Black Rat in Melbourne — Quick Answer
The black rat, also known as the ship rat, is a common pest in Melbourne that nests above ground in roof voids and dense vegetation. Adults weigh 120–200 grams with sleek dark fur, large ears, and a tail longer than the body. They are skilled climbers that contaminate food and carry diseases. T47 Pest Control offers professional trapping and baiting programs tailored to eliminate black rat infestations in Melbourne homes.

Look-Alikes & Confusion Notes
The black rat is sometimes confused with the Norway rat. Key differences: black rats are sleeker, have larger ears, and a tail longer than the body. They prefer elevated nesting whereas Norway rats are ground-dwellers.
Risk & Urgency
High. Black rats spread salmonella, leptospirosis, and murine typhus. They gnaw electrical wiring (fire risk) and contaminate stored food. Prompt professional treatment prevents colony expansion.
Where Found in Melbourne
Black rats thrive in Melbourne suburbs with mature trees and dense gardens. They are particularly common near ports, waterways, and older commercial precincts. Inner-city terrace houses with roof voids are frequently affected.
What to Do Now
Clear dense vegetation from walls, secure roof entry points with metal mesh, and remove fallen fruit. Professional treatment from T47 Pest Control combines targeted baiting with exclusion work to resolve the problem quickly.
