There is a mouse in my house , which I guess is better than ants in my pants. I'm almost positive it is making a home in a bucket in our pantry that we fill with our plastic and paper bags. It makes a lot of ruckus and is always squeaking. I never hear a reply squeak so I'm guessing it is alone... I hope. In order to make my self feel better I keep having found thoughts of ratatouille and Stewart Little. I also imagine him racing around the house on a tiny razor scooter, collecting buttons and pieces of thread for his humble little home in our pantry. This really helps, I suggest using it if you hear a squeaking in the night.
