Dealing with a rodent infestation can be a frustrating and unsettling experience. Identifying the type of rodent causing the problem is essential for effective pest control.

In this blog post, we’ll guide you through the process of identifying the type of rodent problem you have and provide insights on how to address it. By understanding the signs and behaviour of different rodents, you can take the necessary steps to eliminate the infestation and prevent future occurrences.

Mouse Infestation:

Mice are common household pests known for their small size and rapid reproduction. Here’s how to identify a mouse infestation:

  • Droppings: Mouse droppings are small, resembling tiny grains of rice. You may find them near food sources or along commonly traveled routes.
  • Gnaw Marks: Mice have a constant need to chew, resulting in gnaw marks on various materials such as food packaging, electrical wires, or furniture.
  • Squeaking or Scratching Noises: Mice are nocturnal creatures, so you may hear high-pitched squeaking or scratching sounds, particularly at night.
  • Nests: Mice build nests with shredded materials like paper, fabric, or insulation. Look for hidden nests in dark, secluded areas such as wall voids or cabinets.
  • Sightings: Spotting live mice is a clear indication of an infestation. Mice are quick and agile, so they can scurry out of sight quickly.

To tackle a mouse infestation, seal off entry points, set traps, and practice good sanitation to eliminate their food sources.

Rat Infestation:

Rats are larger rodents that can cause significant damage and pose health risks. Here’s how to identify a rat infestation:

  • Larger Droppings: Rat droppings are larger than mouse droppings and have a tapered shape. They are usually found in concentrated areas, such as near food or nesting sites.
  • Gnaw Marks: Rats have strong teeth that leave noticeable gnaw marks on wood, plastic, or electrical wires. Look for fresh chew marks as an indication of recent activity.
  • Strong Odour: Rats emit a distinctive musky odour. This is as a result of a prolonged infestation, in combination with their urine which emits a foul odour. If you notice a foul smell in certain areas of your property, it could be a sign of a rat infestation.
  • Burrows and Runways: Rats dig burrows and create well-worn pathways along walls, fences, or vegetation. Look for these runways, especially in outdoor areas.
  • Sightings: Rats are more cautious and tend to stay hidden. If you see a rat during daylight hours, it could indicate a significant infestation.

To address a rat infestation, it’s important to block entry points, eliminate food and water sources, and use traps or seek professional assistance for effective eradication.


Identifying the type of rodent infestation you have is crucial for implementing the right pest control measures. By paying attention to the specific signs of mouse or rat activity, such as droppings, gnaw marks, noises, nests, and sightings, you can take appropriate steps to eliminate the infestation and prevent future rodent problems. If the infestation persists or you’re unsure about handling it on your own, it’s best to consult with a professional pest control company, like Flick Pest Control for expert guidance and assistance in resolving the issue effectively.
