## Overview

Gentrol Insect Growth Regulator (IGR) Concentrate is a powerful pest control solution designed to prevent roaches, drain & fruit flies, bedbugs, and stored product insects from reproducing. Its active ingredient, Hydroprene, disrupts pest development by stopping larvae from maturing into breeding adults. Ideal for use in both food and non-food areas, this 1 oz concentrate penetrates deep into cracks and crevices, reaching hidden pests other treatments miss. With a shelf life of up to 3 years, Gentrol IGR is a reliable, long-term addition to any professional pest management strategy.

## Description

Gentrol IGR Concentrate travels deep into wall cavities, cracks and crevices, reaching the stored product pests that other treatments miss. Hydroprene, the active ingredient, prevents stored product pest larvae from progressing to the pupal stage of development, so the larvae die before they become breeding adults and future infestations. 1oz. bottle. Gentrol Concentrate should never be used to eliminate a roach population by itself. Gentrol will not kill roaches...it only prevents them from reproducing. You should use roach baits and roach sprays in conjunction with the Gentrol Concentrate.

## Questions & Answers

**Q: Can you use it right before heat treatment?**
A: Once I used this all roaches were gone in 90 days.   No need for a heat treatment.  Been a year since using and still roach free.  Best advice, get a gallon jug with a spray wand and spray it in every crack and corner.

**Q: How many bottles do you get?**
A: 10

**Q: How much does the one ounce make?**
A: You mix one ounce of this concentrated fluid to one gallon of water.

**Q: How many bottles per room ?**
A: Each bottle is mixed into a gallon of water.  You spray all corners cracks and crevices.  A gallon will go a long way.  We had roaches for 10 years and tried everything to get rid of them. Used this once 2 years ago and after 3 months I haven't seen a roach since.

### ⭐⭐⭐⭐⭐ ALL ROACHES GONE!
*by A***R on October 26, 2020*

I am doing to try to make this short and to the point. Buy this product it will not disappoint. I had a brother and his family stay with me for a year, 2009 to be exact, and with their bedroom furniture they brought roaches. He moved out in 2010 but I spent years buying every roach spray, gel, fogger, fumigator you name it. Nothing worked. I even moved out the house for 3 days and fumigated once evert day. But the roaches always came back. I tried a pest control company for a year. Did not see a difference so i let them go. Then I found this product. In combination with the Gentrol Point Source Disks, I noticed deformed roaches within a week, noticed that roaches were no longer seen in bedrooms within 2 months. Then 6 months later during our covid isolation, my wife mentioned that she hasn't seen a roach in a while. I confirmed. i looked in all the cabinets and usual roach hiding spaces and found none. This was back in June. It is now almost November and we have not see a single roach in our house. Only problem is I think I bought too much of the product because I only used 2 bottles of the 10 supplied in the case I purchased. I have making solutions for family and friends after touting my success. Now 11 years later my house is finally roach free. I vouch for this product if you cant tell by now.
