What’s the Gold Spotted Oak Borer?

The GSOB is a destructive insect pest that is decimating some oak species mostly in Southern California. It has been found infesting coast live oaks (Quercus agrifolia), California black oaks (Q. kelloggii) and canyon live oaks (Q. chrysolepis). It attacks the limbs of mature oak trees feeding in the conductive tissues and sapwood. Unfortunately the GSOB can be spread in cut firewood. Click here for additional information.
