Gentrol Concentrate IGR Insect Growth Regulator 10x1oz ZOE1006B

My apartment building has a German roach problem and it didn't take long for me to have one as well. I contacted a professional pest control company to spray monthly and they eliminated the problem in the first month. I asked all the technicians they sent what they use and they were happy to tell me! They all emphasize how critical an IGR like gentrol is for roaches and paired it with alpine WSG. My yearly contract with them is up and I have been spraying that mixture for months on my own. I have not seen one and as far as I know the building still has a problem. I highly recommend this especially paired with alpine WSG.

Combined with Alpine and sprayed my whole house. Now I'm COMPLETELY roach free!

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!

I use the little bottles of Gentol ,10 1oz bottles. I followed the directions and sprayed in every corner of the house and under sink , behind frigerator, and stove. Same in bathroom and laundry room. Soon I saw deformed roaches with bent wings. I also use roach traps and insecticide. I am now not losing the battle. Compared to what professionals exterminators wanted to charge. I have only been using it for a month and I can see a difference.

Read about this product on Reddit and mixed it with alpine wsg and it absolutely did the trick! Bought more than I needed but will not be dealing with those little cockroaches again!

One bottle of Gentrol mixed in a gallon sprayer of water with pre measured Demand CS and you won’t have roaches. Listen, if you have one roach, you have a roach infestation. Just because you don’t see them all doesn’t mean they aren’t there. They are there you can trust that. Gentrol gets rid of hard to get rid of bugs, like German roaches. They are very hard to get rid of. I have had my house for almost 8 years. I spray every 4 months and have never once seen a bug in my house. Don’t listen to anyone who says every house has roaches. Not houses who use this stuff on a regular basis. Spend the money, buy the one shot of Gentrol and some Demand CS and your roach problem will be a distant memory in no time flat.

Gentrol is a great product. My only complaint is with how it was shipped. The bottles come in a thin, flimsy Gentrol box, which is fine if you're buying it off a shelf. But to be shipped that way is negligent with a product like this. It was shipped to me all the way to South America in a small typical Amazon shipping bag. Those are fine for all kinds of products, but not this product. They offer very little protection. This is a liquid product. The lids on the bottles aren't sealed, and being shipped in just a thin bag, the box was crushed and all of the bottles were scattered in the bag, and one of the bottles was leaking. I could smell the product strongly, and the crushed, open box was saturated with it.

I moved in with an apartment with an german roach infestation in the kitchen. I tried, baits, sprays, and the pest control company came out to spray. I did some research I came across this product and paired it with temprid fx, alpine gel, and boric acid based on the other comments. I have only seen 1 roach in a month. It did take a few days to work, but it does work.
