Fungus Gnats

The larvae of these flies live in the top layer of moist organic matter and feed on decaying roots. For a succulent like Kalanchoe tomentosa, frequent watering creates the perfect humid environment for their life cycle.

Overwatering leading to Root Rot

While not the fly itself, excessive moisture attracts gnats and causes the fleshy roots of the Pussy Ears to decay. This decay provides a secondary food source for larvae and weakens the plant's structural integrity.

Very Common

How to confirm: Gently lift the plant from its pot to check if the roots are mushy or dark brown instead of firm and white.

Saprophagous Fruit Flies

If there is organic debris or fermenting nectar/sap on the leaves, small fruit flies may be attracted to the plant. This is less common than fungus gnats but can occur if the Kalanchoe is kept in a high-humidity environment with rotting organic matter nearby.

Common

How to confirm: Inspect the base of the plant and the soil surface for any signs of decomposing organic material or fermenting juices.

1 Clean the plant leaves and surrounding area to remove any fermenting sap, nectar, or decaying organic matter that attracts fruit flies.
2 Reduce humidity around the Kalanchoe and ensure the soil surface is dry to discourage breeding environments.
3 Deploy yellow sticky traps near the plant to capture and monitor the adult fly population.
