Why does your Anthurium andraeanum Orange Champion have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely fungus gnat adults, whose larvae live in the upper layers of moist potting media. They thrive in the organic-rich, consistently damp substrate preferred by Anthuriums, feeding on decaying organic matter and fungal mycelium.
Frequent moisture levels required for Orange Anthuriums can lead to a soggy medium that promotes fungal growth. This decay provides the ideal food source and breeding ground for fungus gnat larvae.
A substrate with too much peat moss or decomposing bark can host high populations of decomposers. As these materials break down, they attract flies that lay eggs in the nutrient-rich decay.
