The report of Larry Krengel  P30LEK1@NIU struck me as interesting.  Not
the part about Varroa resistance, but the fact that menthol apparently
was effective in knocking Varroa down to the bottom board.  This is the
first time I have heard about menthol acting on Varroa; it mostly has
been used for tracheal mites and I believe still labelled only for that
use.  Another piece of the Varroa puzzle to remember is that even though
mites are knocked off by chemicals, if they are not killed, they often
can get right back on the insects.
