My wife's best friend's husband, before we moved is a bee guy and has done research with the bee lab at the Univ of AZ, and the USDA (He does bees like many of us cast, probably more so). Removal or relocation first, then XXX if the queen and/or drones are aggressive, hence the hive will be as well. If you see a swarm in a tree, relax, and move on. They are all loaded and weighed down with honey and not looking for a fight, unless we are stupid enough to provoke one, they are just moving house. Unfortunately they could use a bit more patience so don't make them mad, light clothes during the day, dark a night. If find yourself in the midst of them and you feel a some of them "bump" you, time to leave ...now..... You've just been tagged/marked, hang around much longer and it is not going to well for you. Trust me, I know....
Whether we like the "Afro-bees" or not, they are stronger, hardier and far more disease resistant than their European cousins. Handling intelligently with and care will prevent most problems. Accidentally disturbing/damaging a hive, unfortunately it's SHTF, similar to rattlesnakes, and grizzly sows with cubs and skunks.
