You've heard of the idea of building a better mousetrap, right? Well, sometimes trapping these small creatures isn't humane, so why not repel them from your home? In lieu of poison, try to figure out where mice might be making entry into your home. Make a bundle of loose animal fur (from a cat or dog) mixed with dried mint. The combination of the two scents is a natural deterrent and may help prevent them from roosting in your home.
