Why does your Hippeastrum Amigo have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely the adult stage of fungus gnats, which lay eggs in the top layer of organic matter. Their larvae feed on the fine feeder roots of your Hippeastrum, which can lead to weakened bulb development.
Hippeastrum bulbs are highly susceptible to rot if kept in overly damp conditions. Excessively moist soil provides the ideal breeding ground for fungus gnat larvae and promotes fungal pathogens.
The presence of decaying peat moss or old compost in the Hippeastrum potting mix provides nutrients for flying insects. As organic matter breaks down, it creates a moist environment that attracts pests.
