I recently moved my hives from cinder blocks next to the woods into the sun and put them on an old exterior door supported by blocks. Since them I have noticed every morning several dead bees laying around on the door. The white door makes them readily noticeable. At first I thought they were drowining casualties, as the panels in the door collected dew. I drilled drainage holes to remedy the pooling but still see no reduction in their numbers. I'm not sure if the bees I'm seeing now were always there before, just un-noticeable in the grass around the hives, or if I have a problem. I usually see about a half-dozen or so around each hive in the morning. I know there is a natural attrition which increases in the winter up North, but I live is So. FL. This is my first winter keeping bees here where we don't get much winter. We even have a winter honey flow when the oranges bloom. Any FL beeks want to weigh in on this?
