Eureka Lemon pests — FAQ
What is eating my eureka lemon?
Eureka Lemon is most threatened by citrus leafminer, which tunnels silvery trails into young leaves. Outdoor trees also face aphids, scale insects, and citrus whitefly. In warmer US regions, Asian citrus psyllid is a serious concern. Good airflow, horticultural oil sprays, and monitoring new growth keep most pests manageable.
