Shot Hole Borer Beetle Impacts

The Polyphagous Shot Hole Borer Beetle is originally from South East Asia and was discovered in Los Angeles in 2003.  As of fall 2014, the tiny black to brown beetle was found in over 200 species of trees, in particular oaks and sycamores.  The pest invasion throughout Southern California and Orange County has killed trees, created fire hazards, and threatened food production. The City is working with UC Riverside, which has taken the lead to find a way to battle the beetle, as well as with County organizations and homeowner associations to share information and track the beetle.  For more information visit the UC Riverside website at the link below.
