Hi Waldemar
Acarine mite (tracheal mite) is endemic in Europe, but exists at only a
low level.
The dark European Bee copes very well with low levels of Acarine.
The bees, in general cope with the mites, but sometimes a colony gets
highly infested, such colonies are killed in order to remove the
susceptibility.
Treatment would be foolish as it would actually propagate the problem.
