Apartment Rodent Control in NYC
In an apartment building, the mouse in your kitchen may have come from the basement, the trash room or the unit next door.
Short answerApartment rodent control looks at your unit and the building around it. Mice use wall voids, pipe chases and risers, so lasting results usually need the owner or manager involved as well as work inside your apartment.
Why Apartments Are Different
Shared walls, shared plumbing and shared trash areas give rodents routes between units. Treating one apartment alone can push activity next door and back again. Openings around pipes under sinks, behind stoves and in bathrooms are the usual routes inside a unit.

Apartment Buildings
A mouse in one unit can trace back to the basement, the trash room or the wall shared with a neighbor, so an apartment building inspection looks well past your own front door.
Renters: Start With the Owner
In most NYC rentals the owner is responsible for pests. In buildings with three or more apartments, Local Law 55 requires owners to inspect for pests annually and respond to complaints. Write to the landlord or managing agent, keep a dated copy, and use 311 if needed. This is general information, not legal advice. Read the tenant guide.
What an Inspection Covers
Kitchen and bathroom pipe openings, behind appliances, baseboards and cabinets, doors and closets, plus any access to common areas such as basements and trash rooms.

Questions and Answers
Why are mice getting into my apartment?
Mice need very little: a gap about the width of a pencil, a little food and a quiet place to nest. In apartment buildings they travel through wall voids, pipe sleeves and shared utility chases, so the opening may be in a neighbor's unit or the basement rather than yours. Finding the route matters more than adding more traps.
Why do mice move between apartments?
Attached buildings share wall voids, pipe chases, risers, trash areas and basements. Mice use those as travel routes, so treating one unit can push activity next door and back again. Lasting results in multifamily buildings usually depend on inspecting common areas and coordinating with the owner or manager, not treating a single apartment in isolation.
Who handles rats or mice in a NYC rental?
In most NYC rentals the owner is responsible. City rules require property owners to keep buildings free of rats, and owners of buildings with three or more apartments must also address pests inside apartments under Local Law 55. Tell the landlord or managing agent in writing, keep a copy, and use 311 if nothing happens. This is general information, not legal advice.
Should a tenant call 311 or the landlord first?
Start with the landlord or managing agent, in writing, and keep a dated copy. That creates a record and gives the owner a chance to act. If the owner does not respond, or the problem is severe, report it through 311. You can report rats or mice and the conditions that attract them.
