The majority of the District’s mosquito control is completed when mosquitoes are still in their aquatic form, in their water source. Once mosquitoes emerge from the water as adults, the only effective method to control them is by fogging. We use only those products registered with the Environmental Protection Agency for the use of mosquito control and protecting public health. They are applied by our trained and certified technicians.
The Contra Costa Mosquito & Vector Control District announced mosquito fogging will occur tonight in the City of Brentwood.
Due to the detection of West Nile virus in mosquitoes in the area, the Contra Costa Mosquito & Vector Control District will be fogging by truck-mounted, ultra-low volume sprayers to control adult mosquitoes.
DATE: Monday, August 28, 2017
TIME: Between dusk (approximately 7:45 p.m.) and 11:30 p.m., weather permitting.
The area to be treated is bordered on the north by Balfour Road; on the south by Armstrong Way and Armstrong Road; on the east by Walnut Boulevard; and on the west by Crescent Drive.
MATERIALS USED: The insecticide to be used is Zenivex E4, RTU applied at a rate of 1.5 ounces per acre by truck-mounted, ultra-low volume sprayers.
The Contra Costa Mosquito & Vector Control District utilizes an integrated vector management program which means we use a variety of protocols for controlling mosquitoes. These protocols include public education, physical control such as managing vector habitat, biological control such as mosquitofish, and chemical control such as pesticides.
