Cleaner Bees

I've got my bees at work cleaning up the frames that were centrifuged last year to get the honey out.Since that whole event was a catastrophe of timing, FAR too late, I held these sticky frames over the winter in Rubbermaids, which worked really well.  Now it´s warm I set one out by the hive with the lid off for the cleanup crew.The bees cleaned out this whole boxful in a couple days, except a couple spots.  Licked totally clean, no longer even sticky to touch.The cleaning job is of an indescribably high quality.    The frames go from this:to this:Pristine.  And a boxful in a couple days.  They get a snack out of it, too.
