What happens is that from a very tall palm tree, once a nest of those wasps fell on a pile of leaves and branches, I quickly grabbed it, placed it on a tile of a planter and ran away. The wasps stayed there for a time, and as I was always approaching them, I learned that they can be handled with very slow movements. Eventually they all went away and left the nest empty.
Damned. What a patience! I would have get mad before that.
