I did it for two years and found it to be helpful (no other treatments
were used). The hives all overwintered, and though 3 of the 7 died, it
didn't appear to be a mite issue, but run-of-the-mill starvation. The
last two years, I've had trouble getting them to draw and use the
drone frames (the green plastic ones). They store honey in them, or
ignore them. Why these years are different, I don't know. (I did have
a baby a year ago June, so I've been a less-than-attentive beekeeper
for the last two seasons, however.)

Nick Calderone of Cornell has a paper on drone removal for varroa
control: http://www.masterbeekeeper.org/pdf/dronecomb_exchange.pdf
