I'm wondering if maybe those bugs flew out of my attic. Although I really don't have much of an attic. The upstairs part of my house has sloping walls, dormers and gables. The only part I would call an attic is the little cubby hole cupboards built into the bottom part of the walls.
I don't know. If they did fly out of there, they won't survive for very long. It's too cold. I kind of feel sorry for them now.
