    Used Temprid FX & Gentrol for roaches,ants and spiders. Amazing job done!! Gentrol did away with all of them or so it seems. I'll always use these 2 products they work extremely well. Thank you.

    Good Stuff

    By Brian on 02/15/2019

    Amber recommended this for the apartment building. We had a few problem tenants which spread the issue to other units. We hit all the units and now the roach issue went from very serious to pretty much under control in less than 90 days.

    When mixed with the Bug killer 1 oz bottles. Kills them dead and keeps Them from coming back. Have repeat orders on this product.

    Bed bugs

    By Douglas on 01/09/2022

    Applied according to instructions. Waited 18 days and reapplied. Still have very small bed bugs along with large full size bugs. The application was done according to instructions. The first night after application we found eight very small bugs and five large bugs. This product seems to not have slowed the hatching of new bugs as advertised. Would not recommend this product, save your money and hire a professional. Save the headache of doing it yourself. Product is not what is advertised.

    DOES NOT WORK ON BED BUGS

    By Rob on 11/23/2022

    A recent (2021) study in Pest Control Technology magazine, "Shedding Light on IGRs and Bed Bugs", shows NO effectiveness on ANY stage of bed bug development. We had to remove it out of our formulation for all of our bed bug work.

    Expert Response  Expert response:
    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. It is not something we recommend or state is required to get control for this reason.

    IGR is a MUST to knock down fleas !

    By Phil on 12/16/2023

    I was a Pest Control Tech. way back when and found my self with a flea problem. I tried different "off the shelf" products to no avail. Adding 1oz of Gentrol IGR to 1 Gal. of Tempo SC Ultra did the trick in one application. IGR is essential to stop the life cycle of most pests, especially fleas. Nice to have the education of my former profession ! Thanx DO MY OWN ! P.S. READ THE LABEL !

    Used for years

    By Karen on 11/29/2024

    Had a severe roach about 3-4 years ago. Started using Gentrol along with an insecticide, within around 3 months roaches were just about gone. I'm still using the product and have kept sightings down to hardly none.
