VERY EFFECTIVE!!!!
GREAT PRODUCT!!!!! Only product I will use because it works!! We see a difference with the FIRST application. I simply used a clear cup, measured & marked 8 ozs and went to work at night after all were sleep!!! Gotta pour boiling water first thing in the morning to rinse each drain but I did 3-5 treatments to rid the drain flies and gnats. YOU WILL SEE A BIG DIFFERENCE and customer service is GREAT! Scent is not bad at all. This is my go to product whenever the need arises!!!

Worked Fast & Solved My Fruit Fly Problem
I bought this because my main bathroom had a full-on fruit fly problem, and it was honestly overwhelming especially when having visitors over. It was embarrassing and just gross. After using this drain gel a couple of times, I noticed a huge difference. Within a short time, the flies were completely gone. It was easy to use, and I like that it targets the source in the drain instead of just killing the flies you see flying around. It definitely did the job, and I’m so relieved I found something that actually works. Highly recommend if you’re dealing with the same issue.

Works
Worked! No funky smell & the irritating little monsters were gone within days. I had previously tried traps, blocking the drains & using baking soda & vinegar cleanses to no avail. I think this stuff is ridiculously expensive, but as a last resort I can say it works.

Most Disappointing
I am so disappointed in the effectiveness of this product. I have this persistent and annoying problem of drain flies, you know those little turds that seem to be hanging around your kitchen sink, smoking and drinking whatever intoxicating drinks they find in your sink's drain, then annoyingly buzzing around you, your house, and wherever it is you're trying to eat. In my desperation to get rid of these annoying flies, I purchased the "Fruit Fly & Drain Fly Killer - Simple Commercial Drain Gel Treatment – Eliminates Gross Fruit/Sewer Flies & Gnat Infestations from Any Drain. Fast & Easy - 1 Gallon (128 Ounces)" for $33.09. Based on the product's details and potential effectiveness, I expected to use only eight ounces per drain and have plenty leftover for any future occurrences. WELL, in three days I've managed to use about half of the jug's content, applying the gel as directed, and these flushing flies still seem to be kickin' it around the drain. I wish Amazon would critique a more effective five-star product.

Miracle product!!!
So pleased with my purchase. I have been fighting drain flys for over a year. A little infestation, became huge. I used several products along the way, and absolutely none compared to the results I had using this product. My infestation was mainly in the pipes of my washer. My bug zapper was killing almost 100 a day, while others drain flies would just find a spot on the wall near by. A few other products helped, but not like this product. After using as directed for the first time in over a year, I had no activity for almost a week. So treated the pipe a second time and it’s been 3 weeks with no activity. I plan on using the rest of the gallon on a monthly basis just to continue to kill any new growth that may occur. I can’t not tell you how impressed I am with this product considering how many things we have tried.

Waste of money, unresponsive seller, the only thing it "eliminates" is money in your wallet
I purchased this full gallon of Fruit Fly & Drain Fly Killer hoping to finally solve a persistent drain fly issue. I applied the entire gallon directly to the affected drain as directed, but it had zero effect. The flies were not reduced at all, in fact, they noticeably increased in the following days. I reached out to the seller and never received any response. Extremely disappointed with both the product performance and the lack of customer support. Save your money and look for something that actually works.

Great product!
It works with several applications. Flies started coming up from a seldom used bathtub drain. I tried DIY treatments with poor results. This stuff really works!
