Green Gobbler Fruit 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)

Worked well! I poured half the bottle in the tub drain and let it sit overnight. Then I filled half the bathtub with hot water and opened the drain to flush everything through with some force from the draining water. ALSO - if you have a faucet drip then you will need to fix that, or put a bowl or bucket in the tub to cover the drain and catch the drips. The drain needs to dry out between showers. The bugs thrive in the moisture.

This works like a charm and has a pleasant smell. I kept my sinks in all areas where i placed the product closed over night (and in some areas a little longer). I waited two days and then refreshed my drains again with the product. I no longer have any problems. Would HIGHLY recommend.

Works well

Product is only effective as long as you don’t need to use the sink. I have keep reapplying and it’s not very efficient. Seems effective otherwis, but will not purchase again.

Works great.. Will buy again

Normally, I love this brand but I'm really upset about this product that's supposed to take care of fruit flies and sewer flies. Instructions state that leaving it in the drain overnight is ideal so that's what I did. They also say that for best results, use it several times so I repeated the process the next night. Both times, I wiped away the excess with paper towel since rinsing them wasn't an option. So, not only has it eaten the finish off of my drain (or whatever the correct term is), this morning there were several sewer flies. I am not a happy girl. So, this is an update. I contacted the Green Gobbler customer service folks copying the review above and since they had no way for me to attach the pictures below, I described what had happened. I received back a boilerplate email describing that some drains are tougher to unclog than others. Really? I write about a product designed to rid your drains of fruit and sewer flies and they respond with info about unclogging my drains? I responded telling them that I was disappointed that they hadn't even taken the time to read my comment. Pretty poor and what's worse is that they did not respond to then at all to me. I'm just disgusted as I have used their drain cleaner several times and it's done a great job but this has soured me on the company.

It works! I thought I would not get rid of what I considered to be an infestation. Took a couple of days but then one day gnats ere at the bottom of the container. No bad smell, no process to it-just open up and they will come! LOL. Would definitely buy again.

I had five fruit flies in my bathroom sink in the morning. I used this Green Gobbler Fruit Fly Killer one time and the all the flies were gone, and have stayed gone....
