Rats are part of New York's folklore, but a rat in your kitchen or a mouse behind the stove is a personal problem, not a legend. The city's mix of old masonry, shared walls, curbside trash and below-ground infrastructure gives rodents everything they need, and they are rarely more than a short run from a way inside.
The two main culprits
The Norway rat is the one most New Yorkers see. It burrows beside foundations, under sidewalk slabs, in garden beds and along the rear lots of rowhouses in neighborhoods like Bedford-Stuyvesant, the Lower East Side, Harlem and the South Bronx. Roof rats are far less common here. The house mouse, meanwhile, lives indoors, nesting in wall voids and behind appliances in apartments of every kind, from Astoria walkups to Midtown high-rises.
What the signs look like
- Droppings: rat droppings are larger than a grain of rice; mouse droppings are closer to a grain of rice and pointed.
- Greasy rub marks along baseboards and pipe chases.
- Scratching in ceilings or walls at night.
- Gnawed food packaging or chewed wiring.
- Burrow holes against building foundations, in tree pits or beneath stoops.
How professionals approach a New York job
Good rodent work starts with finding how they get in. A technician will check where pipes enter, gaps beneath doors, boiler-room openings, deteriorated brick pointing, vents and the garbage storage area. In multi-unit buildings they often examine the basement, compactor room and exterior alleys before looking at the apartment itself.
The treatment usually combines exclusion (steel wool, metal mesh, sealant and door sweeps), trapping, and carefully placed tamper-resistant bait stations outdoors. Poison alone rarely fixes it; if holes stay open, new rodents arrive. Providers also advise on sanitation, since a mouse needs only a small crumb trail to stay.
Building-level habits that matter
- Store household trash in lidded containers and put it out as close to pickup time as the rules allow.
- Close gaps around radiator pipes, under sinks and behind stoves.
- Keep food in sealed containers, including pet food overnight.
- Report burrows and overflowing bins to building management or the proper city channel.
- Trim vegetation and clear debris from rear yards and areas below fire escapes.
When to bring in a pro
One mouse in a closet may be a DIY job. Multiple sightings, activity in daylight, noises inside walls, or any burrow near a foundation call for a licensed provider. Rodents can gnaw wiring, which is a real fire concern in older buildings, and they can contaminate food storage.

Rodent questions from New York residents
How do I know if it is a rat or a mouse?
Size and droppings are the clearest clues. Rats leave larger droppings and make bigger gnaw marks, and are more likely to burrow outdoors. Mice stay mostly indoors.
Are rats more active in a particular season?
Rats are active year round, but cold weather pushes both rats and mice toward heated basements and apartments, so fall and winter calls climb.
Will traps alone fix the problem?
Not by themselves. Without sealing entry points, more rodents tend to replace those you catch.
Is it my landlord's job to deal with this?
In most rentals, building-wide rodent control sits with the owner or management. Report it in writing and keep a record of sightings.
