What is eating my scarlet ball cactus?
Scarlet Ball Cactus (Parodia haselbergii) is a low-growing indoor cactus whose white silky spines can hide mealybugs until infestations are well established. Spider mites appear in heated dry rooms, and scale insects colonise the ribs. Root mealybugs are a secondary risk. Monthly inspection is the best defence.
