Does anyone have any ideas. My entire hive left in mid march. Someone suggested it might be the african hive beetle, but I'm not sure. The honey left behind (1 1/2 shallow with some in the deep) was not sour or frothy. I didn't see evidence of the wax being eaten, except in one area where I found a mouse nesting. I didn't find any queen cells. I cleaned the bottom board in early March and the bottom board contained only a few dead bees. Any ideas on what could have caused this?
