Up here, we've been noticing a lot less varroa than we would expect. As
with everything, there are years when they thrive and years when they do
not. Nature has its cycles.

That should be catching them all, if the screen keeps the bees away from the
fallen mites, and if you are using enough Pam to soak the falling mites.

See above.

Shouldn't be, if used as directed. It does leave a very residue that can
have a subtle deleterious effect on queen bee rearing, but should not leave
enough to affect mites much.

That may be a factor, but it may just be that the mites are having a bad
year.
Glad you are thinking about this, though. I am too.
If you are not having serious mite problems, maybe you should not be using
Checkmite+. Checkmite+ IMO, is only for situations where lesser measures
cannot be trusted to work.
