Mosquito Control Update

With temperatures finally on the rise after heavy rains, mosquito season is upon us and our field work has started. With people being home more than usual, residents may begin seeing Clarke (Village contractor) vehicles and crews in their neighborhoods. Here is what the Clarke teams are doing:

  • Inspecting standing water sites on public and private property (including backyards) where mosquitoes may breed. If mosquito larvae are found, a product is applied to prevent mosquito larvae from becoming biting adults.
  • Treating catch basins (storm drains) around town with an extended-control product. Fun fact - Clarke technicians ride bicycles while performing most catch basin treatments. 
  • Setting and checking traps that are used to monitor adult mosquito population levels. This helps determine when adult control treatments will be needed.


The Clarke Portal features a hotline for residents to report standing water sites and mosquito annoyance. Residents may also use the hotline to register for notifications by text or email before planned nighttime adult mosquito treatments.
