Spray Notification

As part of our Mosquito and Mosquito-borne Disease Management Plan we may implement ultra low volume (ULV) treatments by ground unit or by air in areas where disease has been detected.

Residents of Sacramento and Yolo counties can subscribe to our mailing list and receive an email notification for adult mosquito treatments by filling out the form below. We will make every attempt to notify individuals who sign up for our notification list via e-mail, however, we may not be able to notify the public if immediate applications are needed, or if technical difficulties prevent your email provider from receiving our messages. We may also cancel a scheduled operation due to weather conditions or other unforeseen reasons. The latest information is always posted on our Spraying Update page.
