The Contra Costa County Mosquito & Vector Control District have announced they will be fogging by truck in Oakley Thursday night to control adult mosquitoes due to the high numbers of mosquitoes and the detection of West Nile in the area.
The announcement comes after the District confirmed that two sentinel chickens from Oakley and one dead bird from Danville have tested positive for West Nile virus. Fogging for adult mosquitoes is scheduled for Thursday evening in Oakley.
“To quote the late Yogi Berra, ‘It ain’t over till it’s over,'” said Steve Schutz, scientific program manager for the District referring to the mosquito season. “West Nile virus is still active, there is still a risk of contracting it from mosquitoes, and we all still need to take the necessary precautions to control mosquitoes and their bites.”
The fogging will begin 6:50 pm and continuing on through 10:00 pm (weather permitting). The area to be treated in Oakley is bordered on the north by Fetzer Lane and Monet Drive; on the east by Merganser Drive; on the south by West Cypress Road and East Cypress Road; and on the west by O’Hara Avenue and Soda Rock Place.
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.
Residents are urged to help reduce their risk of contracting mosquito-borne diseases by following these guidelines:
- Dump or drain standing water. Mosquitoes can’t begin their lives without water.
- Defend yourself against mosquitoes by using repellents containing DEET, Picaridin, or Oil of Lemon Eucalyptus.
- Avoid being outdoors when mosquitoes are present, typically dawn and dusk.
- Report neglected swimming pools by calling 925-771-6195 or visiting www.
ContraCostaMosquito.com Anonymous calls accepted. Just one neglected pool can produce more than 1 million mosquitoes and affect people up to five miles away. - Report dead birds to the state hotline: 1-877-968-2473. All reports are crucial, even if the bird does not meet criteria for testing.
Since 2005, 54 people in Contra Costa County have been diagnosed with West Nile virus. In 2006, two people died from the disease. Recent studies have shown that the majority of cases are not diagnosed and are grossly underreported. For 2015, a total of six groups of mosquitoes, nine birds,16 chickens and one horse have tested positive for the virus.
