How Much Does Pest Control Cost in Cambridge, MA? (2026)

A one-time pest control visit in Cambridge, MA costs $175 to $350 for common problems like ants, mice, or wasps. Quarterly service plans, which most Cambridge homeowners and landlords end up on, run $45 to $85 a month. Bed bug treatment is the expensive outlier at $1,000 to $3,500 per unit, and rats in a multi-family building can run $500 to $1,500 for the initial program.

Cambridge prices run about 20 percent above the Massachusetts average. The city is dense, the buildings are old, parking for a service van is a real cost, and the September 1 lease turnover pushes a huge share of the year's pest calls into one month. Below is what each type of job costs in the city right now, what changes the number, and how to avoid paying twice.

Mice and Rats in Cambridge Buildings

Mice are the most common pest complaint in Cambridge, and the triple-deckers and rowhouses in Cambridgeport, Mid-Cambridge, and East Cambridge are built for them. Balloon framing, shared walls, and 120-year-old sill plates leave plenty of entry points.

An initial mouse treatment runs $200 to $400 for a single unit. That includes an inspection, bait stations or snap traps, and sealing the obvious gaps. Follow-up visits run $75 to $150 each, and most companies recommend two.

Full exclusion, where a technician seals every gap larger than a quarter inch with steel wool, hardware cloth, and mortar, is where the real money goes. Exclusion on a Cambridge single-family runs $600 to $2,000 depending on the foundation and porch conditions. It is also the only thing that ends the problem instead of managing it.

Rats are a bigger issue than they were five years ago, especially near construction sites in Kendall Square and along the Charles. Rat programs start at $400 to $700 for a single building and run $100 to $200 per month for ongoing bait station service. Landlords with a rat problem should expect the city's Inspectional Services Department to get involved if tenants complain, so it pays to act first.

Bed Bugs and the September 1 Problem

Cambridge has one of the highest bed bug call volumes in the state per capita, and it spikes every fall. Thousands of leases turn over on September 1, used furniture goes out on the curb and back inside, and by mid-September pest companies are booked two weeks out.

Chemical treatment for bed bugs runs $400 to $900 per room and usually requires two or three visits. A one-bedroom apartment typically totals $1,000 to $1,800. Heat treatment, where the unit is brought above 120 degrees for several hours, runs $1,500 to $3,500 for a one-bedroom and is done in a single day.

Heat is the better option in Cambridge multi-families because it kills eggs and does not depend on tenants doing every step of the prep work. Chemical treatment is cheaper up front but fails more often in buildings where bugs travel between units.

Canine inspections, where a trained dog sniffs out live bugs, run $200 to $400 and are worth it for landlords trying to figure out which units in a six-unit building are affected before paying for treatment everywhere. Under Massachusetts sanitary code, the landlord is responsible for treatment cost in most cases.

Ants, Cockroaches, and Wasps

Carpenter ants show up every spring in Cambridge's wood-frame houses, especially in homes with older porches and window frames that stay damp. A carpenter ant treatment runs $250 to $500 and includes locating the nest, which is often in a porch column or a wall cavity near a leaking gutter.

Pavement ants and odorous house ants are cheaper at $150 to $300 per treatment. Many companies fold ant control into a quarterly plan rather than charging per visit.

German cockroaches are mostly a restaurant and apartment problem. Treatment runs $200 to $500 per unit for gel bait and growth regulators, with follow-up at $100 to $150. A cockroach problem in a Central Square apartment building can take three months to clear, and it rarely stays fixed if only one unit is treated.

Wasp and hornet nest removal runs $150 to $350 depending on height and location. Nests inside soffits or wall voids cost more because the technician has to open and reseal the area. Yellow jackets in the ground near a Huron Village patio are a quick job at the low end.

Quarterly and Annual Plans

Most Cambridge pest companies push a quarterly service plan, and for a lot of properties it makes sense. Plans run $45 to $85 a month for a single-family or condo, billed quarterly at $135 to $255 per visit. Multi-family plans run $100 to $250 per month for a three or six-unit building.

The plan covers routine exterior treatment, interior visits on request, and free re-treatment between scheduled visits. It does not usually cover bed bugs, termites, or wildlife, which are quoted separately.

Whether a plan is worth it depends on the building. A renovated condo in a newer building near Alewife probably needs one or two visits a year at most, and paying per call is cheaper. A 1900s triple-decker with tenants, a dirt-floor basement corner, and a shared back porch will use the plan and then some.

Read the contract length. Some companies require a 12-month commitment with an early termination fee of $100 to $200, and others are month to month. The month-to-month option is worth a few extra dollars for flexibility.

What Makes a Cambridge Job Cost More

Parking is the first thing. Technicians in Cambridge spend real time finding a spot, and some companies add a $15 to $30 city surcharge or simply price the whole job higher. Having a driveway or a guest permit ready shortens the visit.

Building age is the second. A 1890s home in Avon Hill with stone foundation and multiple additions has far more entry points than a 1990s condo, and exclusion work scales with the number of gaps. Expect to pay 30 to 50 percent more for exclusion on an older building.

Multi-unit coordination is the third. Treating one unit for cockroaches or bed bugs while the neighbors do nothing is a waste of money. Companies charge less per unit when they treat a whole building at once, but the total bill lands on the owner.

Timing is the last. Calling in the second week of September for anything means paying peak rates and waiting. Calling in February means a quick appointment and often a discount.

Choosing a Pest Control Company in Cambridge

Massachusetts requires pesticide applicators to be licensed through the Department of Agricultural Resources, and companies need a separate business license. Ask for both numbers, and expect a legitimate operator to give them without hesitation.

The pest control companies working in Cambridge and Somerville should each be able to show current licensing. If one cannot, move on to the next.

Ask specifically about exclusion. Many companies are happy to sell you a bait station plan forever, and the good ones will tell you where the mice are getting in and quote a fix. If the technician never goes into the basement or looks at the porch, they are not solving the problem.

Get the treatment plan in writing, including which products will be used, how many visits are included, and what the re-treatment guarantee covers. For bed bugs, ask for a written guarantee period of at least 30 to 60 days after the final visit.

Check reviews for mentions of September response times and for how the company handles callbacks. Cambridge has a couple of dozen active operators, and the difference between them is mostly follow-through.

A single visit for ants, mice, or wasps runs $175 to $350 in Cambridge, which includes the inspection and initial treatment. Follow-up visits, if needed, are usually $75 to $150 each.

Who pays for pest control in a Cambridge rental?

Under the Massachusetts State Sanitary Code, the landlord is responsible for keeping a rental free of pests, including bed bugs, unless the tenant caused the infestation. Tenants should report problems in writing, and landlords generally have a short window to respond.

How much does bed bug treatment cost for a one-bedroom in Cambridge?

Chemical treatment totals $1,000 to $1,800 across two or three visits. Heat treatment runs $1,500 to $3,500 in a single day and has a better success rate in multi-family buildings where bugs move between units.

Is a quarterly plan worth it for a Cambridge condo?

For a newer condo with few entry points, usually not. Paying $200 to $300 for the one or two visits you need each year is cheaper than $540 to $1,020 for a plan. Older triple-deckers with tenants are a different story and often use every visit.

How fast can I get a pest control appointment in Cambridge?

Most of the year, one to three days. In September, expect one to two weeks for non-emergency calls as move-in season floods every company with bed bug and mouse work.
