Tonight: Adult Mosquito Control to Take Place in Oakley

The Contra Costa Mosquito and Vector Control District announced that due to the high number of mosquitoes and the detection of West Nile virus in the area, the Contra Costa Mosquito and Vector Control District will be using truck-mounted ultra-low volume equipment to control adult mosquitoes.

• DATE: Friday, August 9, 2024
• TIME: Between dusk (approximately 8:30 p.m.) and 11:00 p.m., weather permitting.
• LOCATION: Big Break Regional Trail, Oakley
• The area to be treated is Big Break Regional Trail from Piper Ln. on the west to Marsh Creek on the east and behind the homes bordering Ironhouse Sanitary District property.

MATERIALS USED: The public health pesticide to be used is Zenivex E4 RTU applied at a rate of 1.5 ounces per acre by truck-mounted ultra-low volume equipment.

The Contra Costa Mosquito and 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 including managing vector habitat, biological control such as mosquitofish, and chemical control such as public health pesticides.

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 adult mosquito control. We use only those products registered with the Environmental Protection Agency (EPA) and California Department of Pesticide Regulation (DPR) for the use of mosquito control and protecting public health. They are applied by our trained and certified technicians according to label instructions.
