7 Sneaky Signs of Mice in Your Home

signs of mouse infestation in Maryland

When it comes to unwelcome guests, few are as stealthy and unwelcome as mice. These tiny rodents can quietly infiltrate your living space, causing more than a startle. Recognizing the subtle signs of mice in your house is crucial for promptly addressing the infestation and preventing health risks and property damage.

7 Signs of a Mouse Infestation in Your House

1. Droppings Everywhere

One of the most obvious signs to tell if you have mice running around is if you notice droppings. Mouse droppings look like tiny, rod-shaped black pellets and are about the size of a grain of rice. Homeowners usually find them near food sources, in closets, cabinets, along baseboards, and other dark places. Inspect these areas in your home to see if you notice any droppings.

It’s essential to exercise caution and avoid direct contact, as mouse droppings can harbor harmful bacteria.


2. Foul Odor Lingering

You may smell a foul odor if there is a heavy mouse infestation or a nesting sight nearby. In addition to mice leaving little black droppings around the house, you may smell their urine. A mouse’s urine can be difficult to spot, but you’ll likely smell it. The urine’s smell can be pretty foul—almost like Ammonia. The source of an unexplained bad smell in your home could be several things, but one cause you should seriously consider is mice.


3. Scratching Sounds in the Night

House mice are nocturnal creatures, which means they’re most active at night. Pay attention to any scratching, scuffling, or pitter-patter sounds from the walls or ceilings once you turn off the lights. While mice are usually extremely quiet, this is one of the few instances you can hear them. These sounds could indicate mice are moving through your home, looking for food or nesting materials.


4. Grease Marks

Mice travel alongside walls, and because of this, they can leave marks on them. Mice become dirty due to how they travel. They have natural oils on their skin and fur, and they easily pick up grease on their fur. This grease that mice carry can then get on your wall as they run alongside it. A grease mark found on your wall from mice is usually small and black.


5. Nests

If you start to notice a collection of soft, various materials, you may have mice in your home. A mouse’s nest usually consists of what resources are available to them in your home. Mice seek out soft materials to make their nests, such as fabric, paper, string, or insulation. Their nests are often hidden in secluded places, such as behind appliances, within wall cavities, crawl spaces, or in attics.


6. Gnaw Marks

House mice have strong teeth and gnaw on various materials to keep them sharp. Mice love to nibble on human food, so if you find bags of cereal, pet food, or other pantry items with chew marks or tears, it’s a good indication that you have unwanted guests.

Look for gnaw marks on food packaging, furniture, wood, cardboard, plastic, or even electrical wires like phone chargers. These gnaw marks can damage your property and pose a fire hazard.


7. Odd Pet Behavior

Your pets are often the first to sense there’s something amiss in their territory. If your cat or dog is suddenly more alert, paws or sniffs at unusual places, or seems fixated on a particular area in your house, they might be onto the little critters. Trust your furry friend’s instincts; they could indicate signs of mice in your house that you haven’t detected yet.
