Since 2006, our licensed technicians have inspected building envelopes across all five boroughs — foundations, pipe penetrations, door sweeps, utility chases — because that's where a rodent job actually gets decided, long before the first bait station goes down. Skipping that step is the single most common reason a previous provider's treatment didn't hold.
New York's rat is a burrower, not a climber — the Norway rat nests in soil, along foundations, and in tree pits, not attics. Mice, in contrast, travel through shared risers and wall voids in multi-family buildings. Diagnosing which one you have, and how it's moving through the building, is what separates a licensed exterminator's approach from a generic bait-and-hope service call.
We seal every entry point with rodent-proof materials sized to the actual gap, then knock down the active population with trapping and tamper-resistant bait placed away from children and pets — documented at every visit, which matters for landlords and property managers facing NYC Department of Health inspection standards.
What actually keeps rats and mice out of a New York City apartment?
Sealing entry points is the foundation of rodent control: the CDC notes a mouse can fit through a hole the width of a pencil — about 1/4 inch or 6 millimeters across — so even gaps that look far too small for a rodent are enough to let mice in. Trapping or baiting without sealing these openings only treats the symptom. (CDC — Seal Up to Prevent Rodents)
In New York City, property owners are legally required to keep rats out of homes. The Health Department designates Rat Mitigation Zones — areas of high rat activity where City agencies concentrate resources — and lets residents report a rodent problem online through 311 to trigger an inspection. (NYC Health — Rats)
The US EPA's prevention guidance is to deny rodents food, water and shelter, then seal holes inside and outside the home to keep them out — something as simple as plugging small openings with steel wool or patching holes in interior and exterior walls. Removing nesting sites such as leaf piles and deep mulch removes the harborage rodents depend on. (US EPA — Identify and Prevent Rodent Infestations)
Mice and rats are recognized indoor asthma triggers, not just a nuisance: NYC Housing Preservation & Development lists mice and rats among the common allergens that can cause or worsen asthma, and under Local Law 55 of 2018 owners of buildings with three or more apartments must keep tenants' units free of pests and the conditions that attract them. (NYC HPD — Indoor Allergen Hazards (Mold and Pests))
Trapping vs baiting vs exclusion — what's the right rodent strategy?
| Snap trapping | Rodenticide baiting | Exclusion / sealing | |
|---|---|---|---|
| Where the rodent ends up | In the trap — easy to find and remove | Often inside walls or voids, out of sight | Kept outside before it ever enters |
| Secondary-poisoning risk to pets and wildlife | None | Possible if a poisoned rodent is eaten | None |
| Closes the entry point | No — new rodents can re-enter | No — new rodents can re-enter | Yes — pencil-width gaps sealed per CDC guidance |
| Best role | Knock down an active indoor population | Reduce numbers where trapping is impractical | Permanent prevention; pairs with any method |
How much does rat & mouse control 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 rodent control problem
- Droppings along walls, under sinks, or in cabinets and drawers
- Gnaw marks on food packaging, wiring, or baseboards
- Scratching or scurrying in walls or ceilings, especially at night
- A persistent musky, ammonia-like odour
- Greasy rub marks along baseboards where rodents travel the same route repeatedly
Why NYC sees this
Twenty years of rodent calls across every borough means we've seen the entry-point pattern in pre-war walk-ups, brownstones, and post-war high-rises — the diagnosis differs by building type, and our licence covers all of them.
For landlords and co-op boards, our documented exclusion-and-treatment record is built to satisfy NYC Department of Health inspection standards, not just quiet the immediate complaint.
