The Cabbage Looper can create a mess in no time. It eats your cabbage leaving behind leaves with holes all in them. Click through NOW to learn how to get rid of them...

When a Cabbage Looper rears its ugly head in your garden it can be devastating to your cabbage plants. They eat it up fast if you don’t catch it in time and make them look terrible!

I have had them a few times and when I go outside to look at my beautiful cabbage I see leaves that look more like lace than cabbage… :/ It’s truly disappointing and reminiscent of Tomato Hornworm damage, only the cabbage have actual holes – here, there, and everywhere truly making it look like lace.

But, let’s start at the beginning and find out what they are and how to deal with them.

The Cabbage Looper looks nothing like this… 🙂

Cabbages are cold-hardy annuals or biennial vegetables that are generally easy to grow. However, they can be susceptible to certain pests that feed on their lush leaves.

Today, we’ll be talking about the cabbage looper and how you can prevent them in your cabbage patch. Let’s get started!

What Is A Cabbage Looper?

A cabbage looper can feed on cabbage, kale, broccoli, and other cole crops.

The Cabbage Looper is a kind of moth that is widely distributed throughout North America. Its larvae is a common and destructive pest often found in cole crops or brassicas like cabbages, kale, collards, kohlrabi, broccoli, Brussels sprouts, and cauliflower.

They are called loopers because of the way they move through the leaves they feed on. These pale green caterpillars don’t have legs in the middle of their bodies which causes them to loop and double up as they inch along the leaves of your crops.

They can eat up to three times their body weight in plant material and can grow up to 1 ½ inch long. They’re most destructive during the last few days of their development since this is when they munch on the leaves of your crops the most.

They’re considered one of the most problematic cabbage pests. This is because they eat large areas on the underside of leaves. They also tend to eat baby cabbage plants. Plus, they can leave behind a sticky frass that can contaminate your plants.

Adult cabbage looper moths don’t do as much damage since they feed on nectar instead of plant material.

What Plants Do Cabbage Loopers Affect?

Cabbage loopers eat tomatoes, lettuce, spinach, celery, parsley, beets, peas, and potatoes.

Cabbage loopers generally prefer cruciferous vegetables like cabbages and broccoli. They grow on these plants faster because of their nutritional content.

They are also attracted to a wide range of plant odors and floral compounds including:

  • phenylacetaldehyde
  • methyl salicylate
  • 2-phenyl ethanol
  • benzaldehyde
  • benzyl alcohol
  • benzyl acetate
  • methyl-2-methoxy benzoate

However, almost 160 different crops can also serve as host to these pests including lettuce, spinach, celery, parsley, beets, peas, potatoes, and tomatoes. Other hosts include alfalfa, soybeans, and cotton.

Young cabbage looper larvae feed on the undersides of leaves and create windowpane patterns especially in thick-leaved crops.

As they mature, the larvae can chew ragged holes in the center of the leaves and may even bore into cabbage and broccoli heads. This can result in whole leaf loss and major damage to your crops.

Once you spot a cabbage looper, remove them immediately.

The simplest and safest way to get rid of cabbage loopers in your cabbage patch is by manually removing them – just pick them off.

You can easily spot them and pick them off one by one. The best time to do this is in the morning and late in the evening. Be sure to dispose of them properly so they won’t have a chance to mature.

Be sure to also check for eggs, check the underside of plant leaves and scrape them off gently. This allows you to prevent a new generation of cabbage loopers from feasting on your precious cabbage plants.

You can also use spray treatments containing Bacillus thurigiensis or BT, a naturally-occurring soil bacterium and biological pesticide. It’s an organic and slow-acting option that you apply weekly to be effective.

Broad-spectrum insecticides can also be used to get rid of cabbage loopers. However, you need to use it sparingly so you don’t unintentionally kill beneficial insects and pollinators.

If you’ve experienced an infestation during the growing season, be sure to till the plot in the fall and to remove any garden debris to prevent pupae from overwintering because that can cause trouble in the next season.
