Top Pest & Wildlife Problems in Northern Wisconsin (And How BugBoss Solves Them)
From Mice in the Walls to Bats in the Attic—Here’s What Every Northwoods Homeowner Should Know
Living in Northern and Central Wisconsin means enjoying the outdoors, the woods, the lakes—and unfortunately, a steady stream of pests and wild critters that love sneaking into your home just as much as you love being in theirs.

At BugBoss The X-Terminator, based in Clintonville, we understand the unique challenges that come with owning a home, cabin, or business in Wisconsin’s Northwoods. From mice in crawlspaces to raccoons in the attic, we tackle it all with proven strategies and local expertise.
Here are some of the most common pest and wildlife problems we handle—and how we get them out, and keep them out.
1. Mice and Rodents
As soon as the temperatures drop, mice and voles start looking for warm shelter—and your home is a prime target. Once inside, they chew wires, damage insulation, and leave behind droppings that carry health risks.
What to watch for:
- Droppings along walls, cupboards, or drawers
- Scratching sounds in ceilings or behind walls
- Chewed packaging, wiring, or insulation
Our solution:
BugBoss provides strategic trapping, sealing of entry points, and long-term rodent-proofing to prevent future infestations.
2. Bats in the Attic
Bats love quiet, dark, warm places—like your attic. While protected under Wisconsin law, bat colonies can cause serious problems if left unchecked, especially with the buildup of droppings (guano) and the risk of disease.
Signs you have bats:
- Squeaking or fluttering at dusk or dawn
- Accumulated droppings near vents or under eaves
- A strong ammonia-like odor upstairs or in the attic
Our solution:
We perform humane bat exclusions using one-way exit valves during the legal removal season, then seal all entry points to prevent re-entry—always in compliance with state regulations.
3. Raccoons and Squirrels
Raccoons are crafty. Squirrels are relentless. Both can chew, claw, and tear their way into attics, garages, and soffits. Once inside, they’re noisy, destructive, and dangerous to your home’s wiring and insulation.
Common signs:
- Heavy scratching or thumping sounds at night
- Torn roof vents or soffits
- Insulation displaced or damaged
Our solution:
BugBoss traps and safely removes wildlife, reinforces vulnerable areas, and installs exclusion barriers to keep them from coming back.
4. Carpenter Ants and Wood-Destroying Insects
Northern Wisconsin’s damp climate makes homes especially susceptible to carpenter ants and other wood-destroying pests. Left untreated, they can cause structural damage over time.
What to look for:
- Fine sawdust piles (frass) under wood surfaces
- Visible ant trails, especially near kitchens or basements
- Hollow-sounding or soft wood in framing or trim
Our solution:
We find and treat the source of the colony with targeted insecticides and provide ongoing protection to prevent reinfestation.
5. Cluster Flies, Boxelder Bugs & Asian Lady Beetles
In the fall, these pests swarm siding, windows, and attics in search of winter shelter. While not dangerous, they can become a serious nuisance once they make it inside.
Signs you’ve got a problem:
- Insects gathering around sunny siding or window trim
- Clusters found in attics or window sills
- Repeated invasions each fall
Our solution:
We offer seasonal perimeter treatments and sealing services to block entry points and keep these overwintering pests out of your living space.
