Updated: June 7, 2022

Eggplants are a popular vegetable among gardeners, but they can also attract gnats. Gnats are small, flying insects that can be a nuisance for gardeners. They can also cause damage to eggplant plants by feeding on the leaves and stems, and laying eggs in the soil. Fortunately, there are several ways to get rid of gnats in your eggplant plant.

Identify the Type of Gnat

Before you start treating the gnats, it is important to identify the type of gnat you are dealing with. There are several types of gnats that can infest eggplant plants, including fungus gnats, fruit flies, and root maggots.

  • Fruit Flies: These gnats are attracted to ripe fruit and vegetables. They are small and brown in color with red eyes.

  • Root Maggots: These gnats lay their eggs in the soil near the roots of plants. The larvae then feed on the roots, causing damage to the plant. They are white in color and about ¼ inch long.
