You can install a robbing screen, and when I had some persistent robbing I only managed to stop it when I draped a bed sheet over the hive for a few days to totally confuse the robbers until they gave up.

I don't have any of that that is metal only plastic and they have chewed through that before on something else. I don't want to fully close it tight as it's going to be 90 the next few days and they are already bearding at 2:00 today so I want some air flow. I may see if I can crisscross the 1/4" mesh to over cross enough to block bees out but allow some air flow out too.#8 is hard to get. Window screen will do in a pinch. Close the notches with duct tape. Are you having them clean wet supers above the inner cover? J
