West Vincent 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.

West Vincent Township is 91% natural land cover (63% forest, plus open and brushy areas) across its 17.68 sq mi, home to about 6,852 people. That makes it the 22nd-most wooded of the 73 towns in Chester 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.

Chester County reports about 140 Lyme cases per 100,000 people a year, the 101st-highest of 210 Northeast counties. That county-level disease pressure, combined with West Vincent Township's local habitat, sets how high its daily score can climb when the weather and season allow.
