You wouldn’t believe the places rodents can sneak into. From break rooms to ceiling spaces and wall voids, rats and mice are great at finding those hidden spots in your building where they can get food, water, and shelter. They can slip through openings that seem way too small to fit.
While these little scavengers might know how to stay hidden, they’re not exactly clean, so spotting the mess they leave behind is usually pretty easy.

Why Rodents Are a Problem
Rodents are more than just a nuisance—they pose serious threats:
- Health risks: Rodents can carry diseases such as hantavirus, leptospirosis, and salmonella.
- Structural damage: Their constant gnawing can destroy wiring, insulation, and woodwork, increasing the risk of electrical fires.
- Food contamination: Rodents can ruin food supplies by chewing through packaging and leaving droppings.
Understanding the signs of an infestation can help you act quickly to prevent these issues from escalating.
8 Key Signs of a Rodent Infestation
1. Droppings
Rodent droppings are one of the most telltale signs of an infestation.
- Appearance: Droppings are small, dark, and pellet-shaped.
- Locations: Common areas include kitchen cupboards, pantries, under sinks, and along baseboards.
Regularly inspect these spaces for fresh droppings, as they indicate active rodent presence.
2. Gnaw Marks and Damage
Rodents have ever-growing incisors, so they constantly gnaw to keep them in check.
- Chewed materials: Look for gnaw marks on wood, electrical wiring, plastic, and cardboard.
- Food packaging: Rodents will chew through boxes and bags to access food.
If you notice bite marks or damaged goods, it’s a sign rodents are active in your space.
3. Nests and Nesting Materials
Rodents create nests in hidden areas using soft materials.
- Common materials: Shredded paper, fabric, insulation, and dried plants.
- Locations: Nests are often found in dark, undisturbed areas such as attics, basements, or behind appliances.
Spotting nests or finding scattered nesting materials clearly indicates an infestation.
4. Unusual Noises
Rodents are most active at night, making noise as they scurry or gnaw.
- Types of noises: Scratching, squeaking, or scampering sounds.
- Locations: Listen for noises in walls, ceilings, and under floors.
If you hear these sounds, it’s likely rodents are present.
5. Tracks and Smudge Marks
Rodents leave behind evidence as they travel along their established routes.
- Tracks: Look for small footprints or tail marks in dusty areas.
- Smudge marks: Rodents rub against walls, leaving greasy streaks.
Use a flashlight to inspect hard-to-see areas for these signs.
6. Unpleasant Odours
A strong, musky smell is often associated with rodents.
- Urine odour: Rodent urine has a pungent smell and can linger.
- Decomposing rodents: If a rodent dies in your home, it will emit a foul odour as it decomposes.
Pay attention to unusual smells, especially in enclosed spaces like cupboards or crawlspaces.
7. Pet Behavior Changes
Pets are often the first to detect a rodent infestation.
- Increased interest: Dogs or cats may sniff or paw at specific areas.
- Agitation: Pets may appear restless or overly alert, especially at night.
Monitor your pet’s behaviour for signs of heightened awareness or distress.
8. Rodent Sightings
Physically seeing a rodent is a definitive sign of an infestation.
- Daytime sightings: Seeing a rodent during the day often indicates a significant infestation.
- Dead rodents: Finding dead rodents can also signal an ongoing problem.
Don’t dismiss sightings as isolated incidents; they often point to a larger issue.
What to Do If You Spot These Signs
Step 1: Inspect Your Property
Conduct a thorough inspection to confirm the extent of the infestation.
- Check common hiding spots such as attics, basements, and behind appliances.
- Look for entry points like gaps in walls, vents, or doors.
Step 2: Seal Entry Points
Prevent rodents from entering by sealing gaps and cracks.
- Use steel wool, caulk, or metal mesh to block holes.
- Ensure doors and windows close tightly, and install door sweeps if necessary.
Step 3: Remove Food and Water Sources
Rodents are attracted to easily accessible food and water.
- Store food in airtight containers.
- Clean up crumbs and spills promptly.
- Fix leaks to eliminate water sources.
Step 4: Set Traps
Traps can help control the rodent population.
- Types of traps: Snap traps, glue traps, and live traps.
- Placement: Set traps along walls, near nests, and in areas where droppings are found.
Step 5: Contact a Professional Pest Control Service
For severe infestations, it’s best to seek expert help.
- Professionals can identify the source of the infestation and implement targeted solutions.
- They use safe and effective methods to eliminate rodents and prevent recurrence.
Preventing Future Infestations

Why Fast Action Matters
Ignoring a rodent infestation can lead to serious consequences:
- Rapid breeding: Rodents reproduce quickly, making infestations harder to control over time.
- Health hazards: Delayed action increases the risk of disease transmission.
- Costly damage: Structural repairs and replacements can become expensive.
Acting swiftly ensures the safety and integrity of your property.
