Bees, wasps, and hornets (including yellow jackets) won't sting you unless you do do something stupid -- like wave your arms and trying to swat thm out of the air or disturb their nests. as in running over a yellow jacket nest with your lawn mower. (Experience!!)
Otherwise, just go about your business of watering trees, pruning, etc. and they'll just buzz around and mind THEIR own business -- which is NOT you.
People who get stung ask for it -- one way or another.
