Are fungus gnats harmful to plants?Updated 3 months ago

Yes, fungus gnats can be harmful to plants, especially if their larvae develop in large numbers. The larvae feed on organic material in the soil, but in a severe infestation, they can also attack the roots of plants.

This can lead to damage to the roots, reducing the plant's ability to absorb nutrients and water. In severe cases, this can cause plants to weaken, turn yellow or even die. It is therefore important to tackle a fungus gnats infestation in time.
