As the temperature drops, uninvited guests may view your home as the perfect winter retreat. Small critters like mice, squirrels, bats, and raccoons are experts at finding cozy nooks to ride out the chill. But don’t worry—keeping your home critter-free this winter is easier than you think. With a few simple steps, you can secure your space against these furry invaders and avoid the damage and mess they can bring.
Ready to critter-proof your home? Let’s get started!
Steps to Take Outside
Animals live outside and you would expect them to be there. However, you don’t want them nesting so close to your home that they may be tempted to venture inside.
- Trim landscaping. Keep shrubs close to the house well-trimmed so there are not places for them to build a home. Trim your trees so squirrels won’t be able to easily jump from there to your roof. Avoid using wood chips as mulch, as these make wonderful nesting material.
- Store firewood safely. Firewood can be a cozy hideout. Place logs at least 20 feet away from your house. Not only will that keep critters farther away, but the distance will also help protect against a fire risk. Keep the wood at least 18 inches off the ground to reduce the chance of rodents seeking shelter there.
- Remove food sources. Food is a major draw for animals. Place bird feeders away from your home and use squirrel guards to keep unwanted visitors out. Store food in sealed containers, and ensure garbage cans are securely closed and inaccessible.
- Secure decks and porches. The spaces beneath decks and porches are prime nesting spots. Look for signs of activity like gnawed wood, droppings, or burrow holes. Animals prefer dark, quiet areas, so deter them with a combination of radios, flashing lights, and apple cider vinegar-soaked rags. Once the critters leave, block openings with decorative lattice, burying the bottom edge to prevent reentry.
A note: Groundhogs who burrow under concrete slab, deck, porch are hibernators. You do not need to worry about them in the winter. They will not bother anything. However, during the springtime, you can use some of the above actions to get them to leave. Mylar windmills that move with the wind also will frighten them away.
Steps to Take in the Garage
Your garage is the midpoint between the outside and your house. Due to its proximity to your home, and the amount of stuff you probably store there, it could be inviting for critters.
- Seal openings. Garages offer shelter that is relatively warm, dry and protected from the elements. It’s no wonder critters want to be there. They don’t need a lot of space to get inside. Mice can enter in a ¼ inch gap. Check your garage for any openings. Caulk and fill in any cracks. Install a garage weather seal to close the gaps at the bottom of the doors.
- Clear the clutter. Critters do not like being out in the open. They are seeking cozy spaces where they can hide. This includes behind boxes, under shelves, beneath insulation, inside old tires, and so on. Remove any unnecessary boxes. Use plastic bins with tight lids so they can’t get inside. Raise items off the floor as a further deterrent.
- Eliminate food sources. Don’t keep trash or store food in your garage. Animals can smell a food source. If you must keep food in your garage, seal it in a container that will help prevent the scent from being detected.
- Insulate cavity walls. If your garage has cavity walls, you may find them make great homes for smaller animals such as mice. Consider filling them with a spray foam insulation. Not only will it help prevent critters from nesting there, but it will keep your garage warmer. Pro Tip: Choose a foam that includes rodent repellent.
Steps to Take in the Attic and Chimney
Both attics and chimneys are popular places for critters to nest. They are often easily accessible to the outside, and like garages, they offer protection from the outside elements. They also are generally dark and quiet, something critters enjoy.
- Check for signs of critters. Listen for noises. Look for droppings or urine stains and for damage such as chewed wood or ripped ventilation ducts. If you suspect that there are animals, take steps to remove them safely. Your local wildlife organization or a professional exterminator are good resources.
- Seal entry points. Animals enter your attic through small openings. The easiest way to check is to look during daylight, and see the places where light is coming in. Common spots are by attic vents, and openings in your roof soffits or eaves. Take steps to seal those openings. For attic vents, put a screen to cover the entire vent using ½ inch mesh. Use gutter guards on your roof to keep critters from settling there.
- Install chimney covers. These mesh screens allow airflow while blocking access to birds, squirrels, bats and other animals. In addition, make sure your chimney damper is properly closed when you’re not using your fireplace.
Steps to Take Inside
Your home is a warm, comfortable sanctuary for you, but it can also be an inviting retreat for unwelcome critters. With countless hiding spots, from behind your walls to under your cabinets, pests can easily find cozy nooks. The key to keeping them out is vigilance and preparation.
- Inspect every room. Conduct a room-by-room inspection to identify potential entry points. Focus on areas where gaps might exist along your floors, under cabinets, or around doors. Pay close attention to places where wires, pipes, or vents penetrate walls; even a tiny ¼-inch gap is enough for a mouse to slip through. Use caulk or sealant to close these gaps and consider plugging larger holes with steel wool, as rodents find it difficult to chew through.
- Secure doors and windows. Install or upgrade weather stripping around your doors and windows to seal off any openings. For exterior doors, consider adding a sweep or brush strip to block even the smallest gaps at the bottom. These simple steps help keep pests—and drafts—out.
- Examine vents and exhausts. Check your dryer vent, stove exhaust vent, and other external openings. Birds and small animals often see these as perfect nesting spots. Install vent covers or screens to prevent intrusions while maintaining proper airflow.
- Store food properly. Avoid leaving food out in the open, including pet food. Store all pantry items in sealed, airtight containers. This not only deters pests but also keeps your food fresher for longer.
- Try natural deterrents. Use the power of scent to repel pests naturally. Peppermint oil, for instance, is a proven deterrent for mice. Soak cotton balls in essential oil and place them near suspected entry points or in areas prone to critter activity. Replace them regularly to maintain their potency.
Your home is your greatest investment. Keep up with winter home maintenance and protect your home with the right insurance for added peace of mind.
