I really wouldn't be using that in a dust bath! Overuse of pesticides is how we get pesticide-resistant pests. If you just mix it into the dust bath, there's no way to be sure they're getting enough of a dose to actually kill off the mites, which means you might just be making the mites more durable against poisoning. If so, you'll get a mite infestation eventually, and permethrin won't work on them.
Plus, that's supposed to be used as a temporary treatment. I really don't think it's supposed to be used long-term.
