>>>  Plus, if broodless due to cold what impact does the tightness of the cluster have on % of mites killed?    If they have brood Randy's mite model says interval does not matter.       .      .     .    <><><> At a meeting several years ago Jennifer Berry, in a presentation, explained the way to treat mites in my southern area ( southwest Alabama) is to cage the queen for two weeks, wait another week, and then treat the colony as if broodless.  The three weeks from the beginning of caging the queen would allow all the bees that were capped to emerge and not enough time for the new brood to become capped.  Therefore all the mites in the colony would bee phoretic.
