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

This stuff really works! I had really disgusting roommates who would leave food and unwashed dishes in the sink which attracted a lot of drain flies. This stuff kills the eggs in the drain. Get a big catcher and your problem will go away!

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.

Smells good, kinda worked, easy enough to apply and use, but ultimately we still had to call the bug man, the stuff didn’t take out the drain flys…

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 did work after a few treatments. Didn't notice after first two treatments, but overall the 3rd and 4th did work on drain flies and odor in drain. Follow directions and it should work. Not as thick as in viscosity as I thought it would be. It helps to pour 7-8 cups boiling water first and then wait a few minutes to use product.

Killed the drain flies when the home remedies I tried did not.

Get this to prevent gnats. I dislike gnats a lot! I would recommend cleaning all sinks with banking soda and hot water then pore this after.

I purchased Fyy-Zyme hoping to eliminate the drain flys that developed after being away from home for the summer. Returning home from our summer vacation we noticed a lot of “fruit flies” in our home. There was no fruit or vegetables left to breed or attract flies. The flies seemed larger than fruit flies, and more pesty, flying right into our faces and eyes. After doing internet searches we decided they must be drain flies. They were predominately in our master bath, a few in the kitchen. Apple cider vinegar and Dawn dish soap caught a few, but not many. Internet searches presented a lot of products, I chose Fly-Zyme because we have a septic system for our home. The gallon arrived encased in a plastic bag, no leakage in the padded box. I cleaned our two bathroom traps, the shower trap was not serviceable, and the kitchen sink trap was not easily accessible. I then poured boiling water drown all traps. I poured 6 ounces of Fly-Zyme down each trap nightly, until the gallon was gone. Each sink received this treatment for five consecutive nights. It’s now been over a week since the last treatment and our fly issue shows little improvement. I guess an exterminator will be our next option.

“I was struggling with a persistent drain fly issue in my bathroom , but this drain fly remover was a game-changer! The application was super easy—just pour it down the drain, let it sit, and flush with water. Within a couple of days, the flies were completely gone, and they haven’t come back since. I love that it’s non-toxic and safe for my pipes. The fresh scent was a nice bonus, too! Highly recommend this product to anyone dealing with pesky drain flies—it works like a charm!”

Dictated.. So far so good. Still a few flies but doing as it says on the bottle.

I got to be honest I'm still using this product it works and does its job for temporary

We had an infestation and this did the trick straight away

I’m not sure how well it works the cold weather arrived!
