A helicopter working for County Vector Control will be
disbursing a granular mosquito larvicide this Wednesday, Sept. 26 at various
wetlands in the county, including the San Diego River in Santee.The larvicide contains bacteria which, while harmless to humans and wildlife, prevents mosquito larvae from reaching adulthood. The granules, which are about one-eighth of an inch long, “will not generate a fog, mist or cloud,” county officials said in a press release.
The larvicide drop is the seventh so far this year.
The aerial drops are aimed at preventing the spread of the West Nile virus and
other mosquito-borne diseases.
