How to Get Rid of Corn Root Worms (Natural & Organic Methods)

By Sabrina Wilson / August 1, 2022

The corn rootworm is a damaging pest of corn. The adult corn rootworm is a small beetle that feeds on the leaves of corn plants. The larvae (young form) of the corn rootworm feed on the roots of corn plants. The corn rootworm can cause significant damage to corn crops. The corn rootworm is difficult to control because it has a high reproductive rate and can quickly develop resistance to pesticides.

There are several reasons why natural or organic methods are preferable for getting rid of corn root worms. First, corn root worms are difficult to control with chemical pesticides, and often develop resistance to them over time. Second, chemicals can potentially harm other insects, animals, and even humans if they are not used properly. Third, natural methods are often more effective in the long run, since they do not create resistance in the pests. Finally, using natural methods is better for the environment and for sustainable agriculture.

Beneficial Nematodes

Beneficial nematodes are a type of parasitic worm that can be used to control corn rootworm populations. The nematodes seek out and kill the corn rootworm larvae, preventing them from damaging the roots of the corn plants. To use beneficial nematodes, you will need to purchase a package of them from a gardening or home improvement store. Mix the nematodes with water according to the package directions, then drench the soil around the base of the corn plants with the mixture. The nematodes will then enter the soil and search for the corn rootworm larvae. Once they find the larvae, they will penetrate their bodies and release a bacteria that will kill them. The nematodes will then move on to other larvae, repeat the process, and eventually reduce the overall population of corn rootworms.

Neem Oil

To get rid of corn root worms, mix 4 teaspoons of neem oil with 1 cup of water. pour this mixture into a spray bottle and shake well. Then, spray the neem oil mixture onto the corn plants, being sure to coat the roots. Repeat this process every 7-10 days until the corn root worms are gone.

Insecticidal Soap

Insecticidal soap is typically made from a fatty acid, such as lauric acid, and a potassium hydroxide salt. The fatty acid works by dissolving the oils and waxes that make up an insect's exoskeleton, while the potassium hydroxide disrupts the insect's cell membranes. Insecticidal soap is effective against most soft-bodied pests, including aphids, mealybugs, thrips, whiteflies, and young scale insects. It usually must be applied directly to the pests to be effective.

Insecticidal soap is an effective method for controlling corn root worm populations. This IPM strategy can be used as a standalone method or in combination with other IPM techniques such as crop rotation and soil burial. When using insecticidal soap, it is important to follow the directions on the label and target the application to the corn root system. This will help to minimize the impact on beneficial insects and other organisms in the soil.

Horticultural Oil

Insecticidal soaps are made up of potassium salts of fatty acids. When these potassium salts are mixed with water, they act as a surfactant and break down the surface tension of water. This allows the soap to penetrate the waxy outer layer of an insect's exoskeleton and break down its cell membranes. Insecticidal soap is effective against a wide range of insects, including aphids, whiteflies, and spider mites. It can be used on fruits, vegetables, and ornamentals.

If you're looking to get rid of corn root worms, horticultural oil is a great option. Simply mix the oil with water according to the manufacturer's instructions, and then apply it to the affected area. Be sure to cover the entire root system, as this is where the worms reside. The oil will kill the worms, allowing your plants to thrive.


What are corn rootworms?
corn rootworms are a type of beetle that feeds on the roots of corn plants.

What damage do corn rootworms cause?
Corn rootworms can cause extensive damage to corn plants, resulting in yield loss. The larvae of corn rootworms feed on the roots of corn plants, which can lead to the plants being unable to take up nutrients and water properly. The damage done by corn rootworms can also make the plants more susceptible to disease and pests.

What is the life cycle of a corn rootworm?
Adult corn rootworms lay their eggs in the soil near corn plants. The eggs hatch into larvae which begin to feed on the roots of the plants. The larvae mature into adults and emerge from the soil to mate and lay more eggs.

Where do corn rootworms come from?
Corn rootworms are found in cornfields throughout the United States.

How can I control corn rootworms?
There are a number of ways to control corn rootworms, including the use of pesticides, crop rotation, and planting resistant varieties of corn.
