Fungus Gnats (Sciarid Fly)

The presence of tiny black flies in high-moisture plants like Peperomia pellucida is most commonly due to fungus gnats. Their larvae live in the top layers of organic matter and feed on decaying roots and fungal mycelium, thriving in the perpetually damp soil this species requires.

Very Common

Soil Moisture Imbalance (Root Rot precursor)

While Peperomia pellucida loves humidity, overly saturated soil creates the perfect breeding ground for dipteran insects. The decaying organic matter in the pot acts as a food source and egg-laying site for flies.

Common

How to confirm: Stick your finger two inches into the soil to check if it is staying anaerobic or swampy.
