Last year I split my one hive into two to prevent swarming having had one swarm the previous year - my first in beekeeping. Splitting the hive was successful last year but two is enough hives for me so that option is not available. This year I have already had a good harvest but I have also had both hives swarm twice in the last three weeks. I gave one swarm to a local keeper but it was a real palaver getting it out of the trees so the other swarms I left to their own devices. As I write I have one swarm exiting from No1 hive two days ago clustered in the front garden and one from No2 hive this morning in the back garden. Is there a way of preempting all this by dividing the population while it is still in the hive so I can give the surplus away to a suitable home before it swarms and causes a local nuisance?
