Why does your Maranta leuconeura have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThe tiny black flies are likely fungus gnat larvae or adults, which thrive in the moist, organic-rich soil preferred by Maranta. Their larvae feed on decaying organic matter and can occasionally damage fine surface roots of the Prayer Plant.
Maranta leuconeura requires consistent moisture but is highly susceptible to root rot if soil remains saturated. Wet, stagnant soil provides the ideal breeding ground for fungus gnat populations.
Potting mixes high in peat moss or compost provide an abundant food source for the life cycle of small flies. While Maranta loves humidity, too much decomposing organic material attracts pests.
