Distribution
Goldspotted Oak Borer (GSOB) infestations have spread throughout San Diego County since it's discovery in 2008. Satellite GSOB infestations were identified in Riverside County (2012), Orange County (2014) and Los Angeles County (2015). A second satellite infestation was discovered in south east Orange County in 2017. The latest GSOB satellite infestation was found in San Bernardino County (2019). All of these satellite infestations are believed to have occurred due to people transporting GSOB-infested firewood from known infested areas, such as San Diego County.
