What's eating my astroloba corrugata?

Astroloba corrugata shares the pest profile typical of haworthioid succulents kept indoors. Mealybugs are the primary threat, hiding between the corrugated leaves. Root mealybugs can develop silently in poorly drained soil. Spider mites become problematic in dry, warm rooms with low humidity.

Cottony white residue between tightly packed leaves; honeydew; leaves yellow or collapse Dab with isopropyl alcohol; spray neem oil solution weekly; keep plant isolated until clear

Unexplained wilting and decline; white powdery coating on roots found at repotting Unpot, rinse roots, allow to dry, drench soil with diluted neem or use a systemic insecticide; repot fresh

Fine webbing at leaf tips; silvery stippling on leaf surfaces; plant looks dull and dry Raise humidity around plant; rinse foliage; apply miticide or neem oil every 5–7 days for 3 cycles
