Fungus Gnats (Sciaridae)

The larvae of these flies live in the top layer of substrate, feeding on organic matter and fine root hairs of the Aloe ferox. Adult flies emerge to lay eggs in moist soil, often triggered by overly frequent watering schedules.

Very Common

Fruit Flies (Drosophilidae)

These flies are attracted to the fermenting sugars found in decaying organic matter or overripe sap if the Aloe ferox has an open wound. They do not live in the soil but hover around the plant looking for moisture and food.

Common

Root Rot secondary infestation

While not the primary cause of flies, underlying root rot in Aloe ferox creates a moist, decaying environment perfect for breeding pests. The black flies are often an indicator that the substrate is staying wet far too long for this succulent species.

Common

How to confirm: Gently lift the plant from its pot to inspect if the roots are dark, slimy, or have a foul smell.

1 Immediately remove the plant from its current pot to inspect the roots for mushy, dark, or foul-smelling decay.

2 Prune away all rotten roots using sterilized tools and repot the Aloe in a well-draining, dry succulent mix containing perlite or pumice to prevent further rot.

3 Apply yellow sticky traps to capture the adult black flies and use a moisture meter to ensure the substrate is allowed to dry out completely between waterings.
