Green GobblerFruit Fly Killer+ - Kills Fruit Flies, Drain Flies & Sewer Flies, Gel Treatment for Use in Sinks & Pipes - Safe for Septic Systems, 32oz - Up to 8 USES (2 Pack)

Works fast. You have to treat the sinks/drains to get rid of the source. No more breeding, I just had to take care of strays flies. Good price. Doesn't smell bad. Easy to use (don't pour straight down). Works well with the stickers and the trap solution. Highly recommend.

Works great for sewer flies, fruit flies as well

Ease as usage dispense. Smells good, poured into drain and the drain gnats appeared less. This after an extermination which I had to follow up with my own finance to completely get rid of them, I live/rent in a NYC Borough.2 bottles is a value for their effectiveness. Pour and leave around the drain as instructed. No flies entered while product there and I believe it quickly went to area to cease nesting process. That application process worked immediately. Arrived quickly.

We live in an old apartment and ever spring and summer, we get drain flies. So this year my husband suggested we try Green Gobbler. We bought this liquid and some of the drain sticks. So far, the drain flies are gone!

This product did not lessen the number of fruit flies at all and it was more costly than powders I have tried in the past.

Works great, put it down the drain at night before you go to bed but put the drain plug in all your drains. Take care of any standing water.

Works ok but not as good as advertised

I had them NASTY flying things in my bathroom so irritating the effectiveness of how it works so fast in 2 days they were GONE it’s easy to use it’s safe an it’s definitely worth the money to purchase the value for the money as well used .. that’s Amazon an it came in one day
