Why does your Hippeastrum Moonlight have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely fungus gnats, whose larvae thrive in the moist organic matter of the Hippeastrum potting mix. They feed on decaying plant material and can damage the delicate developing root system of your Amaryllis.
Frequent watering or poor drainage creates the damp, anaerobic environment that attracts fungus gnats. For Hippeastrum Moonlight, excess moisture can lead to bulb rot alongside the fly infestation.
A potting medium that is too rich in compost or peat moss provides an ideal breeding ground for fly larvae. While Amaryllis love nutrients, too much decomposing organic matter attracts pests.
