Lack 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.

Lack Township is 96% natural land cover (89% forest, plus open and brushy areas) across its 57.03 sq mi, home to about 623 people. That makes it the 1st-most wooded of the 17 towns in Juniata 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.

Juniata County reports about 140 Lyme cases per 100,000 people a year, the 100th-highest of 210 Northeast counties. That county-level disease pressure, combined with Lack Township's local habitat, sets how high its daily score can climb when the weather and season allow.
