Came home yesterday and my back porch was covered with flying bees. Swarm was coming in to one of the nucs on the top rail. Got video of the swarm after taking the box. You can see the bees with their rears in the air fanning like mad.
Check a box out in the woods and it looks like bees were using then found a swarm in the front yard near dark. All this from that cold snap we had.
