I had some serious robbing going on yesterday. It was my fault because I set wet supers out a few hundred yards away from my bees. That's another conversation. Anyway I'm throwing together robbing screens made from disassembled packages. I could build them 100% from the wood in a package but have supplemented with scraps laying around. It's labor intensive so not for the large scale folks. But, I hate throwing them away and they stopped taking them back for a deposit. Just thought I'd share to give others ideas on a repurpose for all those package containers most of us have.

Not being negative about your idea, but if you use wire screen you can leave them on all winter for mouse guards.
I have one setting under each of my hive's with wire screen ready when needed.

GREAT IDEA

That is the plan. The slots accommodate 1/2" hardware cloth too. Come fall, I'll replace the mesh screen at the sliding main entrance with hardware cloth to block mice.

Many people I work with leave robbing screens on all year and they double as mouse guards, just be sure they have a top entrance or something in the winter. They can get easily clogged with dead bees and they can get trapped inside and die.

I tried to design them so I could leave them on all year. The bottom screen slides open the same with as the wide gap in an entrance reducer. I leave the notch in the inner cover open all year except for late summer/fall when robbing occurs.
