What is the average lifespan of the varroa mite (Varroa destructor). It's a simple question that I don't have a answer to yet. I know they have a 12 day reproductive cycle, but not how long they can live. What got me thinking about this is; how long a break in brood rearing is necessary before all the adult mites die off?

For example, if the mite only lives for a couple months, how can there be any mites left to reproduce after an extended break in brood rearing like we have in the cold northern states. My bees have all shut down brood rearing and won't start back up until late December or early January. This gives me a 2 month window in which there is no mite reproduction.

If you know how long they can live for, let me know.

Thanks,
