Swarming is a natural process in the life of a honey bee colony.
Swarming occurs when a large group of honey bees leaves an established colony and flies off to establish a new colony, essentially creating two from one.
The age of the queen bee is an important factor that determines swarming.
Older bees have a swarming tendency.
Bees also swarm when the hive becomes overcrowded and the queen bee does not have enough space to lay eggs.
