Aerial Mosquito Control Planned In Oceanside: June 23-24

OCEANSIDE, CA — The County of San Diego Vector Control Program (VCP) will conduct mosquito larvicide applications to reduce mosquito breeding and decrease the risk of West Nile virus (WNV) transmission.

The Oceanside area will be included in the third routine aerial application of the 2021 season scheduled for June 23-24. The mosquito-fighting aerial larvicide drop will target nine Oceanside waterways.

Aerial Larvicide Applications Locations in Oceanside include approximately 270 acres in these waterway areas:

• Buena Vista Lagoon
• Fireside Park
• San Luis Rey River
• Huula Dr.
• Foss Lake
• Libby Lake
• Talone Lake
• Guajome County Park
• Antique Gas/Guajome Adobe

To better protect our communities and the environment, the Vector Control Program (VCP) applies mosquito larvicide via helicopter to mosquito breeding areas that cannot be treated by hand. These aerial applications occur every three to four weeks during the mosquito breeding season, generally April to October, or as needed.

The granular larvicides used by the Vector Control Program act specifically on mosquito larvae and will not harm people, pets, plants, or wildlife. The larvicide consists of granules containing Lysinibacillus (Bacillus) sphaericus, Bacillus thuringiensis israelensis, and/or Saccharopolyspora spinosa products. These naturally occurring bacteria target mosquito larvae and prevent them from developing into biting adults.

Larvicides Used for Control of Mosquito Larvae:

• Natular Label
• Natular SDS
• VectoMax Label
• VectoMax SDS
• Fourstar Label
• Fourstar SDS
• VectoBac GR Label
• VectoBac GR SDS
