How to Get Rid of Fungus Gnats Naturally

Noticing tiny black flies buzzing around your houseplants? You’re likely dealing with fungus gnats—a common nuisance for plant lovers. While adult gnats don’t bite or harm humans, their larvae can damage your plant's roots over time.

Thankfully, you don’t need harsh chemicals to fix the problem. Here’s how to eliminate fungus gnats naturally and keep them from coming back.

What Causes Fungus Gnats?

Fungus gnats thrive in:

• Overwatered soil
• Poor drainage
• High humidity
• Organic-rich potting mixes

The larvae live in damp soil and feed on decaying material and roots—especially in plants that stay too wet for too long.

5 Natural Ways to Get Rid of Fungus Gnats

1. Let Soil Dry Out

Allow the top 1–2 inches of soil to dry between waterings. Fungus gnats can’t survive in dry conditions.

2. Use Neem Oil to Kill Larvae

Neem oil is a natural pest deterrent—and it’s a key ingredient in our Plant-Based Leaf Shine. Spray the tops and bottoms of leaves and the soil surface. Neem oil helps:

• Kill larvae
  
• Repel adult gnats
  
• Nourish plant leaves

✨ Bonus: It also leaves a beautiful, healthy shine!

3. Bottom-Water Your Plants

Watering from below keeps the soil surface dry, discouraging gnats from laying eggs.

4. Use Sticky Traps

Place yellow sticky traps near your plants to catch adult gnats and reduce breeding.

5. Repot If Needed

For severe infestations, repot using fresh soil. Rinse the roots to remove any larvae.

Prevent Fungus Gnats for Good

• Avoid overwatering
  
• Ensure proper drainage
  
• Keep leaves clean
  
• Use neem oil regularly as a natural defense
