Common Pests Eating Broccoli Leaves

Cabbage Worms

Cabbage worms are the larvae of several species of butterflies and moths, including the cabbage white butterfly and the diamondback moth. They are green and can blend in with the leaves, making them hard to spot.

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 and yellow.

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.

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.

Control Methods

Handpicking

For larger pests like cabbage worms, cabbage loopers, 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. 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 broccoli 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, 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 broccoli 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.
