Living in the beautiful Sonoran Desert comes with its perks: stunning sunsets, iconic saguaros, and mild winters. But it also comes with a unique set of wildlife challenges, and few are as persistent or damaging as the pack rat. If you’ve heard scratching in your attic, spotted nests made of cholla cactus, or found chewed wires in your car engine, you likely have a pack rat problem.
These aren’t just nuisance animals; they are destructive pests that can cause thousands of dollars in property damage and pose serious health risks to your family and pets. While many homeowners try to tackle the issue themselves, pack rats are notoriously difficult to evict permanently without professional intervention. That’s where Arizona Pest Control comes in. As Tucson’s trusted pest management experts since 1947, we don’t just set traps—we provide comprehensive solutions to keep your home safe and rat-free.
Understanding the “Pack Rat” threat
Before you can effectively solve a pest problem, you need to understand what you’re up against. The white-throated woodrat, commonly known as the pack rat, is a native species to Southern Arizona. Unlike the common sewer rat, these creatures are actually quite cute, with large ears and fluffy tails. However, don’t let their appearance fool you.
Pack rats are hoarders by nature. They build large, complex nests—often called middens—using sticks, cactus pads, rocks, and shiny objects they find around your property. These middens are fortified fortresses that protect them from predators like owls and snakes. Unfortunately, they often choose to build these nests in pool heaters, car engines, attics, and crawl spaces.
The hidden dangers of a infestation
The damage caused by pack rats goes far beyond a messy pile of sticks. Their presence can lead to significant issues:
- Structural Damage: They are known to chew through wood, drywall, and insulation to expand their nesting areas.
- Electrical Hazards: One of the most expensive habits of pack rats is chewing through electrical wiring. This is a common cause of vehicle damage in Tucson and can even lead to house fires.
- Disease Vectors: Pack rats are hosts to kissing bugs, which can transmit Chagas disease. Their nests also attract scorpions, spiders, and fleas, bringing a secondary wave of pests closer to your home.
Why DIY removal rarely works
When homeowners first notice signs of a pack rat, the instinct is often to head to the hardware store for traps or poison. While this might catch a rat or two, it rarely solves the underlying problem.
Pack rats are territorial but also communal. If you remove one rat but leave the nest (midden) intact, a new rat will simply move into the vacant, move-in-ready home within days. Furthermore, relying solely on poison can be dangerous for the local ecosystem. Owls, hawks, and bobcats that prey on poisoned rats can suffer secondary poisoning. At Arizona Pest Control, we prioritize environmentally responsible methods that protect your property without harming the delicate desert ecosystem.
Protecting your vehicle from wiring damage
For many Tucson residents, the first sign of a pack rat is a check engine light or a car that won’t start. Pack rats seek out the warmth and security of engine compartments, especially during cooler nights. Once inside, they gnaw on wiring harnesses to sharpen their teeth and clear space for nesting.
We offer specific strategies to protect your vehicles. Beyond trapping the rats in the area, we can recommend deterrents and parking strategies that make your vehicle less attractive to these gnawing pests. If you park outside, regular inspections and our preventative services are your best insurance against a mechanic bill that could run into the thousands.

Frequently Asked Questions (FAQ)
How do I know if I have a pack rat or a regular mouse?
Pack rats are significantly larger than the common house mouse. They have large, hairless ears, big dark eyes, and a furry tail (unlike the naked tail of a roof rat or sewer rat). The most obvious sign is their nest—a large, chaotic pile of sticks, cactus, and debris, usually found at the base of a cactus, in a bush, or in a shed.
Can I just use poison bait blocks?
We generally advise against relying solely on bait blocks for pack rats, especially outdoors. Pack rats often hoard the bait rather than eating it immediately, which can lead to accidental poisoning of pets or wildlife that find the hoard. Furthermore, predators that eat poisoned rats can die. Our integrated pest management approach is safer and more effective.
How much does pack rat removal cost?
The cost varies depending on the severity of the infestation and the amount of exclusion work required (sealing up the home). However, we offer a FREE In-Home Evaluation to give you an accurate price. We also currently have a special offer of $25 off Pack Rat Control services.
Do pack rats carry diseases?
Yes. Their nests are breeding grounds for kissing bugs (which transmit Chagas disease), fleas (which can transmit plague and typhus), and ticks. Their urine and droppings can also spread Hantavirus and Salmonella. It is unsafe to clean up a large pack rat nest without proper protective gear.
Will my dog keep the pack rats away?
While dogs may catch an occasional rat, they are rarely effective at preventing an infestation. In fact, pack rats often tease dogs from the safety of a cactus nest. Worse, dogs can be injured by the cactus spines or bitten by the rats (or the snakes that live in rat nests). It is better to rely on professional pest control than your family pet.
