What's eating my alocasia wollongong?

Alocasia Wollongong is most threatened by spider mites, which thrive in the dry indoor air this tropical needs. Mealybugs, scale insects, and thrips also target it. Inspect the dramatic arrow-shaped leaves weekly — catching infestations early with neem oil or insecticidal soap keeps this cultivar healthy.

Fine webbing on leaf undersides; leaves develop yellow stippling and lose their deep-green sheen Raise humidity, wipe leaves with a damp cloth, and spray with diluted neem oil or insecticidal soap every 5–7 days until clear

White cottony clusters at leaf axils and stem joints; sticky honeydew leads to sooty mold Dab colonies with a cotton swab dipped in 70% isopropyl alcohol; follow up with neem oil spray for 2–3 weeks

Brown or tan waxy bumps on stems and petioles; leaves yellow and growth stalls Scrape off with a soft toothbrush, then apply horticultural oil or insecticidal soap; repeat every 10 days

Silver-streaked or bronze scarring on leaf surfaces; tiny dark frass specks visible on undersides Isolate the plant, remove heavily damaged leaves, and apply spinosad-based spray or insecticidal soap weekly for 3–4 weeks
