Are you noticing tiny flies buzzing around your kitchen sink and suspecting they might be fruit flies in your drain? It’s a common household nuisance, and while you might be dealing with fruit flies, it’s also possible you’re encountering drain flies or even fungus gnats. Identifying the culprit is the first step to effectively getting rid of them.
Are They Really Fruit Flies in Your Drain? Understanding the Pesky Culprits
While often called fruit flies in the drain, these tiny insects thriving in your sink are more likely drain flies (also known as moth flies or sink flies). Fruit flies are indeed attracted to drains, but they primarily breed on fermenting fruits and vegetables. Drain flies, on the other hand, specifically breed in the stagnant, organic matter that accumulates inside drains.
To accurately identify your tiny tenants, here’s a quick comparison:
-
Fruit Flies: These are typically brown or tan with red eyes, about 1/8-inch long, and have a body shape similar to house flies. You’ll usually find them swarming around overripe fruit, open trash cans, and garbage disposals. While they might be seen near drains seeking moisture or food particles, drains aren’t their primary breeding ground.
-
Drain Flies: Smaller than fruit flies, drain flies have a distinct moth-like appearance with fuzzy bodies and wings, often described as dark, fluffy dots. They are weak fliers, often seen resting on walls and surfaces near drains. Their larvae thrive in the slimy buildup within drains, making drains their ideal breeding location.
-
Fungus Gnats: About the same size as fruit flies, fungus gnats have a mosquito-like body shape, are dark brown or black, and are commonly found around houseplants or moist soil. They are less likely to be directly related to drains but can be mistaken for fruit or drain flies.

Why Are Flies Attracted to Your Drain?
Regardless of whether they are fruit flies or drain flies, the attraction to your drain stems from the same basic needs: food and breeding grounds. Drains, especially kitchen drains, accumulate organic matter like food scraps, grease, and hair. This creates a moist, nutrient-rich environment where fly larvae can feed and develop. For drain flies, it’s their primary breeding site. Fruit flies might be drawn to the drain for the readily available food source and moisture, especially if the drain isn’t cleaned regularly.
How to Get Rid of Fruit Flies (and Drain Flies) in Drains: DIY Methods
Eliminating these drain-loving pests requires targeting both the adult flies and their breeding grounds. Here are effective DIY methods to get rid of fruit flies and drain flies in your drain:
-
Boiling Water: A simple and immediate solution is to pour boiling water down the drain. This can kill fly larvae and eggs, as well as dislodge some of the organic buildup. Repeat this several times a day for a few days.
-
Baking Soda, Vinegar, and Salt: This classic DIY drain cleaner is effective against drain flies and fruit flies breeding in drains.
- Pour 1/2 cup of baking soda down the drain.
- Follow with 1/2 cup of salt.
- Then, pour 1 cup of white vinegar down the drain.
- Let the mixture fizz and sit overnight.
- Flush with boiling water in the morning.
Repeat this process 2-3 times a week.
-
Commercial Drain Cleaners (Enzyme-Based): Chemical drain cleaners can be harsh and potentially damaging to pipes. Opt for enzyme-based drain cleaners specifically designed to break down organic matter. These are a more environmentally friendly and pipe-safe option to eliminate the flies’ food source. Follow the product instructions carefully.
-
Clean the P-trap: The P-trap is the curved section of pipe under your sink. It’s designed to trap water and prevent sewer gases from entering your home, but it can also trap organic matter that attracts flies.
- Place a bucket under the P-trap.
- Using pliers, loosen the slip nuts at both ends of the P-trap.
- Carefully remove the P-trap and empty its contents into the bucket.
- Clean the P-trap thoroughly with a brush and soapy water.
- Reassemble the P-trap, ensuring the slip nuts are tightened securely.

- Apple Cider Vinegar Trap (for Adult Fruit Flies): If you are dealing with adult fruit flies drawn to the drain area, an apple cider vinegar trap can be effective.
- Pour apple cider vinegar into a jar or glass.
- Add a drop of dish soap (this breaks the surface tension).
- Cover the top with plastic wrap and poke small holes in it.
- Fruit flies are attracted to the vinegar, will enter the trap, and get stuck.
Prevention Tips to Keep Flies Away from Drains
Prevention is key to long-term fly control. Here’s how to prevent fruit flies and drain flies from infesting your drains:
- Regular Drain Cleaning: Clean your drains at least once a week using boiling water or the baking soda and vinegar method to prevent organic matter buildup.
- Avoid Food Down the Drain: Be mindful of what goes down your drain. Dispose of food scraps in the trash or compost instead of rinsing them down the sink.
- Use Drain Covers: Use drain covers or screens to catch hair and larger debris, reducing buildup in the drain.
- Keep Sink Area Dry: Wipe up spills and keep the sink area dry to minimize moisture that attracts flies.
When to Call a Professional
If DIY methods fail to eliminate the fly problem, or if you suspect a larger infestation, it’s best to consult a professional pest control service. They can accurately identify the type of fly and implement more targeted and effective treatments.
By understanding the difference between fruit flies, drain flies, and fungus gnats and implementing these preventative and removal methods, you can effectively get rid of flies in your drain and maintain a pest-free kitchen.
