Swarms
Bee colonies can divide, one part of the original colony will remain in the hive and the other will fly off to find a new 'home'.
a swarm of bees will cluster temporarily in one location, and for the non-beekeeper can be an alarming and worrying sight.
If you discover a swarm, immediately contact either your local police station or your local council pest control officer. They both have the details of the Association Swarm Officers, who will be contacted and will come and remove the swarm as quickly as possible and find it a new 'home'.
