The poison is in the dose...

This is a typical organophosphate. Very effective at killing. Anything. I would recommend this to a pest control professional but never to a homeowner. The WARNING label should be explained to those non-professionals out there that think if it says 2/3 oz. in a gallon is recommended then 2 or 3 oz. in a half gallon is better. This is a very strong insecticide. Organophosphate insecticides irreversibly inactivate acetylcholinesterase, which is essential to nerve function in insects, humans, and many other animals. It was used as a nerve gas agent by the Nazis in the 1930s and in the Tokyo Underground attack in the late 1980s or early 1990s. It has a strong "cheap paint" smell that subsides in an hour or two. A little goes a very long way and if you know what you are doing, it is exceedingly effective at knocking down even the toughest roach populations.

My neighbor had a dog under her house that was left unattended for awhile. She finally got rid of the dog and her children started bringing fleas to my home. I was wondering where the fleas were coming from. I stepped into my backyard and I must tell you, my white socks looked like a pair of Brown dress socks. I ran to Lowes and tried about $200.00 worth of products that did not work, a friend of mine gave me a 3.2oz bottle of Catalyst and that knocked the fleas out in no time, but I needed more. I googled the products name and came across this site and man what a blessing. When mixing with NyGuard IGR it diminished my flea infestation in no time and also my neighbors. It's well worth the money if you have any problem with any type of pestilence!!!!! Works good on roaches as well!
