Pest Control in Hillsborough, NH

The pests we treat most often in Hillsborough track the town's rivers, forest, and older housing. Deer ticks lead the list: Fox State Forest and Hillsborough's wooded edges create prime blacklegged-tick habitat, and UNH Extension ranks Hillsborough County among New Hampshire's highest for Lyme disease, with roughly 60% of the state's adult ticks infected. Mosquitoes breed in Fox Forest's Black Gum Swamp and Mud Pond bog and along the Contoocook River, and NH DHHS submitted local mosquitoes for arboviral surveillance during the 2024 EEE season. Carpenter ants nest in the moisture-damaged wood common in homes built before 1940 in Center and Lower Village, and mice move into both historic housing and vacant lake camps each fall. We tailor treatment to whichever your property actually faces.

It often does. About a fifth of Hillsborough's homes were built before 1940, and that older housing stock in the Center and Lower Village districts carries a median construction year of 1944. Aging foundations, settling sills, and gaps around utility penetrations give mice easy paths inside and give carpenter ants access to moisture-damaged structural wood, especially where the Contoocook River keeps ground moisture higher near downtown. The same older, sun-warmed walls also draw cluster flies and other overwintering insects each fall. We approach historic homes with exclusion first — sealing entry points and reducing harborage — rather than relying on treatment alone, so the structure itself stops working against you.

In New Hampshire, ticks are active whenever the ground is not frozen, roughly March through November, with nymphal deer ticks peaking from late May through July and adult deer ticks again in October and November — so tick protection matters across most of the year your family spends outdoors near Fox State Forest or along the Contoocook. Mosquito and arboviral surveillance runs June through October, and NH DHHS submitted Hillsborough County mosquitoes for testing during the 2024 season, when the state saw its first fatal EEE case in a decade. We time tick and mosquito treatments to these windows and concentrate on wooded property edges, wetland margins, and shaded yards where both pests are worst.

Our Manchester office is about 51 minutes and roughly 37 miles from Hillsborough via US-202 and NH-9, close enough for scheduled service across downtown Bridge Village, Hillsborough Center, and the outlying villages toward Bible Hill and Emerald Lake. Because we already work throughout the Monadnock region, our licensed New Hampshire technicians know the local pest pressure — the deer ticks near Fox State Forest, the mosquitoes breeding in its wetlands, and the carpenter ants in the town's historic homes. When you call (603) 785-0118 we'll schedule an inspection, explain exactly what we found, and back the visit with our 30-day guarantee so you are not paying twice for the same problem.
