Tick risk near you today

Live scores in all 50 states, from Down East Maine to the California coast, the Rocky Mountains, Alaska, and Hawaii.

How TickZone works

One daily number

A single 0–100 score with a green, amber, or red band. Know at a glance, not after reading a report.

A 7-day outlook

Risk recalculates every day from the local forecast, so you can plan the hike, the yard work, the dog walk.

See what's driving it

Weather, tick life-stage, local habitat, county disease rates, and which tick species live in your county: all shown, never hidden.

Sourced and honest

Built from public health and mapping data, and clear that it's a defensible heuristic, not a medical diagnosis.
