Winter in West Michigan brings freezing temperatures, heavy snow, and harsh winds. As the outdoors becomes less hospitable, local wildlife begins searching for warm, safe spaces to survive the season. Unfortunately, this often leads animals into homes, garages, attics, and crawlspaces. Understanding why wildlife comes indoors and what attracts them can help homeowners protect their property while keeping animals safe and unharmed.
Why Wildlife Seeks Shelter Indoors During Winter
As temperatures drop, many species struggle to find food, water, and warmth. Natural shelters such as hollow trees, outdoor burrows, or leaf nests may no longer provide enough insulation from the cold. Animals like raccoons, squirrels, mice, and bats look for stable heat sources and dry shelter, which human structures naturally provide. Homes offer warmth, darkness, and protection from predators, making them an attractive option for wildlife trying to survive winter.
Common Entry Points for Winter Wildlife
Even small gaps and openings can allow animals to sneak inside unnoticed. Mice can fit through holes as small as a dime, and squirrels and raccoons can exploit larger gaps in siding, soffits, or rooflines. Uncapped chimneys, gaps around utility lines, loose shingles, and damaged vents are all common entry points. Once a critter finds a way in, it can quickly build a nest and even attract others, compounding the problem.
Top Cold Weather Critters in West Michigan
Raccoons are skilled climbers and often enter attics to create warm dens. Squirrels, which store food for winter, may invade homes when outdoor temperatures drop. Mice and rats seek warmth and food, making kitchens, basements, and crawlspaces prime hiding spots. Bats may move indoors during cold snaps when their outdoor roosts no longer provide adequate protection. Even skunks or opossums may take refuge under porches or sheds during extreme weather.
Signs of Wildlife Intrusion
Homeowners should be alert to early signs of winter wildlife. These can include scratching or scurrying sounds, droppings in attics or basements, chewed wires or insulation, and unusual odors. Noticing these signs early allows for quicker intervention, reducing damage and the risk of disease exposure.
How to Reduce Winter Wildlife Intrusions
Preventing wildlife from entering your home is often easier than removing them once they are inside. Homeowners can:
-
Seal cracks, gaps, and holes in roofs, siding, and foundations
-
Trim tree branches and shrubs away from the roofline
-
Store food, pet food, and birdseed securely
-
Install chimney caps and repair damaged vents or gutters
-
Conduct seasonal inspections to catch problems early
Taking these steps makes your home less attractive to winter wildlife and minimizes the risk of damage.
