Pest control service in Waltham

Waltham has 37% of housing units built before 1939, with dense multi-family housing in the southern section and larger lot single-family housing in the northern section. The city's proximity to the Charles River makes it particularly susceptible to pests that thrive in damp environments, such as mosquitoes and termites. 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.

Pest Control Built for Waltham's Older Housing Stock

With 37% of units built before 1939 and another 22% from 1940–1959, Waltham's older housing stock requires specialized termite and rodent treatment. Lighthouse Exterminators understands how pre-war wood framing, foundation gaps, and deteriorated seals in south Waltham's dense multi-family buildings create entry points for pests.

The Charles River's proximity makes Waltham susceptible to moisture-loving pests like termites and mosquitoes. Our bed bug heat treatment, crawl space remediation, and attic sealing address the damp conditions that attract and harbor infestations in riverside and low-lying properties.

Cold winters drive rodents and overwintering insects indoors. We combine rodent control, exclusion work, and foundation sealing to seal vulnerable entry points before pest populations surge in fall and winter.

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.
