Question: will this work on large roaches?
Document: Nothing. Not one word of caution or toxicity is addressed. They also neglected to include all the sticky tape that holds them up on the wall (assuming they go on the wall). They sent 5 pieces for 10 discs. Gentrol does work in combination with extreme cleanliness and another bait program- but it takes a while and this product will not kill roaches- only makes them sterile so they reproduce slower.
These discs reallllly work well. I used to shell out $125 or so every 3 months to an exterminator for an infestation problem. Even after extermination, baby roaches would re-appear everywhere, as though they were taunting me. I figured out that the gel bait the exterminator used was killing the roaches, but not the eggs. These discs are like population control - it sterilizes them. I think it even mutates them, as I had seen a few weird looking ones stumble around stunned.
I live in an apartment building that has roaches. I placed these under the sinks and places where I thought roaches may infiltrate from outside our apt. I am hoping eventually that they will help alleviate the other tenants problems as I have solved mine with products purchased here at amazon. Read my other posts to see what took care of my creepy crawlers. I have used growth regulator products before for roach control quite successfully, especially good for german roaches! May take a few months but they work!
I don't know if it is the gel or this, but it seems to be less roaches in my house.
It was easy to install and seems to have solved the problem with roaches. It did take about 3 weeks in conduction with gel bait.
Highly recommend. Great product at a very good price - has helped us clear our lake home of all roaches.
We live in the woods and this is the first time in 15 yrs that we have seen wood roaches in the home. This system seems to be very easy to use and very effective.
After tenants were evicted, we used this in combination with a control bait gel, no more baby nasty bugs, means no adult roaches. It works fast and efficiently when combined with bait type insecticides.
my tenant said she have not seen any, not even 1 baby roach. No more babies means no more roaches. I will make sure I treat the house every 6 months with Advion and Gentrol combine.
I bought the ten pack which should have been way more than enough for my 650 sq ft apartment, but laid down all ten in the roach areas and here I am a month later with more baby roaches than ever and huge German roaches bigger than when I laid these down. Did not affect the roaches at all, very disappointed.
Answer: yes
