1 Pint Gentrol Concentrate IGR Insect Growth Regulator

I had a minor problem with German Roaches in the kitchen and the bathroom, but mainly the kitchen. I mixed 1 oz of Gentrol and 3/4 oz of Suspend SC and the roach problem seems to be going away I only see a roach every once in a while in the bathroom and the laundry room. I even asked family members if they had seen a roach and they said no. I was preparing food in the kitchen and didn't see a single roach crawling anywhere not even in the stove clock. First time using this product so time will tell, but it seems like when I combined this to an insecticide it actually was showing the results I was hoping for compared to just using the insecticide on it's own. I will probably give an update review on this product since one application should last 3 to 4 months as the product claims.

I had been battling a drain fly infestation coming from a former leak below my basement slab. While the leak was virtually eliminated, the flies set up shop in the soil and every moderate rainfall leeched enough moisture to revitalize their habitat. I had been trying for the better part of two years to get rid of them, and had tried just about everything. Two treatments of this stuff two weeks apart and they are effectively gone. My plan is to keep using it every couple of weeks until the bottle is empty, and hopefully the larvae will have been fully eliminated at that point. This stuff is expensive, yes, but pales in comparison to the hundreds of dollars I'd tried on more conventional treatments.

Worked great! Bought it to aid in killing bed bugs. Brought home from a hotel stay. Treated once mixed with cyzmic cs and again a month later. It's been a year and I still don't see any bugs! But we didn't have a bad infestation. We caught it early and I did a lot of research online.

I think it's working, but the old bugs are still there. Time will tell, I have hope.

I knew this product would work because it was recommended by the local pest and weed store which has been in business for over 30 years. But because some pests like Bed Bugs become resistant to pesticides, you have to use 2 ounces per gallon of diluted pesticide according to a newly released study. The label does does not have this new info. Even using 2 ounces with Suspend SC pesticide, I have a few "stray" bed bugs left. Did additional research and found out that adding a "kicker" such as MGK Exponent to pesticide solution makes the pesticide and IGR work more effectively. (Bayer Pesticide and MGK websites along with other sites) MGK Exponent actually short ciruits the bug's imune system, even on resistant pests, allowing the pesticide and growth inhibitor to work. I have also ordered MGK Evergreen (organic) 1% Pyrethrin Dust Insecticide and a duster bulb. A co-worker said after having her apartment was treated twice by professional exterminators, she had a few "stray" beg bugs left. And after using the Evergreen, it killed the remaining beg bugs. Apparently the organic Pyretrhin works on pests that are resistant to synthetic Pyrethrins. Hope this info helps. Also since you have to use 2 ounces per gallon, its far cheaper to buy the 16 ounce bottle which costs over $100.00 at local pest supply places, if they will sell it to you a non-licensed person.

great to tank mix with temprid for excellent roach control

This stuff is not cheap but I will say I had a major German roach infestation and ever since I laid this down about 2 months later not a single one. If you hate roaches this will definitely kill them I wish I could use it outdoors but it says it won’t work outside

I have been battling drain flies for 3 years. I bought this as a last ditched effort to get rid of them before calling in a plumber. After researching the internet and trying every do it your self drain cleaning technique suggested (bleach, hot water, biodegradables, drano, drain brushes, etc) I could not get rid of them. I finally bought this because one website suggested cleaning the drains and shower/tub every night then spraying with an IGR. Well I sprayed every night for about 2 weeks and then I started noticing the dead larvae in my shower in the mornings. Then one day while spraying my shower I discovered a dying larve wiggling out of a channel at the bottom of my shower door VILOA!!! I had found the breeding ground. Thanks to this product I was able to identify where they were actually breeding (absolute must to eliminate them totally) and finally get this under control. The shower door has been removed (the channel/track looked like the inside of a nasty pipe) and I've seen one young fly in the last 3 days, as opposed seven or eight daily during the winter and too many to count in the evenings and summer.
