To know how to get rid of cabbage aphids, you must first understand their life cycle and the damage they cause.

I’ll go over the life cycle of cabbage aphids, their damage, and how to get rid of them in this article.

Cabbage Aphids

Aphids are tiny, pear-shaped insects that reside in plant colonies. They feed on plant juices, causing them to wither and die.

Aphids come in various colors, including green, yellow, brown, and black. Cabbage aphids can be found on cabbage, broccoli, cauliflower, and Brussels sprouts, as well as other cabbage-related plants.

They have been known to attack plants from the same family when they are in close proximity.

When you first see these pests, they can be readily fooled with other insects with similar appearances that do not harm plants.

If you examine their body form closely, you will see a tiny waist (petiole). Two tubes, or cornicles, protrude from the back of their abdomen, poking out from beneath their wings.

Cabbage Aphid Damage Symptoms

Young leaflets and vulnerable stems develop twisted as a result of the incident of black-green, greenish-yellow, and pinkish soldier aphids (Family Aphididae) on cauliflower. individually or in whorls (Brassicaceae).

Aphids eat young plant tissues, limiting growth, curling, and deformation of leaves, and malformed (galled) blooms are symptoms of cabbage aphid damage. Plants may die in extreme conditions. 

Soldier aphids (1/16 to 1/8 inch long) have a black body with green stripes on the sides and are wingless. The tiny individual is generally seen together.

On the underside of new blades, The unwinged female aphid is a substantial brown aphid with green stripes (usually forming galls on cabbage plants).

Various Treatments

  • Remove aphids from the plants 
  • Apply a soap solution to insects
  • Apply a systemic insecticide.

Also, some plants have natural predators that devour aphids, such as ladybugs.

If the pests are too numerous, complement the natural predators with predatory insects such as lacewings, parasitic wasps, and predatory beetles.

If you don’t want to use pesticides, handpick aphids as they hatch and kill them with a soap solution [at night is preferable] or spray them with a registered pesticide authorized for organic farming when it rains.

Natural Way To Acquire Rid Of Cabbage Aphids

Natural Way To Acquire Rid Of Cabbage Aphids

Insecticides, natural enemies, and cultural measures such as not overfertilizing with nitrogen fertilizer are options for managing cabbage aphids. Insecticides are divided into two types: contact and systemic.

Non-systemic insecticides, often known as contact insecticides, kill aphids when they come into contact with them.

Aphids are killed with systemic insecticides that penetrate their bodies and attack their target organ or structure (e.g., larvae).

When systemic insecticides are absorbed into the plant’s leaves and stems, they are most efficient at killing aphids. Contact pesticides should be used in modest amounts rather than in massive sprays for dealing with cabbage aphids.

There is an option available to utilize hazardous chemicals or any type of spray to get rid of cabbage aphids. This is accomplished by using helpful microscopic algae.

Identifying the type of aphids present is the first step in any natural management method. Identification is critical because the effectiveness of management methods varies depending on the kind of aphids you’re dealing with.

Identifying the plant from whence the aphids are coming, microscopic analysis, and looking at photos or other records from the previous year are all identification methods.


Time is the final word on how to get rid of cabbage aphids. Unless you make an effort to eradicate them, their population will rise.
