Fungus Gnats (Sciaridae)

The larvae of these flies thrive in the moist, organic-rich soil preferred by Cyclamen hederifolium. They feed on decaying plant matter and can damage delicate tuberous roots if populations become high.

Soil Moisture Excess / Overwatering

Cyclamen hederifolium require well-draining substrate; constant wetness attracts fungus gnats and promotes fungal growth. Excessive moisture can also lead to tuber rot, which creates the organic decay these flies feed upon.

Very Common

How to confirm: Insert your finger 2cm into the soil to check if it remains soggy long after watering.
