Mills Field & Sharp Park

Weather permitting, San Mateo County Mosquito and Vector Control District will conduct aerial mosquito larvicide applications over water at Mills Field (SFO) and/or Sharp Park lagoon in Pacifica. The treatments for 2023 are scheduled for July 10th, August 10th, September 12th, and October 9th. As usual, the schedule is subject to change due to weather conditions and mosquito abundance.

The product we’ll be using is a solid granular bio-rational mosquito larvicide; it targets mosquito larvae only and does not pose a risk to humans, pets, wildlife, fish, or the environment. It is applied by helicopter or unmanned aerial system (drone) in order to allow the product to reach the water in areas with dense vegetation, and to avoid the environmental impacts created by treating these areas on foot.

You may see or hear a helicopter or drone above or near the application area. At Mills Field there will be no closure of public areas. At Sharp Park, some sections of the levee along the west side of the golf course will be briefly closed (5-10 minutes at a time) to allow the helicopter to land safely; if a drone is used, no closures will occur. The golf course, beach, Mori Point, and the levee in general will NOT be closed.
