Rockwell Labs IBDC032 Invade Bio Drain Gel-1 Qt

Rockwell Labs InVade Bio Drain Gel takes a smart, biological approach to pipe maintenance rather than relying on harsh chemical heat. Powered by a blend of specialized natural microbes and citrus oil, this thick orange gel coats the interior walls of your pipes to actively digest organic scum, grease, and food debris. Because it targets the exact organic buildup where drain flies and gnats love to breed, it tackles troublesome infestations right at the root cause while leaving behind a pleasant, fresh citrus scent. What makes this one-quart bottle so useful in everyday maintenance is its sheer versatility and safety profile. It is completely safe for plumbing, septic systems, and municipal waste setups, making it ideal for residential kitchen sinks, bathroom floor drains, or commercial soda fountain drip tray lines. Applying four ounces at a time during low-use hours allows the thick formula to cling and work overnight. It is a powerful, low-effort tool for maintaining clear, odor-free plumbing without damaging your pipes.

Highly recommended for your sink if you have issues with phorid flies. This must have removed a small clog I didn't know I had, because about a day after initial application, there were half as many flies, and it only took another day for them to disappear completely. Following the recommendations on the bottle, I now apply this once a week for maintenance, and the flies are staying away. Very satisfied with this cleaner overall.

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 got the drain flies under control in my kitchen. I used it for 3 or 4 nights before bed and now use it once or twice a week to make sure they stay away. Smells good.

Good and safe

I've been battling a drain fly issue for months and couldn't get it under control, even after trying many recommendations found online. This stuff works - but you need to do it religiously, every night, until you see no more bugs. I'm on week 3, but haven't seen any flies for a few days, so I know my problem is nearing the end. The bugs persist after the treatment because this does not kill them - it dissolves what they are living on. I would not bother with this size bottle (there's a bigger one) because treatment for a week probably won't fix the problem. ChatGPT was very helpful with suggestions, including putting some into the dishwasher.

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!

Worked as stated, after 1st use.
