How Do You Get Rid of Squirrels in the Attic in New Berlin, WI?

Squirrels might look harmless as they dart through the trees in Malone Park or scurry across the lawns in Weatherstone, but once they find their way into your attic, they become a noisy, destructive headache.

Homeowners in New Berlin, WI, especially those living near wooded pockets like Calhoun Park Estates or along tree-lined streets in Regal Manors, know that these agile climbers can chew through roof vents, insulation, and even wiring—causing costly damage. And with Wisconsin’s long, cold winters, it’s no surprise that squirrels often seek warmth and shelter in attics around the greater Milwaukee area.

If you’ve been hearing scratching in your ceiling or spotting nests near your roofline, chances are you’re dealing with a squirrel problem. The older architecture in parts of New Berlin and nearby communities like Brookfield and West Allis—with their charming gables, cedar shakes, and vintage attic spaces—often provide easy access points that squirrels love to exploit.

That’s where AAAC Wildlife Removal of Milwaukee comes in. With expert knowledge of local neighborhoods and humane, effective squirrel removal methods, they’re your go-to solution for reclaiming your attic before further damage sets in.

Why Squirrels Invade Attics in New Berlin, WI

New Berlin is packed with mature trees, sprawling parks, and residential areas that border natural habitats—prime conditions for squirrels to thrive. Neighborhoods like Carriage Hills and Gatewood, with homes nestled near wooded trails and green corridors, often see increased squirrel activity, especially as fall turns to winter.

Squirrels instinctively seek shelter when temperatures drop, and attics offer the warmth, dryness, and safety they need to build nests and survive the season.

Beyond climate, the structure of many New Berlin homes also plays a role. Houses with gabled roofs, dormers, and wood trim—common in areas like Weatherstone Village and Lindfield Estates—can develop small gaps or weaknesses over time.

These spots become entry points for squirrels, especially if nearby trees provide a natural bridge from branch to roof. Add to that the city’s proximity to lush areas like Minooka Park and the Root River Parkway, and you’ve got a perfect storm for attic invasions.

Unique Challenges of Squirrel Removal in New Berlin, WI

Cold Winters Drive Squirrels Indoors

New Berlin winters can be brutal, with snow and freezing temps that drive wildlife to seek warmth wherever they can find it. Squirrels often pick attic spaces as a cozy retreat, especially in neighborhoods near wooded areas like Minooka Park and Calhoun Park. This seasonal behavior increases squirrel intrusions during late fall and winter months.

Older Homes with Complex Architecture

Many homes in New Berlin and nearby cities like West Allis and Brookfield were built with charming but intricate rooflines—gables, dormers, and decorative wood trim that squirrels love to exploit. Entry points often go unnoticed in these structures, especially in historic properties around Elm Grove or Weatherstone Village, where wear and tear adds to the vulnerability.

Abundant Tree Cover Near Residential Rooflines

Neighborhoods like Gatewood, Regal Manors, and Lindfield Estates have an abundance of tall oaks, maples, and evergreens lining their streets. These trees give squirrels a natural highway straight to rooftops, making attic access all too easy. Even well-maintained homes in these areas can become targets without preventative trimming or exclusion work.

Difficult Access and Hidden Nesting Spots

Squirrels don’t just settle in easy-to-spot corners—they burrow deep into insulation, settle behind beams, or wedge between ductwork. In larger homes near the Fox River Parkway or along Greenfield Avenue, attic spaces can be complex and cluttered, making it hard to spot or reach all nesting areas without professional help.

Signs of a Squirrel Infestation in Your Attic

Noises in the Ceiling or Walls

If you’re hearing fast-paced scratching, rustling, or thumping sounds early in the morning or late in the afternoon—especially in areas like Regal Manors or near Calhoun Park—you’re likely dealing with a squirrel infestation. These sounds are usually most noticeable in ceilings, walls, or above light fixtures and often follow a predictable routine tied to the squirrel’s daily movements.

Chewed Entry Points and Structural Damage

Squirrels are persistent chewers. In neighborhoods like Weatherstone and Greenfield Park, homeowners frequently report gnaw marks on roof edges, fascia boards, and attic vents. Their strong teeth can even damage gable vents and wooden trim, giving them repeated access to your attic and increasing your risk for long-term structural issues.

Droppings and Nesting Debris

Attics in older homes throughout West Allis and Brookfield are especially vulnerable to contamination from squirrel nests. You might find piles of shredded insulation, twigs, leaves, or even food stashes like acorns and pinecones. Their droppings, about the size of a grain of rice, can accumulate quickly and pose a biohazard over time.

Chewed Wires and Strange Odors

In neighborhoods with historic homes like Elm Grove, chewed electrical wires are a common and dangerous side effect of squirrel infestations. This damage poses a fire risk and often accompanies a musky odor from droppings or urine. The longer squirrels stay in your attic, the worse the smell and potential damage will get.

Grease Marks and Fur Along Entry Points

Squirrels often leave behind greasy smudges or tufts of fur where they squeeze through attic vents, soffits, or broken eaves. These dark rub marks are especially noticeable on light-colored wood or siding, common in homes throughout Carriage Hills and Lindfield Estates.

Increased Squirrel Activity Around Your Roofline

If you frequently spot squirrels pacing your roof, chewing near your gutters, or vanishing near a chimney or attic vent, it’s a major red flag. This behavior is often observed in homes backing up to wooded spaces like Minooka Park or along Greenfield Avenue.

Unusual Pet Behavior Indoors

Pets often detect attic invaders before their humans do. If your dog or cat is fixated on the ceiling, growling, or pacing near attic access points, it could be reacting to sounds or scents coming from above—especially in quiet, residential areas like Gatewood or Weatherstone Village.

Risks of Having Squirrels in Your Attic

Fire Hazards from Chewed Wiring– Squirrels have strong teeth that never stop growing, which drives them to gnaw constantly—including on your home’s electrical wiring. This is especially dangerous in older homes around Elm Grove or West Allis where original wiring may already be fragile. Exposed wires can spark fires, putting your home and family at serious risk.

Contamination from Droppings and Urine– Squirrel droppings may seem minor at first, but over time they build up and soak into insulation, wood, and sheetrock. The result is a lingering odor and the potential spread of harmful bacteria. This is especially common in attic spaces that aren’t accessed often, like those found in larger homes in Brookfield and New Berlin’s Weatherstone neighborhood.

Damage to Insulation and Structural Materials– Nesting squirrels shred fiberglass insulation and wooden rafters to create cozy dens. In areas near Malone Park or Calhoun Road, homeowners often discover significant energy loss and rising heating bills after a squirrel infestation. Over time, this damage weakens attic structures and drives up repair costs.

Attraction of Additional Pests– Left unchecked, squirrel nests can attract other wildlife like raccoons, insects, and even mold growth. This cascade of issues is common in homes near wooded areas like Minooka Park or the Root River Parkway. Once one pest moves in, it often signals to others that your attic is fair game.

How to Get Rid of Squirrels in Your Attic

Squirrel Trapping

Professional squirrel trapping is the first step toward solving the problem. In neighborhoods like Regal Manors or Carriage Hills, where squirrels are active year-round, licensed wildlife technicians use humane traps to safely remove the animals. These traps are strategically placed near entry points and nesting areas to ensure the fastest, most effective capture without harming the squirrels.

Exclusion Techniques

Once the squirrels are out, keeping them out is just as important. Wildlife pros seal off all current and potential entry points—like roof vents, soffits, gable edges, and gaps near chimneys. Homes near tall trees in areas like Gatewood or along Greenfield Avenue often require roofline reinforcements and one-way exclusion doors that let squirrels exit but not return.

Damage Repair

After removal, any chewed wood, torn insulation, or exposed wires need to be addressed right away. Attic damage is especially common in older homes in Brookfield or West Allis, where time and weather have already worn down structural elements. Wildlife professionals can patch holes, replace insulation, and repair soffits to restore your home’s integrity.

Attic Cleanup and Sanitization

Squirrel nests and waste carry odors, parasites, and harmful bacteria. A full attic cleanup includes removing contaminated insulation, deodorizing the space, and applying disinfectants to prevent mold or disease. This service is vital in homes near Minooka Park or Weatherstone Village, where repeat infestations are more likely due to dense vegetation and close tree cover.

Why Professional Squirrel Removal Is Essential

Removing squirrels from your attic isn’t as simple as setting a trap and calling it a day—especially in Wisconsin, where wildlife laws regulate how and when animals can be captured and relocated. DIY attempts often lead to missed entry points, damaged insulation, or worse—illegal removal practices. In older homes throughout Brookfield, West Allis, and the tree-heavy streets of New Berlin’s Lindfield Estates, squirrels often exploit hidden gaps and weak rooflines that untrained eyes might miss. Without professional exclusion, even one missed access point can lead to repeat infestations that are harder and costlier to fix the second time around.

Additional Tips for Preventing Squirrel Infestations

Trim Back Overhanging Branches– Squirrels often use trees as a launching pad to get to your roof. If you live in neighborhoods like Gatewood or Lindfield Estates—where large oaks and maples are common—it’s essential to keep branches at least 6–8 feet away from the roofline. This simple step cuts off their easiest access point.

Seal Vents, Soffits, and Gaps– Squirrels can squeeze through openings as small as 2 inches. Install vent guards, reinforce soffits, and check for cracks near gables or dormers. Homes near wooded parks like Minooka or Calhoun often benefit from metal flashing in weak spots to keep persistent squirrels out.

Install Chimney Caps and Roof Vent Covers– Chimneys and attic vents are open invitations to curious wildlife. If your home is near wooded corridors like Fox River Parkway or Greenfield Park, having a chimney cap and vent cover isn’t just a nice-to-have—it’s essential. These barriers help prevent not only squirrels, but other critters like birds and raccoons from moving in.

Schedule Regular Attic Inspections– Most homeowners never go into their attics—until something’s wrong. Preventative inspections, especially before winter, help catch signs of nesting early. This is particularly helpful in older New Berlin homes with dated insulation or previous wildlife activity.
