Since I like to refrain from marring the surface of my woodware as much as
possible, and because I am cheap, I am thinking about using cardboard,
folded several times, leaving an inch or so opening in the entrance of my
nucs as entrance reducers.

Will the average strength of a 3 frame nuc be sufficient to defend the full
entrance by the time the cardboard is chewed through?
