Mealybugs
Signs: White woolly deposits at frond bases and crown; honeydew residue promoting mould
Control: Remove with isopropyl alcohol swabs; spray with insecticidal soap; isolate the plant and check weekly
Scale insects
Signs: Hard or soft bumps on petioles and rachis; slow yellowing and weakened fronds
Control: Scrape off manually; wipe with neem oil on a cloth; repeat every two weeks
Slugs and snails (outdoor/patio plants)

Macho Fern pests — FAQ
What is eating my macho fern?
Macho Fern (Nephrolepis biserrata) is a large, vigorous fern grown indoors or on sheltered patios. Its bold fronds are targeted by spider mites and mealybugs indoors, and scale can establish along its thick petioles. Outdoors, caterpillars and slugs may feed on frond edges. Its size makes infestations easier to spot and treat early.
