Welcome to the DNREC Mosquito Control Section's new Spray Zone Notification System. To better communicate our scheduled pesticide applications, the Mosquito Control Section has partitioned the state into numbered spray zones. These numbered zones will be identified on a daily basis when spray activity is planned within a particular zone or zones. Please note: Zones identified to be sprayed only indicate that spray operations are planned within that area, not that the entire zone(s) will be sprayed.

The Spray Zone Notification System uses a spray zone map and a Delaware notification service to identify zone(s) where pesticide applications are scheduled:

  1. Spray Zone Map - This online map will be updated daily (by 4 p.m.) to identify zones where pesticide applications are scheduled. This map can also be used as a tool to identify a zone number for a particular property.
  2. Delaware Notification Service - Once registered, this service will allow individuals to be immediately notified, via text, phone, or email, of upcoming spray activities in a particular zone(s).

To use the Spray Zone Notification System:


  • Navigate to the Mosquito Control Section Spray Zone Map

  • Using the map, identify the zone number(s) associated with a particular property or area for which you would like notification for when spray activities are scheduled.

    To assist with zone identification, a search box is provided above the map to locate a specific address. The zone number is the black number displayed on the map.


  • Navigate to the Delaware Notification Service registration page

  • Once there, first-time users should click on "Sign Me Up" under the login fields to register with the the Delaware Notification Service. Choose your options for receiving messages (via text, phone, and/or email) when you register.

  • Once registered, log onto the Delaware Notification Service with your username and password.

  • Click on your name at the top of the page and go to "Subscriptions."

  • Click on the "Manage Subscriptions" tab. 

  • Click on the arrow next to "DNREC-MOSQUITO CONTROL" to expand a list of zones.

  • To receive notification of spray activities within a particular zones, select the box next to the zone(s) that you identified in STEP 1 above.
    • To receive notification of all spray activities statewide, select the box next to "Mosquito Control Statewide Spray Announcement."

    • Click SAVE at the bottom of the page

    Once these steps are completed, you will receive notification via text, phone, or email (depending on your selection in the Delaware Notification Service) whenever spray activity is scheduled within your selected zone(s).
