Rodents and fire.
Rodents cause approximately 20 percent of undetermined fires in the United States each year according to fire experts. Rodents include mice, rats, squirrels and they chew constantly because their teeth are always growing. They have incisor teeth that butt up against each other. They will chew through soft concrete, aluminum, wall boards, and pvc and lead pipes. Mice move inside in the winter months and prefer to live near the warmth of electrical components. We receive more calls as the weather becomes cooler as mice and rodents attempt to move into homes and businesses. The photo above is a good indication of how fires are started and this rodent was electrocued.
