What are roof rats and why are they a nuisance?
Roof rats were first discovered in east Phoenix Arcadia neighborhoods in 2002. They are not native to Arizona and may have been transported to Maricopa County from one of our neighboring coastal states. Roof rats can carry disease and are known to be destructive, gnawing through wiring and destroying citrus. They are generally active at night and during the spring months.

What can I do to prevent roof rats?
The experts advise that the most important immediate step is the removal and control of potential food sources including citrus and other fruit, pet and bird food, and garbage. They indicate that the long-term solution is the combination of a xeriscaped (low-water-use) and citrus-free yard. Residents can also work with pest control companies on prevention measures.
The city also works with neighborhood groups, such as Block Watch, to provide education and coordinate special clean ups. If you have questions, contact our Customer Contact Center at 602-262-7251or email us.
