Due to the high numbers of mosquitoes, the Contra Costa Mosquito & Vector Control District will be fogging by truck Thursday, September 11 to control adult mosquitoes.
The area to be treated is bordered by Old River on the east; by unincorporated agricultural land access roads on the west; by Indian Slough on the north; and by unincorporated agricultural land access roads on the south.
This area will be fogged between the hours of 7:45 p.m. and 11:30 p.m., weather permitting.
MATERIALS USED:
The insecticide to be used is Pyrocide 7067 applied at a rate of .75 ounces per acre by truck-mounted, ultra low volume sprayer.
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.
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 using pesticides. 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.
