I am curious if anyone has used Minnesota Hygenic queens? They are very popular in the north especially with migratory beekeepers but I have heard a mixed bag when it comes to keeping them year round in the north.

If you have used them, I would be interested in the following:

1) Were they wintered in the north and if so what was your impression going into the fall, overwintering and entering the following spring?

2) Any thoughts about how they respond to tracheal mites?
