Roof rat
Rattus rattus
- Identification
- Slimmer than the Norway rat, dark, with a tail longer than its body and large ears. An agile climber that nests high.
- Lifecycle & behavior
- Prefers upper levels — attics, rafters, and trees. Breeds year-round in favorable conditions.
- When it's active in Central NY
- Uncommon this far north but occasionally encountered; more a concern to rule out than a widespread CNY pest. Any climbing rat activity warrants inspection.
- Risk & damage
- Contaminates food, gnaws wiring in attics and upper walls, and nests in insulation.
- Why DIY falls short
- Because roof rats travel high, ground-level traps miss them; control requires finding the elevated runways.
- How we treat it
- Inspection of elevated entry and travel routes, trapping in the right locations, and sealing roofline access.
Roof rat or Norway rat?
Roof rats are slim and agile with a pointed muzzle, large thin ears, and a tail longer than the head and body combined. Norway rats are stockier, blunt-nosed, small-eared, with a shorter tail. If something is moving overhead in an attic or along rafters, roof rat is worth considering; if the activity is in a basement, crawlspace, or ground burrow, Norway rat is far more likely.
The roof rat in Central New York
Roof rats are much less established in this region than Norway rats, and are uncommon in the Finger Lakes and Southern Tier. They favor warmer climates and coastal or port areas. Anything reported overhead in a Central New York attic is far more often a squirrel, a flying squirrel, or a bat than a roof rat.
That said, correct identification still matters, because the control approach differs. Roof rats travel high and are best intercepted along overhead routes; Norway rats travel low. Assuming the wrong species means placing everything in the wrong place.

Roof rat — common questions
Something is running in my attic. Is it a roof rat?
In Central New York, almost certainly not. Roof rats are uncommon in this region. Overhead activity here is far more often gray squirrels during daylight, flying squirrels after dark, or bats. Identifying which one matters, because bats have legal timing restrictions on exclusion.
