What’s a suggestion for mite control. I have straw and shaving on dirt floor in coop. About 3 inches thick. Keep coop nice a warm for winter and just rotate it daily. I’m having a problem keeping the girls free of mites. I’ve dusted them once already a few months back. What is everybody using for mites. I put diamatous earth on dirt ground in run and when I clean out coop and nesting boxes. How often and what to use. Please help. Excuse spelling
