Have you considered a solid bottom board under the screened one? Got this
idea from Chris Hayes at one of his workshops. The only thing open to the
elements is the space between the two boards on one end (I reverse the
direction of the solid board, so that its "opening" is to the back of the
hive). Makes it easy to close it when vaporizing, treating with Api Var or
when preparing for winter - I just stuff a length of a 1/4" pipe foam
insulation which fits just right into the slot.
Now, does it negate the efficacy of a screened board? Are mites able to
crawl 3+ inches through the junk that accumulates on the solid board
below? Don't know, but I doubt it and all my hives are strong. Though I
notice a few SHBs here and there, I've never had to deal with an overrun
hive because of SHB (my hives are 2 hours north of NYC). We've had an
exceptional drought condition in NY this past few weeks, so perhaps that's
also keeping SHB in check - bees are intensely patrolling the periphery of
each hive against all robbers.
And as someone has already pointed out, squishing the isolated SHBs on the
inner cover makes a satisfying sound under one's thumb, :-)
