Contrary to popular belief, hibernation is more than just a long nap. It’s a physiological state where an animal reduces its body temperature, metabolic rate, heart rate, and even breathing to conserve energy during periods of food scarcity and cold temperatures. While some mammals have developed this adaptation to survive winter, mice are not among them. So, how do mice manage to make it through the long, cold New England winters?
Do Mice Hibernate?
Mice do not hibernate. Instead, they remain active throughout the winter months, seeking ways to stay warm and find food. Their survival strategies include seeking shelter, huddling together for warmth, adapting physically to colder climates, and storing food.
Seeking Shelter
Without the ability to hibernate, mice require a warm, sheltered space to survive the winter. In the wild, this might be a hollow log, burrow, or woodpile. However, your home offers a much more comfortable option. With warmth, food, and protection from predators, it’s no wonder mice are drawn indoors during the colder months.
Huddling for Warmth
Mice are social creatures, and they use this to their advantage in winter. By huddling together, they can regulate their body temperatures more efficiently and conserve energy. This group behavior reduces the amount of heat each individual loses to the environment, helping them survive lower temperatures.
Physical Adaptations to the Cold
Over time, mice in colder climates like the northeastern United States have developed physical adaptations to help them withstand harsh winters:
- Larger Body Size: Mice from colder regions tend to be slightly larger than their warm-weather counterparts. A larger body mass allows for better heat production and retention.
- Thicker Fur: Some mice grow thicker coats during the winter months to provide additional insulation.
- Enhanced Nest Building: Mice build larger and more insulated nests using materials like shredded paper, fabric, and other soft items they find. While this helps them stay warm, it can lead to damage in your home as they chew through stored items for nesting materials.
Storing Food
By late fall, mice work diligently to build up a sizable food stash to last them through the winter. They hide food in various locations around their nests, known as “caches.” If you discover small piles of seeds, grains, pet food, or scraps in hidden areas of your home, it’s a strong indication of mouse activity.
Continuous Foraging
Even after accumulating a substantial food supply, mice continue to forage and hoard. This behavior ensures they have enough food even if some of their stores are discovered or spoiled. Unfortunately, this means they will persistently seek out and contaminate your food sources throughout the winter.
Are Mice Active in Your Home?
Since mice remain active year-round, an infestation won’t diminish over the winter. Your warm home with accessible food makes it an ideal environment for them. Here are some signs that mice may be sharing your space:
Signs of Mouse Activity
1. Chewed Food Packaging
Mice are resourceful and can chew through plastic and cardboard packaging to access food. Look for gnaw marks on:
- Bread bags
- Cereal boxes
- Dry goods stored in pantries
- Pet food bags
2. Droppings
Mouse droppings are a clear sign of infestation. Characteristics include:
- Size: Approximately 1/4 inch long
- Shape: Pointed ends, resembling a grain of rice
- Color: Fresh droppings are dark brown or black; they lighten to gray over time
- Quantity: Mice can produce up to 75 droppings per day
Check areas where food is stored, such as pantries, cupboards, drawers, and under sinks.
3. Urine Odor
Mice urinate frequently, leaving behind a strong, musky odor of ammonia. This smell becomes more noticeable as the infestation grows. You may also see yellow staining or crystallized urine deposits along their runways.
4. Noises
Being nocturnal, mice are most active at night. Listen for:
- Scratching or Scrabbling Sounds: In walls, ceilings, or under floorboards
- Gnawing Noises: Mice chew on wood, wiring, and other materials
- Squeaking: Vocalizations during social interactions
5. Nesting Materials
Mice build nests using shredded paper, fabric, insulation, and other soft materials. Finding these nests in hidden areas like attics, basements, or behind appliances is a sign of infestation.
6. Grease Marks and Tracks
Mice often travel the same routes along walls and baseboards, leaving behind greasy rub marks from their fur. You might also notice footprints or tail marks in dusty areas.
Protecting Your Home from Mice
Given the health risks and potential property damage caused by mice, it’s important to address an infestation promptly.
Prevention Tips
- Seal Entry Points: Mice can squeeze through openings as small as a dime. Inspect your home’s exterior for gaps or holes and seal them with steel wool and caulk.
- Store Food Properly: Keep food in airtight containers made of glass or metal. Don’t leave pet food out overnight.
- Reduce Clutter: Clutter provides hiding places for mice. Keep storage areas organized.
- Maintain Cleanliness: Regularly clean kitchens and dining areas to eliminate food crumbs and spills.
- Trim Vegetation: Keep shrubs and branches away from your home’s exterior to reduce access points.
