How to Get Rid of Drain Flies in Sinks, Showers & Floor Drains
Drain flies usually come from organic buildup inside drains — not from the room itself. The key is cleaning and maintaining the drain where they breed.

Why Drain Flies Keep Coming Back
Drain flies are commonly found around sinks, showers, floor drains, utility rooms, bathrooms, bars, restaurants, kitchens, and mop sinks. If they keep returning, the problem is often inside the drain.
Over time, drains can collect organic buildup, grease, soap residue, food particles, and other material. This buildup can create conditions where drain flies are attracted and may continue to appear.
Spraying the visible flies may reduce what you see temporarily, but it does not address the buildup inside the drain. A better approach is to treat the drain itself.
What Are Drain Flies?
Drain flies are small, moth-like flies often seen around drains, sinks, showers, basement floor drains, utility rooms, and commercial kitchens. They are usually a sign that moisture and organic residue are present somewhere nearby.
The Real Problem: Organic Drain Buildup
Drain flies are often associated with organic buildup inside drain lines. This buildup can cling to pipe walls and provide the kind of damp, dirty environment that attracts drain flies.
That is why Covington Drain Defense Gel is positioned as a drain and pipe treatment — not a harsh bug spray. The goal is to help clean and maintain the drain environment.
Organic Buildup
Food residue, grease, soap film, and sludge can collect inside drains.
Odors
Dirty drains can create unpleasant smells in kitchens, bathrooms, and utility areas.
Recurring Flies
If the source remains untreated, drain flies may continue to return.
How to Get Rid of Drain Flies
Step 1: Identify the Drain Source
Look near sinks, showers, floor drains, mop sinks, laundry drains, garbage disposals, and unused drains. The source is often the drain closest to where the flies are seen.
Step 2: Clean the Drain Opening
Remove visible debris, hair, soap scum, or buildup from the drain cover or opening.
Step 3: Treat the Drain
Apply a drain treatment designed to cling to the inside of the drain and help reduce organic buildup.
Step 4: Repeat as Needed
Heavy buildup may require repeated applications. Maintenance use can help keep drains cleaner over time.
