Why does your Kalanchoe pumila have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The presence of tiny black flies in succulent media like Kalanchoe pumila almost always indicates fungus gnat larvae living in the top layer of soil. These flies are attracted to the moisture and decaying organic matter required for their life cycle.
Kalanchoe pumila is a succulent that requires well-draining soil; frequent watering creates the damp environment necessary for fungus gnat eggs to hatch and thrive. High humidity around the soil surface also attracts adult flies.
If the potting mix contains high amounts of peat moss or compost that has begun to decompose, it provides an ideal food source for fly larvae. This organic breakdown creates a nutrient-rich environment for pests to colonize.
