Williamsport, 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.

Williamsport is 50% natural land cover (35% forest, plus open and brushy areas) across its 8.78 sq mi, home to about 27,470 people. That makes it the 51st-most wooded of the 52 towns in Lycoming 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.

Lycoming County reports about 110 Lyme cases per 100,000 people a year, the 132nd-highest of 210 Northeast counties. That county-level disease pressure, combined with Williamsport'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 Williamsport, today's risk reads low (33/100). Tick activity is low right now, but never zero. A quick check after time outdoors is still worth it.
