Some interesting facts about bees... and their closely related cousins.
Bees like anything with a high sugar content - they'd rather steal that than go through all the work of making honey. Annoying them is the wrong thing to do, you should just put something over the top of the can so they can't smell it anymore. They'll lose interest pretty quick.
Wasps / Hornets like meat, they're mean little fuckers, they'll bite you, then sting you if you object. Worse yet, they can sting multiple times, although the pain drops dramatically after the first couple because they are out of venom.
Don't kill any of them via squashing, or crush the bodies. Crushing them gives off a scent that annoys their sisters, who will attempt to make your life painful. Essentially, they go into revenge mode when you kill some.
Bees will swarm when a hive contains 2 queens. One will gather together half the hive, they'll load up with honey to homestead with, and fly off to another home where they'll build a new nest. This is probably what you drove though. Oddly enough, despite numerous horror movies to the contrary, bee swarms are not dangerous, as a bee carrying honey will not sting. They instinctively know that stinging will kill them, thereby depriving the new hive of the life sustaining honey they are carrying. If you know anyone who keeps bees, and you see a swarm, call them, they can come collect the queen and drop her into a new hive.
