Aerial Mosquito Larvicide Application


Last updated 9/28/2016 at 11:19am

The County of San Diego Vector Control Program (VCP) will conduct its eighth aerial mosquito larvicide application of the 2016 mosquito season at large waterbodies known to breed mosquitoes throughout the county on Wednesday, October 05, 2016.

A helicopter will apply larvicide to reduce mosquito populations and reduce the risk of West Nile virus (WNV) transmission. The larvicide is made of naturally occurring bacteria which target mosquito larvae in the water and is not toxic to people, pets, fish or other insects. This reduces the number of mosquitoes that can spread diseases such as West Nile virus. VCP staff will be at the locations during the application to answer questions and monitor progress.

Additional larvicide applications will be conducted at three to four week intervals or as needed through the end of the mosquito season which is approximately October. Mosquito populations are monitored and tested for the presence of West Nile virus and other mosquito-borne diseases throughout the county.
