Michigan Winters and Wildlife Invasions: How To Protect Your Home
As the temperature drops in Michigan, humans aren’t the only ones seeking warmth—wildlife is, too. Raccoons, squirrels, mice, and even bats look for shelter from the freezing weather, often finding their way into attics, basements, and crawl spaces. These uninvited guests can cause structural damage, spread disease, and create costly repairs if left unchecked.
To protect your home this winter, it’s essential to understand why animals seek shelter, the common signs of wildlife invasions, and the best ways to keep them out.
Why Winter Wildlife Invasions Happen
Michigan’s cold, snowy winters make survival difficult for wildlife. Animals enter homes primarily for three reasons:
Warmth – Attics, basements, and wall voids provide insulation from freezing temperatures.
Food – Leftover pet food, unsecured garbage, and even pantry items can attract hungry critters.
Shelter – Wild animals seek safe nesting areas to protect themselves and their young from the harsh elements.
Common Winter Wildlife Invaders in Michigan
Several species in Southeast Michigan become problematic during winter, including:
Raccoons – Known for their intelligence and dexterity, raccoons can pry open vents and chimneys to access attics.
Squirrels – These rodents chew through wood and insulation, often nesting in attics or walls.
Mice and Rats – Small rodents can squeeze through tiny gaps, contaminating food and spreading disease.
Bats – Though hibernating, bats may still be present in attic spaces and can pose health risks.
Skunks – Often burrowing under porches and sheds, skunks seek refuge from the cold.
Signs of a Wildlife Infestation
Early detection is key to preventing serious damage. Look for these common signs:
✔️ Scratching, scurrying, or chirping noises in walls or ceilings
✔️ Droppings in attics, basements, or near food sources
✔️ Unpleasant odors, often from urine or nesting materials
✔️ Chewed wires, insulation, or wooden structures
✔️ Visible entry points around vents, chimneys, and roofing
How to Protect Your Home from Wildlife Invasions
Seal Entry Points
Inspect your home’s exterior for holes, cracks, and loose siding. Use steel mesh, caulk, or weatherproof materials to seal openings. Pay extra attention to:
- Roof vents and soffits
- Chimneys (install a chimney cap)
- Gaps around doors, windows, and pipes
Secure Food Sources
Eliminate anything that might attract wildlife, including:
- Storing garbage in tightly sealed bins
- Removing pet food from outdoor areas
- Keeping bird feeders away from the house
Trim Trees and Landscaping
Overhanging tree branches act as bridges for squirrels and raccoons. Trim branches at least 6-8 feet away from your roof to reduce access points.
Install Motion-Activated Lights and Sounds
Bright lights and noise can deter nocturnal animals like raccoons and skunks. Consider using motion-activated floodlights or ultrasonic repellents.
Keep Basements and Attics Well-Insulated
Ensure your home is properly insulated to reduce hiding spots and nesting areas. Store seasonal decorations and other clutter in sealed containers.
