Old buildings and open water
Menasha’s wildlife work follows the same split as everything else here. There is the structural side — bats, squirrels and raccoons in the older stock and the postwar neighborhoods, birds on commercial buildings — and the water side along the channel and the lakefront, where the problem is a bank rather than an attic.
And as in the rest of the Fox Valley, the reason a Clintonville company gets called at all is supply. Most pest companies serving this area do not do wildlife. They treat insects and rodents and refer an animal in a wall out — to a trapper who removes it and leaves, or to nobody. Because wildlife work is scheduled rather than same-hour, the 35-minute drive costs you nothing on a normal job.
Bats in the mill-era stock
The older converted buildings near the channel are close to ideal roosts: open wall cavities, unscreened vents, lifted flashing, and the seams where an addition meets original structure. A bat needs about a finger’s width.
In a multi-unit building this gets harder, and it is worth flagging before anyone starts. A colony in a shared structure is one colony using one building — it cannot be handled unit by unit any more than bed bugs can. It needs the whole roofline read at once, coordinated access, and a single schedule. These buildings also tend to have far more entry points than a house, which makes the inspection the long part of the job rather than the treatment.
The good news is that bats do not chew. Unlike rodents, once a gap is properly closed it stays closed, so the exclusion holds well once the finding work has been done thoroughly.
The calendar is binding
Wisconsin protects its bats, and exclusion is prohibited during the summer maternity season while flightless pups are in the roost. Sealing then kills the pups inside the structure — illegal, inhumane, and a considerably worse problem for the owner than the colony was, because what follows is odor and insects in the insulation for months.
A June or July call therefore gets an inspection, a full plan, and a booked date rather than immediate work. We would rather explain that than simply decline. Detail: the Wisconsin bat exclusion law guide and why you cannot evict bats in June and July.
The rest of the structural work
Squirrels — scratching and a rolling sound at dawn and dusk, silence overnight, because they are strictly daytime animals. Roof edges and soffits, usually where an ice dam already lifted the fascia. Chewed wiring is the part to take seriously: rodent-damaged insulation on a live conductor is a fire risk, not a wait-and-see item.
Raccoons — heavy, deliberate movement after dark, sometimes with dragging or chittering. Attics, chimneys, under porches and decks. The most destructive of the group and the most likely to injure a person or a dog, so do not go up to look. Between March and June, assume young until ruled out.
Skunks and groundhogs — under porches, stoops, sheds and decks. Look at the entry, and for young, before closing anything.
Identification by sound before anybody climbs: reading the noise.
Birds, and the legal question that comes first
Birds on signage, parapets, ledges and loading canopies are a routine commercial call here, and it is one of the few jobs where the law is the first thing to settle.
Starlings, pigeons and house sparrows are non-native and are not protected under the Migratory Bird Treaty Act, so they can be excluded and removed directly. Native birds are protected, and acting on a misidentification is a federal violation.
So every bird job starts by confirming the species. After that it is exclusion and deterrence — netting, spikes, ledge modification — plus cleanup and dealing with whatever is drawing them, which is frequently food waste handling. Nuisance birds.
The water side
Muskrats burrow into banks and under retaining structures with entrances below the waterline, so damage stays invisible until a soft spot appears or a section slumps. On a channel or lakefront property the tell is the ground rather than any sighting of the animal.
Beavers show up on the quieter stretches, and they are a water-management problem wearing an animal costume — a dam plugging a culvert floods low ground, and taking the animal without addressing the dam and the drainage solves nothing for long. Wisconsin regulates work on beavers and on waterways, so we will tell you plainly what applies to your situation and what a realistic outcome looks like.
Removal is the easy half
Take tonight’s raccoon and the torn soffit it climbed through is still open next week — and it is the same opening that gives you squirrels in October, wasps in July and fall invaders in September. One repair closes all of it, which is why we quote the whole job rather than the removal alone.
The sequence: inspect from the outside first, because the entry is found by reading the building and there is nearly always more than one. Identify species and season. Get them out with one-way devices where possible. Confirm the space is empty before closing anything. Exclude with hardware cloth and flashing, mechanically fastened, along the whole roofline. Then clean up what needs it, and say honestly what does not.
