A community on the edge of 15,000 acres of marsh
Navarino is defined by what surrounds it. The community sits in southern Shawano County against the Navarino Wildlife Area — over 15,000 acres of state land spreading across southern Shawano and northeastern Waupaca counties, about seven miles south of the city of Shawano. This isn’t a tidy park. It’s a working mosaic of sedge meadow, emergent marsh, floodplain forest, bottomland hardwoods, bog, aspen and oak woods, pine plantation, and sandy upland ridges, cut through by the Wolf River and the West Branch of the Shioc River. People come here to hunt, fish, trap, canoe, and bird, and the Navarino Nature Center runs trails and programs along the edge.
That’s a wonderful place to live next to. It’s also, from a pest and wildlife standpoint, one of the most demanding environments in the region — and it’s exactly why BugBoss The X-Terminator does both pest control and wildlife removal under one roof. We’re based just south in Clintonville at 600 S. Main St., a short drive from the marsh edge. When you live on the boundary of a 15,000-acre wetland and wildlife corridor, the animals aren’t a rare event; they’re a constant flow past your buildings. Every open soffit, torn vent, uncapped chimney, and unsealed sill plate gets found — and found fast. Understanding the corridor, and building the structure to keep it out, is the whole game here.
The wetland-edge pest and wildlife calendar
Spring (March–May): denning season on the corridor
Spring is when the corridor’s mammals go looking for places to raise young, and structures near the marsh are prime real estate. Raccoons — females especially — pry into chimneys and torn soffits to den. Squirrels chew into attics at weak roof edges. Skunks move under decks, porches, and outbuildings. This is the highest-pressure wildlife season of the year around Navarino, and catching an animal before it has a litter inside your attic makes the whole job simpler and cleaner.
Spring also stirs the overwintering pests. Mice that spent the winter in the walls get active and breed, and the cluster flies and boxelder bugs that overwintered in the wall voids crawl toward the windows on warm days. And as the ground thaws, the marsh begins its long mosquito season, with the first broods emerging from standing water as soon as it warms.
Summer (June–August): the mosquito season and the bat window
Nothing shapes summer in Navarino like the mosquitoes. You live beside thousands of acres of sedge meadow, marsh, and river bottomland — the single best mosquito habitat in the county — and there’s no eliminating that. What a seasonal mosquito program does is realistic and worthwhile: it knocks back the adults resting in your yard’s shaded vegetation and treats the standing water you actually control, so the yard is usable for an evening on the deck or a summer gathering. Around the buildings, wasps and hornets reach their largest, most defensive size by August, driving most of the season’s wasp and hornet calls.
Summer is also the one stretch when bats cannot be sealed out. The Wolf River corridor is excellent bat habitat, and we find plenty of roosts in Navarino attics and outbuildings. But Wisconsin protects its bats, and the DNR requires that exits stay open June 1 through July 31 while flightless pups are present. If you find a colony in July, the right move is to plan the exclusion for August or later — never to seal the building and trap pups inside. The bats page and the Wisconsin bat exclusion law guide lay out the timing.
Fall (September–October): the rodent push and a second wildlife wave
Fall brings two pressures at once. As the nights cool, mice and deer mice move off the sandy uplands, field edges, and marsh margins toward warm structures, and any building near the corridor is a target. At the same time the fall invaders — cluster flies, boxelder bugs, and Asian lady beetles — mass on sunny south and west walls and work into gaps to overwinter. Cluster flies are common here because their larvae parasitize earthworms in the surrounding soil, so it’s the habitat, not the housekeeping, that produces them.
Fall is also a second wildlife peak, as animals that summered in the marsh look for winter shelter and test your buildings. Everything you seal and treat before the freeze — rodent entry points, wall-void gaps, soffit and roof-edge weaknesses — pays off across the entire winter. It’s the highest-value time of year to get ahead of the corridor.
Winter (November–February): what wintered in
By winter the outdoor traffic slows, and what got in during fall is what you’re living with. Mice that found a warm nest breed year-round indoors, so a few in November become an infestation by February if the gaps stay open. A thawing January afternoon warms the wall voids enough to rouse the overwintering cluster flies and lady beetles, which turn up again at the sunny windows. Deer mice in a cabin, garage, or seldom-used room are a hantavirus concern, so winter cleanup should be done damp and careful. And a raccoon or squirrel that got into an attic in fall will happily overwinter there. Winter work in Navarino is rodent exclusion, fall-invader cleanup, and dealing with any wildlife already denned in.
Building science on the wetland edge
Living beside the corridor means your structure is under constant test, so the building details matter more here than in a sheltered village lot.
Older farmhouses and lake-and-river cabins around Navarino often sit on fieldstone or block foundations with unsealed sill plates, and many older ones are balloon-framed — meaning the wall cavities run straight from the crawlspace to the attic, an open route for a mouse that enters at the sill or a bat that slips behind fascia. Seasonal cabins add a wrinkle: they sit empty and undisturbed for long stretches, which is precisely when rodents move in and settle.
Soffits, fascia, and roof edges are the wildlife-entry front line here. In a high-traffic corridor, a lifted soffit return or a gap at a fascia board is an open invitation to bats and squirrels, and an uncapped chimney is a raccoon den waiting to happen. Decks, porches, and outbuildings with open skirting are where skunks and raccoons den underneath. And crawlspaces and damp basements near the water table invite carpenter ants and springtails, and give rodents a cool, quiet harborage.
We inspect all of it and treat the structure as the actual solution — because on a wetland edge, no amount of spraying substitutes for closing the building.
Ecology: why the corridor drives everything
The whole point of Navarino is the habitat, and every habitat type around you drives a specific pest. The marsh and river bottomlands are a mosquito engine and hold the standing water broods need. The sedge meadow and grassy edges are where blacklegged ticks wait, sustained by the corridor’s abundant deer and small mammals — which makes Lyme disease a real yard-level concern here. The sandy uplands and field edges are a rodent reservoir that pushes toward buildings each fall and a soil source for cluster flies. And the woods and wetland cover move raccoons, squirrels, skunks, and bats across the landscape and right up to your walls.
None of this is a problem with the place — it’s the price of a spectacular setting, and it’s the environment BugBoss is built for.
Wildlife removal is the headline service here
In most towns, wildlife is a sideline to pest control. In Navarino it’s front and center, because the corridor guarantees traffic. Bats roost in attics and behind fascia. Raccoons den in chimneys, soffits, and outbuildings, especially in spring. Squirrels chew into attics. Skunks den under decks and sheds, and they’re a rabies concern around pets.
Out here, trapping alone is a losing game — remove one raccoon and the corridor sends another within the week. What actually holds is exclusion: sealing the structure so this animal, and the next one the marsh pushes toward your walls, can’t get back in — plus cleanup of the contamination they leave, from raccoon latrines to bat guano to soiled insulation. For bats, it also means the legal timeline. BugBoss does all of it, and we’re one of the few outfits serving this area that handles wildlife and pests together. See the wildlife removal page and the attic wildlife removal guide for how we work. To be clear about scope: our exclusion work is about animals damaging structures — semi-aquatic animals out in the marsh itself are a DNR or trapper matter, though we’ll gladly advise if something is denning under your boathouse or deck.
Cabins, campgrounds, and waterfront properties
Navarino draws hunters, anglers, and recreation traffic, and that means a lot of seasonal cabins, campgrounds, boat landings, and waterfront properties that all face the same stack of problems at once — mosquitoes, wasps, mice in the off-season, and wildlife testing the buildings. Recreation properties also can’t have pest work disrupting guests. We build the program around the site and keep it discreet, whether that’s a family cabin closed up between hunts or a commercial operation on the water. Our cabin seasonal pest control guide and campground, RV, and marina pest control guide cover both cases in depth.
Mosquitoes on a wetland edge: setting honest expectations
Mosquitoes are the pest people ask about most in Navarino, and it’s worth being straight about what control can and can’t do here. You live beside thousands of acres of protected wetland, and nobody is treating that — it’s a state wildlife area, and the marsh is the point. So any promise to “eliminate” mosquitoes on a property this close to the corridor is a promise no honest company can keep.
What a seasonal program does is different and genuinely useful. Adult mosquitoes don’t spend their day out over the open marsh; they rest in the cool, shaded, humid vegetation close to your house — under deck skirting, in dense shrubs, in the tall grass at the yard’s edge, along the north-facing foundation. Treating those resting sites knocks the local adult population down hard for a stretch at a time, which is the difference between a deck you can’t use after six o’clock and one you can. On top of that, we look for the standing water you actually control — clogged gutters, tarps, buckets, old tires, the saucers under flower pots, low spots that hold water for more than a few days — because every one of those is a breeding site that adds to what the marsh already produces. Draining and correcting those is free control that lasts. The mosquitoes page goes deeper on the biology.
The same honesty applies to timing: mosquito pressure tracks rainfall and heat, so a wet July is worse than a dry one, and a program is about steady management across the season, not a one-and-done. On a wetland edge, that’s the realistic and worthwhile goal.
Living with the nature center and the recreation traffic
Navarino isn’t only farmsteads and cabins — the wildlife area draws steady recreation traffic, and the Navarino Nature Center brings school groups, hikers, skiers, and birders to the edge of the marsh year-round. That mix means the properties here range from quiet family homes to buildings that host the public, and each has its own pest sensitivities. A building that sees visitors can’t have wasp nests over the entrance or a rodent problem in a storage room, and it needs pest work done discreetly and on a schedule that doesn’t collide with programming.
It also means people here tend to care about how pest control is done. Doing exclusion-first work — sealing structures rather than blanketing the property in product — fits a community that lives next to a protected natural area on purpose. Our approach leans that way regardless, because on a wetland edge it’s also simply what works: you cannot out-spray a 15,000-acre habitat, so the durable answer is always to close the building and target treatments precisely where the pest actually is.
Structural pests in river-bottom dampness
Building near the Wolf River and its bottomlands means living with a high water table, and that dampness drives a set of structural pests that drier ground doesn’t. Carpenter ants are the big one: they don’t eat wood, they excavate moisture-softened wood to nest in, and a crawlspace or sill plate that stays damp from a high water table gives them exactly what they want. Spring swarmers at the windows, or big black ants indoors in winter, mean a nest is living inside the heated structure — a job for finding and treating the nest and correcting the moisture, not spraying the trail.
The same damp foundations bring springtails, sowbugs, and the occasional nuisance ant trail up out of the crawlspace, and they make a basement more attractive to overwintering rodents looking for a stable, humid harborage. Near the marsh, the honest fix usually starts with water: grading, gutters, a crawlspace vapor barrier, and drying out the spaces that pests are exploiting. Treat the conditions and the treatments hold; chase the bugs while the crawlspace stays wet and they come right back.
Why a local company beats the national brands here
A wetland-edge property is a specialized environment, and the national brands aren’t built for it. They run dense suburban routes and treat a place like Navarino as the far corner of a territory — and crucially, most of them don’t do wildlife at all, which is half the work out here. BugBoss knows the corridor, handles the raccoons and bats and skunks the pest-only companies won’t touch, and does it with no long-term contract and no cancellation fee. The person who answers the phone is the owner, Brian, and he’s the one who pulls up at your wetland-edge address himself. That’s the whole idea behind our no-contract approach.
How BugBoss handles a Navarino job
Every job runs the same way. We inspect the property inside and out to identify the pest or animal and, just as important, how it’s getting in. We go straight at the source — the nest, the harborage, the breeding site, the roost. We do the exclusion that keeps the corridor out: sealing entry points, closing the building envelope, screening the vulnerable gaps under decks and along the roofline. And we come back to confirm it’s solved, and we stand behind the result with our guarantee.
