Rockwell - IBDC128 - InVade Bio Drain Gel -1 Gallon

I will try and keep this review short and hope that it helps you with your gnat problem. I came home from work one day, last September, and noticed a few gnats, but didn’t think too much about it. I had never had a problem with gnats, I never dreamed I would spend a year trying to get rid of them. I bought some window adhesive strips and put on the window in the bathroom, that is where I saw them. Within a week of that they were growing in numbers. I first tried bleach, then tried using baking soda, salt and vinegar for months, that didn’t really help. I wasn’t sure which drain they were coming from, be it the shower drain or sink drain or both. As time went on the gnat problem was growing. It’s now 5 months later and still have the problem. I called a plumber out, he said, Oh, you need to call a pest control company. I called a pest control company and he said use Vinegar, salt and baking soda. LOL I went back online and purchased a KATCHY Indoor Insect Trap: Bug, Fruit Fly, Gnat, Mosquito Killer - UV Light, Fan, Sticky Glue Boards Trap Even The Tiniest Flying Bugs - No Zapper. This worked great! Well, I thought it fixed the problem. But no, gnat problem didn’t go away, because I had not gotten to the root of the problem. It’s now 8 months later. I went online and read and read about gnats. What I was learning was that I need to get rid of the larvae in order to get rid of the gnats. I found Rockwell IBDC128 InVade Bio Drain Gel. This is a great product. It really cleaned the walls of the drain, but still didn’t get rid of the problem. Next product was InVade Hot Spot Bio Foam. This is basically the same product as mentioned earlier (Rockwell IBDC128 inVade Bio Drain Gel) but it’s in foam form. This is a great product, it allows you to turn the can almost upside down, to spray foam in your drain. Doesn’t take much, so it last longer. But, unfortunately that didn’t get rid of the gnats. So, went back online and searched again for something to help me with this problem. Next product I found was Gentrol Concentrate IGR Insect Growth Regulator 10x1oz ZOE1006B and Green Gobbler Fruit Fly Goodbye Gel Drain Treatment | Drain Fly Killer | Fruit Fly Killer | Drain Flies Treatment | Fruit Flies Treatment | Drain Fly & Fruit Fly Eliminator, FINALLY I found something that was getting to the larvae. That is what Gentrol Concentrate IGR Regulator does. It kills the larvae. It doesn’t kill the adult gnats though. You will still have to deal with the adults until the product has successfully killed all the larvae. This can take as much as 2 weeks and then a week or so of treating the problem to make sure it doesn’t come back. The key is to treat the larvae everyday. Thank goodness I found Gentrol and Green Gobbler. I mixed the Gentrol with the Green Gobbler in a 16 oz squeeze bottle. Use gloves when handling this. It took 1 month after I started using it. I can’t say enough about Green Gobbler and Gentrol Concentrate IGR Regulator along with the KATCHY machine. They have successfully gotten rid of the gnats. You may not have the problem as bad as I did, but I wish I could have had this information to help me figure out the fix for the gnats. Lots of luck!

Awesome stuff, I had a drain fly infestation, i tried bleach down the drain with hot water, i tried just about everything. Fruit fly traps you name it, i could not get rid of these drain flies. This is the only product that actually started working on day one. Yeah there were some flies left but you have to do this for 5 to 7 days every day 4 ounces per drain in the house. In my case i did every drain. I am continuing to do it for 7 days which means i need about 6 gallons. Pricey but you get what you pay for and if you are at the point of no return with drain flies this is a minimal cost to pay to get rid of them. I will be buying this stuff once a month after i go through the 7 days. The idea is to maintain the drains after the treatment to ensure these pests don't come back so it recommends monthly maintenance. I had a pest control guy basically tell me that he couldn't help me and recommended the bleach method. Well if you search about drain flies online everything points to this product and everything i read said bleach dont cut it, it does not break down the things they eat which is organic matter. This product is an enzyme and will break that down and keep your drains clear. Two benefits in one no bugs and no stopped up drains im sold!

I used this to kill the drain flies in a shower on the lower level of our home. I used the entire gallon over a period of 3-4 weeks following the instructions of using it every other day. Initially it killed appeared to kill all of them & the larva, then a few weeks later I started seeing one or two come back so I ordered a second gallon. I used it every day instead (based on a you-tube video) for about a week or two and now have used that gallon about half up and also poured some white vinegar down the drain. Hopefully the drain fly larva is gone, I can't see spending another $30 again when this gallon is used up.

I had a problem with drain flies in 2020. I tried Drano, bleach (not at the same time as the Drano) and boiling water. Nothing got rid of them! Then I was away for six days so no water used in the two bathroom sinks and they disappeared. Well, they showed up again about six weeks ago. They are so annoying!! So I researched other remedies and found this product. After the first night, there was a greatly reduced number of these pests. I use it every night, 1/2 cup down the two master bath sink drains, shower drain, and also in my hall bathroom sink drain. Tonight will only be my fourth night using it and I only saw a few tiny ones. I am soooo happy! I am OCD about having a super clean house (no shoes past the front door) so having a bug invasion of any kind is upsetting. I'm going to keep using this for the next 10 days and then use it once a week and hopefully they will all be gone. I already purchased my second gallon. I did not notice much of a scent. Update: April 28, 2023 The drain flies are back. :( I started using this product again. I also pour boiling water down each of the two sink drains in my master bath prior to pouring the Invade gel down the drain. Then I close the drain so nothing can get in or out. I do this two or three times in a 24 hour period. Within five days there has been a great reduction in the number of drain flies. I ordered another gallon and it's a light yellow -- not orange like the previous one. I haven't used it yet but will hope whatever the change was in the ingredients that it's either the same or better than the previous solution.
