If something scurries across your Phoenix roof at dusk, it is probably not a squirrel. Roof rats love the Valley: citrus groves, date palms, oleanders and the dense shrubs of established neighborhoods give them food, shelter and highways above ground, and the mild winters let them breed nearly all year.
Who is in your yard
Roof rats are the most frequent invader of attics and walls. They are slender climbers that follow wires, wall tops and tree branches. Pack rats, also called woodrats, are bigger and stockier, build large stick middens, and are prevalent near desert preserves and washes; they will gnaw car wiring and nest in engine bays. House mice live inside homes and sheds, and Norway rats appear in some older, irrigated parts of the metro.
What attracts them
- Citrus, dates, pomegranates and figs left on trees or ground.
- Palm fronds and overgrown oleander, which give cover and nesting sites.
- Block walls, which serve as protected travel routes between yards.
- Pet food, bird feeders and open compost.
- Pool equipment sheds and storage areas with undisturbed boxes.
Signs to catch early
Look for droppings near the base of palm trees and along attic beams, gnawed fruit with hollow shells, rub marks along block-wall caps and rafters, and dark smears at entry holes. Scratching in ceilings at night usually means roof rats; chewed hoses and wiring in a parked car points to pack rats. A dog or cat fixated on a wall can also hint at activity.
What licensed providers do
The provider typically inspects the roofline, soffits, tile or shingle edges, vents and utility openings, then the attic and garage. Sealing is critical: roof tile gaps, eave closures, dryer and swamp cooler vents, and small gaps in stucco must be closed with metal or other rodent-resistant materials. Trapping inside the attic and tamper-resistant stations outside help clear the population. In Arizona, providers also pay attention to the safe use of bait products around pets and desert wildlife.
Contaminated attic insulation may be treated, vacuumed or replaced, depending on the level of droppings and urine staining.
Rodent activity in Phoenix follows the fruit calendar and the heat. Citrus ripens through winter, which keeps roof rats fed when other food is scarce, and in the hottest summer weeks they move into cooler attics and wall voids. Neighborhoods with mature trees, such as Arcadia, Encanto and the older parts of Glendale and Mesa, tend to see more roof rat traffic than newer treeless developments, although new subdivisions beside open desert see their own share from mice and pack rats.
Desert-yard habits that help
- Pick citrus and dates regularly, and consider removing trees you do not use.
- Trim palm skirts, which give roof rats a safe home.
- Keep vegetation off walls and roofs.
- Use metal bins for pet food and seed.
- Clear woodpiles, stacked pavers and clutter from side yards.
Rodent removal in Phoenix is also a safety matter. Gnawed wiring in an attic is a fire risk, and nests in an air handler or swamp cooler can spread droppings through the house. If the sound moves from the attic to the walls, or you smell something stale in the air vents, call without waiting.

Rodent questions in Phoenix
Are roof rats dangerous to my home?
They can chew wiring and plumbing lines, and contaminate insulation. Fast action limits damage.
Why do I have rodents in a dry climate?
Irrigation, fruit trees and pools provide food and water, and houses supply shelter.
Will removing my palm trees solve it?
It helps, but sealing the structure and trapping are needed too.
Do pack rats go into houses?
They prefer sheds, garages, cars and outbuildings, but they will enter homes through gaps.
