Swarms and Swarming

A swarm of honey bees settling in a tree

Swarming is the process by which a new honey bee colony is formed when the queen bee leaves the colony with a large group of worker bees. In the prime swarm, about 60% of the worker bees leave the original hive location with the old queen. This swarm can contain thousands to tens of thousands of bees. Swarming is mainly a spring phenomenon, usually within a two- or three-week period depending on the locale, but occasional swarms can happen throughout the producing season. Secondary swarms, called casts, may also occur. These are smaller than the first, or prime, swarm and are headed by a virgin queen.

Swarming is honey bee colonies’ natural means of reproduction. In the process of swarming the original single colony reproduces to two and sometimes more colonies.

Do you need help with a swarm?

In the past the collection of a honey bee swarm would be co-ordinated via the Swarms Liaison Officers of the WBKA Branches, whom you would initially contact. However there is a new process in place managed by the British Beekeepers Association (BBKA). All swarm collectors have made their location and contact details available that are displayed on a map. By putting in your location on the BBKA Swarm collector’s map you can see the details of swarm collectors local to you and contact them directly. Access to the map is below.

However before you consider contacting a local swarm collector please read the ‘Is the swarm honey bees?’ section below carefully and try and identify whether the swarm you have are honey bees as swarm collectors are unable to help remove any other insects such as solitary (bumble) bees and wasps.

Identifying Honey bees – and a link to the BBKA Swarm collector’s map

To determine if the swarm that you need help removing is honey bees please follow this identification check-list on the British Beekeepers Association website.

At the end of the identification check-list is the map of swarm collectors. Enter in your postcode and you will see details of swarm collectors nearest to you.
