Gentrol Concentrate IGR Insect Growth RegulatorBy E. Spears on 2/8/2012I 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.
Gentrol Concentrate IGR Insect Growth RegulatorBy K K on 7/10/2011This 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
