Hong Kong Orchid Tree Borer: Systemic Insecticide Treatment

Hong Kong orchid tree (Bauhinia blakeana) with borer in branches (trunk OK): only systemic insecticide reaches larvae inside wood.

Treatment

• Bayer Advanced Tree and Shrub Insecticide soil drench per label.
• Systemic uptake kills internal feeders.
• Provides 12-month protection.
• Slows damage; may not reverse existing extensive tunneling.

Additional

• Prune out heavily damaged branches.
• Keep tree vigorous with water and fertilizer.

Early treatment is critical; advanced borer infestations are often fatal.
