10 Things to Check to Rodent-Proof Your Home Before Winter:

As the weather starts getting colder here in Massachusetts, mice and rats start looking for warm places to spend the winter. Unfortunately, our homes make a pretty good place for them to settle in.

The good news is there are some simple things you can do around your house to help prevent rodents from getting inside. A little preparation now can save you a headache later.

Here are 10 things every homeowner should check before winter arrives.

 

Check Around Your Foundation

Walk around the outside of your house and look for cracks, holes, and gaps where rodents could get inside. Pay particular attention to where your foundation meets the siding.

Even small openings can give mice a way in. House mice can squeeze through gaps about the width of a pencil, so don’t overlook the smaller ones.

 

Seal Gaps Around Pipes and Wires

Pipes, electrical lines, cables, and other utilities often enter a home through openings in the foundation or exterior walls.

Check these areas carefully and seal any gaps with appropriate rodent-resistant materials. Steel wool combined with a suitable sealant may work for smaller openings, while larger gaps may require metal mesh or other durable materials.

 

Check Your Doors and Windows

Worn weatherstripping and damaged door sweeps can leave openings that rodents may use to enter your home.

Check the bottoms of exterior doors, garage doors, basement windows, and bulkhead doors. Replace worn seals and repair damaged screens where needed.

These are easy areas to overlook, especially in older New England homes.

 

Clean Up Around the Outside of Your House

Piles of leaves, stacked materials, and overgrown vegetation can provide rodents with places to hide close to your home.

Before winter, take some time to:

• Remove piles of leaves and yard debris near the foundation.
• Trim back vegetation growing close to the house.
• Move firewood away from exterior walls.
• Pick up fallen fruit and nuts.
• Clean up spilled birdseed beneath feeders.

The goal is to reduce potential hiding places and food sources immediately around your home.

 

Secure Your Trash and Outdoor Food Sources

Garbage, pet food, and birdseed can attract rodents to your property.

Make sure trash cans have tight-fitting lids, clean up spills around outdoor containers, and avoid leaving pet food outside overnight.

If you feed birds, keep the area beneath your feeder as clean as possible. A steady supply of spilled seed can attract mice and rats even when there’s no obvious food elsewhere.

 

Check Your Basement, Attic, and Garage

These areas often go overlooked during routine cleaning, making them important places to inspect before winter.

Look for droppings, gnaw marks, shredded paper, nesting materials, and gaps around pipes or other openings.

Pay attention to stored belongings, too. Cardboard boxes and piles of clutter can provide rodents with places to hide and nest. Where practical, use sturdy plastic storage containers with secure lids.

Remember that rodents don’t always enter at ground level. Openings around roof edges, soffits, and other parts of your home’s exterior can also provide access.

 

Keep Food Properly Stored

Once rodents get inside, easy access to food gives them another reason to stick around.

Keep pantry items such as cereal, flour, rice, and pasta in sealed containers. Store pet food securely, clean up crumbs, and avoid leaving dirty dishes or food scraps out overnight.

It’s also a good idea to check underneath and behind kitchen appliances when possible. Food debris can accumulate in areas that don’t get cleaned regularly.

Good housekeeping won’t guarantee that rodents stay out, but it can make your home less attractive to them.

 

Look for Signs of Rodent Activity

Even if your home looks well maintained, rodents can still find their way inside.

Some common warning signs include:

• Droppings along walls, in cabinets, or in storage areas.
• Scratching sounds coming from walls or ceilings.
• Gnaw marks on food packaging or other materials.
• Shredded paper or insulation that may be used for nesting.
• Repeated sightings of mice or rats inside the home.

Seeing one mouse doesn’t necessarily tell you how extensive a problem is. However, repeated sightings or multiple signs of activity are good reasons to investigate further.

If you find droppings, avoid sweeping or vacuuming them while dry. Follow public health guidance for safely cleaning up rodent contamination.

 

Don’t Rely on Spray Foam Alone

If you find openings around your home, make sure you seal them with materials appropriate for the size and location of the gap.

Spray foam can be useful in some applications, but rodents can chew through many common foam products. Foam alone isn’t a reliable rodent-proofing solution.

Depending on the opening, you may need metal mesh, sheet metal, mortar, or another durable material.

Also, be careful not to block vents required for proper airflow or openings that serve an essential function. If you’re unsure how to seal an area properly, consult a qualified professional.

 

Address Problems Before They Get Worse

One of the best things you can do before winter is take action as soon as you notice signs of rodent activity.

If you’re regularly seeing mice, finding droppings, or hearing scratching in your walls, simply sealing a few visible gaps may not solve the entire problem.

Effective rodent control involves identifying how rodents are getting inside, addressing the conditions attracting them, and determining whether rodents are already nesting in the building.

A professional inspection can help identify overlooked entry points and determine the best next steps for your home.

 

A Little Prevention Goes a Long Way

As temperatures drop across Massachusetts, rodents may start looking for shelter inside homes and other buildings. Taking some time to inspect your property before winter can help reduce the chances of an unwanted visitor.

No home can be guaranteed completely rodent-proof, but sealing entry points, reducing accessible food sources, and keeping an eye out for signs of activity can make a real difference.
