What I am trying to do is to find out if the peppermint is effective against
 T  mites.  I have been using the roll test about twice a year to check for
varoa and always treat in the fall just to be safe.   If I can be satisfied
that the peppermint is effective for  T  mites, I plan to try to find one
that will be effective on voroa mites.  I have been told that camphor and
eulyptus have shown some promise but I have not tried either.
