We live in the foothills where rodents and other animals are always trying to come into the house for food, warmth and water. We always had a mouse problem until we hired Enviropest. They found the mouse "highways," and we blocked them. They also put out a bait that kills the mice but doesn't harm the environment or dogs or cats that might be around. Every three months, they come to the house on a maintenance run, and our home has been mouse-free since we started hiring them. They are a very good company.
