What's eating my echeveria 'raindrops'?

Echeveria 'Raindrops' is an indoor succulent whose distinctive caruncle bumps can conceal early mealybug infestations. Mealybugs are the main pest; spider mites and vine weevil grubs are occasional secondary problems. Keep soil well-drained, inspect under the caruncles regularly, and isolate new arrivals before adding them to a collection.

White fluffy clusters hidden beneath or around the characteristic leaf bumps (caruncles); yellowing and softening of leaves. Carefully dab alcohol on each mealybug cluster with a cotton swab; treat with neem oil spray weekly for a month.

Pale stippling across leaf surfaces; fine silk webbing visible in bright light around the rosette. Remove webbing and wipe leaves with a damp cloth; spray with insecticidal soap or neem oil every 5–7 days for 3 weeks.

Plant wilts suddenly; grubs found in soil eating roots; notched leaf edges if adult weevils are present. Check roots when repotting; destroy grubs manually; apply nematode solution (Steinernema kraussei) to soil in spring and autumn.
