Mice, rats and other rodents have been known to cause fires in homes by chewing wires. They are able to enter your home through a crack the size of a dime. They are able to jump and swim long distances and can climb any type of surface. Rodents are also known to carry fleas and ticks. To keep rodents from making your home theirs, keep all food, pet food, trash, bird seed, etc. cleaned up. Keep vegetation low and remove any debris from your property such as limbs, wood piles, old cars, etc. as these are harborage sites for rodents.
