Persistent Scale on Spider Plant, Lime, Jade: Systemic + Alcohol Strategy

Scale returns despite sprays → need systemic + thorough contact.

Protocol

1. Murphy's Oil Soap + alcohol spray: 1 tsp each/quart; drench all surfaces.
2. Systemic granules (imidacloprid) in soil—6-8 week protection.
3. Repeat spray in 7 days.
4. Outdoor summer: Natural predators help.
5. Fall indoor: Treat before bringing in.

Key

Contact sprays miss hidden crawlers; systemic catches them. Combine both.
