Fungus Gnats

The most common cause of tiny black flies in succulents is fungus gnats, whose larvae thrive in the moist organic matter of the potting mix. While they don't eat the Echeveria directly, their presence indicates that the soil remains damp for too long, which can lead to root rot.

Overwatering and High Soil Moisture

Echeveria agavoides requires well-draining, gritty soil and periods of complete dryness. Constant moisture creates the perfect breeding ground for insect larvae and can lead to the soft, translucent leaves characteristic of rot.

Saprophytic Fly Larvae (Decomposing Organic Matter)

If the potting medium contains too much peat moss or compost, flies may be attracted to the decaying organic material. This provides a nutrient-rich environment for fly life cycles to complete within the pot.

How to confirm: Examine the surface of the soil for any visible movement or tiny white larvae near the base of the plant.
