Larvae sampling is conducted at over 175 sites documented throughout the county, including permanent and semi-permanent waters, retention ponds, sewage pump stations, ditches, stagnant pools, and human-created artificial water sources. In addition, residents reporting mosquito complaints or areas of concern were investigated as they were reported.
Collections that produce high larva counts trigger a control response based on the program's Integrated Mosquito Management (IMM) Plan. Treatment of the site includes using backpack sprayers dispensing the appropriate control material approved for use on the particular mosquito species and site.
