Swarming is the natural way for hives to split, most often occurring between the months of May and August. Whilst an imposing spectacle, there’s no need to panic.
Do you think you have a swarm of honey bees?
The British Beekeepers Association has an excellent page to help you distinguish between honey bees and other winged creatures, such as solitary bees and bumble bees: http://www.bbka.org.uk/help/do_you_have_a_swarm.php. It is vital that you identify the type, as swarm collectors can only help with honey bees!
Yes, they’re honey bees!
A local swarm collector should be able to help you. To find you nearest collector, please enter your postcode into the BBKA “Find a Swarm Collector” page: http://www.bbka.org.uk/help/find_a_swarm_coordinator.php
