Why Rodent Problems Spike in the Winter in Phoenix—and How to Stop Them

While Arizona winters are mild compared to other parts of the country, the temperatures still drop. And when temperatures plummet, rodents like rats and mice start looking for a warm place to call home.

According to the National Pest Management Association, rodent activity often increases during winter months, making early prevention essential to keeping your home safe, comfortable, and rodent-protected.

Why Rodents Invade Homes During Winter

When temperatures cool, rodents look for places that offer shelter, food, and protection from predators. Unfortunately, many Phoenix homes provide the perfect environment.

Common reasons rodents invade homes include:

• Easy access through tiny gaps, small cracks, and other entry points
• Warm areas like attics, crawl spaces, walls, and basements
• Accessible food, crumbs, pet food, and improperly stored food packaging
• Soft materials such as insulation, wood, and cardboard 

Common Signs of a Rodent Problem

Catching a rodent problem early is the key to preventing significant issues—whether it’s chewed on wiring or shredded insulation. To catch the rodent infestation before it escalates, watch for these warning signs indoors and around your property:

• Rodent droppings and urine
• Scratching or gnawing sounds in walls or ceilings
• Gnaw marks on electrical wiring, utility lines, or food containers
• Torn insulation or visible nests
• Grease marks near holes and entry points
• Unusual pet behavior from cats, dogs, or other pets

Health Risks Associated With Rodents

Beyond property damage, rodents can pose serious health risks to humans and animals. Rodents can transmit diseases, carry fleas, and spread various illnesses through contact with their droppings and urine. Exposure can lead to respiratory issues, including asthma attacks, especially in children and sensitive individuals. Keeping rodents out of your home helps protect your family’s health.

How to Prevent Rodents This Winter

The best way to get rid of rodents is to prevent them from entering. Here are proven prevention tips recommended by our pest professionals.

1. Seal Entry Points

Rodents can squeeze through extremely tiny gaps. Use steel wool, caulk, or metal flashing to seal entry points around:

• Doors and windows
• Foundations and siding
• Rooflines and vents
• Crawl spaces and attic openings

Consistently seal all visible holes and cracks to block access.

2. Eliminate Food Sources

Rodents are always searching for food. Reduce the temptation by:

• Storing food in sealed containers
• Cleaning up crumbs immediately
• Keeping pet food sealed and off the ground
• Securing trash cans and outdoor food sources

3. Remove Hiding Places

Limit outdoor and indoor hiding places by:

• Clearing clutter from attics and garages
• Trimming vegetation away from the house
• Removing debris from the ground near foundations

4. Use Traps Strategically

If rodents are already indoors, traps can help reduce populations:

• Snap traps are effective for quick removal
• Humane traps may be used when relocation is appropriate

Proper placement is key, especially near walls, nests, and known travel paths.
