I use permethrin spray and dust. It doesn't kill the pests eggs so repeat thorough spraying is necessary, ceiling ,walls, floor, inside and outside of the nest boxes, on and under the roosts, any cracks and crevices where the mites can hide, everywhere. This is what has worked best for me and I have tried a lot of different things. I initially used the premixed in the bottle but now use the concentrate and mix it with water in a gallon sprayer. I had some birds that looked terrible and at first I thought they were molting but upon further inspection found they were covered with mites. Luckily they were in only one coop but I sprayed all of the coops. I dusted the birds with permethrin dust. Now the birds are beautiful again.
