Cutworms are a type of caterpillar that can cause extensive damage to plants, particularly young seedlings. There are a number of ways to deter or repel these pests, including using physical barriers, traps, and certain types of plants. Some plants that have been shown to be effective at repelling cutworms include marigolds (Tagetes spp.), nasturtiums (Tropaeolum majus), and petunias (Petunia spp.).

These plants produce chemicals that are toxic to cutworms or make the environment unsuitable for them to survive. Planting these around your garden can help reduce the population of cutworms and minimize damage to your plants.

Cutworms are one of the most destructive pests in the garden, causing serious damage to young plants. But there are a few plants that repel these destructive little creatures. One of the best plants for repelling cutworms is marigolds.

Marigolds release a chemical into the soil that is toxic to cutworms and other pests. They also have a strong scent that deters many pests. Another great plant for repelling cutworms is nasturtiums.

Nasturtiums also release chemicals into the soil that are toxic to cutworms and other pests. They also have a strong scent that deters many pests. Finally, garlic is another great plant for repelling cutworms.

Do Coffee Grounds Deter Cutworms?

If you’re a gardener, you know that cutworms can wreak havoc on your plants. These sneaky little pests can be hard to spot, and by the time you see the damage they’ve done, it’s often too late. Cutworms feast on young plants, cutting them off at the stem and causing them to wilt and die.

If you’re looking for a natural way to deter these pests, coffee grounds may do the trick. Coffee grounds are rich in nitrogen, which is beneficial for plants. But cutworms don’t like the acidic environment that coffee grounds create.

When used as a mulch or added to the soil around your plants, coffee grounds can help to deter these pests. You can also make a spray using diluted coffee grounds and water, which can be applied directly to plants that are at risk of being attacked by cutworms. While there’s no guarantee that coffee grounds will completely keep cutworms away from your garden, it’s definitely worth giving them a try!

How Do I Get Rid of Cutworms in the Garden?

Cutworms are one of the most common pests in gardens. They are the larvae of night-flying moths and are usually black or brown in color. Cutworms can be a major problem for gardeners, as they feed on young plants and can cause extensive damage to crops.

Fortunately, there are a number of ways to get rid of cutworms in the garden. One way to control cutworms is to use Bacillus thuringiensis (BT), a naturally occurring bacterium that is deadly to them. BT can be purchased as a spray at most garden centers.

Simply mix it according to the directions on the package and apply it to your plants. This method is safe for both people and animals and will not harm beneficial insects such as bees and ladybugs. Another way to kill cutworms is by using diatomaceous earth (DE).

DE is a powder made from fossilized algae that is sharp enough to slice through an insect’s exoskeleton. It works by causing dehydration, so it is important to apply it when the weather is dry. DE can be found at most hardware stores or online retailers specializing in gardening supplies.

Be sure to wear a dust mask when applying DE, as it can irritate your lungs if inhaled. If you have persistent cutworm problems, you may need to take more drastic measures such as tilling your soil before planting each season. Tilling exposes the pupae of cutworm moths to predators such as birds which helps reduce their population over time.

What Kills Cutworms Naturally?

Cutworms are caterpillars that feast on the leaves of plants, and can cause serious damage to crops. Luckily, there are a few natural ways to kill these pests. One way to kill cutworms is to use diatomaceous earth.

This powder is made from the fossilized remains of algae, and when it comes into contact with an insect’s body, it cuts through their exoskeleton and dries them out. You can apply diatomaceous earth directly to the soil around your plants, or mix it with water and spray it on the leaves. Another option is to use beneficial nematodes.

These tiny worms live in the soil and hunt down cutworms, injecting them with a bacteria that kills them. You can purchase beneficial nematodes online or at some garden stores. You can also make your own cutworm killer by mixing together Equal parts flour and saltpeter (potassium nitrate).

Apply this mixture to the base of plants where cutworms are likely to be found. The flour will attract the cutworms while the saltpeter will kill them.

How Do You Control Cutworms Organically?

Cutworms are the larvae of moths and can be a real problem in gardens, eating holes in leaves and stems and often causing young plants to collapse and die. If you’re looking for an organic way to control cutworms, here are a few ideas to try. One of the best ways to keep cutworms from becoming a problem in your garden is to start with clean, weed-free soil.

Cutworms love nothing more than feasting on weeds and other leafy greens, so getting rid of these will help discourage them from taking up residence in your garden beds. Another good tip is to protect young plants with collars made from cardboard or stiff paper. Simply cut a ring out of cardboard or paper and place it around the base of the plant, making sure that the top of the collar is buried an inch or two below the soil surface.

This will create a barrier that cutworms can’t penetrate, stopping them from getting at your plants. If you already have a cutworm problem, there are a few things you can do organically to control them. One option is to handpick them off your plants and drop them into a bucket of soapy water; this will kill them quickly and effectively.

Another option is to use diatomaceous earth, which is a powder made from fossilized algae that cuts through the exoskeletons of insects like cutworms, killing them on contact. Just be sure not to apply diatomaceous earth directly to any plants you plan on eating as it can be harmful if ingested.

Plants That Repel Cutworms


Epsom Salt for Cutworms

Epsom salt is an effective home remedy for cutworms. Simply mix together 1/2 teaspoon of Epsom salt with 2 cups of water and pour it into the affected area. The cutworms will be drawn to the solution and will drown.

Signs of Cutworms

Cutworms are one of the most destructive pests of gardens and crops. The larvae (caterpillars) of these moths feed on plant leaves and stems, causing extensive damage. Cutworms are particularly problematic for young plants, as they can completely destroy a seedling in just a few days.

There are several signs that cutworms may be present in your garden or crop: 1) Damage to plants – Look for chewed leaves or stem damage on your plants. This is typically the first sign that cutworms are present.

2) Cutworm “moths” – These insects are actually a type of nocturnal moth. If you see them flying around your garden at night, it’s a good indicator that cutworms are present. 3) Soil disturbance – Another telltale sign of cutworms is soil that has been disturbed by their burrowing activities.

This can look like small craters in the ground or loose dirt near the base of plants.

Baking Soda for Cutworms

If you’re looking for a natural way to get rid of cutworms in your garden, baking soda may be the answer. Cutworms are destructive pests that can quickly decimate a young plant’s leaves and stems. While there are several chemical-based products on the market to kill these pests, many gardeners prefer to use more natural methods.

Baking soda is one such method that is safe for both people and plants. To use baking soda as a cutworm killer, simply sprinkle it around the base of affected plants. The powder will then act as a physical barrier, preventing the worms from getting to the plant’s foliage.

You can also add some baking soda to a spray bottle filled with water and spritz affected plants with this mixture. This will help to further deter cutworms from feeding on your plants. While baking soda is an effective pest control measure, it’s important to keep in mind that it won’t discriminate between good and bad insects.

So if you have beneficial insects in your garden (such as ladybugs), be sure to avoid spraying them with the baking soda solution.

How to Get Rid of Cutworms Naturally

Cutworms are one of the most destructive pests in gardens and landscapes. These voracious little creatures can decimate a crop overnight, leaving behind only ragged stalks and shredded leaves. If you’ve ever had cutworms in your garden, you know how frustrating they can be.

But there is hope! There are a number of effective ways to get rid of cutworms naturally, without resorting to harsh chemicals. One of the best ways to control cutworms is to encourage their natural predators.

Birds, snakes, and lizards all enjoy feasting on these tasty morsels. So make your garden as inviting as possible for these helpful critters by providing shelter and food sources. birdhouses, water features, and piles of brush will all help attract predators to your yard.

Another great way to keep cutworms at bay is to simply hand-pick them off your plants. This may sound like a tedious task, but it’s actually quite satisfying (and cathartic!) To do this, simply wait until dusk when the worms are active and then go out into your garden with a flashlight and a bucket. Pick the worms off your plants and drop them into the bucket.

Then dispose of them in whatever way you see fit (composting them is always a good option). There are also a number of organic products on the market that can help control cutworms. Bacillus thuringiensis (BT) is a bacteria that specifically targets caterpillars and other soft-bodied insects like cutworms.

It’s available in both liquid and granular form, so you can choose whichever application method works better for you. Another popular option is diatomaceous earth (DE), which is an abrasive powder that cuts through an insect’s exoskeleton, causing it to dehydrate and die within 48 hours . DE is safe for humans and animals but deadly for insects; just be sure not wear gloves when applying it so you don’t get any on your skin!

Does Cornmeal Kill Cutworms

Cornmeal is an effective, natural method for controlling cutworms. Cutworms are the larvae of moths and are destructive pests of vegetables, fruits, and ornamentals. They feed on plants at night, cutting them off at the base or stems.

This can kill young plants or severely damage larger ones. Cornmeal is a good option for controlling cutworms because it is safe for people and pets, eco-friendly, and inexpensive. Here’s how to use cornmeal to control cutworms:

Sprinkle cornmeal around the base of plants that are susceptible to attack from cutworms. The cornmeal will act as a barrier, preventing the worms from getting to the plants. Reapply after rain or watering.

Cutworms are attracted to light, so you can also trap them by placing a small container (such as a yogurt cup) filled with cornmeal near infested plants. The worms will crawl into the container and be unable to get out. Empty the container regularly and dispose of the worms in soapy water.

Cutworm Moth

Cutworm moths are a type of moth that is known for its destructive larvae. The larvae of these moths are known to feed on the leaves of plants, and they can cause significant damage to crops. Cutworm moths are found in many parts of the world, and they can be a serious pest to farmers.

In order to control these moths, farmers often use pesticides. However, some farmers are now using biological controls, such as parasitic wasps, to control cutworm moths.

How to Prevent Cutworms

Cutworms are one of the most common pests that can affect your garden. They are the larvae of moths and can cause serious damage to your plants, especially young seedlings. Cutworms typically feed at night, so you may not notice the damage until it’s too late.

Fortunately, there are a few things you can do to prevent them from wreaking havoc in your garden. Here are a few tips for preventing cutworms: 1. Use floating row covers or insect netting over your plants to keep cutworms from getting to them in the first place.

This is especially effective when used in combination with other methods listed below. 2. Make sure to clean up any debris in your garden before planting. This includes removing dead leaves, weeds, and other organic matter that could serve as a food source for cutworms.

3. Plant resistant crops whenever possible. Some plants that are less susceptible to cutworm damage include marigolds, nasturtiums, and petunias. 4. Use bait traps to lure and kill cutworms before they have a chance to do any damage.

You can make your own bait trap by setting out a piece of cardboard or wooden board overnight near where you think they might be active.

Cutworm Life Cycle

Cutworms are the caterpillars of various species of night-flying moths. The adult moths are dull gray or brown and often have patterned wings. They lay their eggs on leaves, in cracks in the bark of trees, or on the ground near food sources for the caterpillars.

The eggs hatch within a week and the tiny caterpillars begin to feed immediately. They go through several growth stages, or instars, shedding their skin each time they outgrow it. During this time, they can do a lot of damage to crops and gardens.

Full-grown cutworms are usually about 1-1/2 inches long. They vary in color from light gray to black, but all have dark stripes running along their sides. At this point, they stop feeding and begin to pupate.

This is when they form a hard shell around themselves and transform into moths. The entire life cycle from egg to adult takes about 4-6 weeks depending on the temperature and availability of food. Cutworms can have multiple generations per year under ideal conditions.


In conclusion, there are many plants that can help deter cutworms from attacking your garden. Some of these include marigolds, nasturtiums, and tansy. You can also try planting some of these around the perimeter of your garden to create a natural barrier.

By doing this, you can help keep your garden healthy and free of pests.
