As temperatures drop across Northeast Ohio, mice start looking for warm places to spend the winter—and your Cleveland home is an inviting target. These small rodents can squeeze through openings as small as a dime, making even well-maintained homes vulnerable.
Catching a mouse problem early is crucial. A single pair of mice can produce up to 60 offspring in a year, turning a minor issue into a full-blown infestation quickly. Here are five signs every Cleveland homeowner should know.
1. Droppings
Mouse droppings are the most common sign of an infestation. They’re small (about 1/4 inch), dark, and pointed at both ends. You’ll typically find them:
- Along walls and baseboards
- Inside cabinets and drawers
- Near food sources in the kitchen or pantry
- In basement corners and storage areas
Fresh droppings are dark and moist, while older ones are gray and crumbly. If you’re finding fresh droppings regularly, mice are actively present.
2. Gnaw Marks
Mice have teeth that never stop growing, so they gnaw constantly. Look for:
- Chew marks on food packaging (cardboard boxes, plastic bags)
- Gnawed edges on wooden furniture or baseboards
- Damaged electrical wires (a serious fire hazard)
- Holes in walls, especially near pipes or utility lines
New gnaw marks are lighter in color and darken with age. If you notice both old and new marks, you likely have an ongoing problem.
3. Scratching Sounds
Mice are most active at night. Listen for:
- Scratching or scurrying sounds in walls
- Rustling in the attic or ceiling
- Squeaking noises, especially during quiet hours
If you’re hearing these sounds regularly, mice have likely established nesting sites in your home.
4. Nesting Materials
Mice build nests using whatever soft materials they can find:
- Shredded paper or cardboard
- Fabric scraps or insulation
- Dried plant material
Check hidden areas like behind appliances, in storage boxes, and in rarely-used closets. Finding a nest means mice are breeding in your home.
5. Grease Marks and Runways
Mice follow the same paths repeatedly, leaving behind:
- Dark, greasy rub marks along walls and baseboards
- Visible “runways” in dusty areas
- Footprints in dust or powder
These marks indicate established travel routes and can help identify entry points.
What to Do If You Spot These Signs
If you notice any of these signs, don’t wait. Mice populations grow quickly, and they can cause significant damage to your home while contaminating food and spreading disease.
Steps you can take immediately:
- Store food in airtight containers
- Seal obvious entry points with steel wool and caulk
- Remove clutter that provides hiding spots
- Keep outdoor areas clean of debris and woodpiles
When to call a professional:
While DIY methods can help with prevention, established infestations require professional treatment. Mice are clever and trap-shy, and store-bought solutions often fail to address the full scope of the problem.
