The district contracts with Clarke, of St. Charles, Ill., to provide mosquito control throughout the district. Their services include:

  • Surveillance and Testing: Clarke monitors mosquito breeding habitats within the district and places traps to monitor mosquito populations, including for the presence of West Nile Virus.
  • Larval Control: Clarke uses Natular larvicide in breeding habits such as storm drains and retention ponds. The larvacide prevents mosquito larvae from maturing into adults. Natular is considered a Reduced Risk larvicide by the U.S. EPA, and is listed with the Organic Materials Review Institute.
  • Adult Control: Clarke uses Merus adulticide sprayed after sunset to reduce adult mosquito populations. Merus is USDA certified for use in and around organic farms and gardens.
  • Mosquito Hotline: Residents of the District can report of standing water lasting longer than three days or request service notifications for adult mosquito control applications at Please contact This email address is being protected from spambots.
