Lone Star Tick Awareness Map
Where Lone Star ticks are reported across the United States, drawn from published distribution data. Search your ZIP, drag to explore, and open any state or county for peak season, prevention, and what to do after a bite. These are educational awareness levels — not official surveillance, and not any individual's medical risk.
Drag to pan, or focus the map and use the arrow keys. Press plus and minus to zoom, and 0 to return to the whole country. Tab moves to a state; the arrow keys then step between states and Enter opens one.

What the colours meanShowHide
Awareness level
How widely Lone Star ticks are reported in each state.
Low
Not currently considered established here — few or no Lone Star tick reports in public data.
Emerging
Reports are increasing at the edge of the documented range.
Established
Inside the documented Lone Star tick range.
High Awareness
Inside the documented range, and among the states with the most reported alpha-gal cases.
Limited public data
No usable public data for this area — that is not the same as low risk.
These are educational awareness levels drawn from published tick-distribution data — not official surveillance, and not any individual's medical risk.
Tick presence does not equal disease risk
The presence of Lone Star ticks in an area does not mean a bite will transmit disease or cause alpha-gal syndrome. This map is a reminder to take prevention steps where ticks are active. For region-specific guidance, open your state page or contact your state health department.
