I was wondering if one combined the different varroa control methods would the results be additive. For example, has anyone used the combination of varroa tolerant bees, screened bottom boards, small cell, and drone cell trapping. I know that this would not be practical for commercial operations, but have any of you hobby beekeepers used a combination of these methods? Does the small cell only work with feral bees? I plan on starting with only 2 hives. Does anyone see a problem with trying to use a combination of these methods? Thanks for your comments.
