This thread is a couple of years old. Not sure if they got rid of their mites but this was the first year I had them in one coop. I tried several things but to know avail. I was getting worried about the birds. I bought and tried permethrin. It works. It took several weekly sprays because it doesn't kill the eggs but when the mites hatch out it does so repeated and thorough spraying is a must. I sprayed everything, walls, ceilings, floors (I use shavings in some of my coops), inside and outside of my nest boxes, on and under the roosts, everywhere, all cracks and crevices where mites can hide. I finally got rid of them.
