Which NYC Neighborhoods Have the Most Rats? (Data by Borough)

The short answer

NYC’s worst rat activity is concentrated in four Health Department Rat Mitigation Zones: the Grand Concourse in the Bronx; Bushwick, Bed-Stuy and Prospect Heights in Brooklyn; West, Central and East Harlem in Manhattan; and the East Village, Lower East Side and Chinatown downtown. Using the most reliable measure — DOH rat inspection failure rates — neighborhoods like Highbridge and Concourse fail about 47% of inspections, while Greenwich Village and SoHo fail only about 9%. But here’s the part most “rattiest neighborhood” lists miss: citywide, rats are in retreat. 311 rat sightings dropped roughly 20% in 2024, a decline the city attributes to mandatory trash containerization.

This is a reference page. Below we break down where the rats actually are, why the data says what it says, and what it means if your block is in a hotspot.

How NYC measures rats: complaints vs. inspections

There are two main public datasets, and they tell slightly different stories.

311 rat complaints are what New Yorkers report — about 40,000 rat-activity complaints a year, per NYC DOH. They’re useful but biased: a complaint reflects who picks up the phone, not just where rats live. An engaged Park Slope block may report more than a higher-burden block where residents have stopped bothering.

DOH rat inspections are the better signal. The Health Department conducts over 150,000 rat inspections a year, and inspectors record a pass or fail for active rat signs (droppings, burrows, gnaw marks) or rat-friendly conditions like open trash. Because inspectors visit systematically — block by block in targeted areas — the failure rate is a cleaner comparison between neighborhoods than raw complaints.

That distinction matters: when you see a neighborhood “ranked rattiest,” ask whether it’s by complaints (who reported) or by inspection failures (what inspectors actually found).

The four Rat Mitigation Zones (the real hotspots)

A Rat Mitigation Zone (RMZ) is the city’s highest-priority designation — an area with a heavy, persistent rat burden where DOH inspects entire blocks (“rat indexing”), supports owners, and coordinates agencies on public land. As of 2025, NYC DOH’s Rat Mitigation Zone Report lists four, covering tens of thousands of surveyed properties:

1. Bronx — Grand Concourse / Highbridge / Concourse

The Bronx’s Grand Concourse corridor is the city’s heaviest. In the Highbridge and Concourse area, 47.3% of inspected locations failed — the worst rate the DOH highlights. Initial-inspection failure rates here ran around 26–30% in the 2024–2025 reporting windows, and compliance re-inspection failure rates topped two-thirds. Dense pre-war apartment stock, steep topography with cellar access, and heavy street activity all feed the burden.

2. Brooklyn — Bushwick, Bed-Stuy & Prospect Heights

The Brooklyn RMZ centers on Bushwick and Bedford-Stuyvesant, extending into Prospect Heights. This zone saw real progress: 311 complaints in the Bed-Stuy/Bushwick area fell from 946 (Jan–June 2024) to 761 (Jan–June 2025), and initial-inspection failures dropped from about 27% to 18%. Brownstone blocks with shared rear yards and cellar connections make exclusion difficult — rats move building-to-building underground, which is exactly the dynamic we describe in how to get rid of rats in NYC.

3. Manhattan — West, Central & East Harlem

Harlem is the Manhattan stronghold. Combined 311 rodent complaints in the Harlem RMZ fell from about 2,301 (Jan–June 2024) to 2,133 (Jan–June 2025), with initial-inspection failures down from roughly 21% to 14%. Notably, compliance re-inspection failures in Harlem actually rose (around 66% to 77%), a reminder that “fewer complaints” doesn’t always mean “fully resolved.” Hell’s Kitchen and the Upper West Side, just south and west, saw complaint drops of about 34% and 19% respectively.

4. Lower Manhattan — East Village, Lower East Side & Chinatown

The downtown RMZ covers the East Village, Lower East Side and Chinatown — old tenement stock above some of the densest restaurant and food-retail corridors in the country. This zone bucked the trend slightly: initial-inspection failures ticked up from about 12% to 14%, though compliance re-inspection failures improved (around 62% to 51%). Restaurant-heavy blocks are perennial rat real estate, which is why food-service operators lean on restaurant pest control built around the NYC health code.

Where rats are least of a problem

The flip side of the data: parts of Manhattan with newer infrastructure, less street-level food waste, and well-managed buildings post low failure rates. Greenwich Village and SoHo failed only about 9% of inspections — roughly one-fifth the rate of Highbridge/Concourse. Lower density of older cellar-connected tenements, fewer uncontained trash piles, and more private sanitation contracts all help. It’s a useful benchmark: a 9% floor shows that in NYC, rat burden is driven by conditions you can change, not by some fixed citywide fate.

The bigger trend: NYC rats are declining

The headline most rat-ranking pages bury is that rats are losing ground citywide. NYC DSNY data shows 311 rat sightings fell from 25,230 (Dec 2023–Nov 2024) to 20,025 a year later — a 20.6% drop — with declines reported across many consecutive months. Across the four RMZs, combined complaints fell from about 4,194 to 3,956 in the Jan–June comparison.

The city credits trash containerization — “the Trash Revolution.” Set-out times moved to 8 p.m., and secure-bin requirements phased in for food businesses (2023), then all businesses (March 2024), with residential containerization expanding toward the June 2026 deadline. Rats live and die by accessible food; pull the open trash off the curb and the population contracts. That’s the same first principle behind professional rat & mouse control: remove the food and harborage, then knock down what’s left.

Why hotspots cluster where they do

The pattern isn’t random. Heavy-rat blocks share traits:

• Old, cellar-connected housing. Pre-war brownstones and tenements have shared basements and underground voids that let rats travel building-to-building — exclusion has to be done at the block level, not one unit at a time.
• Restaurant and bodega density. Food-service corridors generate constant organic waste. Downtown and Harlem hotspots overlap heavily with dining strips.
• Construction and aging infrastructure. Excavation and broken sub-grade utilities open new harborage and push rats to the surface.
• Subway-adjacent and park-adjacent blocks. Connected underground systems and green space give rats shelter and burrow sites near the buildings they feed in.

A real public-health stake

This isn’t only nuisance. Rats spread leptospirosis, a bacterial disease carried in their urine. NYC DOH health advisories reported 24 human cases in 2023 and about 33 in 2024 — record highs, versus an average of roughly 3 cases a year from 2001 to 2020. Cases cluster in warmer, wetter months, and the city links the rise partly to climate conditions that help the bacteria persist. It’s one more reason hotspot residents shouldn’t wait out an infestation.

What to do if your block is a hotspot

1. Check your address. Use the NYC Health Department’s Rat Information Portal (the Rat Map) to see inspection history by address or BBL, or pull the Rodent Inspection dataset on NYC Open Data.
2. Fix the food, then the holes. Secure trash in hard containers, clear clutter and overgrowth, then seal entry points the size of a quarter. See how to get rid of rats in NYC for the full sequence.
3. Think building and block, not unit. In RMZ-style housing, rats move underground between properties — coordinate with management and neighbors.
4. Bring in a pro for persistent activity. Our rat & mouse control finds and seals the entry points DIY misses and runs Department-of-Health-conscious programs for food-service clients. Want pricing first? See rat exterminator cost in NYC.
