For professional Highland Park wildlife control, Quick Kill Exterminating Co. has been resolving wildlife conflicts on the North Shore since 1990. Highland Park’s geography is unlike anywhere else in the Chicago suburbs — 6 miles of Lake Michigan shoreline with 100-foot bluffs, deep wooded ravines extending up to a mile inland, and a mature tree canopy that has earned Tree City USA recognition since 1980. However, the same ravines and bluffs that make Highland Park so distinctive also create some of the most intense wildlife pressure on the North Shore. Squirrels, raccoons, skunks, opossums, chipmunks, woodpeckers, and nuisance birds are active across the city year-round. As a result, wildlife conflicts here tend to be more persistent and harder to resolve without professional exclusion.
We’re headquartered in nearby Wheeling and our technicians serve Highland Park regularly — along with neighboring Highwood, Deerfield, Northbrook, and Glencoe. Because we understand the specific challenges of ravine-lot living and century-old architecture, we tailor our wildlife program to your property’s unique conditions.
Highland Park’s defining geographic feature is its network of deep, wooded ravines that cut through residential neighborhoods from the 100-foot lakefront bluffs to inland areas. Some ravines extend up to a mile from the shoreline, creating continuous corridors of dense woodland running directly through the city. These ravines serve as permanent travel routes, denning habitat, and food sources for raccoons, skunks, opossums, and squirrels. Consequently, homes built along ravine edges face wildlife pressure from a habitat corridor that delivers animals directly to their foundation, deck, or roofline with cover the entire way. Because the ravines are protected natural areas, the wildlife pressure they generate is permanent.
Highland Park’s Lake Michigan shoreline features dramatic 100-foot bluffs that are heavily wooded and largely undeveloped. These bluffs provide denning habitat for raccoons, nesting sites for woodpeckers, and shelter for skunks and opossums. Additionally, the bluff vegetation connects directly to the ravine system, which means wildlife moves freely between the lakefront and inland neighborhoods. Homes along the bluff tops — particularly in the East Highland Park and lakefront estate areas — face wildlife pressure from below as well as from adjacent ravines.
Highland Park has been recognized as a Tree City USA for over four decades, and the city’s commitment to reforestation and open space preservation means an extensive canopy of mature oaks, maples, and hardwoods covers the community. These century-old trees provide aerial highways for squirrels, nesting cavities for raccoons and woodpeckers, and habitat that connects the ravines to every residential neighborhood. As a result, even homes that don’t border a ravine directly still face wildlife pressure from the canopy overhead.
The 36-acre Ravinia Festival grounds, Moraine Park, Jens Jensen Park, Rosewood Beach, and numerous other parks add significant green space where wildlife shelters and breeds. In particular, the heavily wooded Ravinia district — originally an artists’ colony that retains much of its natural character — supports wildlife populations that push into surrounding residential areas.
The 385-acre Chicago Botanic Garden sits just south of Highland Park in Glencoe, along with the 200-acre Skokie Lagoons. Together, these natural areas create a massive band of wildlife habitat on Highland Park’s southern border. Raccoons, skunks, and opossums move north from this habitat into South Highland Park neighborhoods.
Highland Park’s housing ranges from historic colonials dating to the mid-1800s to Frank Lloyd Wright-designed landmarks to contemporary estates. Because many homes are 80 to 150 years old, they feature stone foundations, original sill plates, complex rooflines with dormers and turrets, and multiple additions over the decades. Each joint, each seam, and each deteriorated soffit or fascia board is a potential wildlife entry point. Furthermore, Lake Michigan’s humidity accelerates wood deterioration on lakefront and bluff-top homes, creating moisture-damaged materials that wildlife exploits even faster.
Eastern gray squirrels are abundant throughout Highland Park — the ravines, bluffs, and century-old tree canopy support enormous populations. They enter attics by chewing through fascia boards, deteriorated soffits, and gable vents. Because Highland Park’s mature hardwoods overhang rooflines throughout every neighborhood, squirrels have aerial access to most homes without ever touching the ground. Once inside, they nest in insulation, gnaw on electrical wiring — creating fire hazards — and cause thousands of dollars in damage. Ravine-lot homes and bluff-top properties see the heaviest activity.
Raccoons travel between the ravines, the lakefront bluffs, the Botanic Garden, and residential properties throughout Highland Park. They’re powerful animals that tear open soffit panels, pry apart fascia, rip off roof vents, and push through deteriorated attic louvers. On Highland Park’s older homes, complex rooflines with dormers, turrets, and enclosed porches give raccoons more targets to exploit than modern construction. Inside attics, they create contaminated latrines, destroy insulation, and crush ductwork. They also den under decks, in chimney chases, and beneath raised porches. Because the ravine system is permanent habitat, raccoon pressure never stops — removal without exclusion is a temporary fix.
Skunks den beneath porches, decks, stoops, and sheds throughout Highland Park. They dig conical holes across lawns while foraging for grubs — a frequent complaint in the Ravinia district and near parks. On Highland Park’s older homes, raised front porches with deteriorated lattice or open foundations are prime denning sites. Peak denning occurs in spring when females raise kits. Additionally, spray incidents near doorways and in garages are common during late-winter mating season.
Opossums shelter under decks, in garages, inside sheds, and occasionally in crawl spaces. They follow the ravine corridors and the Skokie Valley Trail through the city. They leave droppings, attract fleas and ticks, and sometimes die in wall voids or inaccessible spaces — consequently creating severe odor issues that require professional inspection to locate and resolve.
Eastern chipmunks burrow along foundations, under walkways, patios, stoops, and landscape edging. Their tunnel systems undermine hardscape and direct water toward foundations. Because Highland Park’s established properties have extensive mature landscaping, stone walkways, and decorative gardens, chipmunk damage accumulates significantly over time.
Woodpeckers are heavily active in Highland Park because the ravines and bluffs provide abundant habitat with dead and dying trees. They drill into fascia boards, cedar siding, exterior trim, and wood shingles, creating rows of holes that worsen each season as birds return to the same areas. Highland Park’s widespread use of natural wood siding and cedar on both historic and contemporary homes makes many properties particularly vulnerable. Homes with carpenter bee activity are especially targeted — woodpeckers drill into wood to reach bee larvae. We install deterrent systems and exclusion materials to protect your home. Importantly, woodpeckers are federally protected under the Migratory Bird Treaty Act, so humane deterrence is the only legal approach.
House sparrows, European starlings, and pigeons nest in dryer vents, bathroom exhaust vents, soffits, and building gaps throughout Highland Park. On older homes with decorative architectural features — corbels, eave returns, dormers, turrets — birds find nesting spots that newer construction typically doesn’t provide. Their droppings damage roofing materials and painted surfaces, and nesting material in vents creates fire hazards and moisture problems. Furthermore, bird mites from abandoned nests migrate into living spaces. Pigeons are also common around downtown Highland Park’s commercial buildings near Port Clinton Square.
Quick Kill does not provide bat removal or exclusion services. Bat work requires specialized licensing and techniques. If you suspect bats in your attic or walls, we recommend contacting a licensed bat removal specialist. However, many homeowners who think they have bats actually have squirrels or birds — call us and we’ll help identify what you’re dealing with.
Every Highland Park wildlife job starts with a thorough inspection. We examine the entire exterior — roofline, soffits, fascia, gable vents, roof vents, chimney caps, and every joint where gaps develop. We also inspect the foundation perimeter, porches, decks, and any areas where additions meet original construction. Inside, we check attics, crawl spaces, and garages for droppings, nesting material, damage, and entry trails. Because Highland Park’s housing spans from the mid-1800s to today, we adjust our inspection to the home’s era and construction — focusing on stone foundations and complex roofline features in older homes, and on roof vent and construction-seam vulnerabilities in newer homes. We pay particular attention to ravine-facing walls, bluff-side exposures, and any areas where Lake Michigan humidity has accelerated wood deterioration. We identify the species, locate all entry and exit points, and assess the full scope of activity before recommending a plan.
We place trap sets in the most effective locations based on inspection findings. A licensed technician returns each day to check traps, reinspect, and remove any non-domestic animals caught. Any domestic animal accidentally caught is released immediately. For attic squirrels and raccoons, we also use one-way exclusion doors that allow animals to leave but prevent re-entry — this is particularly important during nesting season when young may be present.
Exclusion is what separates a temporary fix from a permanent solution — and it’s absolutely essential in Highland Park, where the ravine system, lakefront bluffs, and Botanic Garden guarantee continuous wildlife pressure from every direction. We seal every identified entry point using heavy-gauge galvanized steel mesh, metal flashing, and commercial-grade construction materials that wildlife cannot chew, pry, or tear through. On Highland Park’s historic homes, this means carefully addressing stone foundation gaps, deteriorated cedar siding, aged fascia and soffits, complex roofline intersections, and the joints where multiple additions connect. For skunks, we install buried L-shaped barriers around porches, decks, and stoops. For birds, we install professional vent covers and screening.
Our exclusion work comes with a two-year warranty covering the materials, installation, and any trapping services needed in the areas we’ve sealed.
After removal, we address contamination. Raccoon latrines require careful cleanup due to roundworm risk. Squirrel-damaged insulation may need replacement. Bird nests in vents need full removal to restore airflow and eliminate mite infestations. We sanitize affected areas and remove nesting material to eliminate odors that attract new animals.
We handle wildlife conflicts across every Highland Park neighborhood. The Ravinia district — with its artists’ colony character, mature trees, and festival grounds — sees heavy squirrel, raccoon, and woodpecker activity. Braeside deals with wildlife from ravine exposure along the eastern side. East Highland Park and the lakefront estates face pressure from the 100-foot bluffs and ravine drainage. West Highland Park — properties west of the Edens Expressway — deals with wildlife from larger wooded lots. South Highland Park sees raccoons and skunks pushing north from the Botanic Garden and Skokie Lagoons. Meanwhile, downtown Highland Park near Port Clinton Square handles pigeon and bird issues around commercial buildings. Whatever the neighborhood, whatever the species — we’ve worked it before.
Timing is the best initial clue. Daytime scratching and scurrying typically indicates squirrels. Nighttime heavy thumping suggests raccoons. Light nighttime scratching could be mice (which we handle through our rodent control program). Fluttering and chirping points to birds. We confirm the species during inspection before recommending treatment.
Wildlife will always be active in Highland Park’s ravines — they’re permanent habitat that supports large animal populations. However, proper exclusion keeps animals out of your home reliably. Once we seal all entry points with wildlife-grade materials, animals cannot re-enter even though they remain active on your property. Our two-year exclusion warranty covers the work, and we recommend annual inspections to catch any new vulnerabilities as your home continues to age.
Yes. Highland Park has numerous homes on the National Register of Historic Places, including Frank Lloyd Wright designs. We match exclusion materials to the home’s exterior — flashing color, mesh placement, and installation methods that preserve the home’s appearance while providing wildlife-proof protection. We have extensive experience working with the complex construction details of Highland Park’s older architecture.
Yes. Because woodpeckers are federally protected, we use deterrent systems and exclusion materials rather than lethal methods. We also address underlying attractants — if carpenter bees are drawing woodpeckers to your home, we treat the bee galleries first to remove the food source.
Cost depends on the species, number of entry points, extent of damage, and cleanup needed. Highland Park’s older, larger homes with complex rooflines typically require more extensive exclusion work. We provide a free inspection and quote — call (847) 724-1511.
