The Wonder of Bees with Martha Kearney - Season 1 Episode 3

Spring has well and truly sprung and the hives are going from strength to strength, but that brings with it a problem of its own - the swarm. As the colonies become overcrowded, the bees become likely to depart in a swarm with the queen, leaving just a few behind to rear a new queen. It's a natural process, but for the beekeeper it can be a disaster, leaving the hive all but empty with little prospect of a harvest of honey.
