Rockwell Invade Bio Drain Gel Gallon

This stuff is great! I went from gnats waking me out of my sleep to them being nonexistent in my house. They were everywhere. After one use of this in all of my drains, I didn't see a gnat for weeks and when I did see one it was minimal. My infestation is gone! I'll be ordering more of this and recommending to friends!

Most of the reviews for this product were favorable and it was a natural product so I decided to give it a go. I followed the directions exactly as they were provided and put in all of my drains at bed time every other day. During the daytime, I also dumped boiling water down the drains. The combination of these two things has rid my home of the drain flies. I had been finding 4 or 5 on my master bathroom wall every time I entered. They aren't harmful but are quite pesky and a nuisance. I wanted them gone. The orange smell is pleasant - no harmful chemicals and the problem is now resolved. I will continue to do maintenance care as suggested to keep the drains clean from build-up and prevent a further drain fly problem.

I don't know the difference between fruit or drain flies. I always figured I had fruit flies every summer because we always have lots of fresh fruit in the house. Problem was the dang fruit flies drove me crazy. I tried the traps at the store and made my own solutions. Both caught lots of flies, only they kept coming in waves. I tried this bio gel 3 years ago and for the first two years it worked great. I just poured a little in each drain in the house every night. Took care of the problem in a matter of a week. This past year, it did not work as well but still better than if not using the product. If your out of options, give this a try. I believe it's non-toxic, which is a bonus if you have kids or pets. I will continue to buy.

The product served it's purpose by killing the drain flies. It's fast working and not messy. Smelled like orange Gatorade.

I have been using this product since March in four drains in my bathroom. I followed the directions on the bottle. I initially only would see maybe one drain fly a week in my bathroom before using this product. After the first few days of using BioDrain, it must have disturbed the nest b/c I was seeing a few every day in the first two weeks. I kept using this every other day, I would let BioDrain sit in drains over night, then in week three I decided the next morning maybe I should pour boiling water down the drain. After a month of using Biodrain, I eventually didn’t see the pesky gremlins for two weeks straight. But it was short lived that BioDrain would let me extend longer than two weeks without having to start the process all over again. It’s like BioDrain treats the symptom, but doesn’t kill the colony.
