Gentrol Point Source IGR is an easy-to-use Insect Growth Regulator disc that effectively breaks the life cycle of targeted pests. It can be effective for up to three months, offering long-term control of cockroaches and some stored-product pests.

Gentrol Point Source IGR discs, manufactured by Zoecon, are an easy-to-use insect growth regulator for long-term control of cockroaches and some pantry pests. Gentrol Point Source comes in disc form rather than in a spray, allowing for easy set and forget treatments of high-activity areas.
Gentrol Point Source plastic disks do not require roaches and pantry pests to come into contact with them. Instead, the IGR is released and slowly translocated in an area of up to 75 square feet, making this an excellent option for treating areas where spraying insecticide is not approved or convenient.
Gentrol Point Source discs contain hydroprene, a synthetic juvenile hormone imitator used to disrupt the regular growth pattern of the target pest, preventing them from maturing into adults. This will also sterilize adult cockroaches so that they can no longer reproduce. You will know it is working if you start to see cockroaches with crinkled wings after applying Gentrol Point Source.
When used in a complete cockroach control program, Gentrol Point Source helps stop the endless cycle of reproduction that makes a cockroach infestation so hard to beat.
Tools Needed
You do not need additional tools as they come ready to use from the package.
How to Use
- Step 1: To use Gentrol Point Source, determine how many disks you need by measuring the square footage of your target areas. Measure the length and width of the treatment area in feet, then multiply them together (length X width = square footage). Gentrol Point Source can cover a range of 75 sq. ft., so depending on the areas and different rooms, you may need multiple.
- Step 2: Gentrol Point Source features a cotton pad housed within a plastic encasement with a small capsule on the side of the disc. This capsule holds the chemical. Press firmly between the thumb and forefinger on the capsule to activate it until a snapping sound is heard. Once you hear a snap, the contents of the Gentrol Point Source capsule have been released into the cotton pad, which will then be released into the localized treatment area.
- Step 3: The Gentrol Insect Growth Regulator Discs can be placed vertically or horizontally in areas where you have seen pest activity, such as pantries, cabinets, drawers, and around voids. Do not place them in areas accessible to children or pets.
Where to Use
Gentrol Point Source IGR discs can be used anywhere, even in sensitive areas where food is stored, including food handling establishments. However, the disk must not be placed on food serving surfaces and should be kept at least 3 feet away from exposed food.
Its sticky back end allows it to be placed on walls, in drawers, cabinets, and other hard-to-reach and hard-to-treat areas.
When to Use
This product should be used when you have a cockroach infestation in the home. Cockroaches breed and make eggs at an alarming rate, so Gentrol Point Source helps to prevent eggs from hatching, a new generation from developing, and an infestation from growing. It also helps to make the adults sterile so they can't reproduce.
Safety Information
Gentrol Point Source is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when handling and applying this product.
Keep it at a minimum distance of 3 feet from exposed food.
Special Considerations
Gentrol Point Source is sold in increments of 20. It may take a couple of weeks before you begin to see the initial effects of the Gentrol. Using Gentrol Point Source alongside an adulticide is recommended for faster and more effective control.

Time to Kill | Gentrol Point Source IGR does not kill the insect. It acts like birth control for bugs by interrupting the development cycle of the insect. Insects that are born from a treated adult will have deformed reproductive organs and not be able to reproduce. It is best to combine Gentrol Point Source with a adulticide for immediate control. |
