Only the Beekeepers are deployed on the battlefield initially. In the Shooting phase, the Beekeepers can decide to release the bees. The bags of bees can be thrown up to 8". Place the Bee swarms on the spot you wish to throw them to. This may take them into Close Combat with an enemy.
After the Bees have been released, they will move using Fly in a random direction as determined by the scatter dice. They will engage in combat with any unit they encounter, friend or foe, except other Bee Swarms and Beekeepers. If a Bee Swarm encounters a Beekeeper, they will come under the Halfling player's control and will fight as a normal unit from then on.
