Rodents love to live in attics. They enter through the vents, sleep during the day, and cause destruction at night. Their feet make it easy for them to grab limbs, branches, and electrical and telephone wires. They use this to make their nests for burrowing. They also live in woodpiles, behind trash bins, in thick grass and shrubbery, and up high in trees. If they enter your property they will leave droppings that carry diseased organisms, making it unhealthy for the residents.
