Mealybug Infestation

Mealybugs are small, soft-bodied insects that secrete a white, waxy, cotton-like substance to protect themselves. They feed on the sap of Echeveria Rolly, often congregating in the tight crevices between the leaf rosettes.

Very Common

Powdery Mildew

Scale Insects

Some species of scale insects produce white, waxy secretions that can resemble cottony fluff. These pests attach themselves to the fleshy leaves of the Echeveria, slowly draining nutrients and causing stunted growth.

Common

How to confirm: Look for small, hard bumps or shells underneath the white fuzz that do not move when disturbed.
