At least you just have them in your shutters, I have them nesting everywhere. I go out regularly every few days and do inspections all over the house (and I'm sure they're in the attics but I'm not going there until it's 30 degrees outside.

I also have these HUGE yellowjackets (I call them killer bees or just big-a_ _ bees. Does anyone know what they really are?
