East De Pere: the original city on the river
De Pere is split down the middle by the Fox River, and the two sides have different histories and different housing. The east side is the original De Pere. When the city was first platted in 1836 by John Penn Arndt and Charles Tullar, and when the 1839 division created separate towns, De Pere sat on the east bank while the west side remained part of Howard until the two consolidated in 1890. The name itself comes from “Rapides Des Pères” — the rapids of the fathers — after the St. Francis Xavier Mission that Father Claude-Jean Allouez established at the rapids in 1671. Today the city holds about 25,410 people across both banks.
For pest control, the east side reads as two zones. Near the historic downtown and the riverfront you have the older, settled housing — homes from the late 1800s and early 1900s with the entry points that come with age. Extend away from the river and you reach the mid-century and newer east-side neighborhoods. Both get pests; they just let them in differently.
BugBoss The X-Terminator is not a De Pere company. We run out of Clintonville, in rural Waupaca County, and the east side of De Pere sits at the edge of the metro area we reach. We won’t pretend we’re the nearest truck to a riverfront address. What we are is the rural exclusion and wildlife specialist worth calling when the problem is one we’re built for — fall invaders, rodents, carpenter ants, and attic wildlife — the work we do every week on old farmhouses out in the country, and the work the metro franchises won’t take without a contract.
Older riverfront homes: where the pests get in
An older home near downtown De Pere has weak points a builder today would seal automatically. The foundations — early poured concrete, block, and some stone — have settled and cracked over a century of Wisconsin freeze-thaw, and a mouse needs only a dime-sized gap. Soffit and fascia boards have loosened, aging windows have gapped at the sash, and older masonry chimneys near the river have lost their caps. Many of these homes have real, spacious attics — good harborage for overwintering insects and wildlife.
The newer east-side neighborhoods are tighter but predictable. Fall invaders and mice exploit the construction junctions: soffit returns and ridge vents, weep holes in brick veneer, gaps around HVAC and plumbing penetrations, garage-door corners, and unsealed sill plates behind the siding. New construction changes where you seal, not whether you have to.
Exclusion — physically sealing the openings — is the durable fix on either type, and it takes someone who understands the building. That’s the core of what we do.
The fall invaders: the east side’s signature problem
Every September and October, east-side De Pere gets the wave that hits every riverfront, tree-lined neighborhood in our territory. Cluster flies, boxelder bugs, and Asian lady beetles mass on the warm south- and west-facing walls, then work inside to overwinter. On a mild day in February they wake in the wall voids and turn up at the windows, looking like a fresh invasion.
Cluster flies are the worst of them, and they have nothing to do with housekeeping. Their larvae parasitize earthworms in the soil, so any home with established lawns near the Fox River corridor produces them regardless of how clean it is. Boxelder bugs feed on boxelder and maple seeds — trees De Pere has in abundance — and Asian lady beetles pile in beside them. All three overwinter in the same wall voids and attics.
What works on the east bank is a timed early-fall exterior treatment on the river-facing and south walls that catch the afternoon sun, together with sealing the seams the flies actually use. Late August into early September, before they mass on the siding — treat after they are in the wall and you have missed the year. Our cluster fly control guide covers the timing, and if they are already stacking up on the glass, see cluster flies in windows.
Carpenter ants and mice near the river
Carpenter ants thrive in older riverfront housing. They don’t eat wood — they excavate it to nest — and they target wood already softened by moisture. Decades of small roof leaks, gutter overflow, ice dams, and drips around aging plumbing leave soft spots in sills, window bays, and framing. Big black ants active indoors in winter mean a nest inside the heated structure; winged swarmers at the windows in spring mean the same. Fixing it means locating the nest, treating it, and correcting the moisture — the carpenter ants page explains why humidity near the river makes it worse.
Mice peak September through November, and settled foundations near the water are open doors. Trapping clears what’s inside; sealing the building — foundation, penetrations, garage corners, and soffit gaps — is what stops the flow. The mice page walks through where they get in. And wasps and hornets round out the warm season, nesting under eaves and deck structures and turning aggressive in August.
Wildlife along the Fox River and the dam
The Fox River and the greenway around the De Pere dam bring wildlife right up to east-side rooflines, and this is where a rural specialist earns the drive from Clintonville. Homes near the water see more attic and chimney intrusions than an interior lot.
Bats roost in the older attics and behind loose fascia. Exclusion is legally restricted — Wisconsin protects its bats, and the DNR keeps one-way exits open June 1 through July 31 during the maternity season, when flightless pups are in the roost. Sealing then traps and kills the pups, which is illegal and a worse mess. We do the work in the legal window: find the exits at dusk, install one-way doors, wait at least a week, then seal and clean up the guano. The rules are in our Wisconsin bat exclusion law guide, and the process is on the bats and bats in attic pages.
Squirrels chew into attics at aged roof edges and gable vents — a squirrels in attic job that ends with sealing every access point. Raccoons den in older chimneys and torn soffits, especially females in spring; that’s a raccoon in chimney situation needing humane removal and a proper cap. All of it is our wildlife removal work, detailed in the attic wildlife removal guide, and it’s the capability the metro pest franchises generally don’t offer — see the raccoons and squirrels pages.
Beyond the fall invaders: the rest of the east-side picture
Cluster flies, mice, and wildlife lead the list, but the east side carries a broader mix. Nuisance ants — pavement ants trailing out of driveway, sidewalk, and patio cracks, and odorous house ants in the kitchen — are a common warm-season call, especially in the newer neighborhoods. These aren’t the wood-damaging carpenter ants, and spraying the visible trail only scatters them; the fix is treating the colony at its source.
Spiders follow their food. They gather where the insect supply is good — porches, garages, and eaves that pull in flying insects at night, and the well-lit doorways of the older downtown homes. Sweeping webs off the soffit does nothing lasting; an exterior program that knocks down the insects they feed on is what actually thins them out.
Ticks matter along the river greenway and the wooded edges of the newer east-side subdivisions, where lawns meet cover. Deer ticks carry Lyme disease and wait in the tall grass along those margins, so families with kids and dogs backing onto green space are the ones at risk. A perimeter treatment targets that transition zone.
Downtown De Pere near the dam is a genuine draw — a walkable business district, riverfront events, restaurants and taverns — and warm-weather crowds and food concentrate stinging insects and rodents around venues and the buildings near them. And winter on the east side is mostly about what already got in during fall: mice breeding in a warm wall void, and overwintering flies and beetles waking at the windows on a mild day. Sealing in September and October is what keeps the winter quiet, which is why we push fall exclusion instead of chasing individual insects through the cold months.
Honest positioning and how we work
Here’s the straight version. BugBoss is Clintonville-based and family-owned — owner Brian Zahringer runs the truck and answers the phone. Our home ground is rural country out around Pulaski, Bonduel, and Shawano. The east side of De Pere is the metro edge of what we reach, and for a quick one-off a company inside the metro is closer.
Where we earn the call is the problem-first work the east-bank housing stock generates: exclusion on older homes, fall invaders, carpenter ants, and wildlife. We do pest control and wildlife removal both, which is rare among the companies working this side of the river, and we do it with no long-term contract and no cancellation fee. You are hiring a specialist for one problem rather than signing onto a route — that is the whole point of our no-contracts approach, on a residential job or a commercial building alike.
Every job runs the same way. We inspect inside and out — foundation, sills, soffit line, attic, and the river-corridor conditions around the property. We treat the source, not the insects you happen to be looking at. We do the exclusion that keeps the next wave out, which on these older east-bank houses is the step that actually ends the cycle. And we follow up to confirm it worked.
Call BugBoss when you’ve got fall invaders on the windows, carpenter ant swarmers indoors in spring, mice you can’t trap your way out of, or scratching in the attic that turns out to be bats, squirrels, or a raccoon. For an older east-side De Pere home, those are exactly the jobs we’re built for. Reach us at 866-BUGBOSS, or request a quote. We’ll be honest about whether we’re the right fit — and if we are, we’ll solve it without a contract.
