## Overview

ZOECON Gentrol Insect Growth Regulator (IGR) 16 oz aerosol uses 0.36% Hydroprene to disrupt the reproductive cycle of cockroaches, bed bugs, and stored product pests. Its visible foam and precision extension tube enable thorough coverage in diverse environments—from residential homes to commercial kitchens—making it a trusted solution for long-term pest management.

## Description

Control insect growth regulator disrupts the normal development of immature cockroaches, bed bugs and stored product pests. Gentrol aerosol will make adult insects incapable of reproducing and will disrupt the insects normal life cycle making 100% control much more achievable than programs in place without it.

Review: Great Product, Terrible packaging - Gentrol itself works very well—the product does exactly what it promises when it comes to eliminating bugs. I was really pleased with the results the first time I used it. Unfortunately, the packaging ruins the experience. The last two cans I purchased stopped working while still more than half full. The sprayers simply would not release any product, no matter how I tried to fix them. At $23 per can, this is unacceptable. Not only is it frustrating to pay for product you can’t use, it’s also incredibly wasteful to throw away half-full cans. For something marketed at a premium price point, I expect more reliable packaging. Gentrol is effective, but unless the company improves the quality of the cans and spray nozzles, I can’t recommend it. Customers shouldn’t have to gamble on whether or not their can will actually work.
Review: Saved my home!!!! - 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.

## Questions & Answers

**Q: Can you use Boric Acid over/with this. How?**
A: IGR=Insect Growth Regulator.  This will be consumed by adults and carried back to the nest where all the nymphs/babies are.  The babies and others will eat the frass (aka, roach poop) and ingest the IGR, which stops them from growing and becoming sexually mature.  This IGR works at an extremely low concentration (parts per billion I believe?) so what I'd do is use the IGR for several days to ensure the IGR has been consumed and the IGR has had a chance to spread throughout the entire colony, then use another fast acting poison to knock out the adults such as Maxforce or Boric Acid if that is what you prefer.  Just pick your poison and follow the instructions on the box.  Or you could use something like Abamectin which is simply a mold/fungal growth.  This is a slower acting roach poison that the adults eat and it takes a few days to kill the adults, but once they die the other roaches in the colony eat their dead, and spread the poison around the nest even more.  When it comes to taking out roach colonies, you need an IGR or your going to probably end up killing most of the adults, and then the problem will return once the nymphs grow to the point that they start leaving the next in search of food.  And you need a slower acting poison so the adults can return to the colony and spread the poison.  If you don't get the poison back to the nest you're just performing a quick and temporary fix.  You never know what is infesting your neighbors homes either.  I started using Bifen to treat my entire yard for flying/biting bugs and it lasts for about 3 months.  Most roaches don't really fly, so they wouldn't survive the trip from a neighbors house to mine so besides killing mosquitoes and gnats and such, it prevents neighboring bugs from reaching my house.  It also significantly reduces the amount of bugs that get into the house from lights around the entrances.  Probably more info than you wanted, but it works great for me.

**Q: Does this spray can come with a thin straw for crevice application? And how long does it say one application lasts before you need to reapply? Thanks!**
A: Greetings Yes about a 6in long also how long does it last, a long time until I see bugs againIf you see roaches and their wings are spread apart, then you know Gentrol is working.I have been using it for years and it works super well after you use roach sprayI also use the Gentrol source device, like a stick on you break a tube inside and it lasts for at least 6 monthsGreat product, well worth the price and long lasting, does the job it was designed to do.Regards

**Q: Does this product controls fleas?**
A: I think all these answers are wrong.  Some are just regurgitating the label. IGR is a phenolic which acts as a hormone inhibitor preventing larval insects from developing the tooth needed to break out of the pupa. Any insect that goes through a pupa stage s/b controllable with IGR.  It's the only real solution to fleas but it takes one life cycle to become operative since larva not exposed will still hatch out of the pupa stage.  Most of all do not accept flea pet meds from your vet.  This particular product appears to be mislabeled for bedbugs.  Bedbugs do not go through a pupa stage.  They are in the spider family.  It could be that this is an IGR combined with an adulticide which also kills bedbugs.  Personally I would stay from adulticides since they are mostly all toxic.  I've used the Archer product with excellent results for fleas.

**Q: How long does this can last?**
A: I have mine for a long time used to I kichen ones a month and I will have 3/4 of a can left.
