I cannot find a clear cut answer in my research, but was wondering if this part of the bottom board (top of the bottom board) should be painted? Of if the "lip" of the entrance should be painted? I have painted the "bottom" of the bottom board of course, but the "top" portion is not painted since its technically "inside" the hive except for the lip portion (landing entrance). I know that there are a lot of chemicals in paint and people mention not to expose painted surfaces to bees.
Can someone shed some light?
