Sherman Conn Tick Season Has Already Begun
April 7th 2025
The Connecticut Agricultural Experiment Station (CAES) has reported early tick activity in the region. Goudarz Molaei, a research scientist and director of CAES's Passive Tick and Tick-Borne Disease Surveillance Program, noted that despite a relatively cold winter, ticks have survived and are now active. This resilience is attributed to their ability to hibernate under leaf litter during colder months. [source]
Emergence of Invasive Tick Species
In addition to native tick species, western Connecticut has seen the emergence of invasive ticks, notably the Asian longhorned tick (Haemaphysalis longicornis). First identified in the state in 2018, this species has been detected in Fairfield and New Haven counties. It can carry up to 30 different pathogens and may transmit diseases already present in local tick populations.
The Connecticut Veterinary Medical Diagnostic Laboratory (CVMDL) at the University of Connecticut confirmed the most recent case of this species in Fairfield. Though not infected with Lyme disease or other common pathogens, its detection signals a need for continued vigilance. [Sources: CT Post, UConn Today]
Emerging Tick-Borne Diseases
The Gulf Coast tick (Amblyomma maculatum), first observed in Connecticut in 2021, has been linked to Rickettsia parkeri rickettsiosis, a disease similar to Rocky Mountain Spotted Fever. This highlights the growing complexity of tick-borne illness in the state.
Preventative Measures for Residents
- Conduct Regular Tick Checks: After spending time outdoors, inspect your body and clothing for ticks.
- Use Appropriate Repellents: Apply products with at least 20% DEET, picaridin, or IR3535. Treat clothing with permethrin.
- Maintain Landscaping: Keep lawns trimmed and remove leaf litter to reduce tick-friendly environments.
- Seek Professional Testing: Send found ticks to local health departments or the CAES for analysis.
By staying informed and taking preventive steps, residents of western Connecticut can protect themselves and their families throughout the 2025 tick season.
