Rodents: Identification, Prevention & Control

Roof Rat   Norway Rat

Habitat and Identification

Rodents colonize in attics, burrows, under concrete and porches, in wall voids and other hard to reach places.

In Singapore, the most troublesome rats are two introduced species, the Roof rat and Norway rat. It’s important to know which species of rat is present in order to choose effective control strategies.

Recognizing Rat infestation

People don’t often see rats in his/her environment.
Rather, there are signs that indicate it’s presence, including:

  • Rodent droppings.
  • Unexplained chew marks.
  • Scratching or scampering noises.
  • Nesting materials found.
  • Damage to electrical wiring or plumbing.


Rodents can eat and contaminate foodstuffs and animal feed, while carrying a variety of diseases including: typhus, toxoplasmosis, trichinosis, Hanta virus, leptospirosis, salmonellosis (food poisoning), and ratbite fever.

They also act as hosts for fleas, mites, ringworms and tapeworms.
An infestation of rodents can also result in an infestation of these parasites. Although their gnawing can cause a great deal of property damage, typically the worst damage is the result of a contamination from feces and urine.

Prevention and Control

Good sanitation will effectively limit the number of rats that can survive in and around the home. This involves good housekeeping, proper storage and handling of food materials and refuse, and elimination of rodent shelter (harbourage). Removing clutter around homes allows inspection for signs of rats. Good sanitary practices will not eliminate rats under all conditions, but will make the environment less suitable for them to thrive.
