So, I'm new to chickens since June & have been getting a crash course. I have 3 birds in a smallish coop/run, but they range often in our 1/3 acre backyard which backs up to a lake. [Read: lots of wild birds].
I've already tried DE as preventative and have a horrible infestation of what I presume to be mites. I've put woodash in the run, and they loved it, but now I'm ready to cut my losses and go ahead with the big guns with Sevin.
I'll dust the birds, clean and dust (or spray?) the coop now and again in 10 days, but I'm still wavering on what to do with:
1.) the run - it seems best if the birds don't ingest the Sevin dust, if they've been treated, is it necessary?
2. ) their favorite hangout/dustbath spot when they are out is under my avocado tree. how long can the mites/eggs live without the birds present? Do I need to treat this area in some way, or just keep them cooped up until the mites die? I'm reluctant to put Sevin dust under my tree, and I'm afraid woodash would throw off the pH too much.
Thoughts?
