What are the signs of vegetable cutworm infestation?

Vegetable cutworms can cause significant damage to plants, so it’s important to be able to identify the signs of their infestation. One common sign is finding young seedlings or transplants that have been cut off at ground level. You may also notice wilted or damaged leaves, as well as holes or tunnels in the stems of plants. Additionally, you might come across the presence of dark-colored droppings or caterpillars hiding in the soil near the base of the plants.

Signs of Vegetable Cutworm Infestation Damage to Plants Presence of Cutworms
Holes or notches on leaves and stems Cutworms feed on the base of plants, causing them to wilt or die Find cutworms curled up in the soil around the base of plants
Young seedlings may be severed at ground level Plants may appear stunted or have slow growth Some cutworm species leave behind droppings called frass
Cutworms may feed at night and hide during the day Cutworms may cut off the entire plant from the base Look for dark-colored, smooth-skinned caterpillars

How can I prevent vegetable cutworm infestation in my garden?

To prevent vegetable cutworm infestation in your garden, there are several measures you can take. One effective method is to use physical barriers such as collars made from cardboard or plastic around the base of young plants. These barriers should extend a few inches into the soil to prevent the cutworms from reaching the stems. Another preventive measure is to remove any garden debris or weeds that could provide hiding places for the pests. Additionally, practicing crop rotation and maintaining good garden hygiene can help reduce the risk of infestation.

  • Remove weeds and debris: Keep your garden clean and free from weeds, as they can attract cutworms. Regularly remove any plant debris or fallen leaves that can serve as hiding places for the pests.
  • Use physical barriers: Create a physical barrier around your plants by placing collars made of cardboard or aluminum foil around the base of the stems. This will prevent the cutworms from reaching the plants and laying eggs.
  • Encourage natural predators: Attract beneficial insects and animals to your garden, such as ground beetles, birds, and toads, which feed on cutworms. Plant flowers and herbs that attract these predators and provide them with a suitable habitat.

What are natural predators of vegetable cutworms?

Natural predators play an important role in controlling vegetable cutworm populations. Some common predators include birds, such as robins and sparrows, that feed on the caterpillars. Ground beetles and parasitic wasps are also known to prey on cutworms. Encouraging these beneficial insects and birds to visit your garden can help keep the cutworm population in check. Providing birdhouses, water sources, and planting native flowering plants can attract these predators to your garden.

How do vegetable cutworms affect vegetable crops?

Vegetable cutworms can have a detrimental impact on vegetable crops. They feed on the stems of young plants, causing them to wilt, droop, or even die. This can result in stunted growth and reduced yield. In severe infestations, entire rows of plants may be destroyed. Additionally, cutworms can introduce bacteria or other pathogens into the wounds they create, further compromising the health of the plants.

Eat through the stems and leaves of vegetable plants, causing wilting and stunted growth. Presence of cut or damaged leaves, plants falling over, and chewed stems. Implementing physical barriers like collars around plants, handpicking and destroying cutworms, using insecticides.
Feeding can lead to the death of young seedlings and reduce crop yield. Noticing cutworms curled up in the soil during the day and active feeding at night. Cultivating the soil to expose cutworm pupae, practicing crop rotation, attracting natural predators.
Can cause economic losses and affect the overall health of vegetable crops. Seeing cutworms feeding on various vegetable plants like tomatoes, peppers, and cabbage. Maintaining good garden hygiene, removing weeds and plant debris, monitoring and early detection.

What are the life cycle stages of vegetable cutworms?

The life cycle of vegetable cutworms consists of several stages. It begins with adult moths laying their eggs on plant leaves or stems. These eggs hatch into small caterpillars that start feeding on the nearby vegetation. As they grow, the caterpillars go through several molts, shedding their old skin and growing larger each time. Eventually, they enter the pupal stage where they transform into adult moths. Understanding the life cycle of cutworms can help in developing effective control strategies.

The life cycle stages of vegetable cutworms include eggs, larvae, pupae, and adult moths.

What are some organic methods to control vegetable cutworms?

If you prefer to use organic methods to control vegetable cutworms, there are several options available. One approach is to introduce beneficial nematodes into the soil, as these microscopic organisms can target and kill cutworm larvae. Another method is to apply natural insecticides derived from substances like Bacillus thuringiensis (Bt), which specifically target caterpillars without harming beneficial insects. Additionally, handpicking and removing the caterpillars from plants can be an effective organic control method.

Some organic methods to control vegetable cutworms include using floating row covers, handpicking, applying beneficial nematodes, and using insecticidal soaps.

Which vegetables are most susceptible to cutworm damage?

Some vegetables are more susceptible to cutworm damage than others. Brassicas, such as cabbage, broccoli, and cauliflower, are often targeted by cutworms. Other commonly affected vegetables include tomatoes, peppers, potatoes, and lettuce. However, it’s important to note that cutworms can feed on a wide range of plants, so it’s essential to monitor all your vegetable crops for signs of infestation.


Tomatoes are highly susceptible to cutworm damage. Cutworms feed on the stems of young tomato plants, often severing them completely at the soil level. This can lead to stunted growth or even death of the plant. To protect tomato plants from cutworms, it is recommended to use physical barriers such as collars or to apply organic insecticides.


Cabbage plants are also prone to cutworm damage. Cutworms can chew through the stems of young cabbage plants, causing them to wilt and eventually die. It is important to monitor cabbage plants closely and take preventive measures such as using collars or applying biological controls to reduce cutworm infestations.


Broccoli plants can be affected by cutworms as well. These pests can cause severe damage by feeding on the stems of young broccoli plants, leading to stunted growth and reduced yield. To protect broccoli plants from cutworms, it is recommended to use physical barriers, such as collars, and to practice crop rotation to disrupt their life cycle.
