I recently discovered that my Langstroth hives have both died over this past winter. In the video above, I perform an autopsy on the hives to try and determine what killed them.
In the first hive, it looks like the bees may have starved after a really long and cold winter. I believe I missed an opportunity to feed them in early spring. They only had a tiny bit of honey left and it was on the opposite side of the hive. In the second colony, I actually removed 10 full frames of honey from the two deep boxes – more than enough to survive the winter. I suspect the chalkbrood that had plagued them in the fall didn’t allow them to build up their colony to a size that was necessary to survive the winter.
I’ll be on the lookout for swarms this spring to get new bees to populate these sad, empty hives.
