Gentrol Aerosol IGR - 16 oz. can

Aerosol containting IGR (Insect growth regulator) that disrupts pest development, preventing current and future infestations. 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. 16 oz. can.

Can not be sold or shipped to New York.

How Gentrol Aerosol IGR Works

The IGR (Insect Growth Regulator) in Gentrol Aerosol provides preventative action, since it disrupts stored product pests' normal development. Hydroprene, the active ingredient, prevents stored product pest, drain fly, and fruit fly larvae from progressing to the pupal stage of development, so the larvae die before they become breeding adults - and future infestations. Bedbugs and roaches exposed to Gentrol Aerosol will become adults incapable of reproducing, thus ending the cycle of an infestation. Gentrol IGR also stimulates egg-bearing female roaches to leave the harborage area and feed.

Since Gentrol Aerosol IGR is not an adulticide, it should be used in conjunction with other pest control treatment methods.

Target Pests

Bed bugs, drain flies, fruit flies, cockroaches, stored product pests

PESTS CONTROLLED WITH GENTROL AEROSOL IGR: Roaches, 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), Drain Flies, Fruit Flies, Bedbugs

Target Uses

Use Gentrol Aerosol for spot, void, or crack and crevice treatment of target pests as a supplement to other pest control methods. The aerosol form of Gentrol is convenient for treating flies around drains and sinks in homes, roaches in hollow table legs and voids in commercial kitchens, and bed bugs in hotels or homes. Gentrol Aerosol IGR has a foaming action for voids and a crack and crevice straw for hard to reach spots. The ready-to-use formulation is also convenient for small applications. Gentrol Aerosol IGR should not be used as the sole treatment for any of the listed pests as it is not an insecticide, just an insect growth regulator.

Gentrol Aerosol is ideal for:

  • Retail Stores
  • Restaurants
  • Bakeries
  • Food Processing and Storage Facilities
  • Any Hard-to-Reach Area

ACTIVE INGREDIENT: Hydroprene 0.36%

Gentrol Aerosol IGR Application Instructions

Shake well before use. As a general surface spray or spot treatment, Gentrol Aerosol is applied with a sweeping motion over a surface. Its visible, dissipating foam virtually eliminates the chance of missing any areas. You'll receive the same superior coverage for crack-and-crevice applications with Gentrol Aerosol's extension tube, designed for simple, accurate application in hard-to-reach areas.

To apply as a general surface or spot application, hold can 10” to 12” away from surface to be treated. Use a sweeping motion over the surface to be treated for complete coverage. This product applies as a light foam that dissipates readily. An oily residue may be apparent in heavy applications. The visibility of the dissipating foam eliminates the possibility of missed areas. For crack and crevice applications, use the supplied extension tube and apply to wall voids, hollow table legs, tube iron, gondola frames, voids, and supports.

Apply once a month for continuous protection, or more often if conditions warrant.

*Always read the product label completely before use.

Each 16 oz. can covers approximately 1200 square feet.

Standard Application rates for Gentrol Aerosol IGR:

*16 oz. per 1200 square feet of surface area

Gentrol Aerosol IGR is for use in the following areas:

Including but not limited to: Apartment buildings, bakeries, bottling facilities, breweries, boiler rooms, cafeterias, candy plants, grocery stores, day care centers, hospitals, residential homes, hotels/motels, office buildings, kitchens, laboratories, cereal processing facilities, manufacturing plants, mausoleums, meat and produce canneries, nursing homes, restaurants, schools, locker rooms, stores, taverns, warehouses, pet stores, 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


FOR BEDBUG Treatments:
GENTROL AEROSOL contains GENTROL Insect Growth Regulator (IGR). The IGR disrupts the normal development of bedbugs. Bedbugs exposed to GENTROL AEROSOL will become adults incapable of reproducing, thus ending the cycle of an infestation. Use GENTROL AEROSOL in areas such as, but not limited to: apartment buildings, hospitals, residential homes, hotels/motels, nursing homes, and marine vessels.

Spot or Crack and Crevice Applications:
Apply GENTROL AEROSOL as a crack and crevice application using the supplied extension tube. Apply directly to areas such as: wall voids, pipe chases, crevices, and false ceilings. Apply spot treatments to areas such as: storage areas, closets, 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. Retreat at 14 days for heavy infestations.

For Control of Drain Flies and Fruit Flies: Apply GENTROL AEROSOL to areas of fly breeding. 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.

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. Dispose of any infested food packages or materials.


Gentrol IGR is not intended for outdoor use.

    5 of 5 stars  German Cockroaches Completely Gone
    By Conrad in Las Vegas, NV on 12/13/2010
    Verified Purchase

    I had a huge problem with German Cockroaches. I tried raid, sticky traps, and even resorted to baking soda. Nothing worked and they kept showing up in my kitchen sink. I finally searched online and came across the Gentrol Aerosol. I sprayed every crack known to man and within days they were gone. I started seeing a bunch of dead cockroaches and knew this product did the trick. Highly recommend against German Cockroaches.

    5 of 5 stars  Really worked
    By Jonathan on 08/04/2008

    We used Gentrol IGR aerosol to attack a really horrendous roach problem in our house. Nothing else had had the slightest effect on this infestation, including two different visits by professional exterminators. Gentrol really worked, though it took several weeks to collapse the population. The present order of concentrate is to take care of a few stragglers, and keep our protection up.

    5 of 5 stars  Gentrol for Drain flies
    By Lee in Muskogee, Ok on 06/10/2010
    Verified Purchase

    We had an infestation of drain flies after a busted pipe was repaired under our kitchen slab. The plumbing company sprayed our drains and cleaned them by flushing them with hot water. They charged us $165. However, three weeks later, we still had them in the hundreds. I ordered Gentrol from DoMyOwnPestControl, and am very happy with the results. We are only seeing one or two on occasion and with another application or two we should be rid of them entirely. This company has excellent products and service. The shipping was fast and the product well packaged. Love the free shipping. I will definitely purchase from them again.

    5 of 5 stars  Phorid Flies
    By Randy in Rockport, TX on 09/23/2010

    This product works. I've been trying to determine the source of our phorid fly infestation for almost a year. We do not have any plumbing leaks. We fogged the house and used the sticky bug lights which kept the problem under control but never eliminated the flies. After treating all the obvious sources of infestation with drain foams, I finally realized I may never find every potential breeding location. I sprayed all the baseboards, cracks and crevices over my entire house with this product and within two days I noticed a significant decline. Within a week, we only have two new flies on the bug lights. I will be treating again in another week as directed on the instructions. In summary, I believe our year long nightmare is finally coming to an end.

    5 of 5 stars  Zaps roaches better than professional services!
    By Beachy in Fort Smith, AR on 07/01/2011
    Verified Purchase

    We own several rental properties and the worst thing is to have roaches take over a place. After spending lots of money on professional pest services we took things into our own hands several years ago, and started using Gentrol with whatever bait sounded best and the glue traps to pick up the stragglers. Have been able to totally eradicate roach infestations 100% of the time. Rarely requires retreatment.

All people and pets should be removed from the treatment area prior to the application of Gentrol aerosol, and they may return when the application is dry.

QHow does Gentrol Aerosol IGR differ from BedLam? Should I use both at once?
Is this product sold in stores? If so, which? If not, why?

AGentrol IGR is an insect growth regulator which means it does not kill any bed bugs at all, or any pest for that matter.  An IGR disrupts the insects reproduction cycle and prevents it from maturing and reproducing thereby slowing down the life cycle and allowing you to kill an infestation quicker because they are not laying new eggs while you are treating the problem.  Bedlam is strictly an insecticide and does the killing.  You can spray them both in the same places at once and they will not harm each other or react with each other.  They both do different things.  None of our products are found in stores because we sell only professional products that are not sold over the counter.  We sell the same products the professional companies use.

QWhich would you recommend more for fruit flies and drain flies, 565 PLUS XLO or Gentrol Aerosol IGR?
Also, can I spray directly into a drain with DF 5000 drain gel?

AGentrol Aerosol and 565 Plus XLO are two completely different products that are not comparable. Gentrol Aerosol is an insect growth regulator that helps break the breeding cycle of listed insects, but it does not kill them. 565 Plus XLO is a pyrethrin product that offers a fast kill of listed insects but no residual control. These products are usually used together to help control an infestation of drain flies. You would use the DF5000 in the drain to help remove the organic matter that the drain flies breed and develop in. The Gentrol Aerosol should also be applied to the drain. The 565 Plus XLO should be used to help knockdown the active flying adults around the infested room.

QI bought Phantom Aerosol and Gentrol Aerosol to kill the colonies of drain flies and fruit flies.
I was told to spray one in the drains and the other in cracks on counters. Which one do I use for what?


You definitely want to spray the Gentrol Aerosol down the drains. This product will control the growth and reproduction of the flies - keeping them from multiplying.  The Phantom Aerosol is a crack and crevice treatment. This product will kill the flies that are flying out and about that land on a treated area.

You may also want to consider DF 5000. This product is a gel designed specifically for drain flies.  Pour 4 oz of the product down each infested drain each night for 7-14 days.

QIs the Gentrol Aerosol IGR safe to use for roaches in a car?
I recently bought a used car, and after a week, discovered roaches in the car. I thought is was a one time thing, but it turned out to be an infestation. The Pest Control companies I've called will not work on a car. I've noticed they come out from the crevice where the seat belt buckle is in the backseat. Also, I have a toddler, and I'm nervous about using poisons in such a small space that he rides in. Can you recommend a course of action?


While the Gentrol would be safe to use it is only an IGR (birth control) so while it will stop the reproductive cycle it wont actually kill the roaches in the car. A better option would be something like Pivot Ultra which has the IGR and insecticide in one and is safe to be used in the crevices of the car where the roaches are a problem. Just keep your child out of the car while you treat and for at least a couple of hours until it has dried completely.†

QDoes the Gentrol IGR attract German roaches?
We moved out of our heavily infested apartment two weeks ago due to management not keeping up with our dirty neighbors and following through on having a pest control service. We were extra careful moving, but apparently these suckers hitched on our wooden fish tank stand. I noticed them 4 days after the move and have been freaking out ever since. After a long bed bug process 2 years ago, I ordered Phantom aerosol and the Gentrol aerosol. I had 2 cans leftover, so I sprayed the cracks & crevices in my kitchen, as well as used dust in all the outlets. What I noticed is that about an hour after spraying, 5 big females were out on the walls by the one area I sprayed. Is this normal? I sprayed the entire kitchen area of cracks, etc, so I'm hoping this doesn't mean I'm helping them spread out.


Gentrol aerosol will not attract roaches and neither will Phantom aerosol. They are placed as residuals to cracks and crevices to impede their reproductive cycle and to eradicate those that come in contact with the treated surfaces. Dusting the voids in the apartment is a great idea. We would also suggest applying a professional roach bait gel (to the areas not treated with Gentrol/Phantom) such as Maxforce FC Magnum to attract them. They will consume and share the food through contact and food sharing. Please take a few moments to review our treatment article for more information on a successful eradication program on How to Get Rid of Roaches.

QCan I use the Gentrol IGR and Phantom Aerosol for German Roaches?
Hi I have applied phantom aerosol spray in cracks crevices and baseboards for German roach problem. Can I spray the gentrol in same areas? Should I keep the application low as I have used vendetta plus in kitchen areas up high in cabinets ? Will gentrol interfere with the nygaurd Igr in the vendetta plus? For bedrooms bathrooms etc will the gentrol make Ore roaxhes congregate in those areas? How often do I apply the gentrol aerosol ? How long before the roaches will decrease I have used the phantom for about two months and am seeing a resurgence of smaller size roaches please help


It can take several months to get rid of a large infestation. Infestations do not get large quickly and, unfortunately, they do not go away quickly, either.†Yes,†Gentrolcan be used in the very same cracks and crevices where you spray†Phantom†and†can be sprayed behind and under the refrigerator to control German Roaches. For roach control, you should repeat applications every 4 months.†These insecticides will just kill the roaches that come in contact with it, but as long as you are keeping the Vendetta Plus seperate from the†Phantom Aerosol†and the†Gentrol IGR†they†will not interfere with each other.

QDoes Gentrol Aerosol work for Pantry Bugs?
I have gotten rid of the nest, cleaned and sprayed Gentrol in every nook and crevice. I have not seen an adult in several days. Does this mean they are gone or do I need to do something additional. I do not want them to come back. Much appreciated.


The Gentrol Aerosol IGR can be used to treat Indian Meal Moths and†other moth species that are listed on the label.†This†treatment†will help stop the insects'†reproduction and stop the growth of immature†insects. Our Pantry Pest Kit would be an excellent addition to your sanitation and Gentrol applications since it contains an adulticide, CyKick Aerosol, and†traps that will catch several of the most common pantry pest species.
