I built my tbh with a screen. I'm in north Georgia, it seemed that it made the hive way to open to the elements. The package I installed didn't last long. They built a a comb or 2 then died out or left. It was early spring and still a bit chilly. Can you make a removable cover for the bottom?
Note to self: don't get into a fist fight with a cactus. Command this tiny ad to do it:
