What Are Fungus Gnats?

How To Get Rid Of Gnats In Plants | 7 Easy Ways To Get Rid Of Fungus Gnats Naturally

Fungus gnats, scientifically known as Bradysia spp., are small, flying insects that are commonly found in and around indoor plants. These annoying bugs have long legs and thin wings, and they are typically gray or black.

These small 1/8-inch-long bugs are attracted to decomposing leaves on the soil surface next to your plants and moist potting soil. The larvae that develop from their eggs in the soil consume organic matter and the hairs on plant roots.

While adult gnats don’t usually cause harm, their larvae can cause decaying and diminished development when they damage roots.


Signs Of Fungus Gnats In Plants

Here are some common signs that indicate you may have fungus gnats in your plants:

  • Tiny Flying Insects: Seeing little, dark-colored flies surrounding your plants is one of the most clear signs. Due to their poor flying capacity, fungus gnats usually remain near the surface of plants or the soil.
  • Yellowing Leaves: Damaged roots can cause leaves to turn yellow.
  • Larvae in Soil: If you carefully inspect the soil around the base of your plants, you may spot these larvae.
  • Visible Damage to Roots: Fungus gnat larvae feeding on roots can slow plant growth.
  • Fungal Growth on Soil Surface: You might observe a coating of mold or fungus forming on the soil’s surface because fungus gnats feed organic matter and fungi found in the soil.
  • Limp Appearance: The plant could seem dull or stiff.
  • Moist Soil Conditions: Fungus gnats prefer moist conditions, particularly if you’ve been overwatering or have little drainage.

1. Allow The Soil To Dry Out

Gnats love wet soil. To prevent them from settling among your plants, allow the top layer of soil to become completely dry in between waterings. Be sure not to let your plants wilt, but adjust your watering schedule to maintain moderate soil moisture

2. Use Yellow Sticky Traps

These traps attract and catch adult gnats. Set these traps close to your plants, especially in nearby of any locations where you’ve noticed gnat activity. Gnats attract yellow surfaces and become trapped there due to the sticky nature of the material.

3. Apply Neem Oil

A natural repellent that can help in the control of fungus gnats is neem oil. Neem oil is effective against gnats, their eggs, and larvae. Mix it with water and spray it on the soil surface.

4. Try a Vinegar Trap

Create a trap by placing apple cider vinegar in a container with a few drops of dish soap. The gnats will be attracted to the vinegar and get trapped.

5. Use Cinnamon Powder

Entire fungus gnats can be repelled by sprinkling cinnamon powder on the soil’s surface. Because of its antifungal qualities, cinnamon can make gnats and their larvae unpleasant.; it can deter gnats and disrupt their lifecycle.

6. Try Hydrogen Peroxide

Dilute hydrogen peroxide with water (1:4 ratio) and water your plants with it. It helps kill larvae and aerates the soil.

7. Beneficial Nematodes

Tiny worms called beneficial nematodes feed on the larvae of fungus gnats in the soil. Pets and plants can safely use them, but for best results, use them as directed on the packaging.

8. Remove Infested Soil

If you have reason to suspect that the soil has become heavily gnat-infested, you might want to carefully remove the top inch or so of soil and replace it with a clean, fresh potting mix. By doing so, you may be able to stop additional infestation and lower the number of larvae.

  • Ensure Proper Drainage: Ensure that your pots have adequate drainage holes at the bottom.
  • Cleanliness and Maintenance: Keep your plants and their surroundings clean. Remove fallen leaves, dead plant material, and debris from the soil surface regularly.

  • Air Circulation: Make sure there is enough airflow around your plants. This makes the soil dry out faster after watering and makes the environment more resistant to the growth of fungus gnats.
  • Regular Monitoring: Regularly check your plants for signs of pests like gnats. Early detection enables you to take care of an infestation before it gets out of control.
