Roof rats feature large ears, scaly tails, and dark brown or black coloring. The name “roof rat” originates from their preference for living at an elevated height, usually in attics, roofs, or trees. And although they are primarily active during the winter and early spring, these pests live year-round.
While they are not native to Arizona, they have been multiplying in huge numbers and spreading across the valley. Likely brought in by a traveller from another state, roof rat infestations have greatly increased since their discovery in 2002. The best method to keep roof rats away is to make your home inhospitable for them!
