Taiwan Felt Fern pests — FAQ
What is eating my taiwan felt fern?
Taiwan Felt Fern (Pyrrosia polydactyla) is a compact epiphytic houseplant whose felt-textured fronds attract mealybugs hiding in crevices and scale insects along rhizomes. Spider mites can colonise the undersides in dry indoor conditions. Mealybugs are the most frequently reported pest, sheltering in the dense felt where sprays struggle to penetrate.
