Now that there are two treatments available for Varroa mites, should there
not be some thought into rotating the treatments to reduce the chances of
resistant mites? For example, spring treatment with Check-Mite and fall
treatment with Apistan?
Since coumaphos is a nastier chemical, maybe only one treatment in four
(fall of odd years)?
