Allow me to start with an excellent assessment by Bee Culture’s Phil Craft (BC July 2015): Perhaps beekeepers who have come to the craft in the last few decades aren’t aware of the effect varroa had when it first arrived on this continent and of how it earned its full name, Varroa destructor. Whatever the reason, every year, beekeepers all over the country lose colonies to mites and the viruses of which they are carriers, and they never know what hit them. They blame pesticides,or CCD, or habitat loss, and sometimes those really are causes, or at least significant factors. However, too, too often, the underlying cause is a lack of effective management, which allows a mite infestation to overwhelm a colony or weaken it to the point that it succumbs easily to other stressors. The most frustrating thing about these losses is that they don’t have to happen. Watch Dennis vanEngelsdorp explain why mite management is critical for colony survival, and which methods work or don’t at https://www.youtube.com/watch?v=4bm3Y4t1NwQ
