These states are seeing their worst tick activity in nearly 10 years: Data

Tick activity is at its highest in nearly 10 years, with the CDC reporting a big uptick in tick-bite emergency visits this spring.
The Midwest and Northeast are being hit especially hard this year — many states there are seeing far above-average bite rates.
Tick season peaks in May–June; remove ticks promptly and watch for rashes or flu-like symptoms (seek medical care for severe reactions).
