From Attics to Basements: Where Rodents Hide in Your Home

Rodents Are Masters of Hiding

If you think rodents only live in your walls, think again. Mice and rats are remarkably adaptable and can make nests almost anywhere in your home. They are skilled climbers, jumpers, and even swimmers, allowing them to access areas most homeowners would never suspect. Knowing where to look—and understanding what attracts them—is key to early detection and effective control.

Rodents are motivated by three things: food, water, and shelter. Once they find an entry point, they quickly seek out warm, quiet, and undisturbed spaces to build nests and reproduce. Because they are nocturnal, most activity happens at night, which means homeowners often don’t notice them until the signs become obvious.

Attics: Warm, Quiet, and Full of Nesting Materials

Your attic is a prime hiding place for rodents, especially during colder months. The warmth, insulation, and lack of foot traffic make it a perfect environment for building nests. Mice and rats often enter through roof vents, gaps around soffits, or openings where utility lines enter the house.

Warning signs in the attic include:

• Droppings along wooden beams or insulation
• Shredded paper, insulation, or fabric used for nesting
• Gnawed wires or chewed wood
• Scratching or scampering noises, especially at night

Rodents in the attic can cause major problems over time. Chewing on wiring can create fire hazards, and their droppings can contaminate insulation. If you store holiday decorations or keepsakes upstairs, rodents can damage cardboard boxes and fabrics while spreading bacteria.

Regularly inspecting your attic—especially in fall and winter—can help you catch these issues early. Homeowners should also check for light leaks from the attic floor, which often indicate small gaps that rodents can use to move between levels of the home.

Basements and Crawl Spaces: Hidden Highways Beneath Your Home

Dark, damp, and quiet—basements and crawl spaces are another favorite hideout for rodents. These areas often serve as “highways” that allow mice and rats to travel between rooms. They can move easily through ductwork, pipes, or foundation gaps to reach kitchens and living spaces.

Because these areas are often used for storage, boxes and clutter provide perfect nesting spots. Cardboard, in particular, attracts rodents because it’s easy to chew and shred for nesting material.

What to look for in basements and crawl spaces:

• Droppings or gnaw marks near stored boxes
• Chewed insulation or wiring
• Small holes around pipes or foundation walls
• Musky odors or greasy rub marks along walls

Keeping these areas clean, dry, and well-lit can discourage rodent activity. Sealing cracks around foundation walls and utility openings with steel wool and caulk is one of the most effective ways to prevent access. Installing door sweeps and repairing damaged vents also limits entry opportunities.

Kitchens and Pantries: The Heart of the Home—and the Main Attraction

When it comes to food, rodents are opportunists. Your kitchen and pantry are irresistible to them, especially when food is left out or stored in unsealed containers. Mice can survive on surprisingly small amounts of food each day, and a single crumb trail can be enough to sustain them.

Rodents often enter kitchens through gaps under appliances, holes around plumbing under sinks, or spaces behind cabinets. Once inside, they’ll chew through packaging to reach dry goods like cereal, rice, and pet food.

To reduce the risk of infestation:

• Store dry food in airtight containers made of glass or thick plastic
• Wipe down counters and sweep floors regularly
• Empty trash frequently and keep lids sealed
• Clean behind and under large appliances where crumbs accumulate
• Keep pet food stored securely and avoid leaving bowls out overnight

Rodent infestations in kitchens are particularly concerning because of the contamination risk. Even a small number of droppings can spread harmful bacteria such as Salmonella or Leptospirosis, putting your family’s health at risk.

Garages and Utility Rooms: The Perfect Entry Points

Garages are one of the most common gateways for rodents to enter a home. Because garage doors are frequently opened and closed, and because weather stripping wears down over time, these areas offer easy access. Once inside, rodents can move into walls, ceilings, and connected rooms through cracks or ductwork.

Utility rooms and laundry areas also attract rodents because of the warmth generated by appliances and the availability of nesting materials like lint, cardboard, and fabric.

Signs of rodent activity in these spaces include:

• Chewed storage boxes or bags
• Droppings along baseboards or near water heaters
• Gnawed electrical cords
• Shredded materials or insulation

To make your garage less inviting, seal all exterior openings, replace worn door seals, and keep stored items off the floor. Avoid stacking clutter along walls and store materials in plastic bins with tight lids.

Additional Hiding Spots You Might Overlook

Rodents can also hide in several unexpected places that many homeowners overlook, such as:

• Behind refrigerators or dishwashers, where warmth and crumbs collect
• Inside furniture, such as couches or recliners that are rarely used
• Within wall voids or dropped ceilings in basements or finished attics
• Under decks or porches, where they can find shelter and easy access to the home’s foundation

The key to detection is staying alert for subtle clues—sounds, droppings, chew marks, or unusual odors—that might indicate rodent activity even if you don’t see them directly.

Protecting Your Home Year-Round
