ACV for Gnats & Drain Flies: Why It Works (And What Works Better)
Share
If you’ve ever dealt with gnats or drain flies swarming your kitchen, you know how annoying they are — and how hard they are to fully eliminate.
Apple cider vinegar (ACV) is a proven natural remedy for attracting and trapping these pests… but how well does it really work? And are there more effective solutions?
Let’s break it down.
⸻
🪰 What Are Gnats & Drain Flies?
Gnats are tiny flying insects attracted to fruit, moisture, and organic decay.
Drain flies (also known as moth flies) breed in slimy residue found in drains, pipes, and garbage disposals.
Both are annoying. Both multiply fast. And both are drawn to fermented, sugary smells — which makes ACV a powerful trap base.

🍎 Why Apple Cider Vinegar Works
ACV gives off a strong fermented apple smell that mimics overripe fruit — a magnet for flying pests.
It’s especially effective when combined with dish soap, which breaks the surface tension of the liquid and causes the insects to sink and drown.

🏆 Best Types of ACV for Gnat Traps
Not all vinegar is created equal. For gnat traps, you want strong-smelling, raw, unfiltered ACV — the kind that smells like it’s alive (because it is).

🚿 Drain Flies Need a Deeper Fix
ACV traps work great for catching drain flies — but to stop the breeding, you need to kill the source inside your pipes.
Try this 3-step method:
1. Boiling water + baking soda down the drain
2. Follow with white vinegar — let it foam
3. Rinse 10 minutes later with more hot water
Repeat for 3–5 days.
