PRODUCT DESCRIPTION

The goldspotted oak borer (GSOB) is an invasive beetle that attacks and kills mature oak trees. Beetle larvae bore under the bark and feed on and damage the trees' nutrient and water-conducting tissues. Trees die after several years of injury inflicted by multiple beetle generations. Experts believe the introduction of this non-native oak pest and subsequent spread throughout Southern California happened through the transport of infested  firewood. GSOB has killed tens of thousands of mature oak trees throughout San Diego County and in isolated areas of Orange, Los Angeles, Riverside, and San Bernardino Counties.
