I've been keeping bees for well over a decade now, and Varroa mite management and prevention of downstream disease vectors like deformed wing virus are consuming ever greater amounts of our time and concern in the community.

Personally, I've tried a number of mitigations with varying levels of success--most all resulting in requeening due to toxicity of treatment. At this point unless a truly successful new therapy is found it seems like a losing battle tbh. I meet monthly with beekeepers and scientists monthly for a few years now, an 99% of the time discussions involve Varroa destructor. It has that name for a reason...
