    Best for german roaches

    By Sweetie on 03/31/2016

    Best treatment for german roaches along with boric acid powder for the crevasses. It doesnt take thousands of dollars the Exterminators want to charge to get rid of this annoying pest.

    Safe for kids, pets, grownups

    By Elizabeth on 03/14/2017

    My tenants have children & HAD bedbugs, which have been found infesting at least one DC school. As a grandmother, I don't feel comfortable letting the tenants "control" the problem with insecticides, & the probability of reinfestation via schoolbus or lockers make heat treatment of their 5-bedroom house too expensive. So we mix up a half-gallon of Gentrol each month & spray SAFELY!

    Gentrol Concentrate

    By Dovie on 05/23/2017

    I ordered 2 of these small bottles to try since my daughter said they ordered it and they only used it twice and got rid of roaches in a home they were buying. I wanted to get rid of the critters that came into our home from a house across the road that is being demolished...I am very pleased that it is working and doing the trick and we're still on the first bottle. So that definitely says it works and we are pleased. Thank You !!

    Something worked

    By Tammy on 10/18/2017

    Ok, I'm not one to do reviews....BUT....something worked!!! I live in the city and the neighbors got evicted AND WERE INFESTED WITH ROACHES!!! The landlord took the kitchen cabinets out of the house and slammed them on the ground and roaches went everywhere!!! Long story short, they got into my house!!!!!!!!!! I was freaking out!! My daughter is allergic to them! I honestly don't know what worked because I used temprid sc, fenvastar ecocap, boric acid, diatomaceous earth, delta dust, and gentrol....one or all of those worked!! It was not over night. It took about a month, but it did work.

    Gentrolize them Roaches

    By Marco on 01/05/2018

    I never had roaches for 7yrs and then I say them in my house. Tried all I could to get rid of them but nothing worked. Second time using this product and it is a real good thing in getting rid of those small brown roaches. Nothing seems to kill them but this product seems to slow the reproducing of them and with other cleaning methods they all die. Bought again as a precautionary measure in doing my own pest control and will keep buying it.

    Worked for roaches and bed bugs

    By Jeremiah on 10/20/2018

    I used this mixed with temprid fx for my roach and bed bug problem.( used boric acid and cimexa dust too) I would see a couple roaches a day usually when I got up in the morning for work. I sprayed once and seen a couple dead roaches right away and would only see a roach every couple days. My bed bug problem that I have had for roughly a year was pretty small so I seen only two bed bugs after the first spraying and they were pretty weak looking (they usually run away but not this time). A week after the first spraying I sprayed again. even in the walls where I drilled holes and in every crack and crevice I could find, even in the trim on the ceiling. After the second treatment i didn't see any roaches or bed bugs at all even with me waking up randomly in the middle of the night to check for them in the usual places. A week later I fogged my house with a thermal fogger useing shockwave just to make sure and didnt see a single roach or bed bug any where so im gueasing the temprid/gentrol took care of them on its own. Interesting thing i found though was even after all them treatments I found a rolli polli twice now walking around so maybe they are a super bug or somthing lol.

    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.

    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

    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.

    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.

    This stuff really worked to end the carpet beetle problem we were having. We didn't have a huge nest so it was able to get to the heart of the issue right away.
