They tend to only fly short distance from their nest (say 50 m ish). Try to bee line them back to the nest and pour petrol into it. No don't light it!!
Even if it's not your property your neighbours may be keen for you to destroy them anyway. I've got to beeline some at home this week, their getting into the honey she'd. They can fit into gaps that bees can't.
Easy to sneak up behind a wasp and squash it. They move slow when it's cold too. Give it a good squeeze before it turns around on your finger, but I'm sure you'll figure that out yourself pretty quickly. Enjoy. I'll let you know if I find my nest. Good luck.
