1. Droppings

Rodent droppings are one of the most visible signs of an infestation. According to the Centers for Disease Control and Prevention (CDC), rodent feces can carry harmful diseases like Hantavirus and Salmonella. Droppings are often found in kitchens, pantries, and attics. If you spot small, dark, pellet-like droppings, it’s a clear indicator you may have unwanted guests.

2. Gnaw Marks

Mice and rats are notorious for chewing through wood, wires, and even plastic. This gnawing habit is not just destructive—it’s also a fire hazard. Tim explains, “I’ve seen rats chew through electrical wiring in subway tunnels; the same can happen in your attic.” Look for fresh gnaw marks that are lighter in color.

3. Strange Noises

If you hear scratching, scurrying, or gnawing in your walls or ceiling, it’s likely not your imagination. Rodents are nocturnal and most active during the night. Pay special attention to sounds coming from attics, basements, and inside walls.

4. Nests

Rodents build nests out of shredded paper, fabric, and other soft materials. You might find these nests hidden in dark corners, attics, or crawl spaces. Finding a nest is a strong indication of a growing population.

5. Grease Marks

Rodents often leave grease marks along walls and baseboards as they travel the same paths repeatedly. These smudges are from their oily fur rubbing against surfaces. If you spot greasy streaks, it’s a sign their paths are well-worn.

6. Footprints and Tail Marks

You might notice small footprints and drag lines from their tails in dusty or undisturbed areas. A simple way to confirm activity is to sprinkle a bit of flour or talcum powder along suspected paths and check for tracks the next day.

8. Holes And Entry Points

Rodents can squeeze through holes the size of a dime. Tim notes, “In New York, we always checked for even the smallest cracks, because that’s all it takes.” Inspect your home’s exterior and interior for potential entry points. Common areas include basements, attics, and crawl spaces.

10. Sightings

The most undeniable sign is, of course, actually seeing a mouse or rat. If you spot one, chances are there are more. Rodents are social creatures that breed quickly, so a single sighting should not be ignored.
