Mealybugs on Palm Plants: Identification and Treatment

White Fuzzy Stuff on Palms = Mealybugs

The white, powdery, cocoon-like substance on palm stalks and leaves is almost certainly mealybugs. Compare to mealybug images.

Rubbing alcohol spray: Straight or diluted in spray bottle. Drench all surfaces (leaf crotches, undersides, soil surface) daily for 1 week, then twice weekly for 3 weeks.
Neem oil: Per label instructions. Available at Lowe's/garden centers.

Persistence. Mealybugs hide in crevices. Complete, repeated coverage is essential. They do not harm humans.

If webs are extremely fine, consider spider mites—but mealybugs match "white fuzzy cocoon" better.
