Reasons for swarming
Natural means of colony reproduction
Colony too crowded
Unbalanced colony Queen getting old Absconding
Preparation for Swarming A week before actual event Eggs in Queen cells Queen cells sealed Old Queen ready to fly off Prime Swarm
Prime Swarm & Casts Prime Swarm – half the workers Casts – Virgin Queen plus
progressively less workers Viability of Casts ? Viability of parent colony ?

Impact of swarming
Swarm Prevention Regular Inspections -
weekly Young Queens < 2 years
old Room in brood space for
Queen to lay Room in super space for
nectar to be stored Know what to do when
Queen cells are seen with eggs or larvae
Mark & clip Queen ensures any swarm returns to hive
Mark and clip your Queens
Effect on Swarm of Clipped Queen
Swarm is not lost Workers return to hive Queen may return to hive Beekeeper must still take action
Swarm Control The Artificial
Swarm Many methods Colony acts as if it
has swarmed
Use of the Nucleus
Swarm ControlBasic Principles – (1)
Colony made up of 3 parts: Queen Brood Flying bees
Swarm ControlBasic Principles – (2)
Swarm control involves separating one of the three parts from the other two:
Queen from Brood and Flying Bees
Brood from Queen and Flying Bees
Flying Bees from Queen and Brood

Virgin Q flies out to mate
First VQ to emerge attempts to kills other VQs
Do not open BOX AFor 3 weeks
After a further week check for Q Cells
Swarm collection locations
Rest nearby Trees, hedges, posts etc.
Scout bees look for home Collective agreement Fly off Popular sites
Chimneys Roof spaces Compost buckets etc.
Swarm Collection Obtain appropriate insurance Obtain permission from the
landowner Ensure the public are kept away
from the swarm Retrieve the queen and the rest
will follow Move the bees into a box Invert the box near the swarm Wait for all the bees to join the
queen Take away and re-hive the swarm
Hiving a swarm In front of hive Directly into a box Check for diseases Feed after 2 days
Difficult locations
