De Kalb, 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.

De Kalb is 88% natural land cover (65% forest, plus open and brushy areas) across its 82.52 sq mi, home to about 2,343 people. That makes it the 21st-most wooded of the 33 towns in St. Lawrence 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.

St. Lawrence County reports about 153 Lyme cases per 100,000 people a year, the 95th-highest of 210 Northeast counties. That county-level disease pressure, combined with De Kalb'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 De Kalb, today's risk reads moderate (50/100). Ticks are active. Use repellent, stick to trails, and do a tick check when you come inside.
