Pest control service in Watertown

Watertown's housing stock is primarily pre-1939, making it one of America's oldest residential areas, with a diversity of single-, two- and multi-family units. Warm, moist summers give way to cold winters, which means over-wintering insects, rodents, and other small wildlife need to find warm places to wait out the cold. Roaches and silverfish may be more of an issue in areas with more rainfall, like Watertown.

Pest Control Built for Watertown's Historic Homes

With 45% of Watertown's homes built before 1939, older wood framing, foundation gaps, and deteriorated seals create multiple pest entry points. Lighthouse combines heat treatment for bed bugs, exclusion work to seal foundation and attic gaps, and termite inspections to protect aging structural timber.

Cold winters drive rodents and over-wintering insects indoors. Our rodent control and attic sealing prevent winter infestations before they start. We also handle post-pest restoration—contaminated insulation removal and attic sanitization—critical in older homes where rodent waste accumulates in original insulation.

Watertown's mix of residential and commercial properties—from multi-unit buildings to office and retail spaces—requires flexible service delivery. We offer WDI Form 33 inspections for property transactions, commercial property pest inspections, and crawl space remediation for the older basement conditions common throughout the city.

From start to finish Dan and his team were so knowledgeable about all my concerns with kids and pets being around . My issue was resolved in just a couple of visits. This company stood out to me because there was no high pressure sales pitch and the results and price so nice .

I cannot recommend Dan and Lighthouse Exterminators highly enough. We were dealing with a terrible rat infestation in our home in JP, and after hiring another company that charged us a fortune and accomplished virtually nothing, we were frustrated and desperate for a solution. Dan was a breath of fresh air. He came out almost immediately and, rather than simply setting traps and hoping for the best, took the time to understand the problem and figure out how the rats were getting into our house. He suggested that we request a free sewer smoke test from the city—something the first company had never even mentioned—which ultimately pinpointed the source of the infestation. Dan then returned, sealed the opening, and exterminated the remaining rats. Throughout the process, Dan was incredibly responsive, knowledgeable, and thoughtful. He genuinely cares about his customers and takes pride in solving their problems. His pricing was also extremely reasonable. I am incredibly grateful for his help and would recommend Lighthouse Exterminators without hesitation to anyone dealing with a pest problem.

Lighthouse Exterminators is a fantastic company! From the very beginning, Lindsey was incredibly helpful and responsive when scheduling my appointment. When Dan came out for the service, he was friendly, professional, thorough, and extremely knowledgeable. He took the time to answer all of my questions and made sure everything was addressed. He was looking to solve the problem, not just put a Band-Aid on things. The entire experience was seamless, and it's clear they truly care about providing excellent customer service. I highly recommend Lighthouse Exterminators to anyone looking for a reliable and trustworthy pest control company.

Dan was extremely responsive from the moment I reached out and was able to get me on the schedule right away to sanitize and remove the insulation from my unfinished basement. He did an extremely thorough job, and I would highly recommend.
