fungus gnats on Alocasia Frydek
Quick answer
If your Alocasia Frydek has fungus gnats, the most likely cause is: Fungus gnat adults are 3-4 mm flies that hover above damp substrate, where they lay eggs that hatch into maggots living in the top layer of the soil; the larvae feed on fungus and decaying organic matter in the substrate rather than on the established Alocasia Frydek, but they can chew tender root tips and fresh root hairs when their numbers climb, and rich organic mixes with high fungal loads make infestations worse.
Start here:
- 1. Allow the top of the Alocasia Frydek substrate to dry out between waterings so the upper layer that adult fungus gnats use to lay eggs stops being a suitable breeding site; surface dryness by itself often collapses a small population.
- 2. Cut back on heavy applications of organic fertilizer and switch to a chunky, well-draining aroid mix with less fungal fuel, since the higher the organic content in the substrate, the more likely you are to attract fungus gnats.

Keep fungus gnats off this Alocasia Frydek
Use a free-draining chunky aroid substrate that lets the top surface dry between waterings, avoid waterlogged pockets, and rely on good all-around care and maintenance to prevent fungus gnat numbers from escalating in the first place.
