Find this in our 100% Guaranteed Bed Bug Kit

Target Pests

Gentrol is used to control bed bugs roaches fleas flies and many other labelled insects.

For Use In

Gentrol IGR can be used in food areas of food handling establishments. May also be used in residential commercial warehouses and other areas bedbugs or roaches may harbor.


To apply Gentrol as a diluted spray solution you will need a pump sprayer or other form of compressed air sprayer.

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, around water pipes, doors, windows, and behind and under appliances/equipment, furniture and beds.

To treat bedbugs with Gentrol, apply to harborage points mentioned above; in addition, under beds, bottom side of box springs, 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.

You will not see immediate results as Gentrol is an insect growth regulator that works as a chitin inhibitor. That means that affected insects reproductive organs will no longer work and they cannot reproduct. This is why we call it birth control for bugs but it also means that insect infestations with a long reproductive cycle will not be controlled immediately using only Gentrol.

Coverage Area

Each ounce of Gentrol IGR will treat up to 1500 square feet.

Time to Kill

Gentrol IGR is a slow acting insecticide. It can take up to 2 months for control to be noticeable. Mix with a contact insecticide when applying Gentrol for quick results.

Mix Rate

Gentrol is mixed at a rate of 1oz per gallon of water. It should be tank mixed with adulticide products as Gentrol alone will not provide quick results.

Active Ingredient

Hydroprene 9.0%

Gentrol IGR Insect Growth Regulator

Eliminate Insect Eggs With Gentrol Insect Growth Regulator


Gentrols is an insect growth regulator which uses Hydropropane, a synthetic juvenile hormone look-alike to disrupt the target pests normal growth pattern. The intent of Gentrol IGR is to inhibit the growth of juveniles that are exposed to the compound so they're unable to reproduce into adults.


Gentrol is a popular choice among professionals who are fighting cockroaches and bed bugs since both of those species can lay several eggs a day, controlling their populations can be a nightmare.


When combined with an adulticide, Gentrol helps stop the endless cycle of reproduction that makes an infestation so hard to beat. This combination can be the difference between success and failure in a pest control job.


Using Gentrol is easy. Just mix 1 fluid ounce into a 1 gallon sprayer, shake to agitate the mixture and then you’re ready to start spraying. Gentrol can be applied to walls, floors, ceiling, attics, basements and over crawl spaces. Once applied, Gentrol can be active for up to 4 months.


For heavy infestations it’s recommended to re-apply gentrol every 2 weeks or so.


Gentrol is available in the 1 oz size in a very simple to use single-use container. They're also available at a 10 pack for a bit more savings per ounce or for professionals doing long-term control they'll definitely want to size up to the Pint because this offers the best savings per ounce.

A shopper on Aug 6, 2018

The last product I brought I shared with my Grand-daugther say said her boyfriends mom had bedbugs and they had seen a few over at there house. She has 5 children so Me and grandpa went on the attack no more bedbugs for now, ITs so easy to get them don't let anyone tell you that you are dirty,are don't have nice things because I am clergy, have had hundreds of people at my home. however, it only takes one guess, coming to stay at your house and you can get bed bugs, because they won't tell you they have them you just better check your beds, linens,sofas, and pillows from now on because you can bring them home from Hotels too! However, Solutions gots the stuff to kill, kill kill them dead. thank you. Kathleen C Finkle, Jacksonville, IL

This Product Will Get Rid of Your Roach Problem!
I used this product to get rid of a huge roach infestation. Once I put the vials out in the kitchen and bathroom, I noticed that in a month I rarely saw any roaches and the ones I did see had crumpled wings. Within 2 months I didn't even see the deformed ones. I had tried everything to get rid of my roach problem and this is the only product that worked permanently. I call it birth control for roaches.
February 9, 2012
Wow amazing product
This in combination with Invict is all you need to get rid of German Roaches. I called multiple pest control companies claiming they will take care of the problem after 4 to 6 months and were going to charge me upwards of $250. After price searching every where for these two products I found Epestcontrol.com Every night I went in the kitchen and turned on the lights I would see at least 5-10 roaches (big ones and baby ones)Within 2 weeks of using these 2 products the roaches were gone!I purchased these products around april 1st/2nd. It is now July 11th 2011 and I have not seen one roach. I have only done one treatment with 4 gentrol discs and 2 tubes of invict. I am located in Florida
