First swarm of the year for me (I was offered one a week or so ago, but being invalided at the time, could not get it). It was a bit awkward, sat on both sides of a trellis, close up to a green house.
I used a dustpan and brush, swept up as many as I could, and the rest kindly went into the box of their own accord over the next hour.
It was fairly cool and cloudy, which helped as they clustered up quickly in the box.
I no longer have a spare hive….
