As for permethins-- I have switched to using sulfer powder, and my cats like it when I rub them to sprinkle it on.
I have been reading about other alternatives, and though Ih ave not used them myself to prove it they work, it has crossed my mind that they might be useful around the chickens. Bay leaf, lavendar and mints/catnip including pennyroyal which is listed as a caution as it can cause problems in large dosages. My MIL always kept bay leaf in the flour-- apparently she was right. SO perhaps it works on other insects, too.
