Mealybugs on Dracaena: Treatment Options

Tiny white cottony masses on dracaena leaves and stems are mealybugs. Wipe off what you can, then spray thoroughly with insecticidal soap or a pyrethrin-based houseplant insecticide. Repeat applications at monthly intervals may be needed.

Systemic granules (like Bonide Systemic Houseplant Insecticide) are very effective but toxic to pets—avoid if dogs or cats might lick the soil.
