Polynesian Davallia pests — FAQ
What is eating my polynesian davallia?
Polynesian Davallia is a houseplant fern grown for its fuzzy rhizomes, most threatened by scale insects that colonize both fronds and exposed rhizomes. Spider mites attack fronds in dry air. Mealybugs hide in rhizome crevices. Inspect the woolly rhizomes closely as they conceal pests better than smooth-stemmed ferns.
