At EAS 2005 there was a presentation on doing drone removal for varroa
control. They used two drone brood frames in each hive. These were
removed on a 30 day cycle and replaced with a second set of two drone
frames. For the next 30 days the first two frames sat in a freezer.

This is the way to capitalize on the fact that varroa thrive in large cells.
Instead of making all the cells smaller (a huge undertaking) -- you offer a
couple of combs where they can congregate. Please note: 30 days is too long.
Better get them out sooner or the drones may hatch, and out come the mites!
