excessive moisture in winter hives is detrimental to the health of the bees

Never thought of it Bill, normally the dribble is done in fall, not in the
middle of winter.  Done before the bees are tightly clustered, so I doubt
that  a few ml of water would hurt.  My next article addresses OA
vaporization for midwinter treatment.
