Treatment Updates

As part of our Vector-borne Disease Management Plan we may implement ultra low volume treatments by ground or air in areas where vector populations are unusually high or where disease has been detected.

Subscribe to our email updates and you will receive emails about mosquito treatments in your area. We will update those who sign up as soon as we know treatment is scheduled although we may not be able to notify the public if immediate applications are needed. We may cancel scheduled operations due to weather conditions or other unforeseen reasons. You can also follow us on Facebook, Twitter, Instagram or Nextdoor for other District updates.
