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

Downers Grove is 69% natural land cover (53% forest, plus open and brushy areas) across its 49.66 sq mi, home to about 147,793 people. That makes it the 8th-most wooded of the 39 towns in DuPage 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.

DuPage County reports about 4 Lyme cases per 100,000 people a year, in the top 21% of U.S. counties for reported Lyme disease. That county-level disease pressure, combined with Downers Grove's local habitat, sets how high its daily score can climb when the weather and season allow.
