Ticks 2025

Tick reports shows locations and counts of public-reported ticks in DuPage Co for the 2025 season. In addition to Lyme disease, ticks are a significant carrier of West Nile Virus (WNV). The DuPage Health Dept. utilizes a suite of maps - Tick Reports, Bird Deaths, and WNV - to help track WNV in the County to promote the awareness and education. These maps will be updated weekly throughout the season.
