Are the Rats in My Roof Native?

- Roof rats (black rats) are an introduced species, highly adaptable to urban areas.

| Color | Variable (black, brown, grey) | More uniform natural tones |
| Habitat | Roofs, walls, urban homes | Bushland, water sources |
| Behavior | Nocturnal, aggressive | Less likely to infest homes |
Why Are Feral Rats a Problem?
