Rodent Season in Arizona: Why You Hear Scratching in Your Attic

When the nights get cooler, it’s not just the weather changing—Arizona homeowners often start hearing scratching or rustling noises overhead. Those sounds usually mean one thing: rodents have moved in.

Why Rodents Invade in Winter

Rats and mice are survival experts. When outdoor food sources like seeds and vegetation decline, they move indoors looking for warmth and sustenance. Attics, garages, and walls provide insulation, food crumbs, and nesting material.

Signs of Rodent Activity

• Droppings near food or storage areas

• Chewed packaging or electrical wires

• Gnaw marks on wood

• Scratching noises at night

• Unpleasant musky odors

Ignoring these early signs can lead to large infestations within weeks.

The Risks

Rodents don’t just cause property damage—they pose health hazards. They contaminate food, trigger allergies, and can spread diseases through droppings or bites. Chewed wires also increase fire risk.

Prevention Steps

1. Seal Openings Larger Than ¼ Inch

2. Store Food in Airtight Containers

3. Eliminate Outdoor Clutter and Trim Vegetation

4. Check Garage and Dryer Vents for Gaps

5. Schedule Preventive Maintenance
