Grand Isle, VT

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.

Grand Isle is 83% natural land cover (48% forest, plus open and brushy areas) across its 16.41 sq mi, home to about 2,135 people. That makes it the 3rd-most wooded of the 5 towns in Grand Isle 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.

Grand Isle County reports about 255 Lyme cases per 100,000 people a year, the 53rd-highest of 210 Northeast counties. That county-level disease pressure, combined with Grand Isle's local habitat, sets how high its daily score can climb when the weather and season allow.
