Firesticks Plant pests — FAQ
What is eating my firesticks plant?
Firesticks (Euphorbia tirucalli 'Sticks on Fire') has very few natural pest enemies indoors, aided by its toxic latex sap. Mealybugs occasionally colonise stem junctions, and spider mites appear in very dry conditions. Root mealybugs are the stealthiest threat, causing slow decline before any above-ground signs emerge.
