shimmering chickenwire octagons keep out
chickens and anything larger than a chipmunk
but not the predatory fingers of raccoons
nor chipmunks themselves

leaden hardware cloth squares keep out
the smallest rodents (even chipmunks)
and birds, but not bugs except praying
mantids and probably tarantulas

what’s needed is screening, no longer
made from wire but pressed or extruded
petrol-polysomething, to keep all visible
annoyances at a safe distance
