Mosquitoes are the target of West Nile virus fogging that begins in Brentwood on July 19.
An area of Brentwood will be fogged Thursday night as part of an ongoing mosquito control effort to prevent the spread of the West Nile Virus.
Contra Costa Mosquito and Vector Control District crews plan to fog this part of Brentwood due to a high number of mosquitoes and the recent detection of the virus in the area, district officials said.
From 8:30 p.m. to 11 p.m. Thursday, a fogging truck will pass through an area of town bordered by Sand Creek Parkway on the north, by Sellers Avenue on the east, by Independence Street and Guthrie Lane on the south and by Brentwood Boulevard on the west.
An insecticide called Pyrocide will be used to spray this area at a rate of 0.75 ounce per acre, according to the vector control district.
District officials say the spray is registered with the Environmental Protection Agency for the treatment of adult mosquitoes and protecting public health and will be applied by trained, certified vector control technicians.
Those who are bit by mosquitoes carrying the West Nile Virus may experience mild to severe flu-like symptoms including fever, headache and body aches.
In severe cases, the virus can affect the nervous system and may cause coma, convulsions or paralysis. People over 50 years old or with compromised immune systems are at higher risk of developing a severe illness from the virus.
However, most people who are infected with the virus will not develop any type of illness, according to the Centers for Disease Control and Prevention.
