What's active right now
Deer-tick nymphs are tapering as lone-star seed ticks swarm where that tick is established. Late-summer risk stays meaningful in brushy, wooded areas. Where the lone star tick lives (coastal and southern areas), aggressive larval 'seed tick' swarms peak now.
Local tick habitat
Crystal Lake is 88% natural land cover (70% forest, plus open and brushy areas) across its 35.5 sq mi, home to about 464 people. That makes it the 3rd-most wooded of the 19 towns in Marquette 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.
Marquette County reports about 404 Lyme cases per 100,000 people a year, in the top 1% of U.S. counties for reported Lyme disease. That county-level disease pressure, combined with Crystal Lake's local habitat, sets how high its daily score can climb when the weather and season allow.
