When I was a kid we put 2l coke bottles full of sugar and chicken liver and the wasps just lobster potted inside it. Then just throw the wasps in the rubbish bin. Or we would get the electric fly swat and play cricket.
The trick is that the wasps are usually docile, it's only when you disturb the guard wasps on the nest or crush a wasp that they get agro.i never actually got stung, motherbot used to pay me a cent for every one I killed
