What's eating my cretan climbing fern?

Cretan Climbing Fern (Lygodium microphyllum) kept indoors is susceptible to spider mites and mealybugs, which exploit its delicate climbing fronds. Fungus gnats can be problematic if the growing medium stays too moist. Its fine-textured foliage makes pest outbreaks easy to miss until damage is widespread.

Tiny pale dots and webbing on leaflets; fronds become bleached and dry-looking Mist foliage to raise humidity; spray with insecticidal soap or neem oil; isolate from other plants

White cottony deposits along stems and leaf joints; stunted, distorted new growth Dab infested spots with alcohol-soaked cotton; follow with neem oil spray repeated weekly

Larvae damage fine roots in moist substrate; adults are a nuisance but larvae cause actual plant stress Allow soil surface to dry between waterings; apply Bacillus thuringiensis israelensis (Bti) drench; use sticky yellow traps
