Why do bees swarm?
When a colony has been very productive, it will grow and thrive until it outgrows their hive. At this time the bees will raise a new queen so that they can duplicate their colony. With the new queen secured, the old queen will leave inside a large ball of 10,000 to 15,000 bees. This swarm can weigh in the upwards of 10 pounds! The swarm will move to a temporary location, and remain in loud swarm for a few hours, or up to 48. The scout bees will leave to swarm to find suitable home for the queen. When the scouts return with news of the new locations, the swarm then moves to new location to set up a new hive.
