Box traps have 4 shiny black sides, 16 x 32 inches, suspended by legs 24 inches from the soil. The top of the box trap is a 32 x 32 inch metal screen. Do not use a plastic screen as it can be damaged by birds. At the bottom, 2 rectangular 32 x 20 inch screens are fastened on opposite sides and slanted upward so that a 0.
