Why does your Cyclamen neapolitanum have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The presence of tiny black flies in Cyclamen is most often caused by fungus gnats, whose larvae thrive in the moist organic matter of the potting soil. They are attracted to the high humidity levels required by Cyclamen neapolitanum.
Cyclamen neapolitanum is highly susceptible to tuber rot if the growing medium remains saturated. Constant moisture creates the perfect breeding ground for fungus gnat larvae and other soil-dwelling pests.
If there is fermenting organic matter in the pot or nearby decaying plant debris, fruit flies may be attracted to the area. While less common than fungus gnats for this species, they can appear if the soil surface has a film of decomposing material.
