My bees seemed healthy last Fall with a very small mite count. Put shop towels with wintergreen for the trachaels and fed 2 gallons 1 to 1 sugar water to supplement the full super of stores on each hive. I live just below Charlotte.
In the last 2 weeks I've lost many hives. Some say it is CCD, but I wonder. Most of the hives only have a few dead bees on the SBB, and a handful in the starved position. No brood, no stores anywhere inside.
My questions are: What is the sequence of events in the hive when the varroa gets the upper hand? Same question for Trachaels.
