If you have recently noticed tiny bugs crawling around your dish garden plants, you’re not alone. These little bugs are known as “soil gnats” or “fungus gnats” and can be a common problem for indoor gardeners.

What Are Soil Gnats?

Soil gnats are small, dark-colored flies that lay their eggs in the soil of houseplants. The larvae feed on organic matter in the soil, which can cause damage to the roots of your plants. Adult soil gnats are harmless to your plants, but their presence can be a nuisance.

Why Do I Have Soil Gnats?

Soil gnats thrive in moist environments, so overwatering your plants can create the perfect breeding ground for them. Plant debris and dead leaves left in the soil can also attract soil gnats. They can also hitch a ride on new plants or potting soil.

How Can I Get Rid of Soil Gnats?

  1. Allow the soil to dry out between waterings. Soil gnats cannot survive in dry soil.
  2. Remove any dead leaves or plant debris from the soil.
  3. Add a layer of sand or gravel to the top of the soil to prevent adult soil gnats from laying their eggs.
  4. Use sticky traps to catch adult soil gnats.
  5. Apply a biological control agent such as nematodes or Bacillus thuringiensis israelensis (BTi) to the soil to kill larvae.

Can Soil Gnats Harm Humans?

Soil gnats do not bite or sting humans and are not known to transmit diseases.
