This stuff is amazing after the first application the drain fly was down by 60% after the second application I only had a few now they are gone completely. To stop them returning I give the drain a small amount to stay on top of the situation.

Worked great to eliminate drain flies. Easy squeeze bottle with a gel liquid. Needed two applications, but then no more flies.

Buy a couple bottles for initial treatment and maintenance. A Zevo blue light next to sinks as well. Works well. Smells fresh. I moved into a new place and a soon as I started running the water, drain gnats appeared. I did all the things Google told me to do. Nothing worked. Apple Cider traps only brought more out. Bleach, peppermint, and boiling water did nothing. Bought this, a long skinny scrub brush, and Zevo lights. Has been a success!

I used this product six months ago to eliminate a drain fly problem in my kitchen. It worked. But they're back again (not in as great numbers though). So buying again and already seems to be doing the trick again after three nights of treatment.

If you have any questions if this works, I’m gonna let you know right now it does. First off they have great customer service. I wasn’t sure about the instructions but when I called the gentleman was patient explained everything. Next, I had drain bugs By the time I figured out what those little flying things were, I had an infestation. I live in a studio apartment, so my Kitchen is my Bedroom. I use this for two days. The first day I poured it down the drains going around the edges, so it covered the whole pipe all around going down. I did the 6 ounces they suggest At around 2 PM then added some before I went to bed I did not use my sink at all. I tried to wait as long as possible, the next day So when I woke up There wasn’t that many! Then I did it again yesterday so that’s the second day I woke up this morning not one bug a lot of dead ones But none anywhere to be seen. This product works. It’s definitely worth every penny I first tried those home hacks don’t waste your money on that. Overall, great product!! I will definitely be buying to maintain my pipes.

So I was a little nervous about how the house would smell but I was willing to forgo any unwanted smells if it got rid of the unwanted pest that had been invading my home. So the 1st day as expected they were angry and came out of their layer after I had used the product on all the problem drains in my home. I had my handy bug zapper right there with its calming blue light to accommodate them and send them into oblivion humanely. So 2nd night after application #2 wasn’t as many pest so great. Night #3 maybe one or 2 pest but other than that I think it’s taken care of the issue and I still have plenty left in case of any other future issues. Also it seems to have made the drains work a little bit better so I would say that it does work to clean out grease and clogs as it said.

I have two sink drains that had think in them and smelled from time to time. I had tried boiling water, toilet bowl cleaner, chlorinated cleaners, vinegar with no success. I researched and bought this. I read the directions and it said 6 oz for 5 days in each drain and didn’t the math so I would run out prior to the treatment. So I did about 2 oz down each drain and one drain was clean and clear after two uses but the other wasn’t. I took a kettle of boiling water and it cleared the drain instantly with the use of this product when boiling water hadn’t worked previously. I will keep treating the drains for a few more days to be sure and follow up at the end with a lot of boiling water but this worked way better than expected. I didn’t think it would clear the gunk because my one drain was pretty gummed up. Will use again for sure.

Put down drain before bed. I used it during the day as well since no one was home, did it for about three days so far, no flies.

I used for multiple days to no avail. I could tell life cycle by size, but not stop. Customer service is great.

I travel a lot, so I am away from home often. I developed a nasty case of drain flies for months. Nothing I did worked - bleach, vinegar, covering drains. I finally caved and bought this begrudgingly due to the price. But oh my gosh - it worked after one application! I pour a glug down each drain (so easy to use and no overly strong smell), left for a week and those peasky flies were 100% gone. I still have half the jug left in case it happens again, but it's been weeks and I'm still fly free. Now that I know it was a one time purchase, and not getting stuck in a loop of having to repurchase, I would buy again - great value!

I ordered this product for drain gnats. We had them years ago and an exterminator sold us a similar product and u it it in your drains every night close them all for 5-7 nights and it’s supposed to kill any reproduction. They feed off any hair or grime or anything trapped down in your drains. This stuff defiantly does not seem powerful enough to kill the fys or their larva and I would not recommend. The stuff i wanted they won’t sell in California.
