The City of Crystal Lake's mosquito abatement program aims to: 

  • Monitor mosquito trap counts located throughout the community
  • Conduct community-wide mosquito spraying when trap count levels are too high
  • Conduct localized mosquito spraying before or during the Lakeside Festival
  • Posts mosquito information on newsletters, press releases, and social media
  • Decreases annoyance levels and the risk of West Nile Virus transmittal
