Pest Control in New Hampshire

Weather differs from one part of New Hampshire to another. Across the communities we serve, July highs average roughly 82°F, ranging from about 76 to 85°F, while January lows average near 13°F. A typical year brings roughly 46 inches of precipitation, from about 38 inches in the driest of our cities to about 52 in the wettest, and about 158 nights a year at or below freezing. These figures are climate averages from local weather records for 98 cities, so they describe the pattern, not a forecast.

Winters in the hills and valleys run long, and that shapes every pest calendar. Most insects go quiet under snow and leaf litter, but rodents keep looking for warmth, so the real window for exclusion work is early autumn. Sealing foundation cracks, vent screens and door gaps before the first hard cold prevents most winter calls.

Once thaw arrives, activity comes back quickly. Ants wake up first, often inside walls that stayed warm, and the wet spring soaks soil and wood in ways that draw in moisture-loving species. Later in the season, humid stretches favor mosquitoes and ticks. Because the active season is compressed, a spring inspection of gutters, decks and crawl spaces pays off, and extermination visits timed to those bursts work better than random appointments.
