I was also concerned about the indigestibility of cornstarch. Eric
Mussen of UC Davis said that it is a concern in colder climates where
the bees cannot fly out, but otherwise it is a temporary situation and
does not amount to a problem.
However, the powdered sugar may get 90 percent of the mites on the bees,
but the majority of mites are in the capped cells. I am trying three
treatments, figuring 90-90-90 will do some good. Any comments on this
conjecture?
