Why Your Garage Becomes a Pest Hotel in Winter (and How to Stop It)

As winter sets in across the White Mountains, most Arizona homeowners think they’re safe from pest problems — after all, cold weather should drive insects and rodents away, right? Not exactly. When temperatures drop, pests don’t disappear; they move inside, and one of their favorite hideouts is your garage.

From rodents and spiders to crickets and roaches, your garage offers the perfect mix of warmth, shelter, and food sources. Without regular prevention, it can quickly turn into a pest hotel — full occupancy, no vacancy.

Here’s why your garage becomes a pest haven during winter in the White Mountains — and how Neff Exterminating can help you kick out unwanted guests for good.

1. Garages Offer Warmth and Shelter

While Snowflake and Show Low don’t experience the freezing winters seen elsewhere, the nighttime temperatures are cold enough to send pests indoors. Your garage traps warmth from vehicles, water heaters, and connected living spaces, making it the ideal spot for pests to survive the season.

Common winter invaders include:

• Rodents (mice, pack rats, and roof rats) – They nest in insulation, storage boxes, or engine compartments.
• Spiders – Especially black widows and brown recluses, which love quiet corners and dark crevices.
• Crickets and roaches – Drawn to moisture and dark spaces near water heaters or drains.
• Scorpions – Found under stored items or near baseboards where they can hide unnoticed.

Once they establish shelter in your garage, it’s only a matter of time before they venture deeper into your home.

2. Easy Access Points Let Pests Walk Right In

Your garage is one of the easiest entry points for pests to infiltrate. Gaps under doors, cracks in concrete, and unsealed vents act as open invitations. Even the weatherstripping around garage doors deteriorates over time, leaving gaps large enough for rodents or insects to squeeze through.

Pro tip: A mouse only needs a quarter-inch gap to get inside — that’s smaller than a dime. Once they find a way in, they often create tunnels and chew through insulation or stored materials to nest comfortably.

How to stop them: Seal entry points with caulk, install new weatherstripping, and inspect door sweeps for wear. A professional rodent inspection from Neff Exterminating can identify and close hidden gaps you might miss.

3. Stored Items Create the Perfect Nesting Spots

Most garages double as storage units — filled with boxes, holiday decorations, camping gear, and yard tools. While convenient for you, this clutter provides endless hiding spots for pests.

Mice love nesting in cardboard boxes and insulation, while spiders spin webs behind seldom-used items. The less you disturb these areas, the more appealing they become for pests looking to settle in for the season.

How to stop them:

• Store items in sealed plastic bins instead of cardboard boxes.
• Keep items elevated off the floor whenever possible.
• Organize and declutter at least twice a year — especially before winter.

Reducing clutter limits shelter options for pests and makes it easier to spot early signs of infestation.

4. Food and Trash Attract Unwanted Guests

Even a small amount of food or waste can draw pests inside. Pet food bags, bird seed, and garbage cans are some of the biggest culprits. Once rodents or insects find an easy meal, they’ll keep coming back — and bring friends.

How to stop them:

• Store pet food and bird seed in airtight metal or heavy-duty plastic containers.
• Empty trash regularly and use bins with tight-fitting lids.
• Clean up spills, crumbs, or oil drips immediately.

By removing easy food sources, you make your garage far less appealing to hungry intruders.

5. Moisture Draws Insects and Rodents

Garages often trap moisture from snowmelt, leaky pipes, or unsealed foundations. Damp areas attract crickets, roaches, and rodents looking for a drink or a nesting spot.

How to stop them: Check for leaks around your water heater and utility lines. Use a dehumidifier if moisture builds up during the winter months. For properties with vegetation growing too close to the home, consider weed control services to remove damp hiding places near your foundation.

6. Termites Can Use Your Garage as a Gateway

Garages often sit on unprotected slabs, which makes them vulnerable to subterranean termites. These destructive pests can enter through expansion joints, cracks, or untreated wood stored directly on the concrete. Once inside, they can spread to other areas of the home.

How to stop them: Keep wooden materials elevated and dry. Avoid storing firewood against garage walls. Schedule a winter inspection with Neff’s termite control specialists to ensure your property stays protected year-round.

7. How to Pest-Proof Your Garage This Winter

Taking a few proactive steps now can keep your garage — and your home — pest-free all winter long:

• Inspect doors and weatherstripping: Replace damaged seals or rubber bottoms on garage doors.
• Seal foundation cracks: Use silicone caulk or concrete patch to close small openings.
• Eliminate clutter: The fewer hiding spots, the better.
• Control weeds and debris: Keep vegetation trimmed and remove debris that shelters pests near entry points.
• Schedule a professional inspection: Early detection prevents infestations from spreading.

A winter service plan from Neff Exterminating provides year-round coverage, ensuring your home and garage remain protected no matter the season.

8. Why Winter Pest Control Still Matters in Arizona

Even though Arizona’s winters are relatively mild, pests in the White Mountains don’t take a break. Rodents breed year-round, termites stay active underground, and spiders seek shelter in any available space. Skipping winter service only gives pests a head start when spring arrives.

That’s why our winter pest control program focuses on prevention — not just reaction. By inspecting, sealing, and treating key areas like garages, attics, and foundations, we stop problems before they start.
