I have successfully dribbled OA from a large graduated  syringe at the rate
described along each seam of bees.  This was done without the need to remove
frames from the hives.  The amount of mites it brought down was greater than
predicted my the model based on the fall preceding treatment.  It must therefore
be relatively successful.
