I had a dead out in October from a nuc that I got in April, it was cool and wet all season and this hive got progressively weaker even though I fed them all summer. When I inspected in mid October they were basically gone with a handful left. I scoped them up into a jar with alcohol and sent them to the state inspector. The letter came back today that they had tracheal mites. I have another hive next to that one that I thought was a little stronger. What would be the contamination factor and how should I treat them?
