Mosquito & Integrated Pest Management (IPM)

Updated 2/27/2026

Mosquito Control

Larval control operations will start in April and will continue for the 2026 season.  Adult control operations will begin when action thresholds are met. During mosquito season, fogging will take place Sunday through Thursday, when weather allows, on a rotating basis among our three zones: North, South/APO, and West. Depending on adult mosquito activity, the rotation will function normally, but fogging operations will be scaled to the perimeter zones. For more information on the zones, please check out our map on the Hotline tab
