What's eating my caladium 'fannie munson'?

Caladium 'Fannie Munson', a tropical houseplant prized for its vivid pink-veined foliage, is most commonly troubled by spider mites, which thrive in dry indoor air. Mealybugs colonise leaf axils and petioles. Thrips scar the paper-thin leaves. Fungus gnats infest wet compost. Keep humidity high to deter mites.

Fine webbing on leaf undersides; pale yellow stippling or bronzing across the leaf surface; leaves may crisp and drop Mist foliage regularly and raise ambient humidity; apply insecticidal soap or neem oil spray, repeating every 5–7 days; quarantine affected plants

White waxy cottony clusters at petiole bases and leaf axils; sticky honeydew and stunted growth Dab colonies with isopropyl alcohol on a cotton swab; spray the whole plant with neem oil; treat systemic infestations with imidacloprid

Silver-grey streaking and tiny dark frass spots on the delicate leaf surface; distorted or bleached new leaves Isolate the plant immediately; apply spinosad or insecticidal soap spray; use yellow sticky traps; repeat treatments every 5 days for three cycles

Larvae damage fine roots in wet compost, slowing growth; adults emerge annoyingly from the soil surface Let the top 2 inches of compost dry before watering; use yellow sticky traps for adults; apply Bacillus thuringiensis var. israelensis (Bti) drench or beneficial nematodes
