How do the rest of you get rid of bees?

Depends what kind they are. Honey bees, don't kill them - a local beekeeper will often come and collect a swarm for free, they actually want them. Bumblebees nesting in the ground or a bird box are best left alone, the nest dies off on its own at the end of summer. If they're inside a wall cavity get someone in, because comb left inside the wall rots and attracts other pests. And make sure they're not actually wasps, that's a different job.
