I've used Concern DE for a while, putting it in pet food when they have worms and also around their bedding to help with fleas. I got it in the garden department of the place I work. It's labeled as an insect killer, but I've been assured that it's safe (I tried it myself - wanted to make sure before giving it to the cats).
I've wondered about using it with the chickens in case of mites, but wondered about it killing off the bugs the chicks like to eat as well.
