Why Squirrels Enter Your Walls

Squirrels in the walls

Understanding why squirrels take up residence in your walls is the first step toward effective removal. These rodents aren’t simply lost or trapped—they’ve deliberately chosen your home for specific reasons:


Warmth & Shelter

Wall voids provide insulated protection from harsh weather conditions and predators, making them ideal winter nesting sites.


Nesting Sites

Female squirrels seek safe, secluded spaces to give birth and raise their young, with peak breeding seasons in early spring and fall.


Safety

The narrow confines of wall spaces protect squirrels from larger predators while providing easy access to food sources in your yard or neighborhood.

Important Seasonal Consideration
If you hear scratching in your walls during March-April or August-September, you may be dealing with a mother squirrel and her babies. Removing the mother without addressing the young can create additional problems with orphaned babies dying inside your walls.

Signs of Squirrels in Your Walls

Before attempting removal, confirm that the sounds you’re hearing are indeed caused by squirrels. Here are the key indicators that point to squirrel activity in your walls:

  • Distinct Noises Scurrying, scratching, and gnawing sounds, typically most active at dawn and dusk. Squirrels are diurnal, unlike nocturnal rats or mice.
  • Entry Points Visible holes or gnaw marks around the exterior of your home, especially near the roofline, soffit areas, or where utilities enter the building.
  • Nesting Materials Bits of insulation, shredded paper, leaves, or twigs found near potential entry points or in your yard.
  • Droppings Small, oblong pellets that may be visible in attics or near entry points (though often hidden inside wall voids).
  • Visual Confirmation Squirrels repeatedly entering or exiting your home at the same locations, often using the same pathways along utility lines or tree branches.
  • Step-by-Step Wall Squirrel Removal Process

    Removing squirrels from your walls requires a systematic approach to ensure all animals are safely removed and cannot return. Follow these steps for effective removal:

    1. Identify All Entry and Exit Points

    The first crucial step is locating how squirrels are getting into your walls. Without identifying and eventually sealing these openings, you’ll face an ongoing battle with reinfestation.

    Pro Tip
    Conduct your inspection at dawn or dusk when squirrels are most active. Watch for 30-60 minutes to identify exit points as squirrels leave to forage. Temporarily mark suspected entry points with brightly colored tape for easy reference.

    2. Determine If There Are Baby Squirrels Present

    Before proceeding with removal, it’s essential to determine whether you’re dealing with a mother squirrel and her babies, which requires special consideration.

    Season Likelihood of Babies What to Listen For Recommended Approach
    March-April
    (Spring breeding)
    Very High High-pitched chirping or squeaking sounds in addition to adult movement Use exclusion methods that allow mother to relocate babies
    May-July Moderate Juvenile movement sounds (less coordinated than adults) Standard removal techniques with careful monitoring
    August-September
    (Fall breeding)
    Very High Multiple movement patterns and nursing sounds Use exclusion methods that allow mother to relocate babies
    October-February Low Typically single adult movement patterns Standard removal techniques
    Never Seal Entry Points Without Confirmation
    Sealing holes while squirrels remain inside your walls will lead to animals dying in inaccessible areas, creating odor problems and attracting secondary pests like flies and beetles.

    3. Choose Your Removal Method

    Based on your situation, select the most appropriate removal strategy from these effective options:

    Option A: One-Way Exclusion Doors

    This is the most humane and often most effective method for removing squirrels from walls, especially when babies might be present.

    How to Install a One-Way Door

    • Purchase a commercial one-way door or create your own using 1/4-inch hardware cloth
    • Identify the main exit point used by squirrels
    • Secure the one-way door over this exit, ensuring it can only swing outward
    • Seal all other potential entry/exit points with hardware cloth or metal flashing
    • The squirrel will exit through the one-way door but cannot re-enter
    • Leave the door in place for at least 3-5 days to ensure all squirrels have exited
    • Listen carefully for any sounds of remaining squirrels, especially babies
    • Once activity ceases, remove the one-way door and permanently seal the opening

    Option B: Live Trapping

    If exclusion methods aren’t feasible or if you need to remove squirrels quickly, live trapping can be effective.

    Trapping Regulations
    Before trapping, check your local wildlife regulations. Many areas have specific requirements for trapping and relocating wildlife, and some jurisdictions require permits or prohibit relocation entirely.

    For effective trapping:

    1. Place live traps near identified entry/exit points or along squirrel pathways
    2. Bait traps with appealing foods such as peanut butter, nuts, or apple slices
    3. Check traps at least twice daily to prevent unnecessary stress to captured animals
    4. Relocate captured squirrels at least 5 miles away in suitable habitat (where permitted)
    5. Continue trapping until all activity in walls ceases

    Option C: Professional Wildlife Removal

    For complex infestations or if you’re uncomfortable handling wildlife, professional services offer several advantages:

    • Expertise in locating all potential entry points
    • Specialized equipment for accessing difficult areas
    • Knowledge of local wildlife laws and regulations
    • Guarantees and follow-up services
    • Comprehensive exclusion and prevention solutions

    4. Permanently Seal Entry Points

    Once all squirrels have been removed from your walls, immediately seal all entry points to prevent reinfestation.

  • Hardware Cloth Use 1/4-inch galvanized hardware cloth to cover larger openings. Secure it with screws and washers, extending at least 3 inches beyond the hole in all directions.
  • Steel Wool Pack smaller gaps and cracks with steel wool before sealing with caulk or expanding foam. Squirrels cannot chew through steel wool without injuring themselves.
  • Metal Flashing Install metal flashing around vulnerable areas like pipe entries, soffit intersections, and roof edges where squirrels commonly gain access.
  • Chimney Caps Install a quality stainless steel chimney cap with 1/4-inch mesh to prevent entry through the chimney.
  • Roof Inspection Repair any damaged shingles, vents, or roof edges that could provide access to wall voids.
  • When sealing entry points, listen carefully for any sounds that might indicate squirrels still trapped inside. If you hear activity after sealing, immediately create an exit point to prevent animals from dying inside your walls.

    Preventing Future Wall Infestations

    After successfully removing squirrels from your walls, take these preventive measures to keep them from returning:


    Landscape Management

    Trim tree branches at least 10 feet away from your roof and walls to eliminate “bridges” that squirrels use to access your home.


    Regular Inspection

    Conduct quarterly inspections of your home’s exterior, focusing on the roofline, vents, and utility entry points where damage can create new access points.


    Food Source Control

    Use squirrel-proof bird feeders, keep pet food indoors, and manage nut-producing trees on your property to reduce attractants.

    Long-Term Protection
    Consider installing a metal drip edge along your roofline, metal flashing at roof junctions, and heavy-duty vent covers as permanent deterrents against squirrel entry.

  • Multiple Entry Points When squirrels have created numerous or hard-to-reach entry points around your home.
  • Structural Damage If you discover significant damage to wiring, insulation, or structural elements inside walls.
  • Failed DIY Attempts If your removal efforts haven’t succeeded after 1-2 weeks of consistent effort.
  • Baby Squirrels When you confirm baby squirrels are present but cannot locate the nest.
  • Safety Concerns If entry points are in locations that require ladders or accessing dangerous areas.
  • Professional wildlife removal services typically cost between $300-$1,000 depending on the extent of the infestation and any necessary repairs.

    Frequently Asked Questions

    How long do squirrels typically live in walls?

    Squirrels typically don’t live in walls permanently but use them seasonally. They may occupy wall voids for 4-6 weeks during breeding seasons (spring and fall) or throughout winter in colder climates.

    Without intervention, squirrels may continue to use the same wall spaces year after year, potentially establishing a permanent presence in your home.

    Can squirrels in walls cause a fire?

    Yes, squirrels in walls pose a significant fire hazard. They frequently chew through electrical wiring, removing the protective insulation and creating conditions for electrical shorts and fires.

    According to some insurance industry estimates, rodents (including squirrels) are responsible for up to 20% of undetermined house fires in the United States.

    What damage can squirrels cause inside walls?

    Squirrels can cause extensive damage inside wall voids, including chewing electrical wiring (creating fire hazards), tearing up insulation (reducing energy efficiency), contaminating spaces with urine and feces (creating health hazards), and even gnawing on structural elements like joists and studs.

    Over time, this damage can lead to costly repairs and increased utility bills.

    Will squirrels leave walls on their own?

    Squirrels may temporarily leave wall voids to forage for food during the day, but they won’t permanently abandon a nest site without intervention, especially if they’ve established a den or have babies present.

    Even if adult squirrels leave temporarily, they will likely return as long as the entry points remain accessible.

    Is it legal to remove squirrels from my walls myself?

    Legality varies by location. In most areas, homeowners can legally remove squirrels from their own property, but specific methods may be regulated. Some jurisdictions prohibit relocation of wildlife or require permits for certain control methods.

    Contact your local wildlife agency or animal control office to understand regulations specific to your area before beginning removal efforts.

    Conclusion: Reclaiming Your Walls from Squirrels

    Removing squirrels from your walls requires patience and a systematic approach, but it’s certainly achievable with the right techniques and tools. The most successful strategy combines thorough inspection, appropriate removal methods based on the season and situation, and comprehensive exclusion work to prevent future problems.

    Remember that prevention is ultimately the most effective long-term solution. Regular home maintenance, prompt repairs of potential entry points, and landscape management will help keep squirrels where they belong—outside your home.

    By following the steps outlined in this guide, you can effectively evict unwanted squirrel tenants from your walls and restore peace and safety to your home.

    1. Forget strobe lights in the attic. It will bother them but not enough to leave. Use a rat trap with peanut butter which they find irresistible.

      Reply
    2. Use spray foam in the hole, then after expansion they will not be able to enter. cut off foam on the outside of the house and cover with sealant because the foam will break down over time and allow moisture in.

    3. Ìve dealt with squirrels chewing into my shed, one lower gap I spotted and I stuffed steel wool pads into every hole on the inside, they’ve pulled insulation out from behind the paneling for their nests, not sure if it will work or not, after just reading they only need 1.5 inches to squeeze thru, I have that size gap above the door, does anyone have any suggestions?

      • Had the same problem. Easiest solution leave a window open just a little. He’s looking for a way out too. This worked for us. We put water bottles along windowsill to let us know if he left and sure thing, the bottles were on the floor & squirrel gone. Worth a try and no cost to you.

    6. Finding pest animals in your home can be a scary and annoying thing. While it would be nice to get them out quickly it would also be great if you didn’t have to kill them either. So, I liked that you talked about calling in an animal control service to get them out.
