South Centre 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.

South Centre Township is 74% natural land cover (47% forest, plus open and brushy areas) across its 5.43 sq mi, home to about 1,911 people. That makes it the 22nd-most wooded of the 34 towns in Columbia 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.

Columbia County reports about 96 Lyme cases per 100,000 people a year, the 148th-highest of 210 Northeast counties. That county-level disease pressure, combined with South Centre Township's local habitat, sets how high its daily score can climb when the weather and season allow.
