The old original creosote is now banned but theyve replaced it with almost identical stuff with some of the nasties taken out, take your chooks out for a few days and hit the whole hen house top to bottom with this, will kill any mites on contact may require 2 coats. we also use diatoms but you need to give them a chance to work not instant.

Thanks for your advice everyone.
My chickens are fine in themselves, happily running around so I hope the red mite powder does the trick. If not I'll try some of your suggestions. I can't see any mites/lice anywhere on the girls or in the coop - very strange!
