Swarm indicator for the beehive

Swarm indicator for the beehive. This indicator helps you act in time when your colony plans to swarm. The indicator must be mounted over an entrance opening of approximately 5.5 cm by 2 cm. (This size is standard on the BeeFun polystyrene hive components with entrance.) When the bees are preparing to swarm, they move energetically toward the light through the clear cup. Under pressure from the bees, the clear cup will come off the tube. This is the signal to take action to prevent swarming.
