The garden spray is a lot less expensive than elektor. I would spray it monthly for several months to make sure the mites stay away.That’s the active ingredient of Elector PSP. I sprayed the coop when I sprayed the birds. I want the sulfur for in the dust bath.
sulfur is likely line DE and will be a deterrent but not likely good in the long term. Sulfur is also an irritant so might not be completely safe
I hate pinched nerve pain!
