In San Diego, the Gold Spotted Oak Borer (GSOB) has caused a lot of damage to oak trees. It is a beetle originally from Southeastern Arizona. Since it appeared, the death rate of oak trees has increased, affecting both private and public lands. The biggest issue is the cost of dealing with the oak tree borer. The loss of many oak trees has affected the natural landscape.
Female GSOB beetles lay eggs in the cracks of oak trees, and the adults feed on the tree’s leaves. Beneath the bark, you can find the larvae or pupae of red oak borer. Signs of an infested tree include:
- A thinning crown
- Stains on the bark
- D-shaped holes
- Bark damage
It is very important to identify infested trees early to stop the spread of the beatles. Arborists at Tree Doctor USA will provide you with experts who will treat GSOB-infested oak trees. They put insecticides in the soil or trunk to manage the pest safely and effectively.
