Clamshell Orchid pests — FAQ
What is eating my clamshell orchid?
Clamshell Orchid (Epidendrum cochleatum) is susceptible to mealybugs and spider mites indoors, where dry air encourages rapid mite build-up and mealybugs exploit the pseudobulb and leaf-sheath crevices. Scale insects and aphids on flower spikes are also occasional problems. Good airflow, quarantine of new plants, and monthly inspection keep this long-blooming orchid healthy.
