   We have also experienced a few hives which are very thorough about
   chewing up and discarding such cardboards (not usually sticky boards
   since we cover them with wire mesh). We were inserting veg oil soaked
   corrugated cardboard at 7 day intervals. In most cases the 5 inch
   squares were mostly unchanged, or nibbled a bit at the corners. (A
   beekeeper did this on a larger scale, then abandoned it. We have found
   those squares nearly like new after a year.) A few colonies however,
   attacked the cardboard and all that was left in 7 days was the shreds on
   the bottom board. Many bees must have been involved.
     I wonder if the behavior is correlated with brood removal hygenic
   behavior.
