Be sure to read the label directions of each product for mixing the permethrin 10 concentrate. This one lists 2 different concentrations to treat mites on the chicken ( 1.5 ounces or 45 ml per gallon) and another less concentrated for the premises/roosts, nests (0.73 ounces or 24 ml per gallon of water) :

Please check my math. Each chicken should have 15 mlof spray, and repeat every 7 days until mites and eggs are gone. For coops, nests, and roosts, apply every 2 weeks. Bedding should also be removed from coops and nests.
