Product Overview

Gentrol Point Source is a special Roach control device that contains the Gentrol Insect Growth Regulator (IGR) hydroprene for 90-day control of roaches and other stored product pests. Activating Gentrol Point Source is as simple as squeezing the raised end of the plastic, adhesive-back device. This releases Gentrol IGR onto a filter paper. From there, it moves up to 75 square feet, damaging adult roaches and preventing them from reproducing. 20 units per box.  Gentrol Point Source should never be used to eliminate a roach population by itself.  Gentrol will not kill only prevents them from reproducing.  You should use roach baits and roach sprays in conjunction with the Gentrol Point Source.

How Gentrol Point Source Works

Gentrol Point Source Stations discreetly release microscopic particles of the active ingredient Hydroprene into the treatment area once activated. Target pests do not need to contact the device directly since the active ingredient moves into a localized area. Hydroprene is a biorational Insect Growth Regulator (IGR) – similar to insect growth hormones that occur naturally in roaches and stored product pests - that disrupts the life cycle of certain insects in the egg and larvae stages of development, essentially making it a type of birth control for insects. Gentrol Point Source Stations do not act as an adulticide, so they should be used as part of a broader Integrated Pest Management approach. The IGR helps to keep target insect populations under control, which is especially useful in areas where conventional sprays and foggers are not appropriate or where baits are less effective due to competing food sources. Gentrol Point Source helps to achieve more rapid results than using adulticides alone since surviving insects are not able to re-establish the population.

Gentrol Point Source Target Pests

    Excellent at bringing an infestation to an end

    By Rob on 05/09/2014

    Verified Purchase

    I have used Gentrol Point Source in combination w/Demon WP and Dupont Advion gel bait to bring several infestations to an end over the years. I do maintenance on a number of apartments and these three products, when applied together, will stop an infestation dead in its tracks. I used to pay for an exterminator but once they failed to stop an infestation after 3 treatments I started treating myself using these products and I save $$$ by doing it myself. And I have had some really bad infestations where the roaches were falling off the tops of doors, coming out of plumbing / electrical penetrations in the walls, and on the walls during the day.

    Great Effective Products

    By Lucinda on 02/03/2013

    Verified Purchase

    I live in a apartment that when I first moved into had a German Roach Problem. When I went on a massive detail house cleaning, first I found that previous tenant, well.. were'nt the cleanest of people. After getting all cleaned I DID have professional come in to help start the getting rid of the problem. Once I saw them slowing up , I dicided to do MY OWN Pest Control. I found this site and ordered my own home defense. I ordered the Advion Roach Bait and the Gentrol Point Source. AMAZING!!.... It was like the bugs just disappeared completely. I would see one every once in a while but it would be just barely alive. I like that I am able to control where baits and gentrols are placed since I have a small pet and I can be secure in knowing he does not have access. I HIGHLY recommend these products to anyone, products work fantastic, they are easy to use, totally worth purchasing. I Have ZERO bugs since using this product.

    Effective and painless

    By Karla on 05/14/2014

    I'm a girl and I hate roaches. I started seeing roaches on the kitchen counter every night. Found this site, and bought the Gentrol and the Max Force Bait gel. Then, 1) Spent 6 hrs cleaning the kitchen -insided refrigerator, emptied every shelf, oven, stove top, counters, floors. Wiped everything w/diluted Pinesol. Discarded open sugar/pasta/flour containers. 2) Squeezed tiny dots of Max Force every few inches inside cabinets, dishwasher, under counter, around floor. 3)Put 1 Gentrol in each full cabinet. 3 days later, started finding dead roaches, 3 medium-big INSIDE dishwasher. Very happy. Tip: professional squeeze gun not needed at all. Just use regular inc. plunger.

    Great Stuff!

    By Marie on 05/25/2012

    I live in Florida where roaches can be a real problem. I was infested with German Cockroaches. After a deep cleaning (roach feces is nymph food) and placing Max force gel bait to kill the adults, I place Gentrol around my house where the roaches seemed to be vacationing. It's been 1 month now and I can say I think I have won the war of the roaches, I highly recommend this product.

    Great product!

    By E.k. on 04/09/2008

    Gentrol Point Source has worked effectively for me for years. When I start seeing roaches I check the date and three months have passed. It isn't easy to control roaches in Florida. Great product.

Questions & Answers

Sort Questions
I have seen deformed roaches carying egg cases months after I have treated some areas..

Since this is a growth inhibitor, how is it mature deformed roaches have the capacity to reproduce? What happens to the nymphs that hatch from these egg cases or is it that the eggs do not hatch? A roach is a roach, deformed or not. Please, I'm confused!

Gentrol Point Source Stations will cause the roaches to become deformed. It also will prompt the females to prematurely lay their eggs (the eggs will also be affected by the product). It sounds like the product is working and doing exactly what it should. If you need additional information on the product or roach control, please contact us at 866.581.7378.

What if my cats walk on areas where Gentrol Point Source may have landed then groom themselves?

I am using Gentrol with bait stations for an Oriental roach issue we are having. One of the places they have been seen is an area where my cats have their litter box. If my cats walk on the formula the Gentrol point disk emits, and then lick their paws, is this harmful? I don't see this addressed in the enclosed information.

The tiny minute amounts of Gentrol the cats would pick up on their paws would not cause any issue whatsoever. According to the MSDS "Due to the unique nature of the product form, acute toxicity hazards are not anticipated". This means that unless the cats actually get a hold of the disc and eat the vial inside before it is crushed, there would be no concern that they would ingest enough product to cause any type of toxicity issues.

Our bathroom and kitchen share a wall so they are close. Should we use a Gentrol Point Source in both places?

Also, you are supposed to keep them at least 3ft away from food. Our kitchen is small so where can we place one? How long should we wait to come back in the house? Can we use one in the car for carpet beetles or will it be too concentrated? When you press it, does it immediately release into the air you breathe? I'm pregnant, so we really want to be safe.

You should place a Gentrol Point Source disc in each room. For the kitchen area, you can use the sticky tabs included in the package and place the disc on the side or behind the fridge or place it to the side of the cabinets or pantry. You only need to keep the disc away from food prep areas not from stored food product. According to the manufacturer, there is almost no hazard from inhalation. There is no need to leave the house when using the Gentrol Point Source discs. Gentrol Point Source is labeled to be used in modes of transportation, but we have not heard of any one using it in a car. To get rid of the beetles in your car you should be able to thoroughly vacuum and spot spray a pyrethrin product such as 565 Plus into cracks and crevices.

Will constant air limit Gentrol Point Source ?

I sometimes open doors/windows for fresh air. Also have fans running. Will this limit the 75sf coverage area ?

Gentrol Point Source works best by having some air movement. We recommend placing them up high so that the product can "flow" down over the given space. Occasional open windows or doors should not have a negative effect on the product.

What is the difference between using Gentrol Point Source and Gentrol Concentrate?

I have a residence and problem with roaches. The liquid is a better price and seems to be able to cover more areas-- but is it not as strong as the point source?

The Gentrol Point Source and the Gentrol IGR concentrate are going to provide the same results  for roach control. The Gentrol Point Source are great for situations when spraying is not allowed and this formulation is also very convenient as there is no mixing or spraying required. The Gentrol Concentrate on the other hand is definitely more economical.
