As you wander through your beautiful garden, you notice something alarming – something is eating your corn stalks! What could it be? A myriad of potential culprits come to mind: could it be pesky insects, gnawing rodents, or maybe even some larger, more surprising intruders?
These unsightly bites and holes in your plants are signs that you’re not the only one who enjoys your cornstalks. Identifying the offender isn’t always an easy task, but not to worry- as you continue reading, you’ll learn about the various garden foes that could be at the root of your problem.
What Is Eating My Corn Stalks?
The most common pests that are likely eating your corn stalks are corn borers and corn earworms. Corn borers are small worm-like insects that bore into the stalks, while corn earworms tend to eat the silks and kernels. Some larger animals like raccoons and deer could also be a possible cause if they are present in your area.
– Ants
| Description | Small, social insects that build nests near plants, feed on corn leaves, and may attract other pests. |
|---|---|
| Damage | Wood damage, weakened structure. |
| Control | Implement physical barriers, such as sticky traps or diatomaceous earth, around the base of plants and use natural repellents to deter ants from accessing and damaging corn stalks. |
Corn stalks can potentially be damaged by a variety of pests, but if we’re focusing on ants, their impact is usually indirect. Ants tend to farm aphids, scale insects, and mealybugs because they produce honeydew, a sweet substance that ants enjoy. These pests, if left unchecked, can feed on your corn stalks and reduce their vigor.
Controlling Ants can be done with baits, dusts, or insecticidal soaps. You can place baits near active ant trails to poison the colony. Insecticidal soaps can be sprayed directly on visible ants and around the base of your corn plants to discourage ants from climbing.
Using natural predators, such as ladybugs or lacewings, can aid in controlling these pests as they feed on aphids and other insects that attract ants. Additionally, maintaining a healthy and clean garden can discourage these pests from invading your corn stalks.
Lastly, avoid overwatering and ensure well-drained soil. Standing water or overly moist conditions can attract ants.
Remember that not all ants are harmful to plants, and some species might even be helping your garden by feeding on other pests. Make sure to correctly identify the ant species before starting any control methods.
– Aphids
| Description | Small, soft-bodied insects with pear-shaped bodies, often found in clusters, sucking the sap from corn stalks, causing stunted growth. |
|---|---|
| Damage | Stunted growth and curled leaves. |
| Control | Implement natural predators, like ladybugs, and spray a mixture of water and dish soap to deter aphids from infesting corn stalks. |
One potential culprit eating your corn stalks could be aphids. Effect of Aphids: Aphids are tiny bugs that have a huge appetite for various types of plants, including corn stalks. They suck the sap from plants, which can result in curled and yellowing leaves, stunt growth, and overall plant weakening.
Moreover, aphids can spread plant diseases, which may further damage your corn plants. Since aphids multiply rapidly, an infestation can quickly become devastating for your corn crop.
Control Measures: Ensuring a well-balanced ecosystem in your garden, which includes aphid predators like ladybugs and lacewings, is the first line of defense. However, for more serious infestations, you might need to resort to insecticidal soaps or neem oil. These are sprayed directly onto the aphids, thereby eliminating them and minimizing the risk of damage to your corn plants. Always apply treatments in late evening to avoid harming beneficial insects. Regular monitoring of your corn plants and immediate action upon noticing aphids is key to controlling them.
For preventing future infestations, consider pest-resistant varieties of corn and rotate your crops annually. Remember, healthy soil equals healthy crops that can better resist pests.
– Deer
| Description | Large herbivorous mammal with long legs, hooves, and antlers, known for devouring corn stalks and damaging crops. |
|---|---|
| Damage | Defoliation and destruction of corn stalks. |
| Control | Implement physical barriers (fencing, netting) or use repellents (sprays, scents) to deter deer from consuming corn stalks. |
How Deer Affects Corn Stalks
Deer are one of the pests that eat corn stalks. They usually damage young plants, and the evidence suggests that the stalk has been ripped or broken off. They feed on the tender leaves and ears, causing significant damage to corn fields.
Ways to Protect Corn Stalks from Deer
To protect your corn stalks from deer, consider installing a tall fence, at least 8 feet in height, around your garden. Deer are excellent jumpers, so the fence needs to be high. Another option is deer repellents; these can be purchased in various forms such as sprays and pellets. Using these around your corn stalks can help keep the deer away. Remember to reapply after heavy rain or at least once a month. A good home remedy is using fragrant soap bars hung around the garden; deer dislike strong scents. You might also try motion-activated sprinklers which can startle deer away.

– Raccoons
| Description | Large, nocturnal mammals with ringed tails that are causing significant damage to corn stalks. |
|---|---|
| Damage | Significant destruction to corn stalks, resulting in reduced crop yield. |
| Control | Install fencing around the corn field and use deterrents like noise makers or motion-activated sprinklers to deter raccoons. |
Raccoons are notorious thieves in the vegetable garden, with sweet corn being their specialty. They have a keen sense of when corn is ripe and will often feast on it the night before it is set to be harvested. They are known to climb the stalks and pull the ears down to eat, causing significant damage to plants in the process.
Damage Effects: Raccoons will damage corn stalks by breaking or bending them over to reach the ears. This not only robs you of your harvest but can potentially kill or weaken the plant due to the stress. You may begin to notice missing ears and disturbed soil around the plants, or see the corn tops torn and the ears partially eaten with the husks left behind.
Solutions: There are a few effective preventative and repellent measures that you can take to protect your corn from raccoons. Installing a two-strand electric fence about 12 inches high can deter them. Sprinkling blood meal around your garden or using commercial repellents can also discourage them from entering. For a more passive approach, you could try planting a few extra rows of corn as a sacrificial offering to keep them away from your main crops.
Trapping and Relocation: In areas where it is legal, you can trap raccoons and remove them from the area. Always check with local authorities before trapping and relocating wildlife.
Please know that any interaction with wildlife should be carried out with utmost care, and preferably by a licensed professional to avoid harm to both the animal and the person.
