Twig Girdler on Prize Oak: Sanitation Saves Next Year

Old twin oak dropping twig clusters—twig girdler/pruner. Will it kill tree? How to save?

No, It Won’t Kill

Insects lay eggs in twigs, girdle them, twigs fall. Larvae overwinter in fallen twigs.

Control: Sanitation

• Gather and destroy (burn/chip) ALL fallen twigs promptly.
• Next year’s population crashes.
• Tree unaffected long-term.

Clean up now; enjoy the oak.
