It is an entirely natural process that happens every year usually between May and July. There is something on my web site about it here.
I think the reason bee keepers are obsessed with it is that an unplanned/controlled swarm can reduce the honey yield.
As I have no interest in honey I'm not too bothered.
There are two types of approach to managing swarming - proactive and reactive.
Proactive, or getting your retaliation in first as I call it, is doing things before the swarming process starts.
Reactive is what you do when the swarming process has started and you try and control it.
Most years I hope to do the former but finish up doing the latter
Probably the main trigger for swarming is a lack of space so the simplest proactive thing to do is to give them more space and the easiest way of doing this is to add a super to the hive. Supers are where the bees produce 'our' honey and filling this up with hopefully reduce their swarming instinct.
The weather has been a bit odd lately but I thought I would have a quick look at the hives to see what is going on before it became cold again.

Apologies for shaky camera, although I always have my camera with me, I didn't intend videoing anything so didn't have my tripod with me.
