Harrison 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.

Harrison Township is 92% natural land cover (66% forest, plus open and brushy areas) across its 36.4 sq mi, home to about 1,009 people. That makes it the 27th-most wooded of the 30 towns in Potter 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.

Potter County reports about 550 Lyme cases per 100,000 people a year, the 9th-highest of 210 Northeast counties. That county-level disease pressure, combined with Harrison Township's local habitat, sets how high its daily score can climb when the weather and season allow.

Yes. Nymphs are questing, the highest-risk stage for people. In Harrison Township, today's risk reads high (74/100). Conditions strongly favor tick activity. Cover up, use repellent, and check carefully, including kids and pets.
