Where Do Ticks Actually Live in the US?
Ticks have confirmed sightings in 49 US states, based on 99,936 verified occurrence records.
By Tim, founder of Easy Street Markets. I maintain the wildlife database and verify every animal and source myself.
The states with the strongest confirmed populations are Alabama, Alaska, Arizona, Arkansas, California and Colorado, and 43 more. These are real, verified iNaturalist and GBIF occurrence records, not modeled range estimates.
A small number of states (1) have only a handful of unverified or vagrant records, too few to confirm ticks as an established population there.
