Have you used this yourself? I'm' trying to figure out mites, also. In California. We never had a freeze this winter, so mite outbreak this week is massive. Have about 60 chickens, all free roaming. Need to treat over half an acre, can't catch them to treat individally, and they share all their water sources with dogs and cats. Also, have several batches of new babies running around. I drip Frontline on some of the more tame ones. Mites are so bad we track them into the house, now they are on our furniture and in carpets.
