What's eating my shoestring fern?
Mealybugs
Signs: White cottony clusters at the base of the narrow fronds; sticky honeydew and slowed growth
Control: Dab with alcohol-soaked cotton swab; apply diluted neem oil or insecticidal soap spray weekly
Spider mites
Signs: Fine webbing along fronds; fronds pale and wither in dry, warm air
Control: Raise humidity; spray with insecticidal soap or neem oil; repeat every 5–7 days
Fungus gnats
Signs: Larvae feed on fine roots in moist medium, stunting growth; adults swarm near substrate
Control: Allow top layer of substrate to dry slightly; drench with Bti solution; use yellow sticky traps

Shoestring Fern pests — FAQ
What is eating my shoestring fern?
Shoestring Fern (Vittaria lineata) has extremely narrow, grass-like fronds that can be colonized by mealybugs and spider mites in dry indoor conditions. Fungus gnats thrive if the moist, humus-rich substrate stays consistently wet. Its fine form makes early detection tricky — watch for webbing and check substrate moisture carefully.
