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.

We're so grateful our friends recommended Lighthouse Exterminators for our seasonal spray treatments. Dan is incredibly thorough and has made a noticeable difference in reducing the number of mosquitoes on our property. He's also been treating our yard for ticks, which has given us even more peace of mind when spending time outside with the kids and our dog. Dan is a pleasure to work with- professional, reliable, and reasonably priced. We truly appreciate his excellent service and highly recommend Lighthouse Exterminators to anyone looking for effective, dependable pest control.

After calling 8 other pest control services I found Lighthouse. They were the only ones who could get the job done (removing a hornets nest) on the same day. They were very efficient and responsive and also had the most reasonable price. Highly recommend.

I feel lucky that we were fortunate to find Dan. He was easy to work with and had a solution that was effective. I was a bit of a wreck before we had our situation resolved. I highly recommend him and would use him again if any other problems occur.
