Every time a New Yorker reports a rat to 311, it becomes a public record. We pulled those rodent-complaint records from NYC Open Data and ranked the city — by borough and by ZIP code — to map where rats are reported most. I’m Jorge Bedoya, an Associate Certified Entomologist (ACE); below the data, I’ll explain what actually drives these patterns and what it means for your home or building.

Rat complaints by borough
Brooklyn accounts for the most rodent complaints of any borough — more than Manhattan and roughly as many as Queens and the Bronx combined. Staten Island, with its lower density and more detached housing, sits far below the rest.

Methodology: rodent (rat & mouse) complaints filed with NYC 311 and published via the NYC Open Data Service Requests dataset. Figures reflect total complaints on record by borough and ZIP code.
What an entomologist sees in this data
These rankings aren’t random — they trace the city’s oldest, densest housing. The leaders share the same ingredients: aging sewer and water infrastructure, dense pre-war and brownstone building stock with countless gaps and shared walls, heavy foot traffic and food waste, and ongoing construction that displaces established colonies. East Harlem, central Brooklyn (Bed-Stuy, Crown Heights, Bushwick, Flatbush), and the Upper West Side check every box.
It’s also worth saying plainly: a high complaint count is not a sign that residents are doing anything wrong. Norway rats (Rattus norvegicus) follow infrastructure and food, not housekeeping. In neighborhoods like Ridgewood, Norwood, and Highbridge, the fix is the same one we use everywhere: find the entry points and seal the building, rather than just baiting.
What this means for your home or building
If you live or own property in one of these areas, treat rodent pressure as a constant to be managed, not a one-time event. The durable solution is exclusion — sealing the gaps rats use to get in (a rat needs only a quarter-inch) with metal mesh and hardware cloth — combined with monitoring and, where appropriate, burrow treatment. Bait alone never solves a rodent problem; it just refills. See our rat & mouse exclusion service, and the borough pages for Brooklyn, Manhattan, and the Bronx.
ACE-certified exclusion that seals rodents out for good — not just bait. Same-day across NYC.
