Brown Rats Distibution in Australia

Distribution of brown rats in Australia

The Norway/ Brown rat is the largest of the commensal rodents in Australia, with its distribution restricted to human coastal settlements.

The species is often found inhabiting warehoues, shipping ports and large urban settlements and, more than any other rodent specices, it has adapted to utilise human food and wastes. In Australia however, the specices has not been successful in colonising agricultural systems; only a few systems report minor damage due to brown rats.


Brown rats can be distinguished from other rattus specices by its size, small ears and thick tail which is usually shorter than its body. Its coatis variable like the roof rat, ranging from grey to brown above with a white or grey belly


Occasionally, albino and pure black individuals occur. Compared to the rood rat, the brown rat has a scruffy appearance and a very aggressive nature, not hesitating to attack when cornered.


Brown rats are poor climbers however, they can reach elevated areas if the correct structures are present to aid climbing

"We first used A1 Pest Control a few years ago when we noticed a few termites under a wine barrell in the rear yard of our home. We asked A1 Pest Control Sydney to pay us a visit to have a thorough termite inspection of our home. Bruce and his crew were on time, and very well presented. They explained how they would get rid of the termite infestation using a low toxic method and how their Thermal cameras worked, It worked very well and now we can sleep at night!"

"We have been using Bruce form A1 Pest Control for over 4 years now. We bought our new house on the Hills Area, and moved in. our neighbours had problem with rodents and spiders so they are using A1 next door. I asked them if they could come over and treat our house too, as i didn't want to chase pest around our home. The service was not only effective, but carried out without any smelly fumes that we have experienced in our last house. They solved problem next door and I haven't seen a bug since."

"A1 Pest Control exterminators where great! I'm very happy to say that they solved a bed bug problem that I had after we had visitors from overseas visit us. I would recommend A1 Pest Control to anyone needing a safe and effective treatment of bed bugs"
Amanda Wu
"Bruce solved our commercial pest control problem in Castle Hill. Cockroaches were throughout our factory and they were completely gone after two visits from his exterminators. Just seeing one cockroach can lose us clients. I know now everyhing is ok, and our reputation is intact"

"Bruce from A1 Help us get rid of a bad spider infestation that have been troubling us for a while. It was done with low toxic spray and his crew even game me some cockroach and ant baits to get rid of them. I have recommended A1 to all my friends and family"
