Pest Control in Exeter, NH

The pests we treat most often in Exeter track the town's rivers and its historic housing. Blacklegged (deer) ticks are a real concern along the river corridors and conservation land, and UNH Extension notes that most of New Hampshire's blacklegged ticks live within 35 miles of the coast. The tidal Squamscott and Great Bay marshes, along with freshwater swamps, breed both nuisance and arbovirus mosquitoes, and NH DHHS names Rockingham County the state's highest-risk area for EEE. Carpenter ants nest in the older sills of Exeter's many pre-1940 wood-frame homes, mice push into the dense downtown each fall, and cluster flies and stink bugs gather on warm walls. We tailor treatment to whichever of these your property actually faces.

Yes. Roughly 21 percent of Exeter's homes predate 1940, and that older wood-frame stock changes what we look for. Aging sills, framing, and moisture points in a historic house are exactly what carpenter ants seek out to establish a nest, and the small gaps and shared wall voids in older downtown and multifamily buildings give mice the entry points and harborage they need heading into winter. We inspect the sills, cellar, and utility penetrations closely on an older home, seal the gaps that let rodents in, and target carpenter-ant activity at the damp wood where it starts, rather than applying a one-size treatment that ignores the way these buildings are put together.

In the Exeter area tick activity runs any time temperatures top 40 degrees, with blacklegged tick nymphs — the stage most likely to spread Lyme — most active May through August (UNH Extension), so tick protection matters across most of the outdoor season. Mosquito-borne risk builds through the summer during the NH DHHS active season of June through October and peaks in late August and September near the Squamscott tidal marshes and Great Bay; in 2024 the state logged two human EEE cases, one death, and seven positive mosquito batches, with Rockingham County flagged as highest-risk. We time treatments to these windows and concentrate on the wooded edges, marsh margins, and shaded parts of your property where both pests are worst.

Our Rochester office is about 42 minutes and roughly 29 miles from Exeter, close enough for same-week service across the historic downtown and the Squamscott riverfront. Because we already work throughout Rockingham County and the Seacoast, our licensed New Hampshire technicians know the local pest pressure — the tick-heavy river corridors, the EEE-risk tidal marshes, and the carpenter ants and rodents that come with older downtown housing. 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.
