During the summer we are extremely busy preventing our own bees from
swarming; consequently we are unable to help with bee related problems.
However, the following may be useful -
Are they honey bees, bumble bees or wasps?
Bumble bees are fat and furry/orange/yellow or white striped.
Wasps are bright yellow and black with no visible hair
Honey bees are as per the pictures on this web site.
Honey bees are the only ones that hang in a cluster on trees and hedges
and this is the ideal time for them to be taken by bee-keepers and
Local police stations hold registers of bee keepers who are willing to
come out and collect swarms
Also the British Bee Keepers
will have more information of local swarm collectors.
