Varroa destructor mite management is the most critical welfare and survival issue for managed honey bee colonies globally, requiring evidence-based integrated pest management approaches.
Varroa management is the defining welfare responsibility of modern beekeeping. Beekeepers who do not treat for Varroa condemn their colonies to gradual destruction — the mites reproduce in sealed brood cells, weaken individual bees, and transmit viruses that cause developmental abnormalities and immune collapse. The welfare of every bee in an untreated colony deteriorates as mite loads increase. Responsible beekeeping requires monitoring mite levels regularly using validated counting methods and treating when thresholds are exceeded, using evidence-based treatments appropriate to the season. The welfare goal is maintaining healthy, mite-controlled colonies where bees can function normally and survive winter.
