Rockwell Labes -InVade Bio Drain Quart (32oz) ~ Restaurant Drain Gel Organic Treatment ~ Eliminates Odors, Fruit, Phorid, and Drain Flies

This product really works! I recommend placing it in the drains overnight to ensure no water is running, giving it a chance to take effect. I noticed a significant reduction in fruit flies within just 24 hours of use. It doesn’t require much effort, making it a simple and effective solution. Highly recommended!

with the “volcano”: 1/2 c. baking soda down the drain, followed by 1c. vinegar, followed by as much boiling water as you can easily produce. Do this twice, 2 days apart. Then you can use this product every 3-4 days to control the gunk inside the drain, in which they live. The manufacturer implies that this product alone will kill the flies, but that’s not been my experience. It’s a control, and it work well as one.

I liked the product but didnot totally eliminate sewer flies.

When applied as recommended, say goodbye to drain-flies! We love this stuff.

The spout allows you to squeeze the liquid and completely cover the inside of the drain and it definitely reduced the amount of drain flies that I was having problems with.

Ain’t it does work

This is a yearly staple for us down here in Florida. As soon as it gets hot and they bugs start flying we apply this to all the drains and within a day the bugs are gone. Is a must have if you love in a hot climate

When I originally purchased this 3 years ago, it came, it worked and the formula was orange and thick. The last two times I purchased this size bottle, it came, it doe nothing and it is light yellow so a different formula. Not a good upgrade but won't buy this again at all.
