    Gentrol IGR Concentrate

    By Brenda on 08/21/2015

    This product is very good, it works. Make sure you follow the manufacturer instructions. I will definitely 're-order the Gentrol IGR Concentrate. I'm very pleaded with the results. It's best to layer when using the product. After the first application, wait about 2-3 weeks before you spray again and spray in the same spots and different spots if You are still seeing bugs(roaches) you should be seeing less by now.

    Awesome that we can rise above the exterminator union.

    By Bill on 08/01/2016

    DO MY OWN Pest control has been a hero to us all... we need this service it will save you time and trouble as well as money. Use lots of Boric and Acedic acids and of course a lofe-cycle breaker like this one will guarantee the bed bugs will stAy away. Also the ground glass or DE is very useful especially with added bait (cow or human blood probably). Good luck you will be much happier than paying the Cartels to come and "check you out" and you will succeed in your endeavor to rid yourself of pests. Also look up "Fly Parasites" too while you are at it.

    Product Review

    By Alayna on 03/13/2017

    I used this for a minor bed bug infestation. I also ordered Bedlam and Sterifab. Seemed to work fine. However, my cat got fleas while treating for bed bugs, so this was like, another issue! Just bought over the counter for the fleas and some frontline. Do your research; these two insects are very similar but not the same, for anyone suffering from bites!

    Didn't work for me

    By Tommy on 06/02/2017

    I used as directed, and treated my house and furniture twice, and it had no effect at all, bedbugs are still everywhere, the second time I even treated the carpet, I did every wall, every room, even the bathroom. I really had my hopes up, I been using this since February and here it is June, Im gonna keep trying, might as well, I'm stuck with it and out $75.

    Thank you for your review. We are sorry to hear that Gentrol IGR is not working for you. However, Gentrol is not meant to kill bed bugs so you would not notice a reduction in adult bed bugs. Gentrol is a growth regulator so only nymph stages and eggs would be impacted by the application. Please take a few moments to read our bedbug guide to learn how to implement a successful bedbug elimination program: http://www.domyownpestcontrol.com/how-to-get-rid-of-bed-bugs-a-449.html

    Gentrol

    By Jenny on 07/10/2017

    Having advion and Gentrol is the best way I've found to finally conquer those peaty bugs and other spiders ants as well . The advion is sooo much better than combat just no comparison . It takes a few days but after a week I knew I had it going on

    Eehh

    By Brian on 07/20/2018

    It's been about 3 weeks since i sprayed initially. Plus i spot treated once a week after. The roaches do seem to be a bit deformed looking...but i do still see some tiny ones so maybe i didn't spray enough or maybe another treatment will be needed. 3 stars until then

    I think this stuff works

    By Amanda on 08/24/2018

    I use this stuff with Advion bait. It apparently makes roaches sterile. It doesn't kill them so you need some kind of bait to go with it. I mix a half a bottle into a half gallon of water and spray everywhere roaches walk. Walls, behind appliances etc. I've even mixed it with a little sugar on a plate. Baby roaches love it. I have been seeing way less pregnant roaches than usual.

    Very Effective

    By G on 12/26/2018

    I have used this product on numerous occasions and it works like a charm. It has been used in conjunction with Demon WP, Temprid SC and FX. You will notice the difference in the look of the German cockroach population shortly after application. They seem to have a translucent color.

    growth regulator

    By Mike on 11/13/2020

    I have used this product for the past two years in conjunctions with Temprid FX. It does not react with the pesticide and gives you an excellent one two punch when dealing with bed bugs. I love that it provides up to 4 months of protection, this is four month of bed bug lifecycle interruption! This is a great little tool to add to your bed bug fighting toolbox.

    Gentrol for roaches

    By Rogeina on 03/05/2021

    I used this along with Temprid. I've seen an immediate decrease. The few I have seen since either are dead, dying or deformed. I would recommend using Gentrol along with any product you choose to use.

    Great Stuff, Best Price

    By Janice on 06/03/2023

    Use for those gross outdoor American roaches. Gentrol along with Demon WP is a game changer. Overrun with these pests a couple of years ago I would not go outside and enjoy the beautiful Spring and Summer nights and mornings. After routine monthly applications starting in April through October at first, the decline in population is amazing. Now, using this combo twice a year in Spring and early Fall for prevention. Great for spiders, including Black Widows, too.

    I used this in combination with Demon WP. It's been about three weeks since I applied. I'm seeing weird roaches now, I think it's caused deformities.

    Gentrol Bed Bugs

    By Tim on 09/19/2012

    A very good product as it does start the process of eliminating these pest. I had researched the different types of chemicals for these bugs and found GENTROL to be the answer. Dump one bottle in a typical pump garden sprayer and add a gallon of water, I use a old gallon milk jug and bingo, start spraying your headboards and all wood products and soak the area between the base boards and carpet. You may still after a while still see a few but this stops them from pro creating. Maybe I can use this on my 13 yr old daughter?... just kidding... Delivery was very fast and a great place to do business with.
