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. 1oz. bottle. Gentrol Concentrate should never be used to eliminate a roach population by itself. Gentrol will not kill roaches...it only prevents them from reproducing. You should use roach baits and roach sprays in conjunction with the 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.
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)
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:
Food Handling Establishments
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.
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.
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.
Gentrol IGR Concentrate is not intended for outdoor use because it is not photostable (the product breaks down quickly in direct sunlight).

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.

By J. on May 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.

Gentrol IGR Concentrate
By Donna on July 19, 2010
Most effective in preventing the insects from maturing and multiplying. I mix it with the other pesticide I am using.
gentrol IGR concentrate
By Daniel on March 4, 2014
The main reason I purchased this product was to use it along with other chemicals when I'm killing bedbugs. The major pest control company I work for won't give it to me for my use, and as it has a growth inhibitor in it which is important if you miss any eggs when you are treating and steaming the inhibitor won't let the nymphs shed their skin to get to the next stage. Thus you eliminate them a lot faster. I bought it with my money to better serve my customers. It works and is well worth the price.
By Richard on January 16, 2014
After using only insecticide and not seeing any real results of less roaches I began using Gentrol mixed with Demon and occasionally sprayed Gentrol alone in certain cracks and crevices around home. Started in April-May 5-6 roaches a week, by June minimal roaches - saw 2-3 a week, by August no roaches. Will continue treatment this spring and into summer to check consistency.
Did the job for our roach problem
By Gabriel on December 18, 2013
Used with Cy-Kick CS and had amazing results. We had multiple breeds of cockroaches living throughout our house and this combination did the trick. We did a crack/crevice application to get under molding and back behind and in-between cabinets and then used a regular spray application to get the normal areas of the house.

Works with roaches
By Ace on October 31, 2013
This product was mixed with another chemical & works well. It's takes sometime to get results so don't expect immediate results, but they will come in time.

It appears to be working as the roaches I am seeing are less and mostly very small. The larger ones are deformed. Still coming out in the daylight and at night. Will see but I think they are getting less in numbers.

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!!!

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

March 14, 2010 Patrick asked:
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.
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.

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.
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.

Esteban from Harlingen, Tx asked:
QCan I spray Gentrol IGR concentrate anywhere i normally spray my insecticide? If so does the IGR have any residual on surfaces?
January 20, 2014
Corey from Florida asked:
QCan Gentrol be sprayed in the same place Maxforce gel baits are set? Or should I spray in different locations?
A Gentrol IGR is not recommended to applied directly to the areas where the roach bait gel is present. Please keep in mind that Gentrol spreads out from its point of application. This means that the roach does not have to come in direct contact for the Gentrol to break down the reproductive cycle.
December 16, 2013
Paul from North Bergen, Nj asked:
QIs wearing a proper mask with filters necessary when spraying Gentrol?
This is how I was trained. However, I read the label and instructions and I never came across wearing a mask.
A While going above and beyond with safety is always encouraged, the product label itself states all safety instructions that need to be followed. If there is ever a doubt, go with the label as it is what is considered law for its minimal safety equipment required.

Lori from West Palm Beach, Fl. asked:
Is Gentrol ok to use for fleas along with demon wp in a pump sprayer? I have a serious outbreak and have literally tried everything but the little babies keep popping up. My dog is on Frontline Plus and Comfortis with an Adams flea collar and still we have the little buggers. HELP!
Gentrol IGR is not actually labeled to treat for fleas and Demon WP is not labeled to be used in the areas indoors that you would need to treat to eliminate fleas. Demon WP is only labeled for spraying on cracks and crevices and baseboard areas so it would not be appropriate or flea control indoors. We would recommend our Indoor Flea Kit which provides you with the necessary components to completely eliminating fleas in your home the most efficient way. We also have a video on that page that and in our "Learn Videos" tab that shows you step by step how to use the products.

Mike from Delmar Delaware asked:
QDoes Gentrol have the same effects on silverfish it has on cockroaches as far as feeding habits?
November 7, 2013
Michael from Wichita, Ks asked:
QIs Gentrol a good combatant for fruit flies?
If it doesn't work well, what is a good chemical to use for knock down and long term residual? Besides a trap/cup.
A Gentrol is a product used to sterilize fruit flies. This means it will keep them from reproducing, it is not a product that will kill adult fruit flies. For knockdown of the adult fruit flies, you should use 565 Plus Aerosol or Clean Air Purge.

Courtney from Syracuse, Ny asked:
QWhat is the shelf life of GENTROL IGR concentrate after being mixed with water
A With any of our concentrates, you want to make sure you use the mixed solution within 24 hours of mixing.

Robert from Salt Lake Ut asked:
QCan an IGR like Gentrol concentrate be mixed with this product?
A We apologize but you did not state what product you are wanting the Gentrol IGR to be mixed with so we can not say for 100% sure that there are no problems with this. However, Gentrol IGR is designed to be mixed with most insecticides that are labeled for the same insects and treatment areas as its label. Please let us know if you have any questions.

Dan from Richland, Wa asked:
QCan Gentrol and Transport Mikron be mixed?
Yes, you can mix Gentrol and Transport Mikron together. You want to mix 1.25 oz Transport Mikron with 1fl oz Gentrol into one gallon water.
August 8, 2013
QIf you recommend mixing Gentrol IGR, why is it not included in the bed bug kit?
A The Gentrol IGR is the only birth control that has been shown to work on bed bugs, however it is not 100% guaranteed to work every single time in every home. With that lack of 100% we dont want to make you pay for it and give it to you as an option to purchase increase your effectiveness of control. Please let us know if you have any other questions.
