At what point do we consider our place to be mouse-free?

DB thinks we are, and that is is completely ridiculous for us to be living in the spare bedroom (which we are doing so I don’t have to wake up to the sounds of snapping.  Which I was expecting once we put out the Old Country Buffet for mice surrounded by death traps.  Which has never once happened).

At any rate, our house FEELS plugged up tighter than tight.  We’ve certainly spent enough time and money at Home Depot to confirm that feeling.  And as a side bonus, I need new shoes.
