What is the best time to catch a swarm of bees?

Swarms typically occur at 10 or 11 o'clock in the morning when they will often settle as a cluster, hanging off a branch. This is the best time to catch them. While hanging there, they will be looking around for a more permanent home and will fly off when they find one. They may remain there for a day or two or they may disappear after an hour so it is better not to delay.
