Norway rat
Rattus norvegicus
- Identification
- Large and heavy-bodied (7–9 inches plus tail), brown with a blunt nose and small ears. Droppings are capsule-shaped, up to ¾ inch.
- Lifecycle & behavior
- Ground-burrowing; lives in and around foundations, sewers, and outbuildings. Breeds prolifically, with several litters a year.
- When it's active in Central NY
- Less common than mice in most of CNY but present, especially near water, farms, and older urban areas. Pressure rises in fall as they seek shelter and food.
- Risk & damage
- Gnaw structural materials and wiring, contaminate food, and can transmit disease. Their burrowing undermines slabs, steps, and foundations.
- Why DIY falls short
- Rats are neophobic (wary of new objects), so trapping requires the right placement and patience, and burrows must be addressed outside.
- How we treat it
- A structured trapping and baiting program plus exclusion and burrow management, with heavy-duty sealing materials rats can't gnaw through.
Norway rat or roof rat?
In Central New York this is usually an easy call, because the Norway rat is the one you have. It is heavy-bodied and blunt-nosed with small ears and a thick tail shorter than its body. A roof rat is slimmer, with a pointed muzzle, large ears, and a tail longer than its body. The behavioral difference is even clearer: Norway rats burrow and stay low — basements, crawlspaces, slab edges, and ground burrows — while roof rats climb and prefer attics and upper stories.
The Norway rat in Central New York
Norway rats concentrate where food waste concentrates: downtown commercial blocks with shared alleys and dumpsters, restaurant loading areas, and older neighborhoods adjacent to them. That is why rat pressure in Ithaca and Elmira follows the commercial cores and the residential streets immediately around them rather than being spread evenly across the city.
Because they burrow, exterior evidence often precedes interior evidence. Smooth, greasy runways along foundations, burrow openings at the base of walls or under slabs and steps, and gnawing at low entry points usually appear before anyone sees a rat indoors. Catching it at that stage is dramatically easier.

Norway rat — common questions
Do we have rats in Ithaca, or just mice?
Both. Norway rats are established here, concentrated around downtown commercial areas, shared alleys, and dumpster corridors, and in the older residential blocks next to them. They are far less widespread than mice but considerably harder to remove once settled.
What is the first sign of a rat problem outdoors?
Burrow openings at the base of a foundation, under steps, or beside a slab, plus smooth darkened runways where they travel repeatedly. Exterior signs typically show up before anything is seen inside.
