IBDC032 Invade Bio Drain Gel-1 Qt

It works!!I had sink gnats that were starting to get out of control. I ordered this stuff and followed the directions. It took a couple of weeks but I began to see the light at the end of the tunnel. Less and less gnats until eventually there were none! So pleased. Hopefully we won't need to use again but I know what to get if there is a next time.

I've lived in my place for 20 years and suddenly drain flies appeared in my kitchen sink -- I had never seen them before. I believe they got started in drain sludge that must have accumulated over time (the sludge was not think enough to slow the drain, but evidently was thick enough to harbor drain flies). First, I used Drano, it helped, but did not completely eliminate the flies. So after a couple weeks, I ordered this product. After a two days of using it, the flies were completely gone. The flies have now been absent for a couple days. If the flies reappear, I will update this review.Note that I have followed up by using a drain snake to clean sludge in the horizontal drain pipe between the two drains in the kitchen sink -- but I only did that after all the flies were gone. I didn't find that much sludge in this horizontal pipe so maybe the culprit sludge was further down the line. BTW, I used FlexiSnake Millipede drain snake which I highly recommend for sludge cleaning since it's "bristley" (if that's a word!) -- but the Millipede snake is not very long so I may follow up and get a professional plumber to clean the full length of all my drains -- From reading many forum posts on the subject, I understand that cleaning out sludge is the most effective way of really getting rid of drain flies. However, short of that, this product worked quickly for me and was a lot cheaper. I'll save my pennies and have all my drains professionally desludged in a couple months.I used this product as follows on my kitchen sink: First, I squirted a couple ounces down 1) garbage disposal drain, 2) the other sink drain 3) bottom of dishwasher (don't forget that -- since it's a possible home of drain sludge). I then poured just a couple ounces of water down each drain -- enough to wash the gel into the drain, but not enough to overly dilute it. I put silicone mats over both sink drains (the kind you can use to cover bowls in the microwave). I also closed the dishwasher tight and put tape over the little opening of the dishwasher overflow which is next to the tap on the sink (if you do this -- don't forget to remove the tape later). I did this to trap any flies and keep the fumes in so they would effectively "gas" the flies and any larvae. Don't worry, the "fumes" are not strong or noxious at all -- just a mild orange odor that dissipates quickly, but I think these mild fumes may be effective against drain flies when confined to the drain. I left this set up overnight without running any water. Then I flushed the drains and repeated. So far, so good -- no flies. I may do this every month if I'm disciplined! Cheers -- and best of luck getting rid of your drain flies!

Had worse than usual fruit and drain flies. Even though I don’t use the garbage disposal I k is there’s still a build up since the dishwasher line is attached to it. Have used a few times now down both sink drains and have seen a significant decrease of bugs. Smells decent, not too chemically, which is nice. Would rather have just a screw off top versus spigot style, can’t close without getting some on hand. Only real complaint was packaging, which is more on Amazon than product - was in a box with other items, no padding and no bag around bottle to help prevent leaks.

I have purchased this product three times. It was recommended by an extermination company. It helped end a springtime gnat issue in the kitchen drain and clear other household drains.

My roommate swears by the stuff… I’m unimpressed, though it has possibly kept the flies down a bit. It just doesn’t seem to last very long, which means we are buying more of it to use more often, and I feel it’s not really solving a long-term problem. Admittedly, since it’s made out of particularly safe ingredients, it’s actually a bit more effective than I expected it to be.

I had the drain flies that flew up from hell and inundated my kitchen and the rest of my place. They even made their way into my fridge and freezer! Any time I would eat they harassed me and I felt unwelcome in my own home. I bought this after reading the reviews. Treated all my drains in the home including the tub. The next day i noticed a big difference in the amount of demons flying around. I retreated a week later and I haven't seen any. I will gladly treat my drains every month now. I also keep a drain cover over the side that has the garbage disposal which seems to be the gateway. I say try it. Worked for me.

I first got this product last summer because the gnats were so out of control in our kitchen and living room. The vinegar was not working. It worked right away to start reducing the numbers of gnats. I used a second dose, and they were all the way gone. And now, in July of this year, we have had zero gnats. Literally none. Not only does this work, it keeps working. If we get the bugs again, I won’t think twice before buying this again!

Absolutely love this, it doesn't ship to California but i purchase for my mom in AZ and took it back home. My client has a fruit fly problem, poured in his drain. Cleared up in hours.
