  • Per-pest figures are local treatment prices at light severity; a typical one-time general visit lands around $244.
  • The severity factor (1.5× moderate, 2.5× severe) covers what established infestations actually demand — exclusion work on rodents (sealing entry points can push a mouse job toward $700), repeat visits, and larger treatment areas.
  • Bed-bug pricing is per room treated chemically; severe or recurring cases usually justify whole-home heat treatment at $1,100–$5,200 instead, which kills every life stage in one day.
  • Inspections are free from most companies in the area — a charge to look at routine pest activity is a yellow flag. The paid exception is a formal termite/WDI report for a home sale.
  • Termite figures cover treating eastern subterranean termites, the only kind here; ongoing monitoring bonds run $100–$600 per year on top. No drywood termites in New England means tent fumigation should never appear on a local quote.

Ranges are built from published New England contractor pricing and regional cost indices, scaled to Maine (×1.00 on the Greater Boston baseline that the written figures on this page quote), last reviewed 2026-11.

What drives the price

The pest sets the price

There's a 10–30× spread between the cheapest and most expensive jobs in this trade — a $100 wasp nest versus a multi-thousand-dollar termite or bed-bug program. Identification comes first, and since inspections are free from most Washington-area companies, it costs nothing to know what you're pricing.

One visit or a plan

A quarterly plan at $325–$1,200 a year beats repeat one-time calls at $131–$341 each somewhere around the third visit. Plans make sense for recurring seasonal pressure — mice every fall, ants every spring; a one-off problem in an otherwise tight house doesn't need a subscription.

How established it is

An infestation caught at a few sightings is a light job; an established colony across multiple areas can run 2.5× the base price in visits, materials, and exclusion work. Pests compound — calling in week one instead of month six is the single cheapest decision in this trade.

Old housing stock

Washington's triple-deckers, fieldstone foundations, and shared walls give pests entry points newer construction doesn't have — and in multi-family buildings, treating one unit while a neighbor's goes untreated rarely holds. Exclusion work and building-wide coordination are what quotes in the area's older neighborhoods are really pricing.

Pest Control cost questions, answered

How much does an exterminator cost in Washington?
A one-time general treatment runs $131–$341 in the Washington area, with most visits around $244. Ongoing quarterly plans run $325–$1,200 per year plus an initial clean-out visit at $154–$303. The pest changes everything, though: a wasp nest is a $100–$500 call, while a termite job runs $800–$3,400 — get the problem identified (usually free) before comparing prices.
How much does it cost to get rid of mice in Washington?
A baseline trap-and-bait program runs $150–$350. The lasting fix is exclusion — sealing the gaps, utility penetrations, and foundation cracks mice use — which can push the job toward $700. In Washington's older housing stock, exclusion is usually the difference between solved and recurring: treatment without it is a subscription, not a cure.
How much does bed bug treatment cost?
Chemical treatment runs $200–$425 per room, so a two-to-three-room apartment lands around $400–$1,275 over the required visits. Whole-home heat treatment runs $1,100–$5,200 and kills every life stage in a single day, which is why severe or recurring cases usually justify it. Either way, treat every room with activity — skipping rooms is the most common reason treatments fail.
How much does termite treatment cost in Maine?
Termite treatment runs $800–$3,400, with most jobs at $1,500–$2,300 for liquid soil treatment or a bait system, plus an optional monitoring bond at $100–$600 per year. Maine, like the rest of New England, only has eastern subterranean termites. There are no drywood termites here, so tent fumigation is never the right prescription. If a company pitches tenting, get a second opinion.
When are carpenter ants active in Maine?
Carpenter ants swarm May through July in New England — that's when winged ants indoors mean a nest in the structure. Treatment runs $175–$1,300, typically $375–$500. They excavate moisture-damaged wood rather than eating it, so the ants are a symptom: a good treatment plan finds the leak or damp sill that invited them, not just the trail.
