Sago Palm Scale: Identify, Scrape, Oil/Soap Treat

Diagnosis

Brown spots center of fronds, spreading, killing plant = scale insects. Flat oval/circular dots; suck sap; honeydew (ants may mask stickiness). Remove with fingernail → pale green spot.

Confirmation

Magnifier for tiny white crawlers (juveniles) on petioles/stems.

Treatment

• Large plants: Horticultural oil (temp-sensitive).
• Container/small: Toothbrush + soapy water physical removal. Then oil/soap spray.
• Both sides: Critical.

Oil Caveat

Oil suffocates but doesn't remove dead scales. Follow with high-pressure water (outdoor) or toothbrush (indoor).

Central Texas rain favors scale. Early, thorough treatment saves the sago.
