It's been mentioned before, although not on this thread, but diatomaceous earth (DE) works really well too (make sure it's "food grade"). Several years ago I had an ungodly lice infestation and started regularly sprinkling DE around the coop whenever I added litter, etc. The population dwindled and then disappeared. I made a light dusting of DE an occasional part of litter maintenance, and I didn't see a louse for years. (Oddly enough, I did see a couple last week for first time since then, but after another, long overdue dusting they seem to have disappeared once more).
