The ideal time to move bees is early to mid March when the population of the colony will be smaller than at other times and easier to manage.

Your local swarms officer will need to assess the site before any action is taken, but he is likely to suggest one of the following. If the colony is inaccessible he will remove the bees with a vacuum cleaner. They will be unharmed by this and the bag will serve as a temporary hive until the bees are transferred in to an apiary.

If it is possible to enter the attic and the bees are in a hanging position, a basket will be placed underneath, the cones cut and placed in the basket and covered with a secure net and they will be removed to an apiary.
