IT IS POSSIBLE TO PROTECT HIGH VALUE OAKS FROM THIS DEADLY INVASIVE BEETLE.
The Goldspotted Oak Borer (GSOB) is confirmed and killing oak trees near Lake Hodges. This is the beetle that has wiped out 100,000 Oaks in Julian. Big healthy trees are dying of GSOB attack, often in one to two years.
It is possible to protect high value oaks from this deadly invasive beetle with arborist treatment. Oaks need effective care to resist this bark boring insect.
SEVERAL RESIDENTS OF DEL DIOS AND MT ISRAEL ARE WORKING WITH AGUILAR PLANT CARE. THE COMPANY HAS THE EXPERIENCE AND LICENSING TO TREAT TREES FOR GSOB.
The best time to have oaks treated is between mid-April to mid-May, so we are a little behind for this year, 2017. It is recommended to have your trees evaluated and treated before the end of June or you are gambling on your tree’s health.
In January 2018 we will be doing more GSOB education and outreach about the pest and option to protect trees next spring. To receive notifications & updates, please sign up for our newsletter below.
