An Early Tick Surge in Connecticut Has Scientists Concerned
Connecticut Seeing Unusually High Tick Activity (2026)
Scientists in Connecticut are reporting an early and unusually intense start to tick season, raising concerns for residents across the state.
What’s happening
- The Connecticut Agricultural Experiment Station is receiving over 100 tick submissions per day—levels typically seen later in peak months like May, June, or fall.
- This surge is occurring much earlier than expected, which researchers describe as concerning.
- A colder winter, which would normally reduce tick populations, does not appear to have significantly impacted their numbers this year.
Disease risk is higher
- About 40% of ticks tested are carrying Lyme disease, compared to a long-term average of around 32%.
- Ticks in Connecticut can also spread other illnesses, including babesiosis and anaplasmosis.
Why this is happening
- Researchers point to a combination of factors, including:
- Climate change
- Shifts in temperature and humidity
- Expanding vegetation and habitats
More tick species are present
- In addition to common deer ticks, Connecticut is seeing more invasive species such as:
- Lone star ticks
- Gulf Coast ticks
- Longhorned ticks
- These species can carry different pathogens, increasing overall health risks.
What people should do
- Use tick repellents when outdoors
- Perform regular tick checks after spending time outside
- Be cautious in grassy, wooded, and coastal areas
- Consider submitting ticks for testing through the state lab after a bite
Simple takeaway
Tick season in Connecticut is starting earlier, with higher activity and increased disease risk—making prevention especially important this year.
