How Much Does Pest Control Cost in Boston, MA? (2026) What Mice, Carpenter Ants, and Bed Bugs Cost to Fix

Boston homeowners pay roughly $200 to $350 for a one-time general pest treatment and $400 to $700 a year for a recurring plan billed quarterly. The initial visit on most contracts costs $150 to $300 by itself, then maintenance visits settle in at $90 to $150 apiece. Anything involving mice, bed bugs, or carpenter ants sits in a different price band entirely.

The cost driver in this city is the building, not the bug. Boston's residential fabric runs heavy on triple-deckers, rowhouses, and pre-1940 wood frame construction with fieldstone or rubble foundations, and those basements are full of gaps that a mouse can use. A technician quoting a house in Dorchester or Somerville is pricing the labor of sealing a foundation as much as the product going on the baseboards.

Season matters too, and it moves demand more than it moves the rate card. Mice and rats push indoors starting in late September, carpenter ants swarm in April and May, and bed bug calls run flat all year. Companies book out two to three weeks during the fall rodent rush, and a job you schedule in February often gets on the calendar within days.

How Recurring Plans Are Priced Here

Quarterly service is the standard offering, and a single-family home in West Roxbury or Roslindale usually prices at $110 to $160 per visit after the initial treatment. Condo units and small apartments run $75 to $120 because there is less exterior perimeter to treat. Annual contracts almost always beat paying per incident once you have had two problems in a year.

What the plan covers is narrower than the marketing suggests. A general plan handles ants, spiders, roaches, silverfish, centipedes, wasps, and often mice at a basic bait-and-monitor level. Bed bugs, carpenter ant structural work, termites, wildlife, and tick yard treatment are separate line items with separate agreements.

The Boston twist is exterior access. In a triple-decker with a shared driveway and a neighbor's fence three feet off your foundation, a technician cannot always run a full perimeter treatment. Some companies price those buildings higher because the work shifts to interior crack-and-crevice application, which takes longer and requires you to be home.

Multi-unit buildings get quoted per unit plus common areas. A three-family typically runs $180 to $300 per quarterly visit for the whole building, which is cheaper per door than three separate contracts. Owner-occupants of two-family and three-family homes should ask for the building rate rather than the single-unit rate.

Mice, Rats, and the Cost of Sealing an Old Foundation

A basic mouse treatment with interior and exterior bait stations costs $250 to $500 for the first service, with follow-ups at $80 to $150. That price buys population knockdown and nothing more. If the entry points stay open, the mice come back with the first cold snap in October.

Exclusion is the work that fixes it, and it prices separately at $500 to $2,500 depending on how much of the foundation, sill plate, and utility penetration needs sealing. Copper mesh and sealant around pipe chases, hardware cloth over crawl space vents, door sweeps on bulkheads, and mortar repair on a rubble foundation all take hours. A century-old Jamaica Plain two-family can easily hit the top of that range.

Norway rats are a different job and a bigger number. Exterior burrow baiting programs run $400 to $1,200 for an initial setup with monthly monitoring at $75 to $175, and rat work in the denser neighborhoods usually needs to continue as long as the food source next door does. Boston's rodent activity tracks construction, trash storage, and alley conditions more than it tracks any one property's cleanliness.

Ask any company quoting rodent work whether the price includes a written exclusion report with photos. The ones doing real work document every gap they seal, and the ones just dropping bait boxes have nothing to show you.

Carpenter Ants and Moisture in Pre-1940 Houses

Carpenter ants are the most common structural pest complaint in Greater Boston, and a treatment runs $300 to $700 for a typical single-family home. The colony lives in wet wood, which is why the ants show up where a gutter has been overflowing for three winters or where an old porch roof meets the siding. Killing the visible workers without finding the moisture accomplishes very little.

The inspection is what you are paying for on the good jobs. A technician who spends 45 minutes checking sill plates, window headers, bathroom subfloor, and the area under a leaking skylight is going to find the nest. One who sprays the kitchen and leaves will be back in six weeks, on your dime if the warranty is thin.

Satellite colonies complicate the pricing. A mature carpenter ant colony in a Cambridge or Brookline house often has a parent nest in a tree or stump outside and satellites inside the wall cavities, so treatment includes exterior perimeter work and targeted injection into the voids. Expect two or three visits over four to six weeks on a job done properly.

Wood repair is never included. Once ants have galleried out a section of sill or a porch column, a carpenter takes over, and that work runs from a few hundred dollars for a trim replacement into the thousands for structural framing. Pest companies will point at the damage and stop there, which is the correct division of labor.

Massachusetts does have subterranean termites, mostly in the coastal and southern parts of the state, and Boston sees them in older neighborhoods with wood in contact with soil. A liquid barrier or bait installation runs $1,200 to $3,000, and an annual bond costs $250 to $500. Termites are far less common here than carpenter ants, and a company that diagnoses termites on sight without showing you mud tubes or damaged wood deserves a second opinion.

Bed Bug Treatment in Dense Housing

Bed bug work is the highest priced routine service in Boston, and the range is wide. Chemical treatment of a one-bedroom apartment runs $500 to $1,200 across the two or three visits a proper protocol requires. A full single-family home climbs to $1,500 to $3,000.

Whole-unit heat treatment costs $1,200 to $3,500 for an apartment and $2,500 to $6,000 for a house. Heat kills every life stage in one session, including eggs, which is why it appeals to landlords trying to turn a unit fast. It also requires the crew to raise the entire space above 120 degrees for several hours and to protect anything heat sensitive.

Density is what makes this expensive in Boston. Bed bugs travel between units through wall voids, outlets, and shared baseboards, so treating one apartment in a six-unit building without inspecting the neighbors often fails. Good companies insist on inspecting adjacent units, and that inspection adds $100 to $300 per unit.

Preparation is the hidden cost. Bagging laundry, running everything through a hot dryer, and moving furniture takes days of your time, and some companies now sell prep services at $200 to $600 because tenants and owners rarely complete it correctly. A failed treatment caused by incomplete prep usually voids the warranty.

Ticks, Mosquitoes, and Yard Treatment Outside the Core

Tick and mosquito barrier spraying costs $75 to $150 per application on a typical suburban lot, with seasonal programs of six to eight treatments running $450 to $1,000. Demand runs highest in the wooded neighborhoods and the towns just outside the city where lawns meet brush and stone walls. Deer ticks carrying Lyme disease are established across eastern Massachusetts, and the exposure risk peaks from May through July.

Yard modification does more than spraying alone. Cutting back the brush line, moving woodpiles off the lawn edge, and installing a three foot gravel or wood chip border between lawn and woods cuts tick migration into the play area. Landscapers handle that work, and it costs once instead of every three weeks.

Tick tube programs are the other option, placed twice a season at $200 to $500 a year. They target the mice that carry the ticks rather than the ticks themselves, and results build over two or three seasons rather than showing up immediately.

Licensing, Landlord Duties, and Checking a Company Out

Massachusetts licenses pesticide applicators through the Massachusetts Department of Agricultural Resources, and anyone applying pesticides commercially must hold a valid applicator license or be a registered technician working under a licensed applicator. Companies must also hold a pesticide dealer or commercial certification appropriate to the category of work. Ask for the license number and verify it before service, not after.

Rental housing carries its own rule set. Under the state sanitary code, owners of buildings with two or more units must maintain the property free of insects and rodents, and extermination in those buildings is the owner's responsibility rather than the tenant's. Boston Inspectional Services enforces that locally, and a documented complaint tends to move a stalled landlord faster than another phone call.

Insurance and written scope are the last two checks. Get a certificate of general liability, and get the agreement in writing with the target pests, visit count, warranty period, retreatment terms, and the renewal price after the first year listed separately. Introductory pricing that jumps 40 percent at renewal is the most common billing complaint in this market.

Comparing two or three licensed pest control companies near you on the identical scope is the fastest way to see which quote is padded. Our guides to Massachusetts home service costs cover the seasonal timing that decides how long you wait for an appointment.

Frequently Asked Questions

How much does it cost to get rid of mice in a Boston triple-decker?

Baiting and trapping runs $250 to $500 for the initial service, and sealing the entry points on a rubble or fieldstone foundation adds $500 to $2,500. Buildings with shared basements usually need all three units treated together, since mice move freely between floors through utility chases.

Is quarterly pest control worth it in Boston?

For an older single-family or a two-family with a basement, yes, since the $400 to $700 annual cost is less than two emergency treatments. Newer condo units with sealed slabs and no direct exterior access often do fine calling only when something appears.

How much does bed bug heat treatment cost in Boston, MA?

Heat treatment runs $1,200 to $3,500 for an apartment and $2,500 to $6,000 for a full house, compared with $500 to $1,200 for a multi-visit chemical protocol in a one-bedroom. Heat finishes in a single day, which is why landlords use it between tenancies.

Who pays for extermination in a Boston rental?

In buildings with two or more units, the state sanitary code puts extermination of insects and rodents on the property owner. Single-family rentals are handled differently, and the lease language controls, so read it before assuming the bill is yours.
