Sometimes the bees can pass trough a 6 mesh screen when it ihas not been
manufactured with precision.  This what a beekeeper experienced here in
Québec.  This is also why you find quite often bees in the pollen drawer of
pollen traps.  Would anybody know who actually sells 7 mesh?

I seem to remember one paper that said 6 mesh is large enough that yellow
jackets could get in, requiring the bees to defend the entire bottom floor
(yellow jackets hang outside my hives in the fall in fairly large numbers,
trying to find a way in). 8 mesh is commonly available, but 7 is also sold
at beekeeping supply houses.
