## Description

desertcart.com: Fruit Fly Drain Treatment | Drain Fly Eliminator | Eliminates Gnats, Sewer Flies and More - Works in All Drains - 32 Fl Oz : Health & Household

Review: It works. But here are better ways. - Pros: 1. It fully coats the vertical drain surface very well. I could see that happening with a flashlight. 2. It does work. Slowly over 5 or more days, as the instructions say. With a flashlight you can see the scum reducing slowly day by day. We also used a shop vac to catch adult flies whenever we saw them; that works. However, now I know more, I ended up dismantling the under sink pipes and cleaning them. That's the fastest and simplest way. To keep the biofilm coming back in future I'm going to use Bio-Clean powder regularly which seems more cost effective. I also redesigned the twin sink drain to avoid horizontal pieces (even short ones) by changing to two p-traps in parallel. It is done in a code compliant way: no risk of siphon. Now with a p-trap directly under each sink strainer, there are no ceilings of pipe before the p-trap for flies to lay eggs. The dishwasher hose now dumps directly above a p-trap rather than travelling a horizontal section first. It's noisier now with the water on water impact when the dishwasher drains, but I prefer the thought of dishwasher debris now being vigorously flushed though the p-trap. Cons: 1. Instructions state "shake vigorously before every use". As the bottle gets emptier this results in froth. So much froth that it's hard to see where the liquid level actually is in your measuring cup. 2. It arrives with a low quality foil cover glued on to the opening under the cap. "Keep upright" writing on box is too small and probably often missed in transit, resulting in leaks, as happened to me. They could heat press the plastic opening instead and then we could cut it off with a knife to open. I have also bought some "needle nozzles" for a low-pressure (300psi) battery pressure washer which takes water from a bucket. These needle nozzles should allow light pressure washing inside drains (and washing machine) without dismantling. The dislodged material then falls down further into your drain system and creates new clogs in the short term, but once you get past that (with pure lye) and back to a clean system, keeping it clean from then on with Bio-Clean it what I'll try next.
Review: Great smell, clean drains, no flies! - Fantastic product! Cleaned what I could see in the drain better than the baking soda/vinegar mixture I made. I was able to eliminate the flies in one treatment! I would buy this as a drain freshener alone. The herbal scent had our bathroom smelling very clean.

## Features

- A Natural Fruit Fly Solution: Our non-toxic gel formula is safe for use around food and anywhere in the home, kitchen, bar, or restaurant.
- Drain Flies, Sewer Flies, Gnats, or Fruit Flies, any flies like to be in drain scum found in drains, pipes, or garbage disposals. This natural formula cleans out the scum from the drains, and it is safe for your plumbing.
- Home & commercial use: Our natural gel contains additional scum-busting properties, making this the most effective solution. Pour into a drain; this fast-acting treatment breaks up and digests drain scum.
- Occasional use of this gel treatment will keep your drains odor and scum free. By preventing the buildup of organic scum, you remove the risk of another problem.
- What to Expect: Some users commented that after the first treatment, they saw more flies. This is to be expected and means the product is working. By removing the drain scum, the flies leave. Please don't give up. Continue to treat as directed. You will see a decrease over the next few days or so.

### ⭐⭐⭐⭐ Worked pretty well for the drain flies in my kitchen
*by D***N on July 27, 2026*

We had a stubborn little colony of drain flies coming out of the kitchen sink every evening. Tried the usual boiling water and vinegar tricks with zero lasting results. This stuff cleared them up after about 3–4 days of nightly use. I just poured it down the drain before bed and left it. The flies mostly stopped showing up, which was a huge relief. It’s not instant magic, and I still get the occasional straggler, so I’m docking one star for that. But overall it did the job better than anything else I tried. Easy to use and doesn’t smell crazy strong. Worth trying if you’re dealing with the same problem.
