What's eating my hairy jovibarba?

Hairy Jovibarba is a tough alpine succulent grown indoors and rarely troubled by pests. Mealybugs are the most likely attacker, hiding in the dense rosette. Vine weevil grubs can silently destroy roots. Overwatering-induced fungus gnats are common. The rosette's tight structure and waxy leaves repel most insects.

White cottony tufts nestled between leaves; sticky honeydew; distorted new growth Dab individual bugs with a cotton swab dipped in 70% isopropyl alcohol; follow up with neem oil spray for 2–3 weeks

Plant suddenly collapses; roots and stem base eaten away underground Unpot, wash off soil, inspect and remove creamy C-shaped grubs; repot in fresh grit-rich mix; apply pathogenic nematodes (Steinernema kraussei) in spring

Tiny flies hovering around compost; larvae nibble fine roots, causing pale, wilting growth Let the top 2 inches of soil dry completely between waterings; use sticky yellow traps; apply Bacillus thuringiensis israelensis (Bti) drench
