Colonial Pest Control Inc.

Colonial Pest Control has been treating homes around Worcester and beyond for decades — one reviewer says a technician "represents the best of the Colonial Pest service we have known for nearly 30 years," and the company's Google record runs 624 reviews deep since 2021, with 428 more landing in just the last six months. Averaging 4.9 stars across more than 1,600 ratings, that kind of volume says something about consistency. The through-line in the reviews is communication: technicians call ahead, explain what they're spraying and why, and walk customers through what they found. Ricky and Joseph "let me know before they began work" and gave pet warnings; Paul was praised for explaining everything before scheduling follow-up service; a crew even told one customer a suspected mouse problem was actually old bat droppings and skipped the charge for the visit. Several customers describe multi-year, even decade-long, contracts for twice-a-year perimeter treatment against ants and termites. Not every visit lands the same way. In a 2025 review, a homeowner described moving into a beach house Colonial had treated the year before to find mice, urine and droppings throughout the ceiling, and said a follow-up technician arrived with no record of the earlier treatment on file despite a $274 bill already paid — a frustrating gap in record-keeping on an otherwise busy account. It reads as an outlier next to the rest of the record, but it's worth asking about if you're booking a rental or a property that sits vacant between visits. Colonial carries an A+ rating and accredited status with the Better Business Bureau, whose listing also cites a Massachusetts pesticide applicator license number for the company — that's BBB's record rather than something verified against the state registry here, so it's worth confirming the license is current before signing a contract. This is a company built around routine, contracted pest management — biannual sprays, ant and rodent exclusion, perimeter termite treatment — rather than one-off emergency jobs, though when a hornet nest needed same-day removal for safety, Colonial found room in a busy season after four other companies couldn't. For an ongoing pest contract in the Worcester area, the record here is deep and mostly reassuring; just get specifics on record-keeping if a property changes hands or sits empty between visits.
