Hardware cloth under greenhouse to keep out vermin
Has anyone here used galvanized steel hardware cloth under their greenhouse to keep out moles, mice, rats and other assorted vermin? If yes, what size mesh and what guage wire was the mesh? A friend has enough 23 gauge steel wire 1/4" mesh that he will give me to do the entire subfloor (8' x 24').
Does this sound like it would do the trick?
