Old buildings, and woodlots supplying the animals
Tigerton’s building stock is what makes it steady wildlife country. Farmhouses with deep attics and original soffit runs, barns, granaries, machine sheds — structures built long before anybody thought about sealing them, standing next to woodlots that supply a continuous population of animals looking for somewhere to overwinter or raise young.
The other half of the picture is supply of a different kind. Most pest control companies do not do wildlife. They will treat insects and rodents and refer an animal in a wall out to a trapper who removes it and leaves, or to nobody at all. Out here it is frequently nobody, which is why we learned to do the animal and the building as one job.
The honest conversation about barns
A house can be sealed. A century-old barn largely cannot — not economically, and not truthfully. Open gables, board gaps, a loft the size of a small warehouse and a dozen ways in mean that anyone quoting you full exclusion on an old barn is selling something they cannot deliver.
What does work is deciding what actually has to be protected and sealing that: the feed room, the tack room, the office, the milk house, the part of the loft you use. The rest gets treated as what it functionally is, which is covered outdoor space.
On the farmhouse, by contrast, full exclusion is absolutely worth doing and it holds for years.
What turns up, and how to tell before anybody climbs
The time of day the noise happens does most of the identification.
Squirrels — scratching and a rolling sound at dawn and dusk, silence overnight. Strictly daytime animals. Soffits and roof edges, usually where an ice dam already lifted the fascia. The chewed wiring is the part to take seriously.
Bats — squeaking and a dry rustle at dusk from a wall, soffit or peak; greasy staining at an exterior gap; droppings collecting below. Farmhouse attics and barn lofts both. Legal calendar applies.
Raccoons — heavy, deliberate movement after dark, dragging, sometimes chittering. If it sounds like a person is up there, it is one of these. The most destructive and the most likely to injure a person or a dog; do not go up to look.
Skunks and groundhogs — under granary floors, sheds, decks and stoops. Look at the entry, and look for young, before closing anything.
Woodpeckers — on wood-sided buildings, and federally protected, so the toolkit is deterrence, exclusion, insect control and repair rather than removal. Often the bird is there because there are insects in the siding, which is the real fix.
The longer version: reading the noise before you call anyone.
Bats: the calendar is binding
Wisconsin protects its bats, and exclusion is prohibited during the summer maternity season while flightless pups are in the roost. Seal then and the pups die inside the structure — illegal, inhumane, and a far worse problem for you than the colony was, because what follows is odor and insects inside the insulation for months.
A June call therefore gets an inspection, a full plan and a booked date. 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.
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 every fall invader on the property 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 outside first, because the entry is found by reading the building rather than starting in the attic, and there is nearly always more than one. Identify species and season, since that decides what is legal and humane. Get them out with one-way devices where possible. Confirm the space is empty before closing anything. Exclude with heavy-gauge hardware cloth and metal flashing, mechanically fastened — not foam in a hole, which a determined animal removes overnight. Then clean up what needs it, and say honestly what does not.
One property, one visit
The advantage of doing both trades is that a farmstead gets handled as one place. The bats in the barn, the raccoon in the chimney, the rodents in the pole barn and the fall invaders on the farmhouse are one property and one conversation, rather than three contractors who each solve a quarter of it.
