Honey Bee Swarm, how to recover a swarm and return the workers to the original hive

Swarm Returns to Original Hive; I was asked by a documentary company to make a high def video of a swarm departing, the queen, the swarm in swarm mode and the arrival of the swarm at the new residence... In the process of making this video, I discovered that by re-routing the Queen, the workers will, in her absence, return to the original colony location... how NOT to lose your valuable worker bees.
