How, exactly?
My impression has always been that by the time one can actually see varroa
on bees when inspecting a hive, the hive is already irrevocably doomed.
Drop counts and shakes/rolls are how I thought we monitored varroa so that
we could gather useful actionable data, and avoid having things get out of
control.
(Or do I need to visit the ophthalmologist? He said I had "Presbyopia", but
I told him that was impossible, as our family have been Lutherans since the
1500s.)
