Another principle behind these super storage sheds is that moths will
only enter such stacks of supers from the top.  So if your stack of
supers is open to the bottom (on a slatted floor, with mesh, for
instance) there is a natural 'chimney' draft of air up through the
stacks.  And the theory is that the moths don't/won't fly down into
the boxes if there is such an air movement.  Doesn't stop the mice,
however...
