Persistent White Scale on Sago Palm Fronds: Systemic Treatment Is Best

The Challenge

Flea/tick spray and malathion failed to control scale on sago fronds.

Scale insects protect themselves under waxy covers; sprays rarely penetrate. Dead scales also stay attached, making it look like treatment failed.

Systemic soil drench: Bayer Advanced Tree & Shrub Insect Control (imidacloprid) applied to soil. Roots absorb it; feeding scales die over weeks.
Follow‑up: Monitor for new scale on fresh growth—old shells won’t fall off.
Alternate sprays: Orthene (acephate) or insecticidal soap for crawler stage, but systemic is easier and longer‑lasting.

Read labels; ensure product is labeled for cycads/sago palms.
