How to Get Rid of Drain Flies in My House 

Whether the drain flies are in your sump pump pit, ejector unit, or a standard drain, you can follow these steps to flush the area clean. 

1. Hot Water

The most effective way how to get rid of drain flies to expose them to hot, but not boiling water. You don’t want to cause the surface materials to crack! Pour an about one-half gallon of lukewarm fluid through the drain first. If it disappears quickly, you know that it is functioning correctly. Run the hot water through next because this action kills the larvae.

2. Industrial White Vinegar

After you douse the fly larvae in hot water, use industrial-strength white vinegar (sometimes called “cleaning vinegar”) to exterminate individual pests stuck inside the pipe. You’ll need 1-2 cups for this task.

Do not use bleach for this step. Although some professionals recommend it over vinegar, the caustic nature of the product could damage your pipes without removing the organic residues that initially brought the flies.

Please remember that mixing vinegar with bleach creates chlorine gas. Do not combine them at all.

3. Salt and Baking Soda

If you continue to see insects appearing around your home, a concoction of 1/2 cup baking soda and 1/2 cup salt with one cup of white vinegar can help to sanitize your drain. You may see a foaming action occur when you pour it – that is normal!

This liquid must stay in your drain overnight to ensure it kills the larvae in the pipe. You can also wait eight hours during the day to complete this step. Flushing the area with hot water will sanitize the surfaces, killing the flies, larvae, and eggs.

What Causes Drain Flies? 

Drain flies appear when there is stagnant water or organic material in your pipes. The smell that develops lets the insects know that there is a place to breed.

They’ll enter your home through whatever openings are available. Some even come through open windows or doors as you manage the interior environment. Once they get inside, they’ll fly toward the drains that contain the organic material.

That’s why one of the best preventative actions you can take to stop drain flies is to you each sink and floor drain regularly.

Drain flies become active in the evening. You’ll see them congregate around your sinks and floor. Some people mistake Phorid and Fruit flies for these pests, so it is essential to identify the infestation’s real source. Each treatment option is a little different.

Will Drano Kill Drain Flies?

Drano is a lye-based product that works to dissolve tough clogs in your pipes. It is such a powerful product that it can dissolve tissue with enough exposure to it. Pouring it down the drain will certainly kill drain flies, larvae, and eggs.

If you have a clog in your pipes with organic matter, this issue could be the attractant for the flies. Removing it with Drano could resolve your issue.

When water runs through the drain freely, the Drano will do the same. There wouldn’t be enough exposure to the lye to remove the infestation because the liquid would pass through the area too quickly.

Only the removal of the breeding grounds will stop this problem.

If you have tried Drano and other removal methods without success, it is time to contact a drain fly plumber or exterminator to correct the issue.

Do You Need Help with Your Drain Flies?

Drain flies are a nuisance pest. They don’t migrate to the other areas of your home. Still, these insects can make it uncomfortable to be around your kitchen and bathroom areas.

Since drain flies feed on the organic matter found in your pipes, they could be thought of as a beneficial pest.

Once you get rid of the infestation, it is crucial to remember that maintaining your drains’ cleanliness or sump pump pit must continue. Without a proactive approach, the flies are likely to return.
