Astor: Green Bay’s oldest neighborhood, and its oldest pest problems
The Astor Historic District covers roughly 39 square blocks in southeast Green Bay, running from E. Mason Street down to Grignon Street and from Webster Avenue west to the Fox River. It was platted in 1835 by A.G. Ellis, and in 1838 it merged with the neighboring Town of Navarino to form what became the city of Green Bay. The oldest structures cluster on the streets nearest the river — the natural ridge along the Fox drained better than the swampy ground to the north, so this is where the first settlers built. The district went on the National Register of Historic Places in 1980, and its greatest run of building came between 1895 and 1929, when Astor housed the city’s business and civic leadership.
For a pest company, that history is the whole story. Astor’s homes span roughly 1835 to 1920 and run the full catalog of nineteenth- and early-twentieth-century construction: Greek Revival, Gothic Revival, Italianate, Queen Anne, and the châteauesque and Prairie-style houses that came later. Beautiful buildings — and every one of them was framed and founded before anyone thought about air-sealing, weatherstripping, or a continuous foundation. That’s exactly what pests exploit.
BugBoss The X-Terminator is not a Green Bay company. We run out of Clintonville, in rural Waupaca County, and Astor sits at the far edge of the metro area we reach. We’re not going to pretend we’re the nearest truck to a downtown Green Bay address. What we are is the specialist worth calling when the problem is an old-house problem — the fall invaders, the rodents in a stone foundation, the carpenter ants in soft old framing, and the wildlife in a big Victorian attic. Those are the jobs the metro franchises either won’t take or won’t do without locking you into a contract, and they’re the jobs we do every week out in old-farmhouse country.
Why old homes leak pests: the Astor entry points
A century-old house has weak points a builder today would never leave open. In Astor we see them in the same places over and over.
The foundations are rubble stone or early block, and after a hundred-plus Wisconsin freeze-thaw cycles they’ve cracked, shifted, and lost mortar. A mouse needs a gap the size of a dime; an Astor foundation offers dozens. Above the foundation, many of these homes use balloon framing — the wall studs run in one uninterrupted vertical channel from the sill plate all the way to the attic. That means a mouse or a cluster fly entering low at the sill can turn up two floors higher, inside a bedroom wall or the attic, with nothing to stop it along the way. It’s why an Astor homeowner finds flies at an upstairs window when the actual entry point is down at the ground.
The rooflines on Queen Anne and Italianate houses are a maze of dormers, turrets, bays, and decorative trim, and every junction is a seam. Soffit and fascia boards have pulled away, original wood-frame windows have gapped at the sash, and the tall old masonry chimneys have lost their caps. Add the deep, spacious attics these homes were built with, and you have ideal harborage for everything from overwintering flies to a bat colony.
Exclusion — physically sealing these openings — is the durable fix, and on an Astor home it takes someone who understands the building, not just someone with a sprayer. Screening a weep hole or a chimney without wrecking the historic character is part of the job.
The fall invaders: Astor’s signature problem
If you own an old home near the Fox River, you know the September-October ritual. Cluster flies, boxelder bugs, and Asian lady beetles mass by the hundreds on the warm south- and west-facing walls, then start finding their way inside. On a warm day in February they reappear at the windows, sluggish and confused, and it feels like a fresh infestation — but it’s the fall population waking up in your wall voids.
Cluster flies are the worst of them here, and they have nothing to do with how clean your house is. Their larvae parasitize earthworms in the soil, so any home near the river corridor, old lawns, and mature plantings produces them regardless of housekeeping. Boxelder bugs feed on boxelder and maple seeds — trees Astor has in abundance — and Asian lady beetles pile in right alongside them. All three overwinter in the same wall voids and attics.
The control that actually works is a timed early-fall exterior treatment on those sunny walls, combined with sealing the seams they use to get in. Do it in late August or early September, before the masses arrive, and you head off the whole winter’s problem. Wait until they’re already inside and you’re left vacuuming. Our cluster fly control guide lays out the timing, and if you’ve already got them stacking up at the glass, the cluster flies in windows page covers what to do about it.
Carpenter ants and mice in a hundred-year-old house
Carpenter ants love Astor. They don’t eat wood — they excavate it to nest — and they go for wood that’s already been softened by moisture. A century of small roof leaks, gutter overflow, ice dams, and drips around old plumbing has left soft spots in sills, window bays, and framing throughout these homes. Big black ants active indoors in the dead of winter mean a nest inside the heated structure, not foragers wandering in. Winged swarmers at the windows in spring mean the same thing. Fixing it means locating the nest, treating it, and correcting the moisture that invited it — see the carpenter ants page.
Mice are the other constant. They peak from September through November, and an old foundation full of settlement cracks is an open door. Because balloon-framed walls let them travel vertically, a mouse that enters at the sill can nest in the attic insulation two floors up. Trapping clears the ones already inside, but the fix is sealing the building — every gap, at the foundation, the utility penetrations, and the old coal-chute and basement-window openings these homes tend to have. The mice page walks through where they get in.
Wildlife in Astor: bats, squirrels, and old chimneys
Astor’s old attics and tall masonry chimneys make it some of the best wildlife habitat in the city, and this is where a rural specialist genuinely earns the drive from Clintonville.
Bats roost in the big open attics and behind loose fascia on these Victorians. Getting them out is not a spray job and it’s not a job you can do whenever it’s convenient — Wisconsin protects its bats, and four cave species are state-threatened. The DNR requires one-way bat exits to stay open June 1 through July 31, during the maternity season when flightless pups are in the roost. Sealing the building then traps and kills the pups, which is both illegal and a far worse mess. We do exclusion 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 details are in our Wisconsin bat exclusion law guide, the bats page, and the bats in attic walkthrough.
Squirrels chew into attics at aged roof edges, gable vents, and rotted fascia — a squirrels in attic job that ends with sealing every access point, not just trapping the one you saw. Raccoons treat Astor’s old uncapped chimneys as ready-made dens, especially females raising young in spring; that’s a raccoon in chimney situation that calls for humane removal and a proper chimney cap. All of this is our wildlife removal work, and the attic wildlife removal guide covers how we button up an old attic afterward. Most pest-only outfits reaching Astor from the metro won’t touch any of it — see the raccoons and squirrels pages.
Honest positioning: the rural specialist at the metro edge
Here’s the straight version. BugBoss is a Clintonville-based, family-owned company — owner Brian Zahringer runs the truck and answers the phone. Our home ground is rural: farmhouses and lake cabins out around Pulaski, Bonduel, and Shawano. Astor is the eastern edge of what we reach, and we won’t pretend otherwise. For a quick one-off in downtown Green Bay, a company inside the city is closer.
Where we’re the better call is on the work we do best: old-home exclusion, fall invaders, carpenter ants, and wildlife — the specialized, problem-first jobs that reward someone who’s spent years sealing century-old buildings out in the country. We do pest control and wildlife removal both, which the metro pest franchises generally don’t, and we do it with no long-term contract and no cancellation fee. You’re not signing up for a route; you’re hiring a specialist for a specific problem. That’s the whole idea behind our no-contracts approach, whether it’s a residential job or a commercial building.
How we work, and when to call
Every job runs the same way. We inspect the whole property, inside and out, and identify both the pest and the way it’s getting in. We treat the source — the nest, the roost, the breeding site — not just what’s visible. We do the exclusion that keeps the next wave out, sealing entry points and correcting the moisture behind the problem. And we follow up to confirm it’s gone.
Call BugBoss when you’ve got fall invaders stacking up 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 old Astor home, those are exactly the jobs we’re built for. Reach us at 866-BUGBOSS, or request a quote. We’ll tell you honestly whether we’re the right fit — and if we are, we’ll get it solved without a contract.
