Just gave the bees a good talking-to.
Younger Son is on holiday until Saturday evening and the bees are getting ready to swarm. I told them they must not even think about swarming until he is back.
Should they decide to ignore me and swarm anyway I am under instructions to follow them and keep them in my sight. As long as they stay in my view they are still mine (or YS's anyway). I can see me trampling through people's back gardens saying, 'Excuse me, excuse me, I just have to follow the bees.'
I have further instructions. If they stop, in a tree for example, I am to put the spare hive underneath them before banging the tree with a big stick - that should make them fall into the hive. 'Put the bee suit on first,' Younger Son reminded me.
