Re: Entrance trap
It's not a trap but I built a robber screen that can lock down a hive, also works great for a reorientation obstacle. The "slot" along the top of the screen's frame is approx. 3/8" that accepts a 1/4-5/56 piece of wood to lock the hive down, with a slight modification you can also leave a smaller opening. The frame is roughly 8" x 8" x 1". I run BBs with the entrance fixed a 4-4.5" so the screen works on all hives.
