Common Pests Eating Eggplant Leaves

Flea Beetles

Flea beetles are tiny, black or brown beetles that hop like fleas. They chew small holes in the leaves, giving them a “shot-hole” appearance.


Aphids are small, soft-bodied insects that can be green, black, or gray. They feed on the sap of the plant, causing the leaves to curl, yellow, and become distorted.

Spider Mites

Spider mites are tiny, red or brown mites that suck the sap from the leaves, causing them to develop yellow spots and eventually turn brown and dry out.

Colorado Potato Beetles

Colorado potato beetles are yellow and black striped beetles that can cause significant damage to eggplants by feeding on the leaves.


Cutworms are the larvae of certain moths. They are usually brown or gray and can be found at the base of the plant, where they chew through the stems and leaves.


Hornworms are large green caterpillars that can quickly defoliate an eggplant. They have a horn-like projection on their rear end.

Signs of Infestation

Chewed Leaves

Look for small holes and ragged edges on the leaves. This type of damage is often caused by beetles and caterpillars.

Yellowing and Curling

If the leaves are yellowing, curling, or wilting, it might be due to aphid or spider mite infestation. These pests can also leave a sticky residue known as honeydew.

Small Holes

Tiny, round holes scattered across the leaves are a sign of flea beetle damage. These beetles can cause significant damage, especially to young plants.

Cut Stems

Cutworms chew through the stems at the base of the plant, causing the plant to collapse. Look for severed stems and check the soil around the base for cutworms.

Large, Irregular Holes

Large, irregular holes are often caused by hornworms or Colorado potato beetles. These pests can quickly defoliate a plant if not controlled.

Control Methods


For larger pests like hornworms, Colorado potato beetles, and cutworms, handpicking is an effective control method. Inspect your plants regularly and remove any pests you find.

Insecticidal Soap

Insecticidal soap is effective against soft-bodied insects like aphids and spider mites. Spray the soap directly on the affected areas, making sure to cover the undersides of the leaves.

Row Covers

Using row covers can protect your eggplant plants from a variety of pests. These covers create a physical barrier that prevents pests from reaching the plants while allowing sunlight and water to pass through.

Diatomaceous Earth

Sprinkle diatomaceous earth around the base of your plants to deter crawling insects like cutworms and flea beetles. This natural powder dehydrates and kills insects on contact.

Neem Oil

Neem oil is a natural insecticide that works against a wide range of pests, including aphids, spider mites, and flea beetles. Mix according to the instructions and spray on affected plants.

Natural Remedies

Companion Planting

Planting herbs and flowers like marigolds, basil, and dill can help repel pests. These plants can attract beneficial insects that prey on common eggplant pests.

Beneficial Insects

Introducing beneficial insects such as ladybugs, lacewings, and parasitic wasps can help control pest populations. These insects feed on aphids, caterpillars, and other pests.

Homemade Sprays

  • Garlic Spray: Blend garlic cloves with water and a small amount of dish soap. Spray this mixture on your plants to repel pests.
  • Pepper Spray: Mix hot pepper flakes with water and a few drops of dish soap. Spray this solution on the leaves to deter pests.
