For professional Riverwoods wildlife control, Quick Kill Exterminating Co. has been protecting this secluded Lake County village since 1990. Riverwoods is one of the most heavily wooded communities in the entire Chicago metropolitan area — approximately 3,800 residents across 3.2 square miles of mature forest, river floodplain, and wetlands. The village feels more like a forest than a suburb. The Des Plaines River runs directly through the community. Ryerson Conservation Area provides 550 acres of permanently protected woodland along the village’s border. Homes sit on large wooded lots nestled among mature trees with minimal commercial development anywhere in the village. As a result, wildlife isn’t just present in Riverwoods — it’s everywhere, all the time. Squirrels, raccoons, skunks, opossums, chipmunks, woodpeckers, and nuisance birds are a daily reality on every property.
We’re headquartered in nearby Wheeling and our technicians serve Riverwoods regularly. Whether your home is deep in the woods along the river, near the Ryerson Conservation Area, or on one of the village’s quieter residential lanes, we understand the extraordinary wildlife pressure that comes with living in one of the region’s most forested communities.
Riverwoods is fundamentally different from every other community we serve. Most suburbs have some natural areas adjacent to residential development. In Riverwoods, the forest IS the development. Homes are built within mature woodland, not next to it. Your yard doesn’t border habitat — it is habitat. Mature oaks, maples, and hickories tower over every property. Dense understory provides continuous ground cover. The forest floor surrounds your foundation on all sides. Consequently, the wildlife pressure in Riverwoods isn’t a matter of proximity to a park or preserve edge. It’s a matter of living inside the ecosystem that animals depend on.
The Des Plaines River runs directly through Riverwoods, providing a major waterway corridor that supports wildlife throughout the community. The river’s forested floodplain extends well beyond the banks, creating a wide swath of prime wildlife habitat through the village center. Raccoons forage along the river at night and den in residential structures during the day. Skunks and opossums travel the riparian corridor between properties. The river also connects Riverwoods to wildlife populations in Lincolnshire, Deerfield, and the broader Des Plaines River corridor. As a result, the village receives a constant influx of animals from the regional river network in addition to supporting its own dense local populations.
Ryerson Conservation Area borders Riverwoods with 550 acres of woodland, wetland, prairie, and river frontage. This is one of the most significant conservation areas in Lake County. The preserve supports exceptionally dense populations of raccoons, skunks, opossums, squirrels, and other wildlife that flow directly into Riverwoods’ residential areas. Because Ryerson is permanently protected, these populations will always be there. However, even without Ryerson, Riverwoods would face extreme wildlife pressure — the village’s own woodland provides more than enough habitat on its own. Ryerson simply adds another permanent layer.
Riverwoods has one of the densest tree canopies of any residential community in the Chicago area. Mature hardwoods cover virtually every property. This means squirrels have continuous aerial access to every roof in the village — not from a few overhanging branches, but from dozens of trees per property providing routes from every direction. The canopy doesn’t just connect across blocks like it does in typical suburbs. In Riverwoods, the canopy is the dominant landscape feature, and rooflines are secondary objects within it. This relationship between trees and homes makes squirrel exclusion especially critical here.
The Des Plaines River floodplain and associated wetlands extend through Riverwoods, creating low-lying, moisture-rich habitat that supports diverse wildlife populations. These areas are particularly productive for raccoon and opossum foraging. The wetland-to-upland transition zones — where low ground meets the higher residential lots — are where wildlife pressure is most intense. Animals move between the wet habitat they forage in and the residential structures they exploit for shelter.
Both eastern gray squirrels and fox squirrels thrive in Riverwoods — the village’s extreme canopy supports some of the densest squirrel populations in our service area. Every property has mature hardwoods providing aerial routes from multiple directions. Squirrels don’t just have a few branches reaching your roof — they have dozens. They chew through fascia boards, deteriorated soffits, and attic vents to enter attics. Once inside, they nest in insulation and gnaw on electrical wiring — creating serious fire hazards. Because the canopy is so dense and continuous, removing one squirrel without sealing the entry point means another takes over the same day — not within days, but within hours.
Raccoons are exceptionally common in Riverwoods. The Des Plaines River provides ideal foraging. Ryerson Conservation Area provides permanent habitat. The village’s own forest provides den sites in every direction. They’re powerful animals that tear open soffit panels, pry apart fascia, and push through deteriorated attic louvers. Inside attics, they create contaminated latrines, destroy insulation, and crush ductwork. They also den under elevated decks, in detached outbuildings, inside chimney chases, and beneath porches. In Riverwoods, raccoons may den in multiple locations across a single property — the woodpile, the shed, the deck, and the attic simultaneously. Because the surrounding habitat is so extensive, removal without exclusion is futile. New raccoons establish within days.
Skunks den beneath porches, decks, garden sheds, and elevated foundations. The village’s continuous forest floor provides unbroken ground-level travel routes across every property. They dig conical holes across lawns while foraging for grubs. In addition, spray incidents near doorways create serious odor problems. Peak denning occurs in spring when females raise kits. In Riverwoods, skunks have more denning options per property than in any other community we serve. Woodpiles, brush piles, fallen logs, and natural debris all provide additional shelter beyond the structures themselves.
Opossums shelter under porches, in garages and outbuildings, and occasionally in crawl spaces. They follow the river corridor, forest floor, and wetland edges through the village. They leave droppings, attract fleas and ticks, and sometimes die in wall voids or inaccessible spaces. Consequently, they create severe odor issues that require professional inspection to locate and resolve. In Riverwoods’ dense woodland environment, opossums may establish in multiple sheltered locations across a single property.
Eastern chipmunks burrow along foundations, under walkways, patios, retaining walls, and stone features. In Riverwoods, where properties feature natural landscaping, stone walls, wooded garden areas, and long driveways through the trees, chipmunk tunnel systems can be remarkably extensive. The tunnels undermine hardscape and direct water toward foundations. Because the surrounding woodland provides continuous habitat, chipmunk populations grow very large. The full scope of underground damage often isn’t apparent until hardscape begins to settle or shift.
Woodpeckers are highly active in Riverwoods — arguably more so than in any other community we serve. The extreme canopy, abundant natural dead wood, and forest-like environment provide ideal habitat for multiple woodpecker species. They drill into fascia boards, cedar siding, log-accent exteriors, and natural wood trim. Many Riverwoods homes feature cedar, log, or natural wood exterior elements that attract woodpeckers more than vinyl or composite siding. Furthermore, homes with carpenter bee activity are especially targeted because 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 and European starlings nest in dryer vents, bathroom exhaust vents, soffits, and building gaps. Pigeons are rare in Riverwoods due to the absence of commercial development. However, sparrows and starlings are widespread. On larger homes with complex rooflines and dormers, birds find many nesting opportunities. Their droppings damage roofing materials and painted surfaces. In addition, nesting material blocks vents — creating fire hazards and moisture problems. Furthermore, bird mites from abandoned nests migrate into living spaces. Barn swallows also nest on porches, outbuildings, and covered structures throughout the village — while protected under the MBTA, their droppings create maintenance issues.
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 Riverwoods wildlife job starts with a thorough inspection — and in Riverwoods, this inspection is more extensive than in typical suburbs. We examine the entire exterior — roofline, soffits, fascia, gable vents, roof vents, chimney caps, dormers, and every joint where gaps develop. We also inspect the foundation perimeter, porches, decks, outbuildings, and detached structures. Inside, we check attics, crawl spaces, and garages for droppings, nesting material, and entry trails. In Riverwoods’ forest environment, we also assess tree-to-roof contact points, because the extreme canopy creates more potential access routes than in any other community. We identify which trees provide direct squirrel access and which roofline sections are most vulnerable.
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 animals. Any domestic animal accidentally caught is released immediately. For attic squirrels and raccoons, we also use one-way exclusion doors. These allow animals to leave but prevent re-entry. This approach is particularly important during nesting season when young may be present. On larger Riverwoods properties, we may need multiple trap sets at different locations.
Exclusion is what separates a temporary fix from a permanent solution. Nowhere is this more true than in Riverwoods. The forest environment guarantees that new animals will test your home’s defenses every single day. We seal every identified entry point using heavy-gauge galvanized steel mesh, metal flashing, and commercial-grade materials that wildlife cannot chew, pry, or tear through. In Riverwoods, this work is typically more extensive than in other communities because the extreme canopy and forest floor provide access from every direction. We address soffits, roofline junctions, chimney chases, dormer intersections, outbuilding connections, and natural wood elements. For skunks, we install buried L-shaped barriers around porches, decks, outbuildings, and any structures with accessible voids. 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 — this is especially important in Riverwoods where raccoon infestations can be extensive. 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.
Yes. We focus exclusion on the home and immediate structures — not your entire property. Wildlife will always be active in your trees, along the river, and on the forest floor. That’s expected and unavoidable in Riverwoods. The goal is to create a sealed barrier between the wildlife outside and the interior of your home. Our exclusion materials prevent entry even though animals are testing your defenses constantly.
Timing is the best initial clue. Daytime scratching 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. In Riverwoods, squirrels and raccoons are the most common attic invaders due to the extreme canopy and forest habitat.
Reducing tree-to-roof contact does help decrease squirrel access. However, in Riverwoods’ dense canopy, it’s often impractical to eliminate all aerial routes. That’s why exclusion — sealing every entry point — is the most reliable long-term solution. It works regardless of how many trees reach your roof.
Cost depends on the species, number of entry points, extent of damage, and property size. Riverwoods homes typically require more extensive exclusion work than homes in less wooded communities due to the extreme wildlife pressure. We provide a free inspection and quote — call (847) 724-1511.
