Nothing ruins a clean kitchen faster than a swarm of tiny flies buzzing around your sink. These pesky fruit flies seem to appear out of nowhere, hovering around your drains and multiplying by the dozens. If you’re dealing with a fruit fly problem that centers around your kitchen sink or bathroom drains, you’re not alone—and more importantly, you can fix it.
Fruit flies are attracted to moist, organic matter where they can lay eggs and reproduce rapidly. Your drains provide the perfect breeding ground with food particles, grease buildup, and standing water. The good news? Getting rid of fruit flies in your drain doesn’t require expensive pest control services or harsh chemicals. With a few simple household items and some persistence, we will tell you how to get rid of fruit flies in drain areas so you can eliminate these flying insects and prevent them from returning.

Understanding Your Fruit Fly Problem
Before diving into solutions, it’s important to identify exactly what you’re dealing with. Fruit flies are small insects, about the same size as a pinhead, with red eyes and tan bodies. They’re often confused with drain flies (also called fungus gnats), which are slightly larger and darker.
Both types of flies are attracted to similar environments, but their breeding habits differ slightly. Fruit flies typically lay eggs in rotting fruit, garbage disposals, and organic matter stuck in drain pipes. Adult flies can live for several weeks, during which time a single female can lay up to 500 eggs.
The key to eliminating any fruit fly infestation is targeting both the adult flies you can see and the eggs they’ve laid in your drains. This two-pronged approach ensures you break the reproduction cycle completely.
Method 1: Boiling Water Flush
The simplest method to kill fruit flies and their larvae is pouring boiling water down your drain. This technique works by washing away organic buildup and killing eggs on contact.
Heat a large pot of water to a rolling boil. Carefully pour the hot water down the affected drain in a slow, steady stream. The boiling water will clear away food particles and kill any larvae living in the drain pipe. Repeat this process twice daily for three days to ensure you’ve eliminated all stages of the fruit fly life cycle.
For best results, follow up with cold water to help flush away any remaining debris. This method works particularly well for minor infestations and serves as an excellent preventive measure.
Method 2: Baking Soda and Vinegar Treatment
This classic cleaning combination creates a powerful drain cleaner that eliminates fruit flies while deodorizing your pipes. The chemical reaction between baking soda and vinegar helps break down organic matter where flies breed.
Start by pouring half a cup of baking soda down your drain. Follow immediately with one cup of white vinegar. You’ll hear fizzing as the ingredients react. Cover the drain with a stopper or plastic wrap to contain the reaction for 15 minutes.
After waiting, flush the drain with hot water to wash away loosened debris and dead larvae. The bubbling action helps scrub the sides of your drain pipe, removing the film where fruit flies lay eggs. Repeat this treatment daily until the flies disappear.
Method 3: Apple Cider Vinegar Trap
While treating your drain, you’ll also need to catch the adult flies buzzing around your kitchen. Apple cider vinegar creates an irresistible trap that attracts fruit flies to their demise.
Fill a mason jar or small bowl with apple cider vinegar, leaving about an inch of space at the top. Add a few drops of dish soap, which breaks the surface tension and prevents flies from escaping. Cover the container with plastic wrap and poke tiny holes in the surface using a toothpick.
Place this trap near your kitchen sink or wherever you’ve noticed the most fruit fly activity. The vinegar smell attracts fruit flies, who enter through the small holes but cannot escape. Empty and refresh the trap every few days until the infestation ends.
Method 4: Commercial Drain Cleaner
For severe infestations, a commercial drain cleaner specifically designed for organic buildup can provide more aggressive treatment. Products like Green Gobbler target the root cause by dissolving organic matter in your drain pipes.
Follow the manufacturer’s instructions carefully, as these products contain stronger chemicals than household remedies. Typically, you’ll pour the specified amount down your drain, wait the recommended time, then flush with hot water.
Always ensure proper ventilation when using commercial drain cleaners, and never mix different products. This method works best for persistent fruit fly problems that haven’t responded to gentler treatments.
Method 5: Manual Cleaning with a Pipe Brush
Sometimes the most effective approach is the most direct one. A metal pipe brush can physically remove the organic buildup where fruit flies breed, especially in garbage disposals and the first few inches of your drain pipe.
Remove any visible debris from your drain opening. Insert the pipe brush and scrub the walls of your drain pipe, working the brush up and down to dislodge stuck food particles and grease. This physical cleaning removes the exact spots where flies lay eggs.
After brushing, flush the drain with hot water to wash away loosened material. Follow up with one of the chemical treatments mentioned above for maximum effectiveness.
Method 6: Beer and Dish Soap Trap
Similar to the apple cider vinegar method, beer creates an effective fruit fly trap using ingredients you likely have on hand. The fermented smell attracts flies, while dish soap ensures they can’t escape.
Pour beer into a shallow dish until it’s about half full. Add several drops of dish soap and stir gently. Place the dish near your kitchen sink or other areas where you’ve noticed fruit fly activity.
The flies will be drawn to the beer’s scent and become trapped in the soapy solution. Replace the beer every few days until you stop catching flies. This method works particularly well when combined with drain treatments.
Method 7: Salt and Baking Soda Scrub
For a more abrasive cleaning approach, combine salt with baking soda to create a scrub that removes stubborn organic buildup in your drains.
Mix equal parts salt and baking soda in a bowl. Pour this mixture down your drain, followed by boiling water. The salt acts as an abrasive agent, helping to scrub away film and debris where fruit flies breed. The baking soda helps neutralize odors and break down organic matter.
Let the mixture sit for several hours or overnight before flushing with more hot water. This method works especially well for drains that haven’t been cleaned in a while.

Preventing Future Fruit Fly Infestations
Once you’ve eliminated your current fruit fly problem, preventing future infestations requires ongoing maintenance and a few simple habits.
Keep your kitchen clean by wiping down counters daily and immediately cleaning up spills. Don’t leave dirty dishes in the sink overnight, as food particles attract fruit flies. Empty trash cans regularly and ensure they have tight-fitting lids.
Clean your drains regularly by pouring hot water down them daily and using the baking soda and vinegar treatment weekly. This prevents organic buildup that serves as breeding grounds for flies.
Store fruit in the refrigerator rather than leaving it on your kitchen counter, especially overripe fruit that attracts flies. If you do keep fruit bowls on your counter, check them daily and remove any fruit that’s starting to rot.
Pay attention to other potential breeding grounds like your garbage disposal, which should be cleaned weekly with ice cubes and citrus peels. Floor drains in basements or utility rooms can also harbor fruit flies if they contain stagnant water.
Keep your sink drains covered when not in use, especially overnight. A simple drain cover prevents flies from entering and laying eggs in your pipes.
