ZOECON Gentrol Insect Growth Regulator (IGR) 16 oz Can (WELL15100), Packaging May Vary

Two years ago my daughter begged me to allow a homeless friend of hers to move in to our home. In typical no good deed goes unpunished fashion she brought German roaches with her. We saw the first roach a couple weeks after she moved in and the kept getting progressively worse. We are not dirty people but tI still could not get rid of these bugs. I literally tried everything in the local market. I spent well over a 1000 dollars on bug bombs sprays baits and gels. each one would reduce the number of bugs for a short time but they never went away and then after a short time they were back. I tried calling professionals but they just tried to rope me into a one year expensive "abatement" contract where they were unwilling to promise results. A friend told me about combining Advion Cockroach Gel with Gentrol (buggy birth control). I put down new advion and sprayed Gentrol every week for a month. When I first used advion I actually saw more bugs for a week but they were zombie bugs. Staggering around even during the day and eventually dying. They were easy to step on because they were slow and disoriented. So I would recommend timing it so you have at least 2 weeks with no guests. But by week 3 I was only seeing them if I looked really hard,and it was a bad infestation, so bad I was ready to sell my house. I have not seen a single bug in a week. It is like I can finally breath again.I can not say if this would work in an apartment unless you treat the whole building. But this defiantly worked for my house. But again it is the combination of advion and gentrol that gets the results. Advion kills most of the roaches even resistant ones. The gentrol keeps the eggs from hatching and makes the few that survive the poison sterile so it does not start again.

Very effective!

Bought this for drain Flys. It works great. Don't be confused this is not an insecticide. It does not kill anything unless perhaps you drown the bug in it. Paid big money for an exterminator and he sprayed this in the wash tub drain and the washing machine drain pipe. He left the can with me and told me to spray it in the drain for three days. The drain flys disappeared. After capturing hundreds of flys on fly tape day after day using this stuff worked and no more flys on the tape.Again this is not an insecticide, does not kill. This stuff mess with the ability of the fly to grow and breed. No breeding equals no flys. This kills the flys because they can't grow into adults.This stuff works, I bought this directly because some flys reappeared after several weeks and this stuff did the trick again. Now I plan to spray in the washing machine drain pipe every month or so.Hope this helps.

I have been using this for the past month, in concert with both Dupont Advion Cockroach Bait Arenas all over my kitchen, and also taking action to block all the more obvious entry points into my kitchen from which bugs tend to appear. I put away all foods & food preparation tools in my kitchen, covered most surfaces with sheets, and did a good spray. Then left all the apartment windows open over night and slept elsewhere.I have to say this stuff smells utterly toxic, despite all the notices about how it's harmless for humans/animals and ok to use in kitchens etc. And after handling the product for the spraying some of my skin tingled and felt numb. But I went and took a good long shower and felt fine the next morning. The next day there were no odors in my apartment.In the first week there were many dead adults laying in the kitchen; after 2-3 weeks I was not seeing any more full grown adults, only babies. So I assumed that this IGR spray was slowly taking effect.Because I was still seeing some bugs around after 2-3 weeks, I also started leaving another product out a bit (Harris Roach Tablets), which I'd held back on up to this point, because I'd read that this Advion was better for bringing long term killing back to the nests. As opposed to these tablet which only kill the bugs that eat it (and which baby roaches can't always chew on properly).And now, 4 weeks later, I am not seeing any bugs at all. Success! But I cannot be sure which product did the most damage. A multi pronged approach is definitely recommended. Remember, this IGR is not a bug killer, it's a bug growth/development inhibitor which if they come in contact with it, prevents bugs from becoming healthy egg-laying reproducing adults.We shall see how much longer this spray is effective in my first application. I don't really savor the thought of having to do any more applications to be honest.

I had a roach problem in my kitchen and used this along with the Advion paste and haven't since a roach since. I went to a pest store and this product was what was recommended by the sales agent at the store. It came in a nice package along with instructions on how to use this product. The can comes with a red straw and was very easy to use and dispense. Of course it was a lot cheaper purchasing this product on Amazon so I ordered it. I cleaned out all the cupboards and clutter on the countertops and sprayed the gentrol growth regulator all around my kitchen and in my cupboards like the instructions tell you and then I placed drops of the advion paste around the back of the cupboard, counters and floor. This stuff works excellent! I have not seen a roach in months (thank goodness). I only used about half of the can so I have plenty left to use in the future if needed. The instructions say to use this product once a year which I will defiantly do. This product saved me so much money from hiring an exterminator. I highly recommend this product for anyone who has an insect problem in their house. This stuff is amazing!
