Fungus gnats prefer to lay their eggs in moist soil. Whilst the midges are only perceived as a nuisance, the larvae can also cause damage to plants if they nibble at the roots.

Firstly, you should make sure that they are actually fungus gnats. The small, dark flies are often found near the soil surface of your potted plants. Their larvae, which live in the soil, feed on organic matter and sometimes, unfortunately, on the roots of young plants. If you actually have fungus gnats in your plants, you need to take action.

Fighting fungus gnats

Water once with fermented garlic and chilli extract (2 capfuls to 1 litre of water) and then allow the soil to dry. The natural agent has a deterrent effect on mosquitoes. It is also advisable to only water the plants from below in the saucer, as fungus gnats prefer moist conditions.

Further tips against fungus gnats

  • Sprinkle the soil surface with 1 cm of sand.
  • You can also trap gnats and curb further proliferation by using yellow traps.
  • Even after successful control of fungus gnats, it is important to check the plants regularly and maintain the preventative measures mentioned above to prevent recurrence.
