Humane Wildlife Removal in New Berlin, Wisconsin
Skedaddle Milwaukee — serving the greater Milwaukee area since 2017.
No traps. No poison. Permanent exclusion.
New Berlin grew out of farmland in a single generation — the town's roughly 5,300 residents in 1950 had grown to nearly 27,000 by 1970 as postwar subdivisions replaced the farms that had covered 91 percent of the township's acreage in 1930, and that low-rise, big-lot layout is still what defines the city today, with an average lot size of about 35,000 square feet in its established residential areas. Decades-old yard trees now stand tight against houses across those lots, feeding squirrels straight onto attached-garage rooflines and roof-edge trim, which is why Skedaddle Milwaukee's most common New Berlin call by a wide margin is squirrels, followed by mice, raccoons, and bats, all removed humanely with the method chosen at inspection to suit the species and the situation — controlled exit systems such as one-way doors, careful hands-on assistance, or other purpose-designed exclusion techniques — then sealed, decontaminated, and restored.

Why homeowners choose Skedaddle
A city built on former farmland, one big lot at a time
Skedaddle Milwaukee covers New Berlin as part of its greater-Milwaukee route, standing on a national company Bill Dowd founded in 1989. New Berlin was incorporated as a city in 1959 after a referendum decided by just 40 votes, turning a farm township of 1,293 residents in 1850 into a city that had reached 40,451 residents by the 2020 census across 36.44 square miles of land. That growth spread out rather than up, which is why Skedaddle has completed 20 or more humane removals here in the past twelve months, most of them squirrel calls.
How Skedaddle technicians are trained to work
Technicians train in wildlife biology, building repair, decontamination, and attic restoration. Their humane approach has approval from SPCAs and Humane Societies. Inspection determines the removal plan. Species, location, and conditions may call for a controlled exit system such as a one-way door, careful hands-on assistance, or another purpose-designed exclusion technique. After the animals have left safely, the team secures accessible entry points. Bat work follows Wisconsin DNR guidance that says not to restrict bat exits from June 1 through July 31.
What the lifetime guarantee actually covers
A sealed opening is treated as finished construction, matched to the failure point rather than patched and hoped for. The work carries our lifetime guarantee on all workmanship and materials used to seal your home for life, so if an animal comes back through something Skedaddle closed, the crew returns and closes it again at no charge. Homeowners get a written scope up front that itemizes exclusion, cleanup, and warranty coverage before anyone starts, which matters on a Greenridge or Arcadian Hills lot where the roofline runs the length of an attached two-car garage.

Wildlife we handle
Squirrels are behind more New Berlin calls than any other animal, by a wide margin, and mice, raccoons, and bats fill out the rest of the past twelve months' work. The pattern traces straight back to how the city was built: former farmland platted into unusually large single-family lots from the 1950s through the 1990s, with mature planted yard trees now standing close against the house instead of set back in a woodlot, and long attached-garage roof runs that give a climbing animal a wide, low target.
Squirrel removal
Most common call
Most squirrel calls start above the driveway. A decades-old maple or oak beside the house gives squirrels a direct route to the attached-garage roofline. Gray and fox squirrels gnaw through wood at roof-edge trim and gable returns, leaving roughly baseball-sized holes. Their January–March and May–July litters can leave dependent young overhead.
Mouse removal
Fall indoor push
Mice are the second most common call. On New Berlin's large, older lots, they usually enter low: through a settled foundation seam, where an attached-garage slab meets house framing, or at an unsealed utility penetration. The familiar clue is scratching behind a kitchen wall when cold nights send rodents indoors.
Raccoon removal
Attic denning
Raccoons rank third, drawn to deep lots along drainage corridors and wetland edges near the Root River, which rises inside the city. A female seeking a den can pull at flashing where an attached-garage roof meets the main house or work a gable louver facing a wooded backyard. Homeowners usually notice the weight overhead before seeing the animal.
Bat removal
Maternity-window planning
Bats exploit openings that squirrels or woodpeckers already made rather than chewing their own, so an inspection often finds them at a gable return or a gap along a long attached-garage roof run. Colonies stay in wall voids and attic peaks. Exclusion is scheduled outside the Wisconsin DNR maternity window, June 1 through July 31.
Other wildlife we remove in New Berlin
Beyond the four species above, a handful of other animals turn up on New Berlin's large lots. Nesting birds block dryer vents, bathroom exhausts, and chimney flues on long garage-to-house rooflines, handled through bird removal. Striped skunks den beneath decks and sheds along drainage corridors, addressed by skunk removal. Norway rats work harborage near foundations and outbuildings, covered by rat removal.
Not sure which animal you’re hearing?
Our New Berlin technicians can identify the species and confirm the entry points during a single on-site visit.
Neighborhoods we serve
What areas of New Berlin does Skedaddle service? Skedaddle Milwaukee services every residential area of New Berlin — the postwar subdivisions off National Avenue and Calhoun Road, the estate lots and cul-de-sacs on the west side around Quarry Park, the older platted blocks in Greenridge and Greenridge West, and the newer conservation subdivisions where former farmland turned into large-lot homes in the last two decades. If a New Berlin home sits inside city limits, Skedaddle services it.
What a Skedaddle inspection looks like
Booking an inspection in New Berlin ends with a written plan, not a pitch. The homeowner gets a scheduled appointment, a technician who physically walks the property, and a plain explanation of what is happening up there before anyone quotes a number.
- Book the inspection — call (414) 522-1999 or submit the online request form with your New Berlin address.
- Onsite inspection and removal plan — the technician walks the attic, roofline, foundation, and every reachable opening, documents which species is present and what it has damaged, and explains the humane plan and the pricing before any work is authorized.
- Humane removal and permanent sealing — the removal method follows what the inspection found, whether that is a controlled exit system, careful hands-on assistance, or another purpose-designed technique; damage is then repaired and the accessible openings are closed with galvanized steel mesh and weather-rated materials chosen for Wisconsin freeze-thaw cycles.
- Decontamination and attic restoration — droppings, urine-soaked material, and nesting debris are removed from wherever the animal was active inside the house and those surfaces are decontaminated; where the animal was denning in the attic, damaged insulation is removed and the attic restored to the written scope.
- Guarantee and follow-up — the job closes under the lifetime guarantee on workmanship and materials, with a follow-up visit if anything warrants a second look.
Quotes are itemized, so a New Berlin homeowner can see exclusion hardware, sealing scope, decontamination of the affected areas, and attic restoration priced as separate lines. Nothing is recommended that a technician did not physically find on the property. Call (414) 522-1999 to get on the schedule.
Skedaddle's Three-Step Wildlife Removal Process
Step 1
Assess and Remove
We begin with a detailed inspection of your home to identify the wildlife, locate active entry points, and assess the extent of the problem. Our technicians then use proven, species-appropriate methods to remove animals safely and humanely.
Learn more
Step 2
Clear and Clean
After the animals are removed, we clean and decontaminate affected areas, removing nesting materials, droppings, and other traces left behind. When needed, we also address damaged insulation and help restore the space to a clean, healthy condition.

Step 3
Prevent and Protect
Finally, we identify vulnerable areas and seal confirmed or potential entry points to help prevent wildlife from returning. Our durable exclusion work provides lasting protection and includes a lifetime warranty on the entry points we seal.
Learn moreNew Berlin wildlife by season
Activity here follows the calendar closely, driven by breeding cycles and southeastern Wisconsin's winters. Squirrels dominate year-round with two litter peaks on New Berlin's big lots, mice push indoors as overnight lows fall, birds concentrate in spring nesting, and raccoons look for attic dens late winter into spring.
| Season | Active species | Notes |
|---|---|---|
| Winter (Dec–Feb) | Mice, squirrels, raccoons | Mice fully indoors and breeding inside wall voids; first squirrel litters arrive January through March; raccoons begin claiming attic dens; heaviest attic-noise call volume of the year. |
| Spring (Mar–May) | Raccoons, birds, squirrels, mice | Peak raccoon denning with kits in attics; birds start nesting in dryer, bath, and kitchen vents plus chimney flues; first squirrel litter disperses; mouse activity drops as they move back outdoors. |
| Summer (Jun–Aug) | Squirrels, birds, raccoons, mice | Second squirrel litter May through July puts young animals on rooflines; bird fledglings leave nests and vents can finally be capped; raccoon kits mobile and noisy. |
| Fall (Sep–Nov) | Mice, squirrels, raccoons | Mice push indoors as overnight lows fall; squirrels cache food and test attics for a winter den; raccoons look for pre-winter denning space. |
Bird nesting note: Skedaddle identifies the species and waits for fledglings to leave before excluding. Native migratory birds are protected under the federal Migratory Bird Treaty Act; house sparrows, European starlings, and rock pigeons are non-native and not MBTA-protected. Chimney swifts nest inside masonry chimneys and are MBTA-protected, and the U.S. Fish & Wildlife Service advises chimney work between roughly September/October and March/April, outside the swifts' nesting and roosting season.
Quarterly focus: As of late August 2026, New Berlin is entering its heaviest stretch. Squirrels stay dominant as the summer litter disperses across mature-canopy lots and young animals test roof-edge trim and gable returns for a winter den. Mouse inspections ramp as soon as overnight lows drop and rodents push toward foundation seams. Book the inspection before the first hard cold so exclusion work is finished and sealed before any animal can settle in for winter.
Inside the Skedaddle exclusion process
01
A humane approach to wildlife removal
The premise on every job is the same: get the animal out alive, then close the way it got in. How it gets out is decided at the inspection, because species, location, and circumstances all change the right answer. A raccoon working a soffit near the Root River headwaters or a Regal Manors Park wetland corridor may be given a controlled exit system sized to it, so it leaves on its normal nightly foraging run and finds the route closed on return, while a litter found during that same inspection is more likely to need careful hands-on assistance. A squirrel colony in a Greenridge attic has all but one or two openings closed first, whatever the exit method — the Wisconsin DNR is explicit that more damage results from a squirrel gnawing its way back out of a building it was closed into. For mice it means sealing foundation seams and utility penetrations rather than baiting and hoping. Nothing gets permanently closed until the last animal is confirmed out.
02
Reuniting mothers with young whenever possible
Litter timing drives half the New Berlin calendar. Squirrel litters land January through March and again May through July, and gestation runs 38 to 45 days with three or four young typical, which means a technician on a spring roofline is very likely standing above dependent young. When a litter turns up during the inspection, the plan changes on the spot instead of proceeding. The young are hand-removed into a warmed reunion box set near the original opening, and the mother relocates them to a secondary den herself after dusk. That is both the humane outcome and the practical one — a separated mother will tear a fresh hole through the same soffit run to reach them.
03
Decontamination and attic restoration
Once the building is empty and every opening is closed, the residue comes out. In New Berlin that usually means squirrel nesting material and chewed insulation pulled out of attic bays over attached garages, mouse droppings and urine along baseboard runs and pantry corners in older ranches and Cape Cods, bird nests and debris cleared from vent penetrations and chimney flues, and raccoon latrine material removed from attic decking on lots near drainage sloughs and Root River-adjacent lots. Every affected surface is decontaminated, because the scent left behind is an advertisement to the next animal. Where wildlife was denning in the attic, damaged insulation is stripped and the attic is restored to the written scope.
04
Why every seal carries a lifetime guarantee
Materials get matched to the failure point rather than applied uniformly. Gnaw-resistant sheet metal and heavy mesh go over squirrel-worked soffit returns and gable louvers, because chicken wire will not hold an animal that chews through brick and metal. Breathable mesh goes over dryer, kitchen, and bathroom vents that still need airflow. Foundation seams and garage-slab gaps get weather-rated closure built for freeze-thaw movement. All of it carries our lifetime guarantee on all workmanship and materials used to seal your home for life, which is why homeowners on the same street with the same roofline pressure are not repeating this job every few seasons.

Frequently asked questions about New Berlin wildlife removal
How much does wildlife removal cost in New Berlin?
Cost depends on the animal, how many openings need sealing, and how much attic or garage-junction repair the job requires once the animal is out. A Skedaddle Milwaukee technician inspects the property first and hands over an itemized written quote, so nothing is priced sight-unseen. Call (414) 522-1999 to book that inspection.
Can Skedaddle remove wildlife from my New Berlin home the same day I call?
Urgent calls move to the front of the Skedaddle Milwaukee schedule, especially an animal loose inside the house or an opening that is actively being used. Whether a same-day slot is open depends on the day's route and how many New Berlin-area calls are already booked. During business hours, (414) 522-1999 reaches the office, which will book the soonest realistic appointment.
When can I schedule a bat exclusion in New Berlin?
Any time outside June 1 through July 31. The Wisconsin DNR says bat exits should stay open during that maternity window; closing them could trap flightless pups in the wall or attic. Skedaddle Milwaukee will inspect a New Berlin home and plan the exclusion at any point in the year, then carry out the physical work on the first available date once the window has passed.
What areas of New Berlin does Skedaddle service?
All of them. Skedaddle Milwaukee works the whole city, from the mid-century subdivisions off Calhoun Road and National Avenue through Greenridge, Arcadian Hills, Hearthside Acres, and the newer conservation subdivisions like Quarry Park on the city's west side. If a home sits inside New Berlin city limits, Skedaddle services it.
Does Skedaddle follow humane wildlife regulations?
Yes. Skedaddle follows the Wisconsin DNR's published guidance, which says not to restrict bat exits from June 1 through July 31 during maternity season and to make sure every animal has left before covering an opening. Bird work respects the federal Migratory Bird Treaty Act. Skedaddle's technicians use humane methods recognized by SPCAs and Humane Societies.
What wildlife is Skedaddle most likely to remove from New Berlin homes this season?
Across the past twelve months, squirrels have been the most common New Berlin call by a clear margin, with mice second, then raccoons. Bats and birds appear occasionally. Heading into fall, squirrels keep testing roof-edge trim and gable returns as young animals from the summer litter disperse and look for a winter den, while mouse calls climb as overnight temperatures drop and rodents push toward foundation seams.
Does Skedaddle offer a warranty in New Berlin?
Yes. Completed exclusion work in New Berlin carries Skedaddle's lifetime guarantee on all workmanship and materials used to seal your home for life. If an animal finds its way back through an opening Skedaddle sealed, the crew returns and re-seals it at no additional charge.
What happens to the attic after the animals are removed?
Cleanup follows the animal, not the room. Wherever wildlife was active inside the house — attic bays, a garage rafter space, a foundation void, a vent cavity — droppings, urine-soaked material, and nesting debris come out and the surfaces get decontaminated so the scent trail that draws the next animal is gone. If the animal denned in the attic, the team removes damaged insulation and restores the attic to the written scope.
Book your inspection today
A squirrel dispersing across a Greenridge or Arcadian Hills roofline will gnaw a fresh baseball-sized hole rather than give up an attic, a raccoon that has found a soffit seam near the Root River wetlands will keep returning to that same seam, and a mouse trail behind a Hearthside Acres dishwasher will keep recruiting more mice for as long as the foundation gap stays open. Skedaddle Milwaukee handles all four humanely and end to end: identify the species and every opening, remove the animals by the method the inspection calls for — a controlled exit system, careful hands-on assistance, or another purpose-designed technique — seal with materials built for Wisconsin winters, clean and decontaminate wherever they were active inside the house, restore the attic when that is where they were denning, and back the sealing work with a lifetime guarantee. Technicians work using humane methods approved by SPCAs and Humane Societies. Call (414) 522-1999 or submit an online request and a member of the Skedaddle Milwaukee team will follow up.
