Japanese Beetle on Crimson King Maple: Control Options

Pest Identification

The beetle skeletonizing leaves on your newly planted Crimson King maple is a Japanese beetle (Popillia japonica)—metallic green/copper, ~½ inch long.

Control Options

Immediate (Foliar Spray)

Spray Orthene (acephate) thoroughly on all foliage. Systemic action helps, but reapplication may be needed.

Season-Long Systemic (Preferred)

Apply Bayer Advanced Tree & Shrub Insect Control (imidacloprid) as a soil drench. Roots distribute insecticide to leaves—beetles die when feeding. One application protects all season.

Product: Bayer Advanced Insect Control

Why Soil Drench Wins for New Trees

• No spray drift or phytotoxicity risk on tender leaves.
• Covers entire canopy, including new growth.
• Easier application—no ladder or sprayer needed.

Treat now; the systemic will protect remaining foliage and next year's growth if applied annually in spring.
