It's easy to tell if you have mice when they're scraping and bumping in your bedroom walls. But many mice will find other routes from the attic to the kitchen, or simply live in the pantry or kitchen wall voids since they like to be close to their food source. If you hear mice in your bedroom walls, you're one of the lucky ones. Mice are exceptionally timid and not easily detected in a home. They quietly scurry along the wall and disappear under cabinets if they hear anyone coming. The National Pest Management Association even makes the claim that if you see a mouse in your kitchen, it's a pretty good indication there are many living in your home. Over population and limited food sources make mice more desperate and willing to take greater chances.
