Gentrol IGR Concentrate:
* Contains the insect growth regulator (IGR) hydroprene, which disrupts pests’ normal growth pattern.
* The only IGR labeled for use as a spot and crack-and-crevice treatment in all areas of food handling establishments.
* May be applied as a general fogging agent or general surface spray.
* Long-term control – 120 days.
* Breaks the endless clean-out/reinfestation cycle.
* Also targets cockroaches.
Gentrol IGR Concentrate travels deep into wall cavities, cracks and crevices, reaching the stored product pests, drain and fruit flies and fleas, that other treatments miss. Hydroprene, the active ingredient, prevents pest larvae from progressing to the pupal stage of development, so the larvae die before they become breeding adults – and future infestations.
Stored product pests encounter hydroprene the same way they encounter insecticides – traveling on or rubbing against a treated surface. Gentrol IGR Concentrate spreads out from its point of application, creating a much larger treated surface than conventional insecticides.
Whether it’s used as a fogging agent or general surface spray, the long-term control of Gentrol IGR Concentrate is ideal for these sites:
Food Handling Establishments
Aircraft, Ships, Trains, Trucks
Gentrol IGR Concetrate for BedBug Control:
Directions for Use:
GENTROL, an Insect Growth Regulator (IGR), is a synthetic juvenile hormone "look-alike" which disrupts the normal growth development of bedbugs and roaches. Bedbugs and roaches exposed to the GENTROL IGR Concentrate will become adults incapable of reproducing, thus ending the cycle of an infestation. Use GENTROL IGR Concentrate in apartment buildings, hospitals, hotels/motels, residential homes, nursing homes, and marine vessels.
Mix GENTROL IGR Concentrate with water and apply with spray or hand application equipment, such as handpressurized or power-operated sprayers capable of delivering spot or crack and crevice spray applications.
For spot and crack and crevice preparations:
Use 1 ounce of GENTROL IGR Concentrate to 1 gallon of water. Partially fill the mixing container with water, add the GENTROL IGR Concentrate, shake or stir, and fill to final volume. Use diluted solution within 48 hours of mixing. Shake or stir before each use.
Spot and Crack and Crevice Applications:
Apply GENTROL IGR Concentrate diluted spray solution using either a pressurized spray system capable of delivering a pinpoint or variable spray pattern or a device capable of coating evenly. Make crack and crevice applications directly to areas such as crevices, baseboards, floors, ceilings, or walls. Make spot treatments to areas such as storage areas, closets, doors, and behind and under furniture and beds. To treat bedbugs, apply to harborage points mentioned above; in addition, under beds, bottom side of box springs (do not treat linens and mattresses), under and behind night stands, to points where carpet and wall meet, cracks in cove base, molding, and other areas where bedbugs harborage.

This product works! Thank Goodness!
By Eve on May 16, 2010
My sons roommate picked up an old sofa-bed for his room. It had bedbugs! My sons house became infected before anyone knew what happened. No one in our family had ANY experience with these horrible creatures! He ordered from your company and was pleased. Then, the little buggers found their way into MY house, probably because while he was treating his house, we kept our granddaughter with us, of course bringing along some clothes and toys! They really got after my husband because he has a very warm body. We ordered your product and are very pleased! We haven't seen any bugs in 3 weeks, I have one more spraying to do. You should spray at least 3 times, 10 days apart. The odor was affordable, the directions good, and best of all, IT WORKS!

I used this stuff to get rid of bedbugs -- it's the only thing that really worked because it's a genetic disruptor and breaks their life cycle. It had the added bonus of breaking the life cycle of every other insect also -- so I haven't seen a roach or a fly ever since I used it. What an awesome product.

It's just works!
By Kahina on October 22, 2010
This stuff works! I'm soooo glad to have found your website and to have found something that actually works immediately. I just moved into an apartment the 1st of this month where it unfortunately had roaches. I couldn't sleep when I noticed the apartment had them; I'd never lived with these ungodly creatures before. I purchased this product along with the Drione and they did the trick! I think my landlord is amazed but he won't let on. He's been paying an exterminator to visit twice a month. This stuff works, the exterminator is a waste of his money. It's been three weeks and I'm more than happy to say that I can rest peacefully.

Most effective in preventing the insects from maturing and multiplying. I mix it with the other pesticide I am using.

First time user
By Donna on December 17, 2010
I can not fairly rate this product at this time because this product prevents the adult roaches from populating and shortens life cycle it is a long term solution, but when you need immediate action you will need another treatment and I believe that this company provides those other treatments. I will purchase this product again and recommended to others that are seeking long term solutions. Thank you!
Must have for eliminating insect pests!
By A on April 24, 2013
I had a rather nasty infestation of German cockroaches in a rental property, and Gentrol, along with Demon-WP, Exponent to help the Demon-WP against resistant roaches, and Phantom to give long term protection against reinfestation, and that was the END of the roach problems inside of two weeks.

black worms in my NEW shower!
By D.b.s. on March 19, 2013
We had a new extension put on our house a year ago. We added a bathroom on the second floor. One day when I was cleaning the shower, I noticed these black small worms coming out of the grout. There were hundreds washing out when I squirted water along the edge. I tried everything I could think of. I finally found this website and bought the hotspot, it eats up organic matter that the drain fly larvae feed on. It also drew them out of their hiding space and I was able to kill them. I would still see a few, so I called up "domyownpestcontrol" and they suggested buying the Gentrol IGR Concentrate. This doesn't allow the larvae to mature into a fly, and thus cannot reproduce. I bought a squirt bottle in Target and diluted the Gentrol with water. I did this treatment a total of 3 times. (You have to wait 10-14 days for each application). Yay!! Finally I am drain worm free!! I can't believe I finally conquered these things. They are so hard to get rid of. They weren't coming from my drain, they were in the tiniest crack in the grout in the shower floor. I am so happy I found this product and the customer service representatives were so helpful and nice. Thank you!!!
By Bill on February 10, 2013
This product just palin works on german roaches. It is not an overnight cure, it takes sometime and multiple applications. Used with a good pesticide does wonders. You will need more than a single bottle grab the 10 pack, you wont be sorry.
gentrol IGR Concentrate
By Eluv on February 6, 2013
I mixed it with a temprid insecticide and haven't seen bugs in over 2 weeks, from previous experience and from advice from a friend that is a professional exterminator IGRs work best if mixed with a good insecticide rather than if just used alone so do yourself a favor and pick up a good one along with a sprayer all three of which I bought from this website and so far so good...I plan to re spray in 2 weeks to follow up
By John on February 4, 2013
I received my order in just a couple. The item was exactly what I was looking for. Thank you very much.

Been trying to kill roaches forever with Demon-WP. I finally spoke to DMOPC and they said that I also needed a growth control as well. I had a major infestation in an apartment that was spreading to other apartments. 1st Spray took out 90% about 10 days ago and just sprayed yesterday and plan one more spray in another 10 days, I will also mention that I have been sealing up every crack and crevice I can find, and using the bait stations and phenom traps as well. Things are getting much better. Even though the product says it works for 3 months I am still using it right now to get rid of all of the creatures since I am seeing some baby's being born still. It does have a pretty strong odor to it.
Works well on German Cockroaches
By Charlie on December 16, 2012
This was for my son's townhouse that was overrun by German cockroaches. I made my own kit by purchasing Gentrol IGR Concentrate, Maxforce FC Magnum and Demon WP Insecticide. They used these products and said they noticed a huge difference by the next day. They are going to apply two more times at two week intervals. I think that may wipe them out completely. I highly recommend these products.

Gentrol IGR Sterilant
By Steve on October 29, 2012
We have used this for roaches, bed bugs, pantry insects (Indian meal moth, etc.) and carpet beetles. This has always been a part of our solutions. Really helps with very and chemical resistant insect populations.

March 14, 2010 Patrick asked:
QCan Gentrol IGR concentrate be used as a mix (diluted) with other insecticides?
Can Gentrol IGR concentrate be used as a mix (diluted) with other insecticides, say 1 gallon of Suspend SC or Demon WP and how much Gentrol IGR to dilute to it?
AYes, Gentrol IGR concentrate can either be applied by itself in a gallon of water, or you can mix it directly with any other insecticide you happen to be spraying with. The Gentrol IGR comes in 1 ounce vials, which is the exact amount you need to mix with each gallon of water or gallon of other insecticide. 1 ounce or 1 vial of Gentrol IGR per gallon of water.
August 8, 2010 Anna asked:
QCan you mix Gentrol IGR Concentrate with Phantom Insecticide?
AYes. Gentrol can be mixed with most insecticides with no problem.
October 19, 2010 George asked:
QIf bed bugs walk over dried Gentrol IGR, does it work? Or does it have to be sprayed on a live bedbug?
Does it work with all roaches? If yes, which ones?
AGentrol IGR does not have to be applied directly to bed bugs or roaches to work. It has a residual that can last up to 4 months, so it can be picked up by bed bugs, roaches, drain flies and pantry pests long after it dries. It will work on all species of roaches.
August 8, 2010 Anna asked:
QCan you mix Gentrol IGR Concentrate with Temprid SC?
AYes. Gentrol can be mixed with most insecticides with no problem.
January 28, 2010 Ronda asked:
QAfter spraying for Bed bugs, when can I re-enter the room?
ATypically it takes about 30 minutes for the bed bug spray to dry. Once it is dry it is perfectly fine to re-enter the room again. Most people will wait 1 hour just to be safe.
December 4, 2012
Quinn from Chelmsford Ma asked:
QIs it safe to be around Gentrol IGR if I am pregnant?
AThere are no special precautions to take for pregnant women when using Gentrol IGR. We do recommend that you let someone else apply any insecticide or IGR and wait for the products to dry before you go back into the treated areas.

Joel from Sunnyside,ny asked:
Qcan I spray gentrol on all the walls and ceilings in my apartment?
I have small kids and am worried once the Gentrol dries if the residual is bad for them if they touch the walls? Also I have pets, what happens if I spray the floors, will the residual affect my dogs?
AYou should apply the Gentrol IGR as directed on the product label, directly into cracks and crevices around door frames, window frames, baseboards and under appliances. There is no need to spray the entire wall, ceiling or floor. All children should be out of the area during the application and they can safely return to the treated as soon as it has dried. The dried residual will not have any effect on people or pets even if they touch it. Also, by applying the product directly to cracks, crevices, voids and other inaccessible areas you will be limiting anyone's exposure to the product.

James from Salt Lake Utah asked:
QHow does this product work when coming in contact with the insect?
I'm trying to figure how it works. For example if I spray and then a bug walks across the place where I sprayed once it's dried how does that effect and come in contact with the bug is it just through its feet? Also how long will the product stay there for?
AIt does depend on the type of insect but in general the dried residual of Gentrol IGR will last for 14-120 days. Be sure to read the product label to see how often you should retreat for the pest you are targeting.
July 29, 2012
Wayne from Perry, Ga asked:
QHow do you apply for drain flys when you are unsure which drain they are coming from?
AWe recommend you use the Gentrol Aerosol for drain fly infestations. For drains, apply product into and around the downspout and catch basin area. Coat these areas thoroughly as fly larva develop in the scum buildup on the sides of drain pipes. Repeat applications at 2 to 4 week intervals depending upon the severity of infestation. You can treat all of the drains in the infested areas.
June 24, 2012
Jenny from Normal, Il asked:
QIf you are spraying Gentrol IGR, what do you do with your cat?
Can a feline become ill due to exposure to this chemical?
AYour cat should be removed from the room where you are applying Gentrol IGR (or any other pesticide) and should not be allowed back into the room until the application has dried. While most cats will not become ill if exposed to Gentrol, some cats are more sensitive to chemicals than others which is why all pesticide product label instructions indicate removal of animals prior to the application. Be sure to read the Gentrol IGR product label for complete usage instructions.

Emerson from Nyc asked:
QCan I use this with Riptide and the ulv fogger??
AGentrol IGR is labeled for use in a fogger and can be mixed with most other insecticides including Riptide. Please refer to the Gentrol product label for complete usage instructions.
October 31, 2011
Daniel from Payson, Utah asked:
QIs there a generic brand similar to Gentrol?
Gentrol is so expensive. Is there anything else that has the same active ingredient that would work as well that is cheaper?
AThere is no generic equivalent of Gentrol IGR. We do have other insect growth regulators that are a little less expensive that may work for the insects you are trying to control. You can see our full line of IGRs by following this link: Insect Growth Regulators. You should click on the product label link on each product page to make sure the IGR will fit your needs.

Javier from Van Nuys California asked:
Qen cuanto tiempo muere la bedbug despues de caminar por el area tratada con gentrol igr
o cual veneno es el mas efectivo para que se muera rapido despues de pisar el area tratada estando ya seca el area
A Gentrol IGR no es un insecticida y no va a matar a las chinches. Gentrol IGR es un regulador del crecimiento de insectos que sólo va a alterar los patrones de crecimiento del insecto y detener las chinches de alcanzar la madurez sexual. Cuando se utiliza Gentrol IGR en un programa de control de bedbugs (chinches de cama) se debe utilizar junto a un insecticida que tiene la etiqueta de bedbugs, como Temprid SC, Phantom o Equil Lambda 9.7. Cualquiera de estos tres productos mataran los insectos dentro de 24-72 horas después de caminar por el área tratado (mojado o seco). La única manera de matar a estos insectos más rápido es para rociar directamente con un producto como Bedlam o Sterifab.

July 21, 2011 Sue asked:
QCan I use MotherEarth D or Drione Dust after Gentrol IGR Concentrate?
If I can do it, how long do I wait for apply dust after I use Gentrol IGR Concentrate?
AYou can use either dust product after using Gentrol IGR. You only need to wait until the Gentrol IGR is dry before you can apply the dust insecticide.
January 24, 2011 Cuddy asked:
QWhen using Gentrol, how long can you leave it in the sprayer before you dispose of it?
AAfter you dilute Gentrol with water, it should be used within 24 hours. Also, you should not store pesticides in your sprayer as they will break down the rubber hose, seals and gaskets and could even cause damage to to the tank over time. Only mix what you can use at one time.
