escape outdoors. If you are seeing drain flies in your home, it is a good idea to learn how to get rid of sewer flies and take preventive steps before the problem gets worse.
