Fungus gnats: signs & treatments

Signs

  • Small, black gnats flying slowly and resting on wet soil
  • Look similar to fruit flies

Treatments

  • Help soil dry out completely by reducing watering frequency and increasing airflow and sunlight
  • Make a gnat trap: pour a couple splashes of apple cider vinegar and a few drops of dish soap into a cup, cover with plastic wrap, then poke a finger-sized hole in the plastic; keep near plant
  • Repot with gritty, well-draining soil
  • Top soil with diatomaceous earth
