Fungus Gnats

The larvae of these flies thrive in the moist, organic-rich substrate required by Kalanchoe. They feed on decaying organic matter and can occasionally damage the delicate root hairs of the paddle plant.

Very Common

How to confirm: Place a yellow sticky trap near the soil surface to see if small black flies are attracted to it.

1 Deploy yellow sticky traps to capture the adult flying gnats and break the breeding cycle.
2 Allow the top inch of soil to dry out completely between waterings to make the environment less hospitable for larvae.
3 Apply a biological control or organic insecticide to target the larvae in the soil.

Overwatering / Root Rot Environment

Kalanchoe thyrsiflora is a succulent that requires well-draining soil; constant moisture creates the perfect breeding ground for fungus gnats and can lead to fungal pathogens in the plant.

Very Common

How to confirm: Check if the soil remains damp for more than a week and inspect the base of the paddles for any softening or discoloration.

1 Reduce watering frequency and allow the soil to dry out completely between waterings to eliminate the moist breeding ground for fungus gnats.
2 Apply yellow sticky traps near the soil surface to capture adult flies and disrupt their reproductive cycle.
3 Repot the plant in a highly well-draining succulent mix, incorporating perlite to improve aeration and prevent future root rot.

Sciarid Flies (Darkwing Flies)

Similar to fungus gnats, these flies target high-moisture environments. They are often present when the substrate has too much peat moss or decaying mulch which provides nutrients for their larvae.

Common

How to confirm: Observe if the flies are hovering specifically around the soil surface rather than the leaves.

1 Reduce watering frequency and allow the top inch of soil to dry out completely to disrupt the larvae's high-moisture habitat.
2 Deploy yellow sticky traps to capture the adult flies and prevent further breeding cycles.
3 Amend the existing soil with perlite to improve drainage and aeration, reducing the organic decay that attracts these flies.
