Unfortunately it often happens in the middle of summer, usually in a barn or an outbuilding of some sort, and if that building is close to habitations, then the fire brigade has to be called. You can imagine the danger of having a whole nest of these huge insects next to, or even in, your garden!
Me, I can't help it - when I see one I tende to run a mile, except if one gets inside the house, and then it's war!
