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.
