Have you any experience with applying oxalic more than once in the fall by
dribbling (also called drizzling)?  I heard some rumours that more than one
treatment per generation of bees could have bad effects, but nothing very
certain in that regard.

I had also heard that multiple treatments by evaporation did not have bad
effects.
