Why does your Anthurium andraeanum Sharade White have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The presence of tiny black flies is most commonly due to fungus gnats, whose larvae live in the organic matter of moist potting soil. They thrive in the high-humidity environments required by Anthurium andraeanum and feed on decaying roots and fungi.
Frequent watering or poorly draining media creates the perfect breeding ground for gnats. In Anthuriums, this often leads to a cycle where wet soil attracts flies, which then introduces pathogens that cause root rot.
If the potting mix contains large amounts of peat moss or decomposing bark, it provides a nutrient-rich environment for fly larvae. As this organic matter breaks down, it releases gases and nutrients that attract adult flies.
