They can't be domesticated, and containing them after they swarm involves tricking the bees into thinking they are the ones making a decision (you can turn their hive 90 degrees after they swarm in summer and they will return in most cases, assuming they've found a new spot for a hive).
Also, mites (and foul brood) are still a pain in the ass and I can see why bees need a beekeeper to even stand a chance.
