Where two rivers meet
New London is a river town in the truest sense — it sits right where the Embarrass River empties into the Wolf, and the two of them have shaped the place since before it had a name. About 7,300 people live here, split across the Waupaca–Outagamie county line that runs through the city, and the town grew up in the 1850s as a lumber center and the head of steamboat navigation on the Wolf, the point where boats coming up from Oshkosh could go no farther. A founder named Reeder Smith named it after New London, Connecticut, his father’s home. Two other bits of local color tell you a lot about the town’s character: it’s the birthplace of the American Water Spaniel, the breed developed here that became Wisconsin’s state dog, and every March the whole city famously turns itself into “New Dublin” for what’s billed as Wisconsin’s largest St. Patrick’s Day parade and Irish Fest.
For pest control, the rivers are the whole story. A confluence means low ground, damp soil, abundant cover, and standing backwater — and every one of those drives a specific set of pests. New London’s housing sits close to the water on both rivers, with a good stock of older river-town homes and a band of riverfront and near-river properties that see moisture and wildlife pressure their up-the-hill neighbors don’t. Ring the town with the farm country of Waupaca and Outagamie counties and you’ve got the classic rural-Wisconsin pest reservoir on top of the river dynamics. BugBoss The X-Terminator works this ground every week. We’re based just west in Clintonville, we cover both sides of the county line the same way, and we do both pest control and wildlife removal — which on riverfront property, where bats and raccoons are as common a call as mice, matters a great deal.
The New London pest calendar, season by season
Spring (March–May): high water, swarmers, and St. Patrick’s Day
Spring on the rivers means high water and softening ground, and both push pests toward the buildings. Rising river levels flood the low cover along the banks and move rodents and other ground dwellers toward higher, drier ground — which often means your foundation. Mice that wintered indoors start breeding and ranging, and the overwintering cluster flies and boxelder bugs wake on warm days and crawl toward the windows. That’s the fall population coming out of dormancy, not a new invasion, and it’s a sign the building was never sealed.
Spring is also carpenter ant season, and New London’s riverfront and older homes are especially prone because they hold moisture. Carpenter ants nest in moisture-damaged wood — around a leaking roof, a damp sill plate near the water table, or a deck sitting on wet soil. In April and May, winged swarmers appear at windows and big black ants show up indoors; seeing them early, before the ground fully warms, usually means the nest is inside the heated structure. Our carpenter ants page covers what to look for. And when the town becomes New Dublin in mid-March, the parade crowds and the food service that feeds them create a short, intense burst of crowd-driven pest pressure on downtown venues — worth getting ahead of, not scrambling to catch up on.
Summer (June–August): river mosquitoes, stinging insects, and the bat window
Summer is mosquito season, and New London gets it worse than most towns we serve, for a simple reason: two rivers meeting means twice the slow backwater and wet ground that mosquitoes breed in. Riverfront yards feel it worst in the evenings. A seasonal mosquito program that treats the shaded vegetation where they rest by day and knocks back the standing water they breed in is what makes a riverfront deck or backyard usable through the summer.
Stinging insects peak in this stretch. Paper wasps nest under eaves and porch roofs, yellowjackets set up in the ground and in wall voids, and bald-faced hornets build their gray aerial nests in the mature trees along the rivers. By August the colonies are largest and most defensive, and that’s when most of our wasp and hornet calls come in.
Summer is also the one window when we cannot seal bats out. Wisconsin protects its bats, and the DNR requires that exits stay open June 1 through July 31 during the maternity season, when flightless pups are in the roost. Seal a New London attic then and you trap the pups inside — illegal, and a worse mess than the colony. If you find bats in summer, we schedule the exclusion for the legal window. The details are on our bats page and in the Wisconsin bat exclusion law guide.
Fall (September–October): the busiest season in town
Fall is the defining season for New London pest control. As the nights cool, the fall invaders — cluster flies, boxelder bugs, and Asian lady beetles — mass on the warm south and west walls and work into every gap, heading for the wall voids and attics. At the same time, mice begin their annual push indoors as the surrounding fields and fencerows go cold.
Cluster flies are worth calling out in a farm-ringed town like New London, because people blame their houses when they shouldn’t. Cluster fly larvae parasitize earthworms in the soil, so any property surrounded by lawn, field, or riverbank — which is nearly all of New London — grows its own population regardless of how clean the home is. The fix is an early-fall exterior treatment of the walls they gather on, paired with sealing the gaps at soffits, windows, and penetrations. Our cluster fly control guide lays out the timing. For homes near the fields, our farmhouse rodent exclusion guide covers the mouse side of the fall push.
Winter (November–February): the payoff and the pests already inside
By winter the outdoor invasion is over, and whatever got in during fall now has the building to itself. Mice breed year-round once warm and fed, so a handful in November becomes a real infestation by February if the entry points aren’t closed. A thaw in January warms the wall voids of a river-town home and coaxes the overwintering cluster flies back to the windows. And winter is travel-pest season — holiday travel brings bed bugs home as hitchhikers, a problem tied to luggage and used furniture, not to cleanliness. Winter work in New London is mostly rodent exclusion, cleanup of the fall invaders, and anything that arrived in a suitcase.
New London’s housing stock: riverfront, downtown, and rural
Pests exploit specific weaknesses, and New London’s building stock gives them plenty to work with.
The riverfront and near-river homes on both the Wolf and the Embarrass are the type that needs the most attention. Proximity to water means a high water table, damp crawlspaces and basements, and sill plates that stay wet — exactly the conditions carpenter ants, springtails, and other dampness pests want. Many of these homes are older, with stone or block foundations and the settlement gaps that come with a building on soft river-bottom soil, and the natural cover along the banks hands rodents and wildlife a covered route right to the foundation. Riverfront property rewards a careful moisture-and-exclusion approach more than almost any other kind.
The older downtown and near-downtown homes dating to the lumber era tend toward stone or rubble foundations, balloon framing, and decades of small gaps. Balloon-framed walls are open vertical channels from basement to attic — the route a mouse entering at the sill plate uses to reach the top floor, and the route cluster flies use to move from a soffit gap into a bedroom. And the rural farmsteads ringing town on both sides of the county line bring the full agricultural picture: pole barns, outbuildings, and older farmhouses with the rodent pressure of living next to open field.
Geography and ecology: the confluence drives everything
The confluence of the Wolf and Embarrass Rivers is the defining ecological fact of New London, and it drives pest pressure in every direction. Slow backwater and wet ground are prime mosquito habitat. Damp foundations and high water tables draw carpenter ants and dampness pests. The wooded riverbanks are prime wildlife country and prime tick habitat — ticks thrive where mowed lawn meets the brush and cover along the banks, exactly the edge that defines a riverfront lot. Our tick and Lyme yard program is built to push that pressure back from the yard and the riverbank path.
The surrounding farmland of both counties is the reservoir for the fall invaders and rodents that show up every autumn — cluster flies off the field soil, mice out of the harvested fields and fencerows. Between the rivers and the fields, New London gets both the water-driven and the farm-driven pest picture at once, which is why exclusion here has to account for moisture and access both.
Wildlife in New London: attics, chimneys, and the law
Along two rivers lined with mature trees and older homes, wildlife work is a regular part of what we do in New London, not a sideline. Bats roost in attics and behind fascia; raccoons den in chimneys and torn soffits, especially females raising young in spring; squirrels chew into attics through weak roof edges; and skunks den under decks, porches, and outbuildings.
With two rivers pushing wildlife up the banks, trapping is only ever half the answer; exclusion — sealing the chimney, soffit, and roof edge so this animal and the next can’t get back in — is what makes it stick, with bats handled on the legal timeline. BugBoss does the removal and the sealing, and scrubs out what they leave: the raccoon latrine, the bat guano, the fouled insulation. Most of the pest-only companies serving this area won’t touch wildlife; we handle it under the same roof. See our wildlife removal page and the attic wildlife removal guide for the full approach.
Commercial pest control in New London
New London has a real commercial base for a town its size — a working downtown business district, restaurants, lodging, food service, and manufacturing — plus the seasonal spike that comes with the New Dublin St. Patrick’s Day celebration and the summer river traffic. Each of those has its own pests and its own record-keeping needs. A restaurant needs documented, inspection-ready rodent and fly management. A hotel needs discreet service and a bed bug protocol. A manufacturer needs stored-product and rodent control that survives an audit.
BugBoss builds commercial programs around the specific operation, keeps the service records you need on hand, and schedules discreetly so pest work never disrupts your business or your customers. Because you deal with the owner directly, there’s a real person accountable for the result.
New London’s location on the Wolf also brings summer boating and river traffic — boat launches, riverfront restaurants and taverns, and the docks and landings that come with a navigable waterway. Those waterfront operations carry the same pressures a lakefront resort does: wasps around outdoor seating, flies and rodents drawn to food service and waste bins, and the constant mosquito load the river throws off in the evening. A program built for a riverfront business has to treat the outdoor customer areas as seriously as the kitchen, because that’s where a pest problem actually costs a place its trade.
Spiders, ants, and the rest of the New London picture
Beyond the mice, cluster flies, and wildlife, a river town grows its own supporting cast. Spiders are a steady complaint on riverfront and porch-heavy homes, because the same damp, insect-rich air along the water that feeds mosquitoes also feeds spiders — an exterior light near the river becomes an all-night buffet, and the webs follow. Knocking back the insect supply and sealing the gaps does more for a spider problem than chasing webs with a broom. Our spiders page covers the common species.
Ordinary ants — the small trailing kind, not carpenter ants — track in on moisture and food, and a kitchen near a damp river foundation is a reliable draw; our ants page explains why the source matters more than the trail. On the farm edges of town the mice pressure runs heavy every fall, and skunks denning under decks and outbuildings are a routine spring call. Each is its own problem with its own fix, which is why a one-size perimeter spray rarely settles anything for long in a town this varied.
Exclusion is the part that lasts in New London
The durable fix in New London is exclusion, not repeated spraying — and on riverfront property it has to start with moisture, because a wet foundation is what draws carpenter ants and dampness pests in the first place. We look hard at grading, gutters, crawlspace ventilation, and sill plates that sit close to a high water table, and we correct what we can before we seal. Then the sealing itself gets specific: utility and pipe penetrations, where the opening is always larger than the pipe; the sill-plate gap where the frame meets a stone or block foundation; garage-door corners and door sweeps; and the soffit and fascia junctions and weak roof edges that squirrels, bats, and raccoons use to reach the attic. On an older river-town home with balloon framing, closing the entry at the foundation is what stops a mouse from turning up two floors above where it got in. That combination — dry the building out, then close it up — is what makes the fix hold after we’ve gone.
Why a local company beats the national brands here
The national pest companies are built for dense suburbs where a truck can hit fifteen stops in a tight box. New London is a river town spread along two waterways and ringed by farm country, where value comes from local knowledge and fast response and from working with someone who understands what river moisture does to a foundation, knows a cluster fly from a stable fly and a big brown bat from a little brown one, and can tell a moisture-driven carpenter ant problem from a harmless ant trail.
The complaint we hear most about the big brands is the contract — the lock-in, the cancellation fees, the missed appointments, the support line that can’t help. BugBoss is built the other way: no long-term contract, no cancellation fee, and it’s the owner who takes your call and pulls into your drive. That’s the core of our no-contract approach, and it fits a river town where problems are seasonal and nobody wants to pay year-round for a spring mosquito issue.
How BugBoss handles a New London job
Every New London job runs the same disciplined way. We inspect the property inside and out to identify the pest and, just as important, how it’s getting in. We treat the source — the breeding backwater, the nest, the harborage — instead of fogging the whole property and hoping. We do the exclusion that keeps the next wave out: sealing entry points, closing the gaps in the building envelope, and drying out the river-damp foundation that invited the problem. And we follow up to confirm it’s actually gone, standing behind the work with our guarantee. Whether it’s a residential mouse job on a riverfront lot or a bat colony behind the fascia, the method is the same: find it, fix the source, seal it out, and prove it worked.
