Yes! It was not a big swarm, as it was about the size of a volley ball and was clustered on a deck railing when I got there. But the people who owned the cabin were great! Whew!
I also discovered a colony in an older travel trailer on the property, so I believe that is where the swarm came from....the swarm was not 50 feet from the travel trailer! I am going to have to remove the aluminum siding off of the travel trailer to get the colony. I am doing that next weekend, as they want to spend Mother's Day at their cabin.
