Sciarid Flies

Similar to fungus gnats, these flies are attracted to high humidity and damp soil common in miniature rose containers. They can cause secondary damage if their larvae begin feeding on the delicate root systems of the small plant.

Sapstilla (Fruit Flies)

If there is overripe organic matter or fermenting nectar on the rose petals, fruit flies may be attracted to the plant. They do not live in the soil but are drawn to the sweet scent of the 'Amorina' blooms.

Common

1 Remove and dispose of any overripe, fermenting, or decaying rose petals from the plant to eliminate the primary attractant for fruit flies.

2 Clean the area around the plant to ensure no organic debris or sugary nectar residue remains on the leaves or surrounding surfaces.
