Linda,

Here is the thread where B54 describes his use of IGR.

I share your concern for pesticides around cats.
Permethrin (the long-lasting synthetic), is one that is safe for dogs but deadly to cats.
Pyrethrin, when the label is followed, is [relatively] safe for both, I think it is still used in cat flea shampoos (but I might be wrong).
I can never remember the names and have to Google them whenever I read a pesticide label.

Steve
