Hall's Living Stones pests — FAQ
What is eating my hall's living stones?
Hall's Living Stones (Lithops hallii) can fall prey to mealybugs sheltering in the central fissure and to root mealybugs below the soil. Fungus gnats are an occasional nuisance if the growing medium holds moisture. Because Lithops are extremely drought-adapted, any excess watering stresses the plant and greatly increases pest susceptibility.
