Lightning-Struck Pin Oak Infested with Ambrosia Beetles: Assessment and Treatment Options

Immediate Steps

Lightning damage creates entry points for ambrosia beetles, which bore into stressed wood. The beetles themselves rarely kill a tree outright; they're a symptom of severe stress.

Professional Evaluation Needed

1. Contact your state forestry agency for a free forester visit to assess survival likelihood.
2. A certified arborist can evaluate structural damage from the lightning strike (bark loss up the trunk).
3. If the tree is deemed salvageable, the forester can recommend appropriate borer treatments.

On Fertilizer Spikes

Avoid high-nitrogen fertilizer spikes on a stressed tree; they can stimulate weak growth and attract more pests. Focus on wound care and monitoring.
