Hi Barry!
 
I just visited the web site you suggested and I can learn a lot there.  As
for the over kill, I ment that when all said and done, I was going to
alternate , eg.  formic in the spring and apistan in the fall and it would
be only if need be.  Probably by doing drone trapping method I would only
have to do the fall treatment.  I am in a very bad area for varroa mite,
and we are just new to the situation and how to treat it. I never knew
about varroa untill this year.
 
Thank You, and I need all the help from expereinced beekeepers I can get!
