Works great for sewer flies, fruit flies as well

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.

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.

It’s gnat and fruit fly season and I am preparing ahead. We buy a lot of fruits and bananas are the worse thing for fruit flies, so I’m ready for them. I poured some in my kitchen sink and put the stopper over the drain and left it over night to get rid of the smell and gnats and eggs

Works ok but not as good as advertised

It works great

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.

This stuff is amazing! I poured it in my drain last night and I woke up to very few bugs flying around. My daughter told me about this stuff, she said she used it and the bugs were gone quickly. I can't believe how quick it worked. I will now keep this stuff on hand just in case I need it again.
