fungus gnats on Monstera Deliciosa
Quick answer
If your Monstera Deliciosa has fungus gnats, the most likely cause is: Fungus gnats (Bradysia spp.) are attracted to the moist, organic-rich soil often used for Monsteras. While adults are a nuisance, the larvae feed on delicate root hairs, potentially opening paths for secondary fungal infections like Pythium.
Start here:
- 1. Apply Mosquito Bits or dunks (containing Bacillus thuringiensis israelensis - BTI) to the soil surface or via "BTI tea" (soaking bits in water before use).
- 2. Allow the top 2-3 inches of soil to dry completely between waterings to kill surface-dwelling larvae.
