Summary
One batch of mosquitoes collected June 8 in Northbrook tested positive for West Nile virus in NSMAD's lab on June 9, marking the village's first positive mosquitoes of 2026.
The North Shore Mosquito Abatement District said infection risk remains low for now, but urged residents to use EPA-registered repellent, wear loose-fitting clothing and avoid dawn and dusk exposure.
Standing water remains the main local control target, with residents asked to empty small containers and other overlooked items where mosquitoes can breed.
Evanston has also recorded West Nile-positive mosquitoes in NSMAD traps this year, indicating the virus is already circulating elsewhere in the district.
