Bee people, Brian from NY here, beginning beekeeper. The top bar hive I started last year did not make it through the winter, at least in part due to lack of honey (this year I'm feeding more, that's for sure). I opened the hive up a couple of days ago, and saw Varroa as well as the dead bees, and plenty of empty comb, light and dark. There is some comb with honey, I'd like to leave that for the new bees, and probably some cells with dead larvae. It's probable that there have not been any live bees in my hive for many weeks, and it's been pretty cold, multiple weeks below freezing. Does that mean that all the Varroa and their eggs are dead? Or should I take special measures to clean out the hive? Thank you.
