What's eating my duvalia caespitosa?

Duvalia caespitosa is a clumping stapeliad succulent kept indoors. Mealybugs are its most common pest, lodging between the tightly packed stems. Root mealybugs can devastate the root system undetected, and fungus gnats thrive if the soil stays too moist. Keep the growing medium well-drained to reduce risk.

White waxy fluff between clustered stems; honeydew and sticky residue; stunted new growth Isolate plant; treat colonies with isopropyl alcohol swabs; spray with dilute neem oil solution weekly

Progressive wilting and yellowing despite good care; white powder found on roots at repotting Remove old soil entirely, soak bare roots in insecticidal drench, repot in fresh gritty succulent mix

Tiny flies around soil; larvae chew fine roots causing wilting and poor vigour Allow soil to dry fully between waterings; use yellow sticky traps; drench with Bacillus thuringiensis israelensis (Bti)
