Tick activity in Fairfield County is already running ahead of schedule in 2026, with early-season data signaling a heightened risk for homeowners. According to the Connecticut Agricultural Experiment Station, April tick submissions are tracking at levels typically seen in peak months like May and June. Population estimates suggest tick numbers are roughly 25% higher than last year, while infection rates remain among the highest in the state. Data shows approximately 68% of adult ticks in Fairfield County carry Lyme disease, according to state surveillance, and early 2026 testing indicates more than 40% of ticks submitted this season are already positive. With nymph-stage ticks—responsible for most human infections—emerging in the coming weeks, public health officials are warning that the conditions are in place for a particularly active season, underscoring the need for preventive measures at home.
