Termites in Wisconsin
Weather-driven termites risk forecasts for Wisconsin cities and counties.
Eastern subterranean termites are the most destructive wood pest in Wisconsin, causing more property damage annually than fires and storms combined. Our termite forecasts track the warm, moist conditions that drive swarming and colony expansion.
Seasonal Pattern
Termite swarming season in Wisconsin peaks March through June, when warm rain events trigger reproductive flights. Subterranean termites remain active underground year-round but expand most aggressively when soil temperatures reach 65°F and moisture is abundant.
Weather Influence
Termite activity is driven by soil moisture and temperature. Heavy rain followed by warm days (65-85°F) creates ideal swarming conditions. High humidity (>70%) supports colony survival. Subterranean termites require direct soil-to-wood contact and persistent moisture to establish colonies.
