|RODENTS: 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.
