it's 100% my fault. We live in a small town and I thought I knew all the bee keepers in the area. The closest being about 2 miles away, and me having only one hive, I was not worried about robbing. So I set my extractor outside for the bees to clean up. I also had some supers with bits of honey left and I put them inside my bee shed (my bee hive is inside a shed with an outside entry) so that my bees could clean them out via the inside entrance. That worked well for a few days, but today I got home to find lots of activity everywhere and bees fighting inside the shed as well as on the landing board. The hive is very strong, but with the volume of robber bees I see, I'm worried that they will be overwhelmed. I sealed off all the supers beside the hive, sealed the top entrance, and put on an entrance reducer. I also piled some loose leaves in front of the entrance. Is there anything else I can do to remedy my rookie mistake? Can I seal off the entrance with mesh and feed the bees for a couple of days until the robbers give up trying?
