Fungus Gnats on Indoor Hibiscus: Same Fix, Different Plant

Larvae in Soil, Not on Plant

Adults annoy; larvae feed on decaying bark/roots in wet soil. Dry top layer, add gritty topper (coir, sand, DE), or use potato traps. Bti (Knock-Out Gnats) for heavy cases. Red wine traps adults.

Prevention

Sterile, bark-free, perlite-rich mix. Let dry well between waterings.
