Eliminates Sewer Gnats
Works well to eliminate Sewer Gnats in drains! Easy to use. At night I pour a small amount down my drains, enough to cover the pea traps. Then let it sit overnight. You may have to repeat this for several nights to completely get rid of the Sewer Gnats but eventually they will be gone!

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.

Patience Required
I just got this and have only applied once. I will update my review after using it for a while. But I want to point out to those leaving negative reviews that the paper instructions point out that these infestations may take time to resolve. A week or more. It may require “multiple daily applications” and they recommend you leave the drain uncovered. I had not seen this last piece of advice before in other products that I have tried. Or with pest control companies who have treated my drains.. So people who have just used it once and seen no results need to keep applying it for a while before they give up. That would be my recommendation. I will update my review as I said, after, I’ve tried this for at least a month. I have had this infestation for more than a year and anticipate it will take a while to take care of.

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.

Getting the job done!
Tried this for a solid week in every drain & it did not work very well. I would not recommend this product so don't waste your money. I bought the Green Gobbler brand & it works much much better! I am retired & live off SS. I didn't work all those years to waste my money now!

BUY THIS ONLY
If there’s a review to read, please read this one!!I moved into a newly constructed apartment complex and was the first to move in. The new construction was built over what was previously farm land and has caused many insect issues. One of my biggest concerns were the fruit flies that multiplied pretty quickly. I had so many sticky traps, fruit fly concoctions, and zappers every where in my small 700 sq fr apartment. None of that worked. Don’t get me wrong, it was killing them, but not getting rid of the problem. I looked around Amazon and found this product and thought why not give it a try. At this point I had already killed over 1000 fruit flies in a week. It was seriously horrible at this point. They were getting in my drinks, food, literally flying into my nose and eyes. Absolutely disgusting. So I purchased this as well as some drain covers and within 3 days they all died. The combination of this and keeping them trapped in with drain covers is all it needed to take them out. WORTH every penny! My apartment complex is now buying this product for every apartment to help rid of the fruit flys for other tenants.

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!!!
