Persistent Scale on Vines: Systemic Imidacloprid Solution

Two-Year Battle with Scale on Vines in Chicago

Scale insects resisting contact sprays. Best solution: Bayer Advanced Tree & Shrub Insecticide (imidacloprid) soil drench per label. Systemic action kills scale in 1–2 weeks, protects 8+ months.

Why It Works

Contact sprays miss scale under waxy covers.
Systemic moves through vine’s vascular tissue to feeding sites.
One application per season usually sufficient.

Apply in early spring as growth resumes. Follow label for rate based on vine size.
