mealybugs on Yucca
Quick answer
If your Yucca has mealybugs, the most likely cause is: Yucca elephantipes keeps its broad, dark green leaves in dense rosettes at the top of a woody trunk, and standard houseplant references list mealy bugs alongside aphids, scale insects and spider mites among the pests and diseases of Yucca elephantipes grown indoors.
Start here:
- 1. Inspect the leaf axils and the undersides of the sword-shaped leaves on a regular schedule, because mealy bugs hide where the foliage meets the trunk and can be wiped off with a cotton swab dipped in rubbing alcohol before they spread across the rosette.
- 2. Isolate the affected yucca from other houseplants while you treat it and repeat the inspection and swabbing until no fresh white, waxy tufts appear, since mealy bugs recur quickly on indoor specimens.
