Colonial Pest Control Inc.

Colonial Pest Control is a founder-owned company based in Hooksett, New Hampshire, that's been treating homes for ants, rodents, ticks, termites, and wood-destroying insects across Massachusetts and New Hampshire since 1984. It's one of the more heavily reviewed pest control companies around — 265 reviews since 2023, the overwhelming majority five stars, spread across dozens of named technicians. The reviews describe two kinds of visits, and both come up constantly. The first is the urgent call: a wasp or yellow jacket nest — one review describes a volleyball-sized nest removed from under a pool deck after the homeowner was stung, with the technician also spraying the surrounding area and never charging extra for the return trip. Several other reviews describe similar same-visit wasp removals, with the company consistently praised for responding quickly. The second is the routine, twice-a-year maintenance visit, where technicians are repeatedly described finding and sealing rodent entry points around foundations, bulkheads, and garages before mice become a real problem — several reviewers specifically say a technician found and fixed an entry point they hadn't noticed themselves. What comes up again and again, technician after technician, is that people feel informed rather than just serviced: reviewers describe being walked around the property and shown exactly what's being treated and why, having their questions answered in detail, and being remembered on repeat visits — one customer noted a technician remembered their past problem areas and gave them extra attention without being asked. Several households describe relationships going back decades, including one saying they've been customers since 1986 and another for "the better part of 25 years," having signed up for an annual plan after finding carpenter ants when they first moved in. Not every visit gets a perfect account. One 2026 review, based on the customer's own camera footage, said a technician skipped walking the full perimeter of the house and was on-site only about six minutes. A separate review had no complaint about the actual work but wanted more than five minutes' notice before the technician arrived. Both are worth knowing, though they sit against a very large and otherwise consistent stack of detailed, positive accounts covering the same kind of visit. The company says it's still founder-owned and locally operated after more than 40 years, with state-licensed technicians serving both states. For ongoing pest prevention, a wasp or rodent emergency, or termite and wood-destroying-insect treatment across Massachusetts or New Hampshire, this is a company with an unusually deep and consistent written history behind it.
