According to Paul Harvey, in one of his news briefs this week, powered
sugar is an effective treatment for varrora mites.  I was told that he
stated that according to a beekeeper in Oregan that it actually kills
mites. I did not hear this myself as I do not listen to him.  As close as
I can tell he probably broadcasted this on Tue or earlier.  I had a person
ask me about this, that is how I found out.  So is anyone familar with
this claim or this beekeeper?
