Bronze Birch Borer: Systemic Protection for Birch and Neighboring Trees

The Pest

Bronze birch borer killed a white birch near the house. It primarily attacks birch, not structures. Neighboring birches will likely be affected.

Best Treatment

Bayer Advanced Tree & Shrub (imidacloprid/Merit) or Xytect (same AI) as soil drench gives 18-month protection. Treat all 18 trees on property. Systemic is superior to sprays for borers.
