8 Organic Ways to Get Rid of Cabbage Worms & Cabbage Moths

But I have good news: there are many easy ways to stop cabbage worms from destroying your garden, and still reap a beautiful, bountiful harvest!Before we dive into the ways to control cabbage moth damage in the garden, let’s briefly familiarize ourselves with these pesky little jerks.“Cabbage worms” is a relatively generic term that refers to a handful of species of small green pest caterpillars.Some cabbage worms are the larvae of small white butterflies, seen flitting around gardens during the day.If you notice white butterflies dancing around your garden, they’re probably laying eggs, and thus creating future destructive cabbage worms.The caterpillars will continue to eat and grow for several weeks, until they’re old enough to form a chrysalis and transform into a cabbage white butterfly (or moth).Manual Removal Floating Row Covers Plant Purple & Red Varieties Use Polyculture & Companion Planting Beneficial Insects Decoy Moths Bacillus Thuringiensis (Bt) Spray Neem Oil Spray.I used to be a bit more squeamish, but the fact of the matter is: manually squishing or removing certain pests right when you see them is sometimes the most quick, easy and effective way to stop them in their tracks.This includes hand-picking cabbage worms and caterpillars from brassicas and leafy greens (which the chickens greatly appreciate, wink wink…) or squishing colonies of aphids.I also know some gardener friends that nab cabbage moths with butterfly nets and tennis rackets!To reduce damage from cabbage worms by hand, you’ll need to inspect your plants frequently.When you’re out on the hunt, keep in mind that cabbage worms are most often found on the underside of leaves, or tucked in the new growth at the plant’s center.Sneaky cabbage worms will also lay along the center vein of a kale leaf, blending in and perfectly disguised.Individual plants, raised beds, or sections thereof can be protected with row covers, traditionally supported on hoop structures.We use them in our garden to prevent cabbage worm damage as well as protect tender young seedlings from wild birds.With the addition of these base extenders, they also fit well across our widest beds (4.5 feet), though they stay fairly short.To provide more “head room” or arch over larger plants like Brussels sprouts and tomatoes, the hi-rise super hoops would work best.It is easy to pull back the row cover material when needed (e.g. for harvesting) and simply leave the hoops in place.If you use the right material and tuck the corners and sides in tight (we use clothes pins for this), row covers can effectively keep out cabbage moths and their caterpillars, along with many other pest insects.Row covers may also protect your plants from squirrels, rabbits, birds, neighborhood cats, and other larger vertebrate pests too!Additionally, variety and polyculture – the term for mixing many types of plants in one space – reduces the chances of widespread devastation by pests that are all attracted to the same crop.For example, brassica companion plants like thyme, dill, oregano, lavender, onions, garlic, and marigolds are said to deter cabbage moths.On the other hand, some companion plants can serve as a “trap crop” and attract cabbage worms – while luring them away from your veggies!However, be sure to periodically remove infested trap crop plants to prevent a booming population of cabbage moths in your garden.For more information on companion planting combinations and natural pest deterrents, be sure to subscribe to our weekly newsletter to receive a free garden planning toolkit!I hand-picked all of these cabbage worms from a potted nasturtium, planted as a trap crop at the end of a bed of collard greens and kale.Parasitic wasps lay their eggs inside or on top of other arthropods, including caterpillars and their pupae.Bt is naturally found on leaves and in soil worldwide, and has been used commercially both in organic and conventional agriculture for over fifty years.Over two decades of review, the EPA and numerous scientific bodies have consistently found that Bt and Bt-crops are not harmful to humans.” Entomological Society of America.When applied to vegetable crops, Bt is considered safe for human consumption even if sprayed the same day as harvest.Yet Bt is even more mild than others, and doesn’t pose the same risk for accidentally burning leaves with improper applications.Concentrated neem oil is diluted and mixed, and then sprayed onto plants for organic pest control.Neem oil is particularly effective at controlling small soft-bodied insects, like aphids, thrips, spider mites, mealybugs, scale, and white flies.Therefore, routinely spraying your garden with a neem oil solution may make your plants less attractive to pests.Used in conjunction with other control methods, neem oil can help the problem – but will not likely prevent or eliminate the presence of cabbage moths entirely.If you want to use neem oil in your garden, I highly suggest you read this article to learn more about how to properly mix and use it.Because neem combats fungal diseases like powdery mildew and doesn’t harm beneficial insects (when used correctly), it can be a great product to use in an organic garden! .
