Fungus Gnats

Identification: Small, dark flies hovering near soil.

Symptoms: Larvae feed on roots, causing slow growth and weak plants.

Control:

  • BTI (Bacillus thuringiensis israelensis): Apply to soil to kill larvae (e.g., Mosquito Dunks).

  • Sticky Traps: Place yellow sticky traps near soil.

  • Beneficial Nematodes: Release Steinernema feltiae to target larvae.

  • Companion Plants: Use rosemary or thyme to repel fungus gnats.

  • Avoid Overwatering: Keep soil dry between waterings.
