Pest Control in Berlin, NH

Berlin has a cold climate. July highs average only about 76 degrees, January lows about 4, and just around 2 days a year reach 90 degrees. The area receives about 48 inches of precipitation and roughly 96 inches of snow in a typical year, and October is the wettest month at about 5.3 inches. These figures are 1991-2020 NOAA climate normals from a nearby weather station, so treat them as a guide, not a forecast.

Heavy snow that lasts for months gives rodents a covered route to foundations, and the weight of it can loosen flashing, vent covers and siding, creating fresh openings. A wet October just before the snow arrives is the last real chance to seal a building, so we suggest doing exterior work before then instead of waiting for spring.

Spring melt drenches soil and wood, and carpenter ants respond quickly to that moisture. Later, the mild summer still supports mosquitoes wherever water collects. A good annual routine in Berlin is to clear snow and ice from around vents in winter, inspect for water damage in spring, control standing water in summer and seal every gap you can find in September.
