I had a very good rain today. I hope there is results from this.
I have noticed the bees looking to rob. This usually means the nectar flow has slowed down. While working in my barn today, I noticed bees on some empty supers. There was nothing in them but they were looking for some old honey.
When the nectar flow stops and robbing begins, this is when AFB gets passed around. Make sure to deal with any weak colonies that may have this disease.
