WestGrove, Pa yesterday a swarm landed and they called me this morning. By the time I got there most of them were gone. I left a box there just in case. The LGO and queen juice seemed to greatly attract the straggler "scouts" that were still hanging around. That was very cool to see. Bummer that we were less than an hour late because I called the home owner and she said that they were still there so I went.
