Schefflera Arboricola Scale Infestation: Alcohol Spray vs Systemic

5-foot Schefflera arboricola, 1+ year. 3 months: sticky leaves falling, new growth present but leaves/stems sticky. Outdoor misting helped temporarily; stickiness returned.

Diagnosis

Sticky residue = insect excrement (honeydew). Plant would prefer full sun outdoors this season—stronger plants resist pests better.

Treatment Options

Spray regimen: 1 pint rubbing alcohol + 1 pint water + 1 tbsp dish detergent + 1 tbsp baby oil. Spray entire plant every 3 days consistently—lapses allow return.

Easier systemic: Bayer Tree and Shrub Protect and Feed (~$20 at Walmart/Lowes). Apply per label. Systemic: roots absorb, plant kills feeding insects and repels new for ≥1 year. 1 bottle treats 24+ plants. Used on ficus bonsai successfully.
