Iddee,
I know with the tree Trapout it was a new swarm. The owner contacted me within a week. He knew when they moved in because he saw them ad he and the neighbors dog were stung. Most of the time I was handling them they were nice. My wife was stung this morning while we were putting them in the medium and they made me abandon my riding mower a little while ago. Had to wear my bee suit to finish cutting the area in front of the hives. I will bee re queening it soon.
