Why does your Anthurium andraeanum Nevada have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The most likely cause is the larvae of fungus gnats feeding on organic matter and fungi in the soil. The adult flies emerge to lay eggs in moist potting media, often triggered by high humidity or frequent watering required by Anthuriums.
Anthurium Nevada requires well-draining substrate; constant moisture promotes fungal growth which attracts gnats. This environment also leads to root hypoxia, making the plant more susceptible to pests.
If using a heavy peat-based mix, decomposing organic material provides a perfect breeding ground for flies. As the medium breaks down, it creates a nutrient-rich environment for larvae.
