The arrival of better weather and the relaxation of restrictions promises a much happier summer for our bees and ourselves. Swarms should be anticipated (if they haven't already arrived - see below); so we should be considering suitable prevention, control (and recovery!) measures.
This one originated from a feral colony in a neighbouring church wall, with limited scope for prevention. With strong nectar flows (at least where my bees live), it's important to consider supering your colonies if they are running short of space..
The British Beekeepers Association has a useful guide to swarming for the public, including a map of where to find your local swarm collector (see www.bbka.org.uk/swarm ), and a handy guide to Bees in Buildings (attached).
