Get rid of cabbage worms right away if you spot them, their eggs, or any of their droppings. A very small crop will remain if you just let them grow on their own.
Fortunately, there are a number of all-natural and organic methods for eliminating cabbage worms from the garden. Let’s talk about:
Remove Cabbage Worms and Eggs By Hand
This is a good approach to get rid of the icky crawlies, depending on how repulsed you are by them. You can even involve your children (I know my children love to pull the caterpillars off of our plants).
The eggs are small, oblong, and white or yellowish, as was before indicated. You should only see single eggs, though. It’s more likely that a cluster of tiny, rectangular white or yellow eggs put together are ladybug eggs, which you don’t want to remove or destroy because they are a natural adversary of the problem you’re attempting to solve.
The caterpillars can either be removed, placed in a small container, and later fed to your backyard hens, or you can take them and place them in a bucket of soapy water.
Cabbage worms can be easily eliminated using cornmeal. You can just water your plants and liberally sprinkle them with cornmeal. The worms will consume the cornmeal, which will make them enlarge and eventually kill them.
Homemade Cabbage Worm Spray
1 teaspoon of soap and 1/4 cup vinegar should be combined with 3/4 cups of water. It will adhere to the leaves easier with the soap. Spray sparingly over the tops and bottoms of the leaves.
Make sure your plants are not young, small seedlings, and that you don’t completely saturate the leaves before using this spray. Additionally, I advise testing it on a tiny portion of the plant (just in case) and spraying it at night rather than during the hottest part of the day (which can cause your plants to bake in the sun).
I’ve used this spray for several years and haven’t had any problems at all, although I just put a small amount on older plants at night. Although it does contain vinegar, a natural pesticide (and excellent weed killer), I’ve never experienced any problems with this diluted spray.
Spray With Bt
A number of garden pests can be eliminated with the natural pesticide Bacillus thuringiensis, or Bt for short. This bacterium is naturally present in soil and has long been employed in organic farming and gardening.
The easiest technique to get rid of cabbage worms naturally is with Bt because it is only hazardous to the larvae of butterflies and moths and is not toxic to birds or other mammals.
Bt is available as a ready-to-spray product or as a concentrate that must afterwards be diluted with water.
Every two weeks or so, you can spray Bt on your plants to get rid of any pests you might have. There won’t be many worms left, and if there are some, you can easily pluck them off or wash them away. It can be sprayed as early as the day of harvest without having any negative effects because it is thought to be safe for human consumption.
Try Spraying Plants or Worms with Neem Oil
Caterpillars and other soft-bodied pests in the garden can be eliminated with the help of the amazing natural pesticide neem oil (like aphids). To get rid of the cabbage worms, spray it directly on them.
In order to prevent butterflies and moths from laying their eggs on the plants, neem oil can also be sprinkled on them. Neem oil is best used in conjunction with other techniques because, like some of the other preventatives I’ve described below, it isn’t likely to totally address your problem.
Use ducks to eat the worms
When given the chance, ducks, hens, and even songbirds will consume the worms and butterflies. So, let them inside.
I strongly advise ducks instead of chickens since they won’t eat your cabbage if it’s mature. They adore eating cabbage worms and will certainly do so if given the chance.
Symbiosis is an idea that I adore. allowing the natural world to function as it normally would. So let your garden visitors—your ducks or some songbirds—do their thing.
Will cabbage worms be eliminated by baking soda?
Cabbage worm removal is a challenging task. The most frequent queries gardeners have regarding getting rid of cabbage worms in their garden are listed here.
Are Cabbage Worms Harmful To Humans?
Humans are not harmed by cabbage worms. Cabbage doesn’t harbor any hazardous pests. You won’t perish if you mistakenly eat a cabbage worm, so don’t be concerned. Although it may not be tasty, it is not at all dangerous.
Will Dish Soap Kill Cabbage Worms?
While spraying plants with a soapy water mixture won’t kill cabbage worms, dropping them in a pail of soapy water will. Because dish soap-covered leaves are less appealing to worms, spraying it on your plants will keep them away.
Will Baking Soda Kill Cabbage Worms?
Baking soda won’t kill cabbage worms on its own, but if you sprinkle your plants with an equal mixture of baking soda and flour, it works well.
Combine one cup of flour and one cup of baking soda, then generously apply the mixture to your affected plants. Repeat if it rains or is watered upon because the latter will wash it away.
Does Boiling Kill Cabbage Worms?
It’s unsettling for gardeners who are concerned about eating their cabbage heads because a myth about cabbage worms claims that not even boiling will get rid of them.
Be assured that cabbage worms are killed by boiling. Cabbage worms will perish if you plan to blanch and freeze cabbage heads. The worms will perish if the water is heated for any other reason. Insects cannot tolerate boiling.
Will Vinegar Kill Cabbage Worms?
Cabbage worms cannot be killed by vinegar on its own, although it can be used to deter them. Vinegar is a potent remedy for these pests when combined with other chemicals.
In a spray bottle, combine 1/4 cup white vinegar, 3/4 cup water, and 1 teaspoon dish soap. Spray your plants liberally to deter cabbage worms.
Plant the Right Companion Plants
By choosing the best neighboring companion plants, it is possible to completely thwart the cabbage worm. To prevent the Cabbage White Butterfly from detecting your cole and brassica crops, you need something strongly perfumed (brussels sprouts, broccoli, cabbage etc).
To act as nurseries for beneficial insects, put a row or several sections of beneficial plants throughout your beds. Parasitic wasps, praying mantises, and green lacewings are examples of useful insects.
The following companion plants aid in warding off cabbage worms:
To help ward against cabbage worms early on, plant these crops around your cabbages. Precautions are always worthwhile!
Plant Trap Crops
It appears that nasturtiums are the cabbage worms’ preferred plant food. They will look for nasturtiums to lay their eggs on, which will develop into little worms that will mature into large, green ones that will ravage your plants.
I like to move any parasitized cabbage worms I find to my trap nasturtiums so the parasitic wasps can help me control the cabbage worm population.
Additionally, I’ve grown trap crops in cinder block beds so I could burn them! harsh but accurate if plants have heavy pest infestations before any beneficial insects have taken up residence. To be quite honest, it was enjoyable to use the blocks to put out the fire.
Use Sticky Traps
Always sow trap crops and hang sticky traps as well. It is very good to mix up the crops so that the Cabbage White doesn’t have a smorgasbord to quickly mow down and to companion plant the crops to provide homes for helpful insects. The aroma of the mustards, cole crops, and brassicas is covered up by the companion plants.
The cabbage worms are caught in the sticky traps. Do these two things if nothing else.
Use the Right Sprays
While we aim to stay away from chemical pesticides, there are a few other organic sprays that are allowed for controlling cabbage worms, including Neem Oil, bT, and even soapy water. Spraying the undersides of your leaves, where eggs and worms hide, is crucial when utilizing a spray. Also liberally spray your cabbage heads.
BT (Bacillus Thuringiensis) spray works quickly to address the problem over the long run since the bacteria persists. Its nontoxicity to bees and mammals is an extra bonus. For usage instructions, refer to your container. Additionally, you can pump some into any areas where it is obvious that a cabbage looper has bored into your plants.
Spraying Bt WILL harm monarch caterpillars, so use caution. You can help monarchs if you have the room by providing a secure area for them apart from any overspray.
Use Row Covers
I advise using floating row covers if you grow your cabbages in a row or in a raised garden bed. When the plants are planted in the garden, you may buy them or make your own tullestarting, and you can keep them until the last cabbage is harvested.
A complete 6-inch headspace is required on both sides and at the top of the height. Eggs shouldn’t be laid through the tulle and right on your vegetables.
Here’s a quick and simple method to cover your raised garden bed to keep pests out and lengthen the growing season.
Hand Pick to Get Rid of Cabbage Worms
The most time-consuming method of eliminating cabbage worms is to look around your garden, move leaves, remove worms, squash eggs, and plant more herbs in pots all over the beds while you work. This time MUST be spent in the garden.
Plant Red / Purple Cabbages
The 0 time tip is to only grow red or purple cabbage and to stay away from green cabbage. On my red cabbages, I’ve never noticed any cabbage worms. I think it’s because the color makes the caterpillars plainly visible, preventing them from using camouflage.
Can cabbage worms be killed by Dawn dish soap?
Picking them by hand is one of the best, most organic ways to treat cabbage worms on your plants. It may seem like a lot of work at first, and it is. But if you work hard, the issue will go gone quite quickly.
They have excellent concealment skills. They are nearly identical in color and usually eat the undersides of the leaves. So, at first, it may be challenging to see them, especially when they are tiny young caterpillars.
Most likely, you’ll locate their frass (also known as faeces) before the caterpillars. Near plant holes or on the leaves below, cabbage worm droppings resemble green sawdust or tiny green balls. If you turn the holy leaf over, you’ll probably discover the offender (s).
You can remove them with just your bare hands because they don’t sting or bite. Wear gloves instead if you find it repulsive. If you come across any eggs or cocoons while looking for caterpillars, you should remove them.
Put cabbage worms into a pail of soapy water to destroy them. They are unable of swimming and will finally perish in the sea. But the soap will quickly put them to death. If you’re not too grossed out, you could always just smush them without bothering with soapy water.
Spray Neem Oil To Get Rid Of Cabbage Worms
Neem oil, a naturally occurring insecticide, can be used safely on plants and kills caterpillars when they feed on the leaves. Additionally, it has a lasting impact, so you don’t need to spray your plants every day.
Neem oil takes some time to kill cabbage worms since it needs to absorb into their systems. They will be killed more quickly if a mild liquid soap is added to the mixture.
Try Bacillus Thuringiensis (BT) To Treat Caterpillars
A naturally occurring soil-dwelling bacteria called Bacillus thuringiensis (BT) is frequently employed as a biological pesticide. BT is quite effective at getting rid of cabbage worms, cabbage loopers, and other plant-eating caterpillars.
Simply spritz it on the affected plants’ leaves. The caterpillars will immediately cease feeding after consuming it. Even so, it can take a few days for them to pass away.
Use Insecticidal Soap Spray To Kill Cabbage Worms
Caterpillars will be instantly killed by insecticidal soap. So if you’re too shy to hand pick them, this is a nice substitute. It has no lasting impact and only acts when sprayed directly on cabbage worms.
You can manufacture your own organic insecticidal soap or purchase one already made. I make my own by combining 1 liter of water with 1 teaspoon of mild liquid soap.
As soon as you notice damage, spray the leaves; the soap will kill both the eggs and the small caterpillars. Spray underneath the leaves as well, as this is typically where they hide.
Do cabbage worms get killed by garlic spray?
A: Something is eating holes in the leaves of my broccoli, kale, and Brussels sprout plants, which I have planted in my garden. Is there anything I can use to cure the plants without risk? The use of pesticides on my food worries me.
The most likely culprit for the holes is either the imported cabbageworms or the cabbage loopers. Check for eggs and/or caterpillars if you notice white or olive-colored moths flitting above your plants. You might spot an adult moth, eggs, a caterpillar, or a chrysalis in your yard because these insects undergo a complete transformation. By consuming foliage, the caterpillars cause damage. They can nearly completely destroy a planting in the event of severe infestations. You can try a number of home remedy-style therapies as well as a biological insecticide. Use insecticidal soap, red pepper or garlic spray, or both. These treatments can be manufactured at home. Six drops of a mild, non-grease-cutting dish detergent are added to two liters of water to create the insecticidal soap. Making the garlic and red pepper spray involves adding water, a drop of mild dish detergent, and the juice of one clove of garlic or one tablespoon of ground red pepper. Make sure to spray both the top and bottom leaf surfaces. You will need to reapply because rain will wash this treatment away. Neem oil, pyrethroids, and bacillus thuriensis (bT) are further efficient insecticides. To ensure a plentiful crop of nutritious produce, keep an eye out for signs of imported cabbageworms and cabbage loopers in your garden.
How can cabbage worms be eliminated naturally?
“A few species of small, green nuisance caterpillars are referred to as cabbage worms, a very generic name. They are drawn to the mustard and cabbage plant families the most, as their names imply. This group of vegetables, also referred to as the brassica family, includes turnip greens, mustard greens, broccoli, kale, collard greens, brussels sprouts, and, of course, cabbage. But there’s more than that! In our garden, we have discovered cabbage worms on a wide range of other plants, including flowers.
Some cabbage worms are the offspring of tiny white butterflies, which can be observed throughout the day flying about gardens. Despite the fact that they aren’t actually moths at all, the white butterflies are frequently referred to as “cabbage whites” or “cabbage moths.” The cabbage looper, a similar caterpillar, does, in fact, come from a brown nocturnal moth. Butterfly cabbage worms and cabbage loopers are similar in appearance, although cabbage loopers often have a thinner body and travel around more slowly.
Plants themselves are not immediately harmed by cabbage moths or butterflies. Their larvae are placed in charge of that enjoyable task “worms! If you see white butterflies flitting around in your garden, they are most likely laying eggs that will eventually develop into nasty cabbage worms. Cabbage moths frequently rub their buttocks on plant leaves as they land to lay eggs.
Eggs laid by cabbage moths resemble oblong white or yellow spots. Almost always, they are fastened to the underside of leaves. Squishing these eggs if you find them and recognize them is a fantastic early control approach! Though they are found in bunches, ladybug eggs are also oblong and yellow. Eggs of cabbage worms are typically scattered and solitary.
The cabbage worms start feeding on the nearby plant debris as soon as the larvae of cabbage moths and butterflies hatch from their eggs. As the caterpillars increase in size and population, this causes little holes to appear in the leaves, which evolve into larger holes or fully destroyed leaves and plants.
Although some cabbage worm damage is merely ornamental, it can nonetheless be disastrous to young, delicate seedlings. For several weeks, the caterpillars will keep eating and developing until they are mature enough to make a chrysalis and change into a cabbage white butterfly (or moth).
Here are a few natural strategies to get rid of cabbage worms in your garden now that you are more aware of their life cycle. Below, we’ll go over each of them.
- Manual Extraction
- Overhead Row Covers
- Plant Purple and Red Plants.
- Utilize companion planting and polyculture
- Positive Insects
- fake moths
- Spray for Bacillus Thuringiensis
- Neem Oil Mist
