Common Pests Eating Cabbage Leaves
Cabbage Worms
Cabbage worms are the larvae of the cabbage white butterfly. They are green and can blend in with the leaves, making them hard to spot. They chew large, irregular holes in the leaves.
Aphids
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.
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.
Cutworms
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.
Cabbage Loopers
Cabbage loopers are green caterpillars that move in a looping motion. They feed on the undersides of the leaves, creating ragged holes.
Slugs and Snails
Slugs and snails feed on cabbage leaves, leaving large, irregular holes and silvery trails on the leaves.
Signs of Infestation
Chewed Leaves
Look for irregular holes and ragged edges on the leaves. This type of damage is often caused by caterpillars like cabbage worms and cabbage loopers.
Yellowing and Curling
If the leaves are yellowing, curling, or wilting, it might be due to aphid infestation. Aphids 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.
Silvery Trails
Slugs and snails leave behind silvery trails on the leaves and soil, along with large, irregular holes.
Control Methods
Handpicking
For larger pests like cabbage worms, cabbage loopers, and slugs, 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. 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 cabbage 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, slugs, 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, cabbage worms, and flea beetles. Mix according to the instructions and spray on affected plants.
Natural Remedies
Companion Planting
Planting herbs and flowers like marigolds, dill, and nasturtiums can help repel pests. These plants can attract beneficial insects that prey on common cabbage 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.
