Why does your Anthurium andraeanum Turenza have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely the adult stage of fungus gnats, which thrive in the moist organic matter of Anthurium soil. Their larvae feed on decaying roots and can weaken the plant by causing small lesions that lead to secondary infections.
Anthuriums require well-draining media; constant saturation creates the perfect breeding ground for gnats and promotes anaerobic conditions. This moisture-heavy environment attracts flies looking for damp organic substrate to lay eggs.
Old, dead leaves or decomposing peat moss in the Anthurium pot provide nutrient-rich food for fly larvae. As organic matter breaks down into finer particles, it becomes an ideal habitat for insect colonization.
