I hope that isn't the case, rober. Last year I had one of my colonies swarm Labor Day weekend. I have one colony that is so full of bees right now that I am debating on adding a 3rd super. If anyone has any better ideas I would welcome them.
We got a call from a neighbor last Saturday. He said he had a swarm of bees under his porch. After work I went over to see. The bees had set up house underneath the floor boards of his deck. (I hope that's where they are) We couldn't see where the nest was. I offered my help in removing deck boards and suggested removal asap. I feel like the swarm could have originated from my hives, although I haven't seen any evidence of that. There are feral colonies around. He declined. His wife has Parkinson's disease and the bees are creating a problem when they try to come and go in the car.
