Could this be temperament also? It seems more applicable to a wasp than personality, although I have to confess I stay two or three feet away from them when I can, in order NOT to get personally acquainted.
We've had very good success against them with a Shop Vac. The worse infestation was in out greenhouse. We leave the doors open in summer. They'd made a giant nest under a growbed up inside the cinder blocks that were used as "legs".
