Beaucarnea Stricta pests — FAQ
What is eating my beaucarnea stricta?
Beaucarnea stricta, the Mexican ponytail palm relative, stores water in its swollen caudex and rarely draws heavy pest pressure. Spider mites and mealybugs are the most frequent indoor attackers, typically triggered by dry air or overwatering. Scale insects occasionally appear on the trunk. Root rot from overwatering is a bigger risk than most pests.
