I had my first swarm today, in my backyard in the middle of a raised garden bed. I was shocked to say the least. I picked them up, mulch and all and put them into a hive body with unpulled foundation. I got most of them and at first they all clumped up on the outside. They flew around in frenzy as well. It seemed to be a bit of excitement. I have just returned back from a evening out with the wife and there only seems to be a few clumps of bees here and there and not a swarm in the box.

Is it too late for this swarm? can I lure it, and if not what can I do to make them stay next time? Thanks
