root mealy bugs on Echeveria
Quick answer
If your Echeveria has root mealy bugs, the most likely cause is: Root mealy bugs (Rhizoecus spp.) infest succulent root systems by feeding on fine root hairs and tubercles, injecting toxins that disrupt water and nutrient uptake. The plant gradually yellows and declines, often mimicking overwatering symptoms.

- 1. Remove plant from pot and inspect root system — white waxy threads or powdery residues indicate mealy bugs
- 2. Wash roots thoroughly under lukewarm water to remove soil and exposed pests
