Fungus gnats are common indoor pests. Adult gnats are about â long, grayish to black in color, with long legs, antennae and one pair of wings. The adults do little plant damage, but can be unpleasant if they are present indoors in large numbers. The larvae live in the soil and chew on plant roots.
It is the larvae of the fungus gnats that do the most damage. The adults live about a week, but during that time they lay hundreds of eggs in the soil of your potted plants. They are particularly attracted to damp soil that is rich in organic matter.f you see fungus gnats flying around your plants, you can be sure that there are also larvae feeding on the roots of your plants. To monitor the fungus gnat population, use yellow sticky traps placed horizontally near the plants. Yellow sticky traps are available at many garden centers.
