Fungus Gnats

The tiny black flies are likely the adult stage of fungus gnats, which thrive in the moist, organic-rich soil typical for Gerbera Daisies. Their larvae feed on decaying organic matter and can damage the delicate feeder roots of the Gerbera.

Very Common

How to confirm: Place a yellow sticky trap near the base of the plant to confirm the presence of flying adults.

Soil Moisture Imbalance (Overwatering)

While not a direct cause of flies, constant high moisture in the Gerbera's potting medium attracts fungus gnats and creates an environment for fungal pathogens. This can lead to crown rot, which is fatal to Gerbera Daisy species.

Very Common

How to confirm: Stick your finger two inches into the soil; if it feels saturated or muddy, you are overwatering.

Fruit Flies (Drosophila)

If there is fermenting organic matter or overripe compost in the pot, fruit flies may be attracted to the Gerbera's growing area. Unlike fungus gnats, these are attracted to sugars rather than soil moisture.

Common

How to confirm: Check if the flies hover specifically around decaying plant debris or nearby ripening fruit instead of the soil surface.

1 Inspect the soil and surrounding area for overripe organic matter, rotting fruit, or fermenting compost that may be attracting the flies.

2 Remove any decaying organic material from the pot and clean the surface of the soil to eliminate the primary food source.

3 Set up a trap near the plant using a natural attractant to capture the adult flies.
