Chesterfield, NY

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.

Chesterfield is 98% natural land cover (93% forest, plus open and brushy areas) across its 79.03 sq mi, home to about 2,442 people. That makes it the 13th-most wooded of the 18 towns in Essex 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.

Essex County reports about 326 Lyme cases per 100,000 people a year, the 32nd-highest of 210 Northeast counties. That county-level disease pressure, combined with Chesterfield'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 Chesterfield, today's risk reads high (70/100). Conditions strongly favor tick activity. Cover up, use repellent, and check carefully, including kids and pets.
