Bees are all dead in the hive. Mid-January they were alive and well. Now all dead. I have no idea what got them this time except for the cold.
I treated repeatedly for varroa mites
I took zero honey, leaving it all to them
I added a cedar pillow to the top to prevent condensation falling on the bees
I didn't wrap the hives this year however, since others seem to get by without doing that. I did add some insulation boards next to the hive though and snuggled two empty hives next to them for warmth.
I am undecided about this year. I may or may not try to get more bees for spring. I'm pretty discouraged.
