Gardeners know that cabbage worms can be a pesky pest in the vegetable patch. These small green larvae, the caterpillar form of white cabbage butterflies, feed on the leaves and stems of cabbage, kale, broccoli, and other brassica crops. While the adult butterflies themselves are beneficial to wild pollinators, their larval stage can cause a lot of damage to your plants.
So, what’s a gardener to do when faced with a cabbage worm problem? Instead of reaching for the spray that may harm other insects and wildlife, there are some tricks you can adopt to naturally control these pests. One simple method is to create a diversion for the cabbage worms. Placing decoy plants, like nasturtiums or mustard greens, nearby can lure them away from your precious crops.
Another strategy is to physically remove the cabbage worms from your plants. It’s a bit time-consuming, but it’s worth it. Inspect your brassicas regularly, and if you find any worms, pick them off and drop them into a bucket of soapy water. This simple method can effectively reduce the cabbage worm population in your garden.
One tried and true technique, often used by our grandmas, is to use floating row covers to protect your plants from cabbage worms. These covers block the butterflies from laying their eggs on your crops, thus preventing the larvae from developing. Just make sure to keep the edges sealed tightly, so the butterflies can’t find their way in.
If your cabbage worms have already snatched a few bites out of your greens, don’t despair. There are organic sprays available that will help control the problem without harming beneficial insects. Check with your local garden center or consult trusted online sources for references and recommendations on how to deal with cabbage worms.
Last but not least, consider attracting natural predators to your garden. Beneficial insects like parasitic wasps, lacewings, and ladybugs can help keep cabbage worm populations in check. You can create a welcoming habitat for these predators by planting flowers rich in nectar and pollen, such as dill, cilantro, or fennel, around your cabbage plants.
By using these strategies and adopting organic pest control methods, you can effectively manage cabbage worms in your garden without resorting to harmful chemicals. Remember, a little extra effort and thinking ahead can go a long way in protecting your beloved brassicas!
Cabbage white caterpillars and holes in your plants
If you’ve noticed small holes in your cabbage or other brassicas, chances are you have cabbage white caterpillars. These tiny green larvae can wreak havoc on your vegetable garden, feeding on the leaves and creating unsightly damage. Unfortunately, although they may look harmless, these caterpillars can quickly demolish an entire plant if left unchecked.
Preventing cabbage white caterpillars from infesting your plants is the best course of action. Here are some tips to help you keep these pests away:
- Identifying the signs: Look for tiny white or yellow eggs on the underside of leaves. These are often laid in groups of 5 or more and are a clear sign that cabbage white butterflies have been in your garden.
- Physical barriers: Covering your crops with netting or fine mesh can prevent adult butterflies from laying their eggs on the plants.
- Diversion planting: Planting some decoy plants like nasturtiums or marigolds can attract cabbage white butterflies away from your edible greens.
- Beneficial insects: Certain insects, such as parasitic wasps (Cotesia) and ladybugs, feed on cabbage white caterpillars. By encouraging these beneficial insects to reside in your garden, you can naturally control the pest population.
- Handpicking: If you spot cabbage white caterpillars on your plants, remove them by hand and relocate them to a different area, away from your crops.
If the damage has already been done, there are still ways to control the outbreak:
- Chemical control: If you prefer to use chemicals, there are insecticides available specifically designed to target cabbage white caterpillars. Follow the instructions on the package carefully and use them as a last resort.
- Physical traps: Setting up traps to catch adult cabbage white butterflies can reduce the number of eggs laid in your garden. These traps can be made by placing a shallow dish with soapy water or a vinegar solution in your garden.
- Late planting: Cabbage white butterflies are most active in the spring. By planting your cabbage and other brassicas later in the season, you may be able to avoid the worst of the infestation.
- Monitoring: Regularly check your plants for signs of cabbage white caterpillars and take action as soon as you notice any. Early intervention is the key to stopping an infestation.
Although cabbage white caterpillars can be a nuisance, it’s worth remembering that they are part of the natural ecosystem. By implementing preventive measures and being vigilant about controlling their population, you can enjoy a thriving garden without resorting to harsh chemicals.

The dreaded cabbage white
The cabbage white butterfly, also known as the cabbage moth or cabbage butterfly, is a small white butterfly that can cause significant damage to cabbage and other members of the brassica family. These butterflies are perfectly adapted to create problems for gardeners who grow cabbage, cauliflower, and other brassicas.
When planting brassicas, it’s important to be aware of the cabbage white butterfly’s presence. To identify them, look for white butterflies with black spots on their wings. The eggs are often laid on the underside of leaves, so be sure to inspect the leaves and midribs for signs of eggs or small green caterpillars.
If you spot any cabbage white worms on your plants, it’s important to take action to protect your crop. There are several ways to treat cabbage worms, both naturally and using chemical methods. Some gardeners prefer to use organic methods, such as companion planting with garlic or creating diversion plants to attract the butterflies away from the main crop. Others may choose to use chemical insecticides as a last resort.
However, there are several natural remedies to control and get rid of cabbage worms. The first step is to manually remove any worms or eggs from the plant. You can do this by handpicking them off the leaves or using a gentle jet of water to dislodge them. If the infestation is large, you may need to treat the plants with a natural insecticide, such as neem oil or a garlic spray.
Another method to protect your plants from cabbage worms is to cover them with a physical barrier, such as floating row covers or fine mesh netting. These barriers prevent the butterflies from laying their eggs on the plants, reducing the risk of infestation. It’s important to remove the covers once the butterflies have finished laying their eggs to allow for pollination.
Understanding the lifecycle of the cabbage white butterfly can also help in preventing infestations. These butterflies lay their eggs on the underside of leaves, where the caterpillars hatch and begin feeding on the plant. As they grow, the caterpillars can cause significant damage to the leaves and heads of the plants. Once they reach maturity, the caterpillars pupate and emerge as adult butterflies, continuing the lifecycle.
Growing beneficial plants, such as dill or nasturtiums, can help attract insects that prey on cabbage worms, providing a natural form of control. Additionally, the scent of certain plants, such as tansy or wormwood, may deter the butterflies from laying their eggs on the plants.
In conclusion, the cabbage white butterfly can be a nuisance for gardeners growing cabbage and other brassicas. However, by following the proper preventative measures and utilizing natural remedies, such as manual removal and physical barriers, it is possible to control and eliminate cabbage worms without resorting to chemical insecticides. Remember, prevention is key, so being proactive in protecting your plants from infestations will help ensure a healthy and bountiful harvest.
How do you prevent caterpillar attacks
To prevent caterpillar attacks and protect your home vegetables from being destroyed, there are several general methods for preventing these pests from munching on your crops. By implementing these strategies, you can enjoy a healthy and thriving garden without the hassle of dealing with caterpillars.
- 1. Plant decoy greens: Planting decoy plants like Nasturtiums, which caterpillars love to eat, can divert their attention away from your main crops.
- 2. Use physical barriers: Create a barrier around your plants using fine mesh or row covers to prevent adult butterflies from laying eggs on the crops.
- 3. Encourage beneficial insects: Attract and encourage the presence of beneficial insects like ladybugs and lacewings, which are natural predators of caterpillars.
- 4. Practice crop rotation: Rotate your crops each year to disrupt the life cycle of caterpillar larvae and prevent the build-up of pests in your garden.
- 5. Handpick caterpillars: Regularly inspect your plants and handpick any caterpillars you find, dropping them into soapy water to prevent them from returning.
While these preventive measures can go a long way in warding off caterpillar attacks, it is important to note that some butterfly species, like the cabbage butterfly (Pieris brassicae), may still find their way into your garden. If that happens, consider using natural and organic methods, such as garlic spray or onion spray, to deter them from laying eggs on your plants.
By following these tips and staying vigilant, you can create a butterfly-friendly garden while preventing caterpillar damage to your valuable crops.
