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

I had phorid flies in my studio apartment. Not many, but in a small apartment they were very noticeable and I swear they were taking up 99% of my mental capacity. I would go to sleep thinking about the flies and wake up still thinking about the flies. This worked very quickly. BUT YOU HAVE TO PUT OTHER TRAPS OUT TO CATCH THE ADULTS. I used Zevo light traps which were the best, and put out little tubs of apple cider vinegar with dish soap. This also helped me monitor the number of flies daily. I used the flyzyme twice a day in all of my drains, essentially any time I was able to let it sit for a few hours. I also used it for 10 days straight. By the end I had no more flies.

I have purchased this product 9 times since 2021. It did a great job of keeping my drain gnats away.I recently bought a new bottle and found that THEY CHANGED THE PRODUCT. The bottle was not full - and not because it leaked during shipment. The new bottle was tightly wrapped in cellophane and there were no signs of leakage. Additionally, the product itself has clearly been watered down. It used to be a very thick gel that would cling to the drain. Now it is a watery syrup. Clearly, the company is cutting corners, yet charging the same price. I doubt that the watery syrup will work as well as the thick gel.Update: Customer Service reached out to me immediately after my initial review. THEY REFUNDED MY ENTIRE PAYMENT, apologizing for my experience. They asked that I keep the product and assured me they have not changed the formula nor did they water down the product. I changed my rating to 5 stars for their outstanding customer service. I have always loved this gel. I’ve tried everything and this is the only thing that keeps my gnats under control. It also has a very pleasant smell. They won me over with the best customer service I have ever experienced on Amazon.

So far after using everyday I still have drain flies. Update! We had a bad leak! They were coming from there. Leak fixed and this problem is finally going away

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.

It seems to be working, I’m very pleased

Just tried so unsure if works, however the drain did smell fresher (no I didnt notice an order before because I don't stick my nose in the sink).

I followed the instructions and this product did not solve the problem. Still had drain flies.

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.
