San Joaquin County Mosquito and Vector Control District’s (District) mosquito-borne disease surveillance started a full trapping schedule this week. Starting this week, District personnel are placing sixty-five carbon dioxide-baited traps throughout San Joaquin County. Collected weekly, these strategic locations give the District a strong representative sample of the mosquito population, species activity, and mosquito-borne disease. With this data, when deemed necessary, the District increases mosquito control in any identified area, working to reduce the risk of mosquito-borne illness and protecting public health.
