Rockwell Labs IBDC032 Invade Bio Drain Gel-1 Qt

I purchased the Rockwell Labs Invade Bio Drain Gel after dealing with recurring drain smells in my kitchen sink and noticing a few tiny drain flies. I’ve tried a lot of basic enzyme cleaners before, but this one is noticeably thicker and actually clings to the inside of the drain instead of running straight down. I followed the directions and poured the gel slowly around the entire rim of the drain at night. By the next morning the sour smell was completely gone, and within two days I didn’t see any more drain fly activity. The consistency is more like a syrup than a liquid, so it coats the pipes really well. I also appreciated that the scent is mild and not chemical or overwhelming. I used it again a week later as maintenance, and it continues to keep the drain clear and odor-free. A little goes a long way—definitely more effective than the cheaper enzyme products I’ve purchased in the past. If you’re dealing with drain flies, buildup, or just constant kitchen sink odors, this is one of the few products that actually works the first time. I would absolutely buy it again.

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!

hands down one of the best drain cleaners I’ve used. The probiotic gel clings to the sides of my drains, digests built‑up organic gunk and grime, and helps eliminate odors and drain flies fast. I noticed a real difference within a day — fewer smells, smoother draining, and no more nasty drain flies buzzing around. I also like that it’s safe for septic systems and doesn’t rely on harsh chemicals. If you want a gentle but powerful cleaner for kitchen or bathroom drains, this is a great choice.

This is my go to for the dread time of the year: phorrid flies and gnats. They work wonders on the drains, toilet bowl , and I even put a drop to clean the ac lines in my apartment! I will always be a customer!

Has not stopped the drain flies yet

This is our go-to to keep our drains clear of gunk. Started using this a few years ago as per our plumber's recommendation. I like that it has the spout on top to make it easier to squeeze into the drains.

Seriously this drain gel is a lifesaver.I have been dealing with a fruit fly infestation for about 3 months now. I had tried everything and was unsuccessful. I couldn't even find where they were coming from!! I felt like I was going insane. I finally read a post someone made suggesting this gel for drains. I never even considered they could be in my drains. I tried boiling water with bleach, baking soda and vinegar and finally gave up. The flies kept coming. I decided this would be my last resort before calling pest control. I had hopes that it would work and it did!! This is just the second day and I have seen a huge reduction in the number I've seen in my sticky traps. One of my traps actually had zero when I checked this morning and it's had at least 5 a day for months. I love this product so much I just ordered a second bottle. I followed the directions of another reviewer and put two ounces of gel down both my sink drains, and my bathroom sink and tub. I then poured two ounces of water down the same drains and covered them overnight. That's it! It's amazing!! I'm so happy!!

This product didn’t work at all for our drain fly issue.
