Common General Name:
The most common names are mouse and rat.
Interesting General Fact:
A rodent’s front incisor teeth never stop growing. They must constantly gnaw on hard materials like wood, plastic, and even electrical wiring to wear their teeth down. This relentless gnawing is a major reason they cause so much structural and property damage.

Specific Rodent Species:
House Mouse (Mus musculus):
Small and slender, typically greyish-brown, with excellent climbing abilities. Can squeeze through openings as small as a dime. The most common indoor rodent pest, reproducing quickly and nesting in secluded areas such as wall voids, attics, and storage boxes.
Norway Rat (Rattus norvegicus):
Also known as the brown rat or sewer rat. Large and robust with a blunt snout and thick tail shorter than its body. Skilled burrowers, often found in basements, crawl spaces, and sewers.
Roof Rat (Rattus rattus):
Also known as the black rat. More slender than the Norway rat, with large ears, a pointed snout, and a tail longer than its head and body combined. Excellent climbers, nesting in upper areas such as attics, ceilings, and trees.
Identifying a Rodent Infestation:
Early detection is key to preventing damage and health risks. Common signs of a rodent problem include:
- Droppings — small, dark, and pellet-shaped.
- Gnaw Marks — on wood, wires, food packaging, and furniture.
- Nests — shredded paper, fabric, or insulation tucked away in hidden areas.
- Scratching Noises — particularly at night, from walls, ceilings, or under floors.
- Grease Marks — dark, greasy smears along walls or baseboards from repeated contact with rodent fur.
- Tracks or Footprints — especially in dusty or rarely disturbed areas.
If you spot any of these signs, professional pest control is recommended to remove the infestation quickly and prevent further damage.
