Mesh Reducers

I came up with these after the so-called robbing incident on Mary. I wanted to reduce the entrance but maintain air circulation. The answer was wire mesh.

Mainly I hoped to lessen the pressure from Wax Moths & robing. The hive would still vent as fully open yet the entrance could be open only several inches. I though at first the bees would fill the mesh with propolis but they never did. It seems to work so I'll leave them in for now.
