Well, h*ck. All my bees are dead.
In SE Michigan, getting ready for winter. Had combined a weak nuc w/ the big hive about a month ago. Plenty of honey, lots of bees. They were fine a couple weeks ago. It's been in the 70s for about a week. Today, they're all dead in the bottom.
I was going to treat w/ OA vapor today, but nope.
Disappointing for sure. I'll try again in the spring.
