        We do have a similar system of control here in North America. Our
name for it is a "Varroa trap", it consists of an outer frame covered with
queen excluder. A frame of drone foundation is used, and one suggestion was
rather than waste the by-products, the frame is replaced in the hive after
freezing to allow the bees to reingest the dead brood. Obviously the dead
Varroa drop to the bottom of the hive. As an aside we do market these should
anyone be interested.
