Why does your Anthurium andraeanum Aramon 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, which breed in the moist organic matter of the Anthurium's potting mix. Their larvae feed on decomposing organic material and can damage delicate root hairs, potentially leading to root rot in this sensitive species.
Anthuriums require well-draining media; if the substrate remains saturated, it creates the perfect breeding ground for fungus gnat larvae. Constant moisture also stresses the plant's aerobic respiration, making it more susceptible to secondary pathogens.
The presence of highly decomposed peat or bark in the potting mix provides a nutrient-rich food source for fly larvae. As organic components break down, they release gases and attract moisture-loving insects.
