Gentrol IGR Concentrate

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.

Gentrol Concentrate should never be used to eliminate a roach population by itself.

* Gentrol will not kill roaches...it only prevents them from reproducing.

* Use roach baits and roach sprays in conjunction with Gentrol Concentrate.




How Gentrol IGR Concentrate Works

Gentrol IGR (Insect Growth Regulator) 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. Cockroaches and bedbugs exposed to Gentrol will become adults incapable of reproducing.

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. Gentrol Concentrate should always be diluted with water when applying with a sprayer. Because Gentrol is an insect growth regulator and not an adulticide, it should not be used as the sole protection for target pests.

Target Pests

Roaches, drain flies, fruit flies, bed bugs, stored product pests

PESTS CONTROLLED WITH GENTROL IGR CONCENTRATE: Cockroaches, drain flies, fruit flies, bed bugs, stored product pests (including Indian meal moths, rice moths, tobacco moths, red flour beetles, confused flour beetles, lesser grain borers, merchant grain beetles, sawtooth grain beetles, warehouse beetles, cigarette beetles, and Dermestid beetles)

Target Uses

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. Because of its broad labeling, Gentrol can be used in many sensitive areas where other sprays cannot. Gentrol is an excellent accompaniment to baiting programs for cockroaches, and it can be tank mixed with insecticides for treating bed bugs, roaches, or other listed pests.

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:

  • Warehouses
  • Food Handling Establishments
  • Schools
  • Hospitals
  • Nursing Homes
  • Aircraft, Ships, Trains, Trucks

ACTIVE INGREDIENT: S-Hydroprene 9.0%

Gentrol IGR Concentrate Application Instructions

Use Gentrol as a general surface spray, fogging, spot, or crack and crevice application. Mix Gentrol Concentrate with diluent and apply with spray or hand application equipment, such hand-pressurized or power-operated sprayers capable of delivering general surface spray, fogging (space spray/mist), spot, crack and crevice spray applications, or with a paint brush, roller, or similar device.

Mix GENTROL IGR Concentrate with water and apply with spray or hand application equipment, such as hand pressurized or power-operated sprayers capable of delivering spot or crack and crevice spray applications.

Dilution Preparation:
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.

Gentrol Concentrate may be tank mixed with an adulticide currently registered for use, unless the product label prohibits such use.

Gentrol Concentrate may also be converted to a foam. For best results, use the higher amount of the foaming agent rate range.

Always read the product label completely before use.

Each 1 oz. bottle yields 1 gallon of finished solution. Each 16 oz. bottle yields 16 gallons of finished solution. 1 gallon of finished solution covers 1,500 square feet of surface area.

Standard Application Dilution rates / Mixing Ratios for Gentrol IGR Concentrate

  • 1 fl. oz. (30 mL)/gal. of water – surface, spot, or crack and crevice applications
  • 1 fl. oz. (30 mL) per 12,000 cubic feet – fogging applications

Gentrol IGR Concentrate is for use in the following areas:

Apartment buildings, bakeries, bottling facilities, breweries, boiler rooms, cafeterias, candy plants, grocery stores, day care centers, hospitals, residential homes, hotel/motels, office buildings, kitchens, laboratories, cereal processing facilities, manufacturing plants, mausoleums, meat and produce canneries, nursing homes, restaurants, schools, locker rooms, stores, taverns, warehouses, as well as various modes of transportation such as aircraft, buses, trucks, trailers, rail cars, and marine vessels; food and non-food areas of food-handling establishments.

Indoors

Fogging Application: Apply Gentrol Concentrate as a fog or an ultra-low volume (ULV) mist with equipment such as ULV, mechanical misting sprayers, aerosol generators, or thermal foggers to achieve uniform coverage. Apply at a rate of 1 ounce Gentrol per 12,000 cubic feet. Use water or oil as diluent, depending on the type of equipment used. Fogging applications are best for larger facilities including warehouses. Close room or warehouse and shut off all ventilation systems. Apply the product in the air and direct mist toward all areas that may harbor target pests. After treatment, leave the room closed for 30 minutes or longer as recommended by the equipment manufacturer or the labels of other products applied in tank mixing. Do not remain in treated area; ventilate before reentry.

Bed Bugs: 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. Retreat at 14 days for heavy infestations. Gentrol cannot be used as the sole treatment for bed bugs.

Drain Flies, Fruit Flies: Apply Gentrol to areas of fly breeding. For drains, apply product into and around the downspout and catch basin area. Coat these areas thoroughly as fly larvae 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.

Pantry/Cabinets, Small Food Storage Areas: Apply as a surface spray, crack and crevice spray, or spot treatment to pantry and cupboard shelves or other areas where food is stored. Prior to spraying, remove all food containers and foodstuffs. Do not replace food containers or foodstuffs until spray has dried. Do not store food in open containers in treated pantries. Destroy any infested food packages to ensure proper control.

Outdoors

Gentrol IGR Concentrate is not intended for outdoor use because it is not photostable (the product breaks down quickly in direct sunlight).

    4 of 5 stars  This product works! Thank Goodness!
    By Eve in Cocoa Florida on 05/16/2010
    Verified Purchase

    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!

    5 of 5 stars  It's just works!
    By Kahina in Brooklyn,Ny on 10/22/2010

    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.

    5 of 5 stars  The Best.
    By Chris in New York City on 07/04/2010

    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.

    5 of 5 stars  This works!
    By J. in New York, New York & Oklahoma on 05/22/2011

    A few years back our Queens, NY apartment became infested with bed bugs. The landlord called an exterminator, who treated our apartment about four times. One of the exterminators (then sent a different one each time) told me that the bug spray mix wasn't really meant to get rid of bed bugs permanently, just put them into temporary hiding. After the four or so treatments, we still had the bedbugs. I decided on this product after reading the literature that was available then. It turned out to work. After one treatment of this, the bed bugs slowed down, and after two they disappeared. I think I did this for a total of three times, and we never saw the bugs again. I had purchased the whole box and had most of it left after treating my apartment three times. Needless to say, the entire box of the Gentrol IGR cost less than a single visit from a NYC exterminator. As an added benefit, Gentrol IGR also fubars roaches. I now use it on my own commercial property for roach control, and for me, it is more effective (by killing the bugs and by cost) than hiring the bug company.

    5 of 5 stars  Gentrol IGR Genetic Warfare for Roaches :)
    By Tim in Clute, TX on 05/02/2012
    Verified Purchase

    I sprayed this down by itself a few days before performing my German Roach Normandy beach mission and I felt like I was on a secret mission to disrupt the worldwide roach population. This Gentrol with MaxForce FC Magnum bait and some Demon WP completely decimated a 20 year German roach problem in South Texas. All three totally killed every bug in the house, haven't seen or heard a peep for over two weeks and for the first time ever, I can say that they are gone with absolute certainty. Still got a spray bottle left in reserve just in case they ever try a counterattack. Thanks for an amazing product and very fast shipping.

    By Bill in San Diego, CA on 08/01/2016

    DO MY OWN Pest control has been a hero to us all... we need this service it will save you time and trouble as well as money. Use lots of Boric and Acedic acids and of course a lofe-cycle breaker like this one will guarantee the bed bugs will stAy away. Also the ground glass or DE is very useful especially with added bait (cow or human blood probably). Good luck you will be much happier than paying the Cartels to come and "check you out" and you will succeed in your endeavor to rid yourself of pests. Also look up "Fly Parasites" too while you are at it.

QCan Gentrol IGR concentrate be diluted with other insecticides?

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.

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.

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.

QDoes Gentrol IGR Concentrate kill spiders?

A

Gentrol IGR Concentrate is an insect growth regulator.  It is not an insecticide and does not kill insects or spiders.  This product prohibits insects from being able to reproduce, but is not labeled for spiders.  We recommend using Onslaught FastCap for spider control.

QCan I use Gentrol IGR in the Fog RX Propane Fogger?
What do I need to use to make Gentrol work with this fogger and make the fog? Can I mix Gentrol with water and put it on the little tank of the Fog RX Propane? Would it work?

A

Per the product label for fogging Gentrol IGR:  Fogging applications are best for larger facilities including warehouses (Refer to Warehouses section below).  It would not be recommended to use Gentrol in the Fog RX Propane Fogger as it is more suited for small up-close fogging applications.  If you wish to treat a home using Gentrol IGR it would be better to use a standard pump sprayer and mix with water.

QCan Gentrol be mixed with a contact spray like Sterifab or JT Eaton Kills Bed Bugs?

A

No. Steri-Fab is an alcohol-based product, and both the Sterifab and the JT Eaton Kills Bed Bugs come as an end-use product (which means that it does not need to diluted with water). Gentrol must be diluted with a gallon of water to be properly applied. We suggest using an insecticide like the Temprid SC with Gentrol IGR.

QIs Gentrol IGR safe to use around exotic birds?
Birdfood is put in freezer when it arrives. We've got Indian Meal Moths.

A

QWhat would happen if a kid licked some of the liquid of Gentrol IGR?

A

Children should be out of the area during treatment until dry when using Gentrol IGR.  When used as directed children should not come into contact with a treated surface while it is wet and the product is only meant to work with insects. The MSDS has further information on safety and does not list any toxicity issues. You can also check directly with your doctor or the manufacturer if this has happened and there are concerns. Zoecon can be reached at 800-877-6374.

QCan Gentrol be used for roaches, bed bugs "alone" without a main pesticide?

A

Gentrol IGR will not kill bedbugs or roaches. While you can use it alone we do not recommend you doing so. The bedbugs and roaches that are already mature at the time of the application will continue to mate and reproduce as the growth regulator will not stop this process. The IGR will only stop immature insects from reach sexual maturity and it is not 100% effective on any given generation. Using a growth regulator in conjucntion with an insecticde and a comprehensive elimination program would be recommended. You can learn more about roach and bedbug control by reading our Roach Treatment Guide and our Bedbug Treament Guide

I have an infestation of Indian meal moths on my storage of dry nuts in the shell (walnut, hazelnut, almond, pecans, peanuts), Can I spray around the nuts storage bins and within the nuts shells or just outside the storage bins?

A

Gentrol IGR cannot be used on anything edible or on any stored food product.  You would direct treatment to cracks and crevices around the storage bins only.
