Ticks in Connecticut: what the public record shows

Before you compare quotes, it helps to know which ticks actually live in Connecticut, when they are busiest, and what the state figures look like. Everything below links to the agency or university page it came from.

3,239

Lyme disease cases reported, 2023

Counts are confirmed plus probable; high-incidence jurisdictions report on lab evidence alone, so cross-state comparisons favor the same year.

CDC

High-incidence jurisdiction (at least 10 confirmed cases per 100,000 for 3 years)

CDC Lyme surveillance classification

Lab-only reporting means counts here are higher and more complete than in low-incidence states.
