We discovered our chickens had mites about 3 weeks ago. We sprayed everyone and everything with the Elector PSP and bagged and disposed of the bedding as soon as the product arrived. We had 1 hen die while we were on away on vacation. We repeated the process yesterday. Yesterday evening I sprinkled everything with DE before adding new (fresh purchased) bedding and afterwards I was covered in mites. This morning when I checked for eggs, the bedding was covered with creepy crawlies. How long after treatment do the mites die? Can I wait the recommended 10 days, or should repeat the process sooner?
