Fungus Gnats

These small flies breed in the moist organic matter of the potting medium. Their larvae feed on the fine root hairs of your Hippeastrum, which can weaken the bulb's ability to support large flower stalks.

Hippeastrum Samba bulbs are highly susceptible to rot if the medium remains saturated. Constant moisture attracts fungus gnats and provides the ideal breeding ground for their larvae.

Very Common
