New York's rat is, with rare exception, the Norway rat — a bulky, ground-dwelling burrower, not the climbing roof rat found in warmer coastal cities. Norway rats burrow into soil along foundations, in tree pits, garden beds and under decking, and they travel through connected basements, subway-adjacent conduits and shared trash areas. That means a rat problem is rarely confined to one building — it's a block-level pressure pattern, and treating one property in isolation without addressing the burrows and food sources around it is a short-term fix at best.
The single hardest thing about rat control that separates it from mice is behaviour: Norway rats are highly neophobic. A new bait station, trap, or even a fresh patch of cement placed in an active run will be avoided for two to three days before the colony resumes normal movement around it. Rush a rat job — checking bait after 48 hours and declaring it a failure — and you haven't actually given the treatment a chance to work. Our programme accounts for this: exterior tamper-resistant bait stations placed on confirmed runways and at burrow entrances, checked and replenished on a weekly cycle, not a single drive-by visit.
Exclusion and sanitation are just as important as the bait itself. We seal foundation gaps, basement bulkhead doors and utility penetrations with steel mesh and hydraulic cement — materials a rat can't gnaw through — and we flag the sanitation conditions (uncontained trash, cracked bins, open compost staging) that keep drawing rats back to a block regardless of how many are removed. Rat control that skips this step sees the population rebound from the adjacent colony within one breeding cycle.
How much does rat extermination cost in NYC?
$200–$1,200
One-time baiting: $200–$500. Exclusion (baiting + entry-point sealing): $400–$900. Ongoing monitoring: $100–$200/month. NYC per-treatment overall: $300–$1,200 (avg ~$475). National per-visit average: $345 (range $216–$495).

Market range — not our quote
This is a market range synthesised from published cost guides — not a quote from this provider. The actual price depends on an in-person or photo-based inspection.
Angi's $345 average (range $216–$495) is the only tier-1, NYC-geo-targeted figure found and is notably lower than the tier-2 NYC blogs' $300–$1,200 claim. Both are shown — do not collapse into a single misleadingly precise number.
What drives the price
- Baiting-only vs full exclusion (sealing entry points)
- Number of visits needed for heavy infestation (3–5 visits can total $700–$1,500)
- Building type / density
- Ongoing monitoring plan vs one-off
Signs you have a rat extermination problem
- Burrow holes (2–4 inches across) in soil along foundations, garden beds, tree pits, or under sheds and decking
- Large, blunt, capsule-shaped droppings (up to 18mm) near trash areas, basement walls, or burrow entrances
- Dark, greasy rub marks low along foundation walls and pipe chases where rats travel repeatedly
- Heavy gnaw marks on wood, soft concrete, or plastic piping — larger and rougher than mouse damage
- Scurrying or scratching sounds low down — in the cellar, crawl space, or immediately outside at night
Why New York sees this
Norway rats need a gap of about half an inch to get in — roughly the size of a quarter — so exclusion for rats targets foundation cracks, weep holes and basement bulkhead doors, larger openings than the dime-sized gaps mice use.
NYC's mandatory curbside organics (compost) collection concentrates food odour at the same kerb location every week, which has measurably densified rat foraging and burrow activity near regular bin-staging points on many residential blocks — we check the kerb line at both ends of a block as part of any exterior inspection.
Buildings inside a NYC Health Department Rat Mitigation Zone can be indexed and inspected as part of a neighbourhood-wide effort; active rat signs or uncontained trash on your property can still trigger a violation even while the city runs public-land baiting nearby — private property remediation remains the owner's responsibility either way.
Because rats are neophobic, effective treatment takes a minimum of several visits over two to three weeks — a single-visit rat job with no follow-up rarely holds.
