Southwest Greensburg Borough, 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.

Southwest Greensburg Borough is 25% natural land cover (22% forest, plus open and brushy areas) across its 0.39 sq mi, home to about 2,173 people. That makes it the 64th-most wooded of the 65 towns in Westmoreland 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.

Westmoreland County reports about 203 Lyme cases per 100,000 people a year, the 69th-highest of 210 Northeast counties. That county-level disease pressure, combined with Southwest Greensburg Borough's local habitat, sets how high its daily score can climb when the weather and season allow.
