KINZUA ENVIRONMENTALFly-Zyme, Highly Concentrated Enzyme Drain Cleaner for Pipes, Drain Gel for Fruit Flies, Organic Waste Degrader & Odor Neutralizer, 1 Gallon

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!

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

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.

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.

I have ordered this product multiple times and used it for several weeks. The flies (which arrived in potting soil) have decreased but not disappeared. The most recent order arrived only partially full with significant leakage.

Added to drains the day it arrived. Working great so far.

After bleach and all the things, this product too care of the fly eggs in no time! Smells decent and took away all the larvae and gunk from the drain and cracks in the grout walls. No more fly worms in my bathroom!
