Scale Infestation on Ficus: Thorough Treatment Protocol

Tiny black bugs and gray spots causing defoliation on your ficus are scale insects—immobile, sap-sucking pests with protective shells. The gray spots are the scale.

Treatment Protocol (Repeat Twice, 5–7 Days Apart)

1. Prune leggy branches first—easier coverage, stimulates growth.
2. Spray thoroughly until dripping: all leaf surfaces (top/bottom), stems, trunk.
3. Choose one:
   • Rubbing alcohol mix: 1 part alcohol : 8–10 parts water + few drops dish soap.
   • Horticultural oil (Sun Spray Ultra Fine) per label.
   • Hot Pepper Wax (cayenne-based) per label.
   • Neem oil + Pine Sol (for odor) per label.
4. Repeat full treatment in 5–7 days for crawlers.
5. Inspect weekly thereafter.

Critical Rules

• Never apply in direct sun or high heat.
• Complete coverage is essential—missed spots = reinfestation.
• Treat all nearby plants preventatively.

Persistence eliminates scale. Ficus recovers vigorously after pruning and treatment.
