Current Mosquito Activity & West Nile Surveillance

The South Cook County Mosquito Abatement District continuously monitors mosquito populations throughout the District using strategically placed surveillance traps. The interactive dashboard below provides current surveillance information, including mosquito trap locations, mosquito species collected, trap counts, and West Nile virus testing results.

Residents, public officials, researchers, and community partners can use this dashboard to better understand mosquito activity within the District and follow seasonal surveillance trends that help guide mosquito control operations.
