Mealybugs on snake plant — Fix & Prevention

What's Happening

Root mealybugs (Pseudococcidae) infest the root zone of snake plants, hidden from view until populations explode. Unlike foliar mealybugs, these soil-dwellers thrive in the succulent root environment, feeding on root tissue and creating cottony masses around rhizomes. They emerge from drainage holes or soil surface when watering. The waxy coating protects them from topical treatments, requiring systemic intervention.

How to Fix It

1
Unpot snake plant and inspect roots for white cottony masses; isolate immediately to prevent spread
2
Prune heavily infested roots with sterilized scissors; rinse remaining roots thoroughly
3
Apply systemic insecticide (imidacloprid) via soil drench following label rates for ornamentals
4
Soak roots in dilute hydrogen peroxide solution (1:10 ratio) for 1 hour to sterilize
5
Repot in fresh sterile fast-draining succulent mix; use fresh pot to eliminate hidden pests
6
Monitor weekly for 3 months; if reinfestation occurs after 1 month, discard plant to protect collection
