Here is a presentation provided at our last meeting (February 2023) regarding the Varroa Mite situation.
The mystery continues!?
Two poly hives have lots of bees under the bottom board. We checked the two busiest hives and both didn’t have a single swarm cell.
The queen looked great and fat like a laying queen should. The first and second pic shows the huge number of bees under a third hive.
We boxed the bees in a nuc from another bottom board. The third pic shows nosema type stains in the Back of hive where the bees were clustering.
So I can think of two options.
