A Message From Clarke Mosquito Control: Preparing for an Active Mosquito Season
The 2026 mosquito season is getting underway across the Chicagoland region — and an exceptionally wet start to the year is setting the stage for an active season. Our program focuses on protecting public health by minimizing vector disease risk, particularly West Nile Virus (WNV), while proactively managing early-season mosquito populations.
The Chicagoland area recorded its seventh wettest April on record this year, with precipitation running more than three inches above normal. That abundant moisture, a sharp contrast to the drought conditions that defined much of 2025, means significantly more standing water and breeding habitat available to floodwater mosquitoes as the season begins. Combined with above-normal temperatures, conditions are ripe for early and active mosquito activity.
Clarke encourages residents to get ahead of the season by practicing the three “R’s” (Reduce, Repel, Report) and to report stagnant water locations through the Clarke Portal at www.clarkeportal.com/hotline.
