What's eating my echeveria 'tsunami'?

Echeveria 'Tsunami' features dramatically ruffled and wavy leaf margins — perfect hiding spots for mealybugs and thrips. Both pests exploit the folded edges. Spider mites follow in dry heated rooms. Root mealybugs can colonize the soil undetected. Its unusual leaf form demands close inspection during any routine pest check.

White fluff along the ruffled leaf margins and in the dense center; leaves yellow and deform Work isopropyl alcohol into the waves with a cotton swab; spray with neem oil solution weekly; repeat for 4–6 weeks

Silver-streaked scarring across leaf surfaces; tiny dark frass specks on and between leaves Apply spinosad-based insecticide or neem oil spray; remove and bag heavily infested outer leaves; repeat every 5 days for three rounds

Fine pale stippling on the fleshy leaves; webbing in the leaf folds in heavy infestations Spray with diluted insecticidal soap covering undersides of leaves; improve ventilation; treat every 5 days for three applications
