AT the risk of sounding like a complete bottom kisser, Dawg is absolutely right here. If they have mites already you should still dust the coop and everything. I didn't and got away with it, I THINK. I could be wrong.
Well if you're gonna bottom kiss....Dawg's is as good as any....LOL Sorry Dawg....couldn't resist. I too prefer seven and I only use it if I feel invisible creepy crawlies on my arms a few minutes after handling a bird.

  I was just so tired of picking them up and then picking bugs off myself!!! Even after the dusting!  Seems those critters like me just as much as the chickens....my kids never have a problem.  Me, I manage to get them crawling all over...even in my hair
