I use Permethrin. Dilute in water and use a hand pump sprayer. Hit all the birds as I take them out of coop then clean out coop and drench that with sprayer too. Have all doors open to dry then put in new nesting material and bedding.
I don't clean out the coop seven days later but do hit cracks and corners with sprayer after spraying birds for second time. I do this once a year every fall. And yes, I usually don't realize they need it until I see mites crawling on eggs.
