Goldspotted Oak Borer

Moving oak firewood has the potential to introduce this new pest to more California locations. Preventing movement of infested wood (primarily firewood) to new areas is essential for slowing the spread of this exotic borer to other regions of the state. Wood from infested trees should be kept within several miles from its origin and never moved outside of the current area of GSOB establishment in San Diego County.
