I found them less than a meter off the ground on a low branch. Couldn't be easier! A sharp shake of the branch and they dropped into my swarm box; picked up a few stragglers, closed the lid and off I went. I quickly got them installed in a hive at home where they can settle in before I can determine what to do with them.
Yesterday I fed them some syrup and put a frame of donated brood from an other hive and so hopefully this will be the boost they will need to get properly going; not that they will need it - they has already started to draw out the foundation in the new hive.
