Why does your Amaryllis Ferrari 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 soil typically used for Amaryllis. They feed on decaying organic matter and can damage the delicate developing roots of the bulb if the infestation is severe.
Amaryllis bulbs are highly susceptible to rot if the substrate remains too wet for extended periods. Excessive moisture creates the perfect breeding ground for fungus gnat larvae and can lead to fungal pathogens attacking the bulb.
The presence of uncomposted peat moss or old, decaying mulch in the Amaryllis pot provides a food source for fly larvae. As this material breaks down, it attracts pests that seek out nutrient-rich environments.
