i use DE in all our coops and one of them got a severe mite infection anyways. Probably due to wild birds and having the pen top only covered in deer netting. DE will not knock down a mite infection. i used Adams flea and tick spray on the nest boxes and Poultry Dust with permethrin inside and nest boxes and in the coop under the bedding. Then sprayed the birds with a mite and lice spray and gave them spot-on ivermectin.
Still need to thoroughly treat the coop, but what i have done so far has gotten it down to just a few stray mites. Those things are nasty! It went from no apparent mites to a full-blown infestation in no time.
