In the past three days, I've killed three wasps and another was killed by a family member. *All* of them were inside. This (four dead wasps), by the way, is three more wasps than I've killed in the past five or so years. Up until now, wasps and I have been on relatively good terms - they avoid me, I avoid them. Does anyone know where on Earth these little monstrosities might be coming from? We don't have any apparent holes in our window screens or any other obvious access point. To my knowledge, none of us have seen one of the little beasts get in through an open door we were going through, either.
