This afternoon I found one in our den, quickly rushed the children out, and slammed the door. Chris went in right away and killed it with a broom--one of the perks of having a husband who works from home.
Not two hours later, I was reading a book to John in the den when I heard wings flapping (yes, the wings were that big!). I glanced around the room in some panic and saw a second wasp! We rushed out and slammed the door, this time Chris to return after the kids' bed time to kill it.
While he was doing that hit job, wasps 3 and 4 emerged and met their ends. We surmised they were probably coming from the unused chimney, so we opened up the glass doors to have wasps 5 and 6 appear.
Chris killed all six wasps with a broom, sprayed wasp poison up the chimney, sealed the chimney's glass doors with packing tape, and I guess we'll be calling the exterminator tomorrow. It's almost looking like we might as well establish a contract with this nice pest control man, we call him so often!
