I squirted two whole cans of squirty wasp death-foam down their wasp hole.
This did not work. I then attached my garden vacuum to the wasp hole which sucked up a lot of wasp and turned them into wasp bits.
Lastly I set fire to the wasp hole with straw and petrol.
I killed the tree that lived on the wasp hole but did not manage to kill all the wasps and had to wait for the winter to kill them instead.

may have been more effective, although much more time consuming
