How Gentrol Point Source Works Gentrol Point Source is labeled as an insect growth regulator, or IGR. It contains the active ingredient hydroprene and targets the larvae and the eggs in the treated area. Hydroprene is useful in a roach prevention program in which it's important to prevent an infestation from happening. Because it's an IGR, this ingredient disrupts the life cycle of insects and stops them from being able to reproduce. It doesn't kill the insects; rather, it affects their ability to continue populating the interior. It also works on adult roaches, including other insects such as pantry pests and drain flies. It's recommended to use Gentrol Point Source as part of an integrated pest management program in conjunction with contact and residual insecticides. While the insecticide kills the pests, Gentrol will act as a birth control for the remaining survivors and keep the populations under control in the treated area. In fact, the roaches won't have to contact the Gentrol station at all since it releases hydroprene particles that will move into a concentrated area. Where to Use Gentrol Point Source Use Gentrol Point Source IGR in areas where roaches and pantry pests have infested. Place a Gentrol station in closets, pantries, drawers and other confined spaces to target the insects and to reduce the population. It can also be placed around plumbing pipes to affect the insects as they leave or come in from the outside. Gentrol Point Source works well in ductwork, utility closets and similar places where the insects like to hide. It should not, however, be used outdoors to control insects. Some common areas for use include: Homes Food-handling establishments Hospitals Warehouses Restaurants Hotels Target Pests Gentrol Point Source is labeled for roach control, including the control of pantry pests such as confused flour beetles. Stored products pests like merchant beetles and Indian meal moths are also affected by the active ingredient. Use Gentrol to target the following pests and more: Drugstore beetles Saw-toothed grain beetles Rice weevils Cigarette beetles Although it's not labeled for bedbugs or fruit flies, hydroprene can and does affect these pests in the same way as other labeled insects. However, do not rely on Gentrol for the direct control of bedbugs as they are resistant pests and require more than an IGR for complete elimination. Reasons to Use Gentrol Point Source Acts as a birth control for roaches and stored product pests Safe to use in sensitive areas like food-handling facilities Easy to set up and no need to spray the target space Provides 90-day control and works well in IPM programs Halt Roach Production With Gentrol Point Source Control roach populations and other pest infestations with Gentrol Point Source. It works for up to 90 days and doesn't require spraying equipment. Set it up in the target area, and let the active ingredient do its job. Gentrol prevents roaches, fruit flies and stored product pests from breeding and increasing their numbers. Use it with an adulticide for total indoor pest control in homes and businesses.
