Ticks don't jump or fly — they wait on tall grass and brush and latch onto a passing host, which is why yard treatment (especially along the edges where lawn meets woods or brush) is the effective control point, not just personal repellent.
Ticks are a genuine disease vector — Lyme disease is the most well-known, but regional risk varies significantly by species and location, and county-level tick establishment genuinely differs even within a state. The CDC's national tick surveillance program publishes county-level blacklegged tick status maps precisely because this varies so much locally — worth a look for your specific county before assuming your regional risk based on state alone.
