Rockwell Labs Invade Hot Spot+ Bio Foam 19oz.

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!

Good product.

Best way to organically clean the gunk out of drains. Removes a food source for drain flies. Just make sure you get the optional hose to put down the drain. The included red tiny tube is insufficient.

It came next day and seems to have cleaned the drains like it says. It is messy. the little plastic dispenser wont stay in the can and makes a mess. However seems to have cleaned the drain. might want to wear some gloves.

This stuff works the best for fruit flies.!

Difficult to use

I previously bought two of these. It seemed to work ok. But I had problems with the straw to direct the foam to the right place. It kept popping off. Had to hold it in place with one hand while pressing the button with the other hand. Awkward. Not only that I thought it might go down the drain and cause a plumbing expense. . I thought it was a defect of that one can. The drain flies came back so I ordered an additional bottle to have on hand. Then I started using the second can from the previous order. Not only did I have the same problem but because the straw did not stay in place it kind of exploded while I was trying to spray it and hold the straw in place at the same time. Got it all over me. It happened two more times and got it in my eyes. Won’t use it again. And I have the new bottle sitting there I got as a backup. And it’s not returnable. Would not recommend. Saw at least one other person on here that had the same issue.

I had clogged bathroom sink and was procrastinating on getting it fixed because it was still draining but very very slow. Somehow, I started seeing these flies in my bathroom. I didn’t think much of it and just killed them when I see them . Then one evening, I turned on the water and I see little worms floating in my sink. They were still alive and squirming. I was so grossed out. Tried to suffocate them with Comet cleanser but they did not die. Looked up on internet and found out they were drain flies. And those were the larvaes. They’ve been laying eggs in the drain. My home made solution was pouring a mix of hot water ,salt, vinegar and baking soda in the drain . I thought that worked for a day but I still see one or two grown flies flying out of the drain. I ordered this product while still using my home solution until it arrived. I used it twice a day, before I go to bed and in the morning before I leave for work. After 5 days, no more drain flies!
