Larval Mosquito Collections (April 1 to September 27)
Larvae sampling is conducted at over 175 sites documented throughout the county, including perminate waters, semi-perminate 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 are investigated as they arise.
Collections that produce high larva counts trigger a control response based on the program's Integrated Pest Management (IPM) Plan. Treatment of the site includes using backpack sprayers dispensing the appropriate control material approved for use on the particular mosquito species and site.
