Ticks and Tick-Borne Diseases Are Increasing Upstate

By Annette Pinder

According to nyticks.org, the New York Post, and SUNY Upstate Medical University (SUNY Upstate), the tick population in upstate New York is rising sharply. A citizen-submitted tick testing program at SUNY Upstate reported 322 ticks sent in between mid-March and early May 2025, reflecting a 217% increase compared to 2024. In Central New York, labs have seen a 200% rise in tick submissions by mid-June 2025 compared to 2024.

The proportion of ticks carrying diseases has also increased. In early 2025, 38% of ticks tested positive for at least one pathogen — up from about 35% in 2024 — with a notable spike in anaplasmosis-carrying ticks. Rates have risen for Lyme disease, babesiosis, and anaplasmosis, all of which are found in roughly one-third of submitted deer ticks. According to nyc.gov, warmer winters and earlier springs upstate create better conditions for tick survival and longer periods of activity. Extended warm and wet seasons help ticks grow faster and thrive. Additionally, as people spend more time outdoors, they’re more likely to encounter ticks.

To prevent yourself from tick encounters or contracting a tick-borne disease:

  • Check yourself and your pets thoroughly after spending time outdoors, especially in wooded or grassy areas.
  • Remove ticks promptly with fine-tipped tweezers.
  • Submit ticks to labs (like Upstate’s) — you’ll help monitor trends and identify risks. Call 970-305-5587 to learn more.
  • Preventive measures at home include clearing brush and leaf litter, installing woodchip or gravel barriers, and using EPA-approved tick repellents.

In short, ticks and tick-borne pathogens are increasing in upstate areas, and vigilance — through prevention, monitoring, and early detection — is your best defense.
