Forever the optimist, I'm really excited about this new product to deal with varroa mites. Vadescana is the ingredient in the product norroa.
It silences the gene that allows varroa mites to reproduce. Evidently it doesn't kill them but keeps them from reproducing.
Don't ask me any questions. Just google it and read about it for yourself. I just found it today and wanted to share it with you. I suspect it will be a very hot topic at this year's OSBA state convention in Bend October 24-26. As far as I know, only Brad York is going. Looks like a really good convention.
