13 Secrets You Didn’t Know Could Get Rid of Drain Flies Instantly

If you’ve noticed small, moth-like insects hovering around your kitchen or bathroom drains, you might be dealing with a drain fly infestation. These tiny pests, also known as sewer gnats, breed in organic matter found in damp, neglected drains.

While they don’t bite, their presence can be incredibly frustrating, and trying to eliminate them can seem like a never-ending battle. Thankfully, numerous effective ways exist to get rid of drain flies quickly and easily.

In this article, we’ll explore 13 lesser-known methods that you can use to kick those pesky drain flies to the curb—without spending a fortune on professional extermination.

Whether you’re looking for a natural or store-bought remedy, there’s a solution here.

1. Boiling Water Magic

One of the quickest and simplest ways to get rid of drain flies is to pour boiling water down your drains. The hot water will kill any larvae, eggs, or adult flies that are residing in your pipes.

It also helps flush out any debris that could serve as breeding grounds. Boiling water is a non-toxic, chemical-free solution that works wonders, especially when you’re dealing with a small infestation.

To use boiling water, simply bring a kettle of water to a rolling boil. Then, carefully pour the water down the affected drain.

It’s best to repeat this process two or three times to ensure that the larvae and eggs are completely eliminated.

Make sure your pipes can handle the heat—boiling water may damage older or fragile ones.

2. Baking Soda and Vinegar Power Combo

Baking soda and vinegar aren’t just a great cleaning duo—they can also be your secret weapons in the battle against drain flies.

This powerful combination works by disrupting the breeding cycle of the flies and breaking down the organic matter where they lay their eggs. The fizzing action also helps dislodge any debris in your drains.

To use this method, pour ½ cup of baking soda down the affected drain, followed by ½ cup of vinegar. The two ingredients will react, producing a fizzing sound.

Let this mixture sit for at least 30 minutes (or overnight, if possible) before flushing the drain with hot water. This solution eliminates drain flies and helps clean your pipes and remove unpleasant odors.

3. Hydrogen Peroxide: A Hidden Gem

Hydrogen peroxide is another highly effective solution for killing drain flies, especially when combined with baking soda’s cleaning power. It’s a mild antiseptic that can kill bacteria and fungi in your drain, eliminating the ideal environment for drain flies to breed.

To use hydrogen peroxide, pour 1 cup of it down the affected drain, followed by 1 cup of water. Allow it to sit for at least 30 minutes before flushing the drain with hot water.

The peroxide kills the larvae, eggs, and any other organic material that could attract flies. It’s a fast, affordable solution that works well on small and moderate infestations.

4. Salt and Hot Water for Immediate Action

Salt is a simple but powerful tool for dealing with drain flies. When combined with hot water, it acts as a desiccant, dehydrating the larvae and eggs that may be lingering in your drains. The salt also helps prevent the buildup of organic matter that drain flies thrive on.

To use salt, pour about ½ cup of regular table salt down the drain and follow it with a gallon of hot water. Let it sit for a few hours (or overnight) before flushing with additional water.

This method is especially helpful for clearing out any stubborn organic material that may be contributing to the infestation.

5. Commercial Drain Fly Sprays

If DIY solutions aren’t working, you may want to consider a commercial drain fly spray. These sprays are specifically designed to target drain flies and other common pests.

Many of these products contain ingredients that kill the larvae, eggs, and adults on contact, providing instant relief.

When choosing a drain fly spray, look for one that is safe for use in drains and pipes. Most sprays can be sprayed directly into the drain or on the surrounding surface.

Follow the manufacturer’s instructions for the best results. While these sprays are generally effective, they should be used in conjunction with other cleaning methods, like boiling water or vinegar, to prevent further infestations.

6. Fly Traps That Really Work

Fly traps are a great way to catch and eliminate adult drain flies. These traps use attractants, such as vinegar or sugary liquids, to lure the flies in, where they get stuck and eventually die. You can make your own simple fly trap using household items like a jar and plastic wrap.

To create a trap, fill a jar with a small amount of apple cider vinegar (which attracts drain flies) and cover the top with plastic wrap. Poke a few small holes in the wrap so the flies can enter.

Leave the trap near the affected drain overnight. In the morning, you’ll likely find a few dead flies inside. Repeat this process for several days to catch any remaining adults.

7. Using Essential Oils to Repel Drain Flies

Essential oils aren’t just great for creating a relaxing atmosphere—they can also be used to repel drain flies.

Certain oils, such as eucalyptus, peppermint, and citronella, have strong scents that drain flies find unpleasant. By creating a natural repellent, you can keep these pests at bay.

Mix 10 to 20 drops of essential oil with 1 cup of water in a spray bottle to make your own essential oil spray. Shake well and spray the solution around the affected drain and any other places where flies are present.

The scent will deter the flies from returning. You can add a few drops of essential oils directly to your drains for an added repelling effect.

8. Apple Cider Vinegar for Drain Fly Traps

Apple cider vinegar is not only effective at attracting drain flies for trapping, but it also works as a mild cleaner. You can catch and kill adult drain flies by setting up a simple trap with apple cider vinegar.

Pour about ½ inch of apple cider vinegar into a small bowl or jar to create a trap. Cover it with plastic wrap and poke small holes in the top.

The flies will be drawn to the vinegar’s scent and enter through the holes, but they won’t be able to escape. This method is a simple yet effective way to reduce the fly population in your home.

9. Citric Acid to Eliminate Fly Breeding Grounds

Citric acid is an excellent way to clean drains and kill drain fly larvae. It works by breaking down the organic matter that the flies feed on, and the acidic nature of citric acid helps create an inhospitable environment for them.

To use citric acid, dissolve about 2 tablespoons in 1 cup of water and pour it down the drain. Let it sit for 30 minutes to an hour before flushing with hot water. This method eliminates drain flies and helps keep your pipes clean and clogged-free.

10. Regularly Clean Your Drains with a Drain Snake

Regular maintenance is key to preventing drain fly infestations. A drain snake is one of the most effective tools for this job, as it can help break up clogs and remove debris from your pipes. Keeping your drains clear will make them less likely to attract flies and other pests.

Use a drain snake once a month or whenever you notice a gunk buildup in your drains. Removing these blockages reduces the chances of drain flies finding a place to breed.

11. Preventative Measures: Keep Flies from Returning

After you’ve eliminated your drain fly problem, it’s important to take steps to prevent them from coming back.

Clean your drains regularly, remove any standing water around the drain area, and keep your kitchen or bathroom dry. Sealing any cracks or crevices around your pipes will also help keep flies from entering.

Regular maintenance, such as flushing your drains with boiling water once a week, can help ensure that flies don’t find a new breeding ground in your pipes.

12. Professional Help: When It’s Time to Call an Exterminator

If your drain fly infestation is severe or persists despite your best efforts, it may be time to call in a professional.

An exterminator can identify the source of the problem and offer targeted solutions that go beyond simple DIY methods. They can also advise on long-term prevention strategies to keep your home fly-free.

While professional services may cost more, they are often the best option when all else fails. A pest control expert can ensure your home is fully treated and the problem doesn’t return.
