Rochester Township, PA

Nymphs are questing, the highest-risk stage for people. Nymphal deer ticks peak in late spring and summer. They're the size of a poppy seed, easy to miss, and cause most Lyme transmission.

Rochester Township is 92% natural land cover (79% forest, plus open and brushy areas) across its 3.88 sq mi, home to about 2,721 people. That makes it the 22nd-most wooded of the 54 towns in Beaver County. Deer ticks live in wooded areas, along trail edges, and in tall grass — the more of that a town has, the more places ticks can quest.

Beaver County reports about 73 Lyme cases per 100,000 people a year, the 165th-highest of 210 Northeast counties. That county-level disease pressure, combined with Rochester Township's local habitat, sets how high its daily score can climb when the weather and season allow.
