Wasps can be assholes. They don't die if they fight back like bees do. But there are two things to keep in mind. First, when you kills wasps, they release a chemical that says to all the wasps in the area, "Hey, we have a big problem over here!" Second, they are usually around you because you have food. If you gently, slowly wave them away, kind of like a branch swaying in the wind, they don't generally feel attacked and are less likely to become aggressive. Also, if you put some food out nearby and don't bother them when they go there, they will be less inclined to bother the food on your plate.

So treat them like hungry, grumpy idiots. Don't go out of your way to piss them off, and give them a snack so they can settle down. And if they're an asshole, you might still get stung.
