Bats
Older houses with gable vents, loose trim and slate or cedar shake roofs often have bats. The Moodna marsh and the river supply plenty of insects for them.
Town of Cornwall · ZIP 12518
Few towns in Orange County have this much forest this close to their houses. Storm King, Black Rock Forest and Schunemunk Mountain ring Cornwall, and Moodna Creek runs right through it. That means bats, raccoons, carpenter ants and damp basements in neighborhoods that otherwise look completely suburban.
Rodent calls peak in November. Mice and rats are pushing into heated spaces as overnight temperatures drop into the 20s. Sealing gaps now saves a long winter of traps.
Cornwall was settled by Scottish colonists in the 1680s and took its current name in 1797. In the 1800s it became a health retreat and summer resort for New Yorkers who came up the Hudson for mountain air. About 12,900 people lived here at the 2020 Census, spread across roughly 28 square miles.
The town is shaped by its landforms. Storm King Mountain rises over the river to the southeast, and the 1960s fight to stop a power plant on it became one of the founding battles of the American environmental movement. Black Rock Forest, a research forest established in the late 1920s and later held by Harvard, covers much of the high ground to the south. Schunemunk Mountain, the town's highest point at about 1,540 feet, rises to the west.
Moodna Creek winds through the valleys between them, past the old mill hamlets, under the tall Moodna Viaduct rail trestle and into a tidal marsh at the Hudson. Cornwall includes the village of Cornwall-on-Hudson, the hamlet of Mountainville, and smaller places like Firthcliffe, Canterbury and part of Salisbury Mills.
All that woods and water means wildlife lives close to Cornwall homes, and houses built in the resort era and the decades after have plenty of ways in. Bats, raccoons and squirrels head the wildlife list. Carpenter ants and termites go after older wood, and moisture pests thrive in basements near the creek.
The resort years left a mark on the housing stock. In 1846 the writer Nathaniel Parker Willis settled on an estate he called Idlewild, and the name lives on in local streets and a park. Big summer houses and boarding homes from that era were built with deep porches, tall attics, slate roofs and stone cellars. Many have been modernized inside, but the rooflines and foundations are original, and those are the parts animals test first.

Older houses with gable vents, loose trim and slate or cedar shake roofs often have bats. The Moodna marsh and the river supply plenty of insects for them.
Chimneys, attics and crawlspaces near the forest edges. Raccoons are a rabies vector, so removal should be handled by a licensed pro.
Very common in wooded neighborhoods. They nest in damp wood around windows, decks and porches, and in nearby dead trees.
Gray and red squirrels chew into soffits and attics from overhanging oaks and maples.
Fieldstone foundations and old sills in historic homes let mice in easily. Newer homes near the woods see deer mice in fall.
Subterranean termites are present throughout the valley. Older homes and those with wood touching soil are most at risk.
A licensed wildlife pro inspects the roof, chimney, vents and foundation to find how animals are getting in.
Depending on the animal, they use one-way exits, live traps or hand removal, following DEC rules for licensed operators.
Entry points are closed with durable materials, and chimney caps or vent covers go on so nothing moves back in.

Hiring for bats in Cornwall? Check the calendar first.
Bats raise their young in attics from roughly June through mid-August. Sealing a house during that window traps flightless pups inside, which is both cruel and a smell problem you do not want. A reputable provider will inspect now and schedule exclusion for late summer or early fall. If a bat ends up in a bedroom where someone was sleeping, contact the health department about testing.
With Black Rock Forest and Storm King so close, a lot of Cornwall searches are for "wildlife removal near me" or "bat removal near me." The providers we connect you with hold the DEC Nuisance Wildlife Control Operator license required for paid wildlife work in New York, and many also handle insects and rodents.
If you are in town, the village or Mountainville and searching "exterminator near me" for ants, mice or termites, the same call works. We match you with an independent local pro who covers your area.
★★★★★“Skunk under the front porch the week before our daughter's graduation party. Handled fast, and they screened the gap so it can't happen again.”
★★★★★“We kept hearing scratching behind the kitchen wall of our rowhouse. The tech found where they were coming in along the gas line and had it sealed the same afternoon.”
★★★★★“House centipedes all over the finished basement. They pointed out the dehumidifier wasn't keeping up. Treated the perimeter and fixed the humidity. Big difference.”
Much of the town borders forest, and carpenter ants live in dead trees and stumps there. When a house has damp wood from a leak or poor drainage, they move in. Finding and treating the nest, plus fixing the moisture, is the usual solution.
Timber rattlesnakes live in parts of the Hudson Highlands. They are a protected threatened species in New York and should never be harmed. If one is near your home, keep your distance and call for a licensed pro who can relocate it legally.
