Instead of treating the entire spray blocks (crosshatched areas numbered on the map), only the hotspots with the mosquito larvae identified by weekly surveillance were treated resulting in much smaller treatment footprint (violet colored blocks) on the marsh. The 2018 aerial applications were targeted toward areas with heavy mosquito breeding.
