You know, they kind of move like me in the morning in this state. I look at it this way, the more I can leave out at night to freeze, the less I have spend on bug spray next year! . Actually, an old farmer told me when I was way younger, "If you leave a pile of rotting wood out there, you will never have to worry about bugs in your house. Don't know if that one works though, but I have piles.
