The first question almost every homeowner asks is: what is this going to cost me? It is a fair question. Pest control pricing is not posted on a menu board, and the range is genuinely wide. A routine ant treatment and a full termite remediation live in completely different pricing universes.
This guide breaks down what professional exterminator services actually cost in Westchester County in 2026. You will see real price ranges by pest type, the factors that push prices up or down, how service plans compare to one-time treatments, and how to tell whether a quote is reasonable or inflated.
Quick Cost Estimator
Average Exterminator Costs by Pest Type
These ranges reflect what licensed Westchester County companies charge in 2026. National averages often run lower because they include lower cost-of-living markets. Expect the ranges below to be more accurate for Scarsdale, White Plains, Yonkers, and surrounding communities.
| Pest / Problem | One-Time Treatment | Notes |
|---|---|---|
| General pests (ants, spiders, silverfish) | $150 – $300 | Interior + exterior application. Most common service call. |
| Cockroaches | $175 – $450 | German roach infestations may require 2 to 3 visits. Gel bait + IGR standard protocol. |
| Mice | $200 – $500 | Includes entry-point assessment. Follow-up visit often needed to clear population. |
| Rats | $300 – $700 | Exterior burrow treatment and bait station setup. Multi-visit programs typical. |
| Bed bugs (chemical) | $400 – $900 | Per-room pricing common. Full-home chemical treatment runs $600 to $900+. |
| Bed bugs (heat treatment) | $1,200 – $2,500 | Whole-home heat for a 2,000 sq ft home. Single-day treatment, highest efficacy. |
| Termites (liquid barrier) | $800 – $2,500 | Perimeter soil treatment. Cost scales with linear footage of foundation. |
| Termites (Sentricon bait system) | $1,200 – $3,000+ | Includes installation + first year monitoring. Annual renewal runs $300 to $500. |
| Wasps / Yellow jackets | $150 – $350 | Nest treatment and removal. Accessible nests at the lower end; attic or wall voids higher. |
| Ticks (single yard treatment) | $150 – $350 | Per-application cost for barrier spray. Seasonal programs (3 to 5 applications) are more effective. |
A few things these numbers do not capture: severity of infestation, square footage of the property, accessibility of treatment areas, and the specific products used. An accessible wasp nest on a first-floor eave costs much less than one inside a wall void under soffit 20 feet up.
What Drives the Final Price
The price difference between a $175 cockroach treatment and a $450 one is not random. These are the factors that actually move the number:
-
Pest species and infestation level German cockroaches require more targeted treatment than American roaches. A light ant problem near the kitchen costs less than an established carpenter ant satellite colony inside wall voids.
-
Square footage and structure complexity More floor area means more product and more technician time. Homes with finished basements, crawl spaces, and multiple access points take longer to treat correctly.
-
Home age and construction type Older Westchester homes with stone foundations, balloon framing, and multiple additions have more entry points and hidden voids. This makes exclusion work more complex and time-consuming.
-
Number of visits required One-time pricing assumes a single visit. Cockroach and rodent programs often require two to three visits at two to three week intervals, and each visit adds to the total cost.
-
Treatment method and products used Heat treatment for bed bugs costs more than chemical treatment because it requires specialized equipment and more technician hours. Premium termiticides with longer warranties cost more than commodity products.
-
Season and scheduling Late spring through summer is peak pest season. Some companies charge more for rush scheduling or same-day service. January is often the quietest time for pest companies, which can mean more negotiating flexibility.
-
Location within Westchester Properties in Scarsdale, Bronxville, and Larchmont command slightly higher prices than those farther from prime residential areas, reflecting travel time, demand, and the general cost structure of those communities.
Service Plans vs. One-Time Treatments
This is where most homeowners make the decision that affects their total annual spend. One-time treatments fix the current problem. Service plans prevent the next one from happening.
The math usually favors a plan. Three one-time calls at $200 each totals $600 and covers only the problems you noticed. A quarterly plan at $500 per year covers those same three visits plus a fourth, includes re-service calls, and catches issues before they escalate. The re-service call benefit is significant: if you see a problem between scheduled visits, the company comes back at no additional charge.
Seasonal Pricing Variations
Pest pressure in Westchester County is not uniform across the year. That affects both what you are likely to see and what services are most in demand:
| Season | Peak Pest Activity | Pricing Notes |
|---|---|---|
| Spring (Mar–May) | Termite swarmers, ants, stinging insects, rodent activity | Termite inspections and treatments peak. Wasp nests begin forming. Busiest period for pest companies. |
| Summer (Jun–Aug) | Mosquitoes, ticks, wasps, ants, occasional roaches | Tick and mosquito programs in high demand. Some companies book 2 to 3 weeks out for routine service. |
| Fall (Sep–Nov) | Rodents, stink bugs, spiders, boxelder bugs entering homes | Rodent exclusion bookings surge September through November. Exclusion work costs more due to demand. |
| Winter (Dec–Feb) | Rodent harboring, German cockroaches, overwintering cluster flies | Lowest demand season. Best time to negotiate plan pricing or schedule non-emergency services. |
Termite Treatment Cost: A Separate Category
Termite remediation deserves its own discussion because the cost range is so wide and the stakes are so high. Eastern subterranean termites are the primary species in Westchester County, and they can cause tens of thousands of dollars in structural damage before a homeowner notices anything.
The two main treatment approaches differ significantly in how they work and what they cost:
| Treatment Method | How It Works | Cost Range | Ongoing Cost |
|---|---|---|---|
| Liquid barrier (termiticide) | Professional-grade termiticide applied to soil around foundation perimeter, creating a treated zone termites cannot cross. | $800–$2,500 | Re-treatment every 5 to 10 years. No annual monitoring fee. |
| Sentricon bait system | Bait stations installed around perimeter. Workers carry bait back to colony, eliminating it over time. Stations monitored regularly. | $1,200–$3,000 | $300 to $500/year for monitoring and bait replenishment. |
For most Westchester homes, liquid barrier is the more cost-effective one-time solution. Sentricon makes sense for properties where soil disruption near the foundation is difficult (flagstone patios, finished basements with slab, landscape beds against the foundation). The monitoring component of Sentricon also gives peace of mind that active protection is in place, which some homeowners and real estate transactions specifically require.
Getting a Free Estimate: What to Ask
Most reputable companies offer free estimates for general pest control and termite inspections. Here is how to use that process to your advantage:
Ask specifically what the estimate includes. An estimate for "ant control" might cover one interior kitchen treatment or it might cover interior and exterior with follow-up. Know which one you are getting before you compare quotes.
Ask about re-service policy. A $250 one-time treatment that includes a free re-service visit within 30 days is worth more than a $200 one-time treatment with no follow-up included. Factor this in.
Ask what products they use and why. A company that can explain product selection by pest species and infestation level is more credible than one that gives a generic answer. NY DEC-licensed applicators should be comfortable discussing this.
Ask whether the technician is the same person each visit. Consistency matters, especially for rodent programs and cockroach treatments. A technician who has seen your home before can spot what a first-time visitor misses.
Get the warranty in writing. For termite treatments especially, verify the warranty period, what triggers a free re-treatment, and whether the warranty transfers if you sell the home.
Budget Pest Control vs. Premium Service: What the Difference Buys You
The cheapest quote is rarely the best value in pest control. This is not a pitch for higher prices. It is a description of what the price difference actually reflects.
Budget services typically rely on general broadcast spraying with commodity pesticides. These products have shorter residual periods, require more frequent reapplication, and do not address harborage or entry points. You get treated, the visible pest population drops, and then the problem returns in four to six weeks because the root cause was not resolved.
Premium services use Integrated Pest Management (IPM) protocols. That means a thorough inspection before treatment, identification of entry points and harborage areas, targeted product application (often using less product, not more), and follow-up verification. The per-visit price is higher. The number of visits needed to actually resolve the problem is lower.
The homeowner who pays $175 for the budget treatment and then calls back six weeks later and pays $175 again has spent $350 and still has a cockroach problem. The homeowner who pays $350 for an IPM-based treatment has spent less and has the problem behind them.
Pricing Transparency: Red Flags and Green Flags
You can tell a lot about a company by how they handle pricing conversations.
Green flags: Written estimates before any work begins. Clear breakdown of what is included (initial visit, follow-up, re-service policy). Willingness to explain product selection. NY DEC license number provided on request. References available for termite work.
Red flags: Verbal quotes only, no written confirmation. "Special deals" that require you to commit on the spot. Unusually low bids that do not include follow-up. Vague descriptions of treatment methods. No mention of NY DEC licensing. Pressure to add services not discussed in the initial estimate.

Westchester County Pricing Context
National pest control cost averages circulated online typically reflect data from across the country, including lower cost-of-living markets. Westchester County prices run 20 to 40 percent higher than national averages for most services.
Three factors drive this. First, NY DEC pesticide applicator licensing requirements add to company overhead. Applicators must maintain certifications and continuing education, which is cost that gets passed to customers. Second, labor costs in the greater New York metro area are substantially higher than in suburban markets in the South or Midwest. Third, the housing stock in Westchester tends toward older homes with more complex pest control needs, which takes more technician time per visit.
This is not a reason to overpay. It is context for why quotes that match the national average might represent either unusually lean service or a company that is cutting corners on materials, licensing compliance, or technician training.
Bottom Line
For most Westchester homeowners, here is a practical frame for what to expect:
A single general pest treatment runs $150 to $300. A cockroach or rodent program involving two to three visits runs $300 to $600. A quarterly service plan that covers the whole year runs $400 to $650 and is almost always worth it versus individual calls. Termite treatment is a separate budget item: $800 to $3,000 depending on method and home size. Bed bug heat treatment for a whole home runs $1,200 to $2,500.
The most expensive mistake in pest control is not calling soon enough. Waiting while a cockroach population doubles or a termite colony expands does not save money. It compounds the treatment cost significantly.
