Hi Pav,

It seems clear that Bob may be in error.  We know that varroa reproduce in
small cell colonies to some extent and can be found within them. However the
bees are capable of controlling the situation and crashing doesn't happen.
And from what Barry S. has said it appears that is what is occurring. If
Barry S. isn't seeing DAMAGE (my emphasis) by now his bees are most likely
controlling varroa naturally. As for Bob I wish him well with SMR. I see SMR
as trying to swim up a water fall, totally unnatural and impossible to
maintain in the long run (I could be wrong).
