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

River Forest is 69% natural land cover (65% forest, plus open and brushy areas) across its 2.48 sq mi, home to about 11,227 people. That makes it the 20th-most wooded of the 148 towns in Cook 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.

Cook County reports about 2 Lyme cases per 100,000 people a year, in the top 22% of U.S. counties for reported Lyme disease. That county-level disease pressure, combined with River Forest's local habitat, sets how high its daily score can climb when the weather and season allow.

How much does tick control cost in River Forest?
