Aaron,
The bees who have the mites or had mites are not the issue. You want as
many bees who have not had mites to go through the winter. So if you can
get several months of mite free bees by treating early, you are better off
than treating late.
As far as the "wounds", I leave that to more experienced beekeepers than
I, but a good guess is that they are not in great shape for the winter and
will probably be the first to die.
