How to Kill Drain Flies Fast: Best Ways to Get Rid of Drain Flies for Good
If you’ve noticed tiny moth-like insects hovering around your sink or shower, you’re likely dealing with drain flies (also called fruit flies, sewer gnats or moth flies). While harmless, they breed in the organic sludge inside drains, multiply quickly, and can make your bathroom or kitchen feel unsanitary.
The good news? With the right methods, you can kill drain flies fast and prevent them from coming back. Here’s a step-by-step guide on the best ways to get rid of drain flies.
Step 1: Identify the Drain Fly Infestation
Before you can get rid of drain flies, you need to confirm where they’re breeding. Common sources include:
- Kitchen and bathroom sinks
- Shower and bathtub drains
- Basement floor drains
- Air conditioner condensate lines
Step 2: Flush Drains With Drain Fly Killer Powder
The simplest way to start killing drain flies is by applying Donaldson Farms Drain Fly Killer Powder. Simply add 1/4 cup of powder in any effected drain and immediately pouring 1-2 cups of very hot water down which activate the foaming action. This will slowly make its way down the drain eradicating the drain flies.
Step 3: Scrub Away Organic Buildup
Drain flies lay their eggs inside the slimy buildup along drain walls. To stop them from reproducing:
- Use a stiff drain brush to scrub the inside of the pipe.
- Remove and clean the drain stopper or strainer.
- Follow up with another application of Donaldson Farms Drain Fly Killer.
If the flies keep coming back, it may be because a high amount of gunk is in your pipes.
Step 4: Kill Adult Drain Flies Immediately
Even after cleaning, adult flies may remain for a few days. To eradicate them completely:
- Place sticky fly traps near sinks and drains.
- Vacuum them with a hose attachment.
Step 5: Prevent Future Drain Flies
Once the infestation is gone, prevention is the key to keeping your home pest-free:
- Run water weekly in rarely used drains.
- Clean sink strainers and stoppers regularly.
- Use a natural monthly drain treatment like Donaldson Farms Drain & Fruit Fly Killer to stop buildup before it starts.
