Have any of you beekeepers tried spraying the frames with undiluted cooking oil--such as canola or olive oil?
This would suffocate the mites and their eggs while giving the bees a needed helping of fat.
Dormant oil has long been used to control mites on fruit trees,but it is a petroleum product (still perhaps less toxic than synthetic miticides or formic acid.)

FYI, here's an article in the /San Diego News/ with the title, "Bees in
more trouble than ever after bad winter":

Luckily, I had lots of honey bees around last year, so I'm keeping my
fingers crossed this year. I've been trying to establish a population of
blue orchard (or mason) bees in my yard, but I haven't had any luck.
Instead, I've been breeding tons of leaf-cutter bees, it seems.
Well, I'm glad to have leaf-cutter bees around, but they don't emerge as
early as the blue orchard bees - or even as honey bees, apparently (at
least, I usually see a few honey bees - only a few - around on my
earliest-blooming fruit trees).
