I've been caught out by a swarm - got them into a temporary wooden box - any idea how long they might be ok to stay in that? I don't have another spare hive (yet!).
Do they ever swarm without a queen? I didn't think there was one left in that hive, just a lot of queen cells.
Full marks to my non-beekeeper husband who insisted that it was safer for him to don my beesuit and climb a dodgy triple-ladder into the tree.
