Why does your Anthurium andraeanum Alabama Pink 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 lay eggs in moist organic matter. Their larvae feed on the decaying roots and fungal mycelium present in overwatered Anthurium soil.
Anthuriums require well-draining media; constant moisture provides the perfect breeding ground for fungus gnat larvae and can lead to root rot. This environment encourages the lifecycle of the flies.
The presence of decomposing peat or bark in the potting mix can attract flies and provide food for their larvae. As the media breaks down, it becomes more acidic and holds more moisture, favoring pests.
