USA tick resources — fast navigation

Last updated: January 24, 2026

This hub organizes USA tick guidance into state pages. Each state page focuses on:

  • Common local tick species (high-level; links to official sources)
  • Seasonality notes (practical vigilance guidance)
  • Dominant pathogens (high-level, careful wording)
  • Official state resources (maps, surveillance, and what to do after a bite)

Key takeaways

  • Risk is local: county-level risk can vary dramatically within a state.
  • Use CDC + your state: follow CDC fundamentals, then defer to your state health department for local guidance.
  • Prompt removal helps: remove ticks as soon as you find them and monitor for symptoms.
