What Is Eating My Corn

If you’ve been wondering, “What is eating my corn?“, you’re not alone. This is a common concern amongst gardeners worldwide, who often find their beautiful corn plants mysteriously nibbled on. There could be a host of culprits behind this aggravating issue.

Whether you’re a veteran gardener or a newbie, it’s essential to learn about the potential pests that may be parasitizing your corn crop. Dealing with these invaders is not always easy, but the first step is always identifying them.

What Is Eating My Corn?

The most common pests that are likely eating your corn are corn earworms, European corn borer, and corn rootworms. These insects are known for damaging corn by eating the silk, kernels, and even burrowing into the stalks. Close examination of your corn plants can help you determine which of these pests is causing the problem.

– Mice️

Description Small rodents with sharp teeth, known for nibbling on corn leaves and kernels, causing damage to the plant.
Damage Chewing leaves, causing wilting and stunted growth.
Control Implement physical barriers, such as wire mesh or fences, and use natural deterrents like peppermint oil or owl decoys.

Mice Damage to Corn Plants:
Mice can pose a significant challenge to your corn plants. Mice enjoy gnawing on the stalks, leaves, and husks, causing physical damage. When they get to the corn cob, they will eat the kernels, impacting your crop yield.

Solutions to Mice Problems:
Implementing mouse control strategies can mitigate the issue. One effective method is placing traps around your garden in areas where the mice frequently visit. Metal barriers or fencing can also be installed around the garden, as mice have difficulty climbing slick surfaces. Additionally, natural predators such as cats can be helpful deterrents. Regularly clean the garden area to eliminate potential nesting spots for the rodents.

Additional Preventive Measures:
Crop rotation can be a useful strategy to prevent recurring mice problems. Switching to a different crop can disrupt their food source, causing them to move away. Planting certain types of plants that mice don’t like near your corn can also deter them.

– Rats

Description Small rodents that have sharp teeth, feed on various parts of corn plants, and cause extensive damage to crops.
Damage – Rats cause extensive damage by gnawing on the plant stems and roots, leading to stunted growth and possible death of the corn plants.
Control Implement physical barriers, such as wire mesh or fences, and use natural deterrents like peppermint oil or predator urine.

Rats are a common pest that can cause significant damage to your corn crops. They can consume the kernels, causing the ears to look gnawed or chewed on. Typically, they eat the corn from the top down, removing entire rows of kernels, which can lead to reduced yields. They can also cause damage by gnawing on the stalks and roots, which can stunt growth and lead to plant death.

Effects of Rat Infestation: Rats can significantly reduce your corn yields by consuming the kernels and damaging the stalks and roots. This can stunt the growth of your plants and even lead to plant death.

To prevent rat damage, one practical approach is to use rodent baits or traps. These can be strategically placed around the perimeter of your corn field. It’s crucial to regularly check and replace these traps to ensure effectiveness. Physical barriers such as metal rat guards on the stalks of corn plants can also deter rats. Lifestyle changes like removing potential nearby food sources and shelters can discourage rat populations from establishing in the first place.

Solutions to Rat Infestation: The effective control of rats involves the strategic placement of rodent baits or traps, installing physical barriers such as metal rat guards, and lifestyle changes like eliminating potential rat food sources and shelters.

– Squirrels️

Description Small rodents with bushy tails, known for their sharp teeth and agility, causing damage to corn plants.
Damage Chewed leaves, broken stems, missing kernels, and damaged corn ears.
Control Implement physical barriers like fences or netting, use repellents, plant companion crops, and remove attractants to deter squirrels from consuming corn.

The pest damaging your corn is likely a squirrel. Squirrels are notorious for damaging agricultural crops including corn. They cause harm by gnawing on the corn cobs, often removing entire kernels, and leaving partially eaten cobs behind. This results in a significant loss in yield.

To prevent squirrel damage: you can install a mesh or wire fence around your corn field. This barrier makes it difficult for squirrels to get to the crop. Also, consider adding a predator decoy, such as owl or hawk statues, near your corn field. Squirrels perceive these as threats and this can help scare them away. Alternatively, you can use repellents formulated to deter squirrels. In extreme cases, trapping may be necessary, but this should be carried out in accordance with local wildlife regulations.

– Birds

Description Small-sized, avian pest with sharp beaks that feed on corn, causing damage to leaves, kernels, and overall plant health.
Damage Corn crops are being ravaged by birds, leading to significant damage.
Control Use physical barriers like netting or scare tactics such as reflective objects to deter birds from eating corn.

Birds can cause significant damage to your corn crop. They have a particular fondness for sweet corn, specifically once the silk becomes visible at the end of the ears. Birds peck at the silk and then proceed to eat the kernels, causing not only damage to the crop, but also rendering it less visually appealing. This pecking can also open the crop to secondary fungal infestations.

Damage Significant crop loss and destruction of corn plants.
Control Implement fencing or use repellents, such as predator urine or noise devices, to deter deer from accessing and damaging corn plants.

Deer are a common pest that can be a significant problem for corn crops. These animals are particularly fond of ripe corn and can cause extensive damage by eating the kernels straight off the cob. Tags: Deer, Corn, Damage

Besides eating the corn, their feeding activity can also affect the overall health of the plant by causing stress and potentially spreading diseases. This means that deer not only directly damage your crops but indirectly compromise the plants’ ability to grow healthily in the future too. Tags: Disease, Overall health, Indirect damage

To discourage deer from eating your corn, several strategies can be employed. One effective way is to install a tall fence around your corn patch, as deer are poor climbers. Another approach is to use deer repellents, available in many gardening stores, that discourage deer from approaching the area due to unfavorable smells or tastes. Furthermore, you can try using scare devices such as motion sensor sprinklers that startle the deer, making them less likely to visit your garden again. Tags: Fence, Deer repellents, Scare devices

– Rabbits

Description Small mammals that feed on corn plants, causing damage by nibbling on the leaves and stalks.
Damage Chewed leaves and stems, stunted growth, and potential destruction of the entire plant.
Control To prevent and control rabbits from eating our plants, use physical barriers like fences or netting around the garden.

Rabbits are particularly damaging pests for corn as they eat the leaves and stalks. They feast on young shoots, which hinders corn growth and directly impacts its yield.

Damage by Rabbits: These agile creatures have sharp teeth that chew and cut through the stems, affecting the plant’s ability to gain water and nutrients, which ultimately leads to its death or substandard performance.

You can combat the rabbit problem in a few ways: Fencing is a reliable solution, but make sure it is minimum 1 meter high and buried about 15-30cm into the ground to prevent them from digging under it. Another method is using humane traps to relocate them far from your property. Commercially available repellents (choose organic to be environmentally friendly) are also helpful. Lastly, encouraging the presence of natural predators, like hawks and foxes, can help control rabbit population.

– Insects (such as corn earworms or corn borers)

Description Destructive insects that feed on corn plants, causing damage to the ears and stalks.
Damage Severe crop damage leading to reduced yield and quality.
Control Implement integrated pest management strategies, including crop rotation, biological control, and pesticide application, to prevent and control damage caused by the pests.

Corn Earworms: Corn earworms are a common pest infesting corn crops. These insects, in their larval state, eat through a kernel of corn to the cob.
They start by attacking the silk, which they use as a path to crawl down into the corn cob itself. Once inside, they will start to consume the kernels, which can lead to significant yield losses.
Solution: Control measures include insecticidal treatments applied when silks emerge. An appropriate insecticide should be selected and sprayed directly onto the silks for maximum control effectiveness. Regular scouting ahead of peak moth activity is also essential.
Another option is to use a biological control method, such as Trichogramma wasps, which are natural predators of corn earworm eggs. Additionally, growing corn varieties resistant to corn earworm can significantly reduce the damage these pests cause.

Corn Borers: Another common pest in corn crops is the corn borer. It bores into the stem of the corn plant, causing internal damage which weakens the plant and causes stalks to break.
Significant feeding damage can also result in yield loss due to poor kernel development.
Solution: To deal with corn borers, applications of Bt (Bacillus thuringiensis) corn varieties have shown successful control. These genetically modified corn varieties naturally produce proteins toxic to corn borers.
Alternatively, targeted applications of insecticides are an effective control measure. These need to be timed correctly, ideally just after eggs have hatched but before larvae enter the stalks to feed. Frequent field monitoring is, therefore, crucial.

– Raccoons

Description Large, omnivorous mammals with masked faces and dexterous paws that are feeding on our corn crops.
Damage Raccoons cause extensive damage to corn plants by eating the crops and destroying the entire plant.
Control Install fences or use motion-activated devices to deter raccoons from accessing and damaging corn plants.

Raccoons are known to be one of the primary pests that target corn crops.
Impact of Raccoons on Corn: These nocturnal animals are not just interested in the corn; they are capable of devastating an entire corn crop overnight. Raccoons have a unique style of feeding where they pull the corn down to the ground, rip open the husk, and eat the kernels right off the cob.

Solutions to Raccoon Infestation: Typically, the best solution to protect corn crops from raccoons is to use a combination approach. This includes the use of repellents, fencing, and trapping. Repellents can deter raccoons from the area, but must be frequently reapplied. Fencing, especially an electric one can effectively keep raccoons out, but it may be a costly and labor-intensive option. The benefit is that it’s a long-lasting solution. Trapping and releasing them in a far off area is another alternative, but be cognizant of local laws and regulations on trapping wildlife.

Remember to always clean up after harvesting to discourage raccoons and other pests from moving in.

– Groundhogs️

Description Install fences or use motion-activated devices to deter raccoons from accessing and damaging corn plants.
Damage Decimated crops, leading to significant yield loss and financial impact.
Control Implement fencing and scare tactics, such as noise or motion devices, to deter groundhogs from accessing and damaging corn plants.

Groundhog Impact on Corn
Groundhogs, also known as woodchucks, are a common pest to encounter in gardens and they pose a significant threat to corn crops. These animals are attracted to the sweet taste of corn and will typically begin feeding on corn plants during their tasseling stage. Groundhogs will chew through the stalks, having the capacity to decimate entire patches of corn if left unchecked.

Groundhog Control Methods
To protect your corn crops from groundhogs, a mix of prevention and direct control methods can be implemented. Fencing your field is one of the most efficient ways; install a wire mesh buried at least a foot deep underground with the fence standing 3-4 feet tall to prevent climbing. Additionally, traps can be used to catch and relocate the groundhogs. You can also resort to repellents, either commercial ones or home remedies like Epsom salts spread around the plants. Lastly, efficient control of groundhog population requires managing the area around your garden – minimize cover, such as woodpiles or high grass, as they are ideal hiding spots for groundhogs.

– Wild boars

Description Large, omnivorous mammals known for their destructive feeding habits, targeting corn crops with their strong snouts and tusks.
Damage Devastates crops, destroys plant roots, and leaves fields in ruins.
Control Install sturdy fences around the cornfield, use repellents such as strong scents or noise, and employ scare tactics like scarecrows or flashing lights.

Damage by Wild Boars
Wild boars, notorious agricultural pests, can wreak havoc on your corn crop. They typically root around in the soil, trampling and damaging plants in the process. They also eat the corn directly, especially when the corn is in its milk stage. This can significantly reduce your crop yield and overall productivity.

Control Measures for Wild Boars
To protect your corn from wild boars, one effective strategy is installing sturdy electric or woven wire fences around your crop. These must be properly maintained to ensure their effectiveness. Scare devices like motion-activated lights or noise makers can also deter wild boars. In some areas, hunting or trapping may be allowed. However, always make sure to follow local wildlife regulations. Applying repellents specifically designed for wild boars can also help keep them at bay. Regularly inspect your fields for signs of wild boar activity to quickly identify and address any problems.
