Why does your Anthurium andraeanum Elido have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely fungus gnat larvae or adults, which thrive in the moist, organic-rich potting media typically used for Anthuriums. They feed on decaying organic matter and can damage the delicate root systems of your Elido cultivar if populations become high.
Frequent moisture in the substrate creates an ideal breeding ground for fungus gnat eggs. For Anthuriums, which require well-draining, aerated media, excess water leads to anaerobic conditions that attract these pests.
If your potting mix contains high amounts of peat moss or compost that has begun to decompose, it provides a nutrient-rich environment for fly larvae. This is common in Anthurium mixes intended to retain humidity.
