10578 Gentrol Complete EC3 Insecticide and Growth Regulator, Orange

This is our second purchase. We had roaches in my mother's house for so long it was just commonplace. She'd say, I can't see them so I don't know what your talking about but they were bad. Finally after years of liquid traps and sprays and fogging, this product did the trick, within days they were gone and not just gone but GONE! and stayed gone for six months. We just started seeing a few a couple days ago and knew we should have ordered sooner but we sprayed today because we had the opportunity to leave the house for a few hours with the pets. It is strong and you will definitely need to leave for a several hours but I guarantee if you have a roach problem this will reduce or I should say eliminate. Going to spray outside as soon as the rains stop.

“One (1) ounce of Gentrol mixed with with an ounce of Demand CS both sold on Amazon) and a gallon of water will kill every roach you have graveyard dead. “ This is what a fellow reviewer wrote, and it is so true. I had a family member move in and they brought friends. 😳 I was so freaked out in just 2 weeks , it was horrible. This cocktail works! I’m so grateful to the gentlemen who shared this, yes it smells bad but like he said it’s a poison. Wear a mask and gloves and go out for the day to air out the house. It’s been 8 months since I sprayed the inside and outside perimeter of the house once a week for 2 weeks. No unwanted company… 👀

October 25. We have a heavy roach infestation. Months ago the landlord completely stopped doing pest control. At least for the last year treatment was spotty. Early morning and late at night when the roaches come out so does my mix of demand cs. In 1 week we're seeing far less. I spray every room near sockets Alexas and other warm spots. I spray perpetually dark places like behind mirrors pictures. They are far less abundant. I barely see them during the day now. I bought the liquid concentrate igr gentrol and it came today. I've seen the reduced colony with the disc's in the past. Tonight I mixed them together and so many roaches came out of hiding. They were publicly dying. I'll never go back. I'm excited for a potentially roach free home again. This particular one has an insecticide in it. Turn on the bathroom and kitchen fans before you start mixing. Put on a mask. Hell open the doors and windows. 2 of 3 of us were sneezing. The smell/ fumes are intense. I'll tell you how it goes. Nov 16 They are everywhere. Out of hiding. They are dehydrated. Paper thin. Deformed and disoriented. They are still dying. I don't see anymore babies.

This product works great, like having the professional come out to spray for ants! I have a constant problem with ants and had to pay $250 for the professional come out every three months. Not anymore! I just use it twice a year now, when the ants want to invade the house again. Now the ants are totally under control.

I have a problem with waterbugs in my area. I buy this product specifically for the control of waterbugs. I combine this product with my insecticide when I spray and it will be months before I see another waterbug. The majority of the time, if I do see a waterbug it will be dead on the outside of my house where they tried to make it in. If by chance one does make it inside my house. I find them dead dead dead. I have been using this product for about five years now or more. I always try to include it when I spray. The price is expensive but for the amount that you get, and for what it does, it is worth the price. I have purchased this product on other websites for more money. Then I found it on Amazon at a better price, and this is where I will continue to get it from in the future.

It seems to work very well, and I was able to wipe out the infection along with discs made by the same company. I haven't seen any roach for months already.
