Why Do Squirrels Target Corn Gardens?
Understanding why squirrels are attracted to your corn garden is the first step in effective prevention.
- Corn is a high-energy food source: Squirrels rely on calorie-rich foods, and corn provides the perfect combination of carbohydrates and sugars.
- Easy accessibility: Corn grows in clusters, making it easy for squirrels to grab multiple ears quickly.
- Seasonal behavior: Squirrels tend to intensify feeding during late summer and fall, preparing for winter.
Knowing these motives helps tailor your defense strategies to address the root of the problem.
Effective Physical Barriers to Keep Squirrels Out
Physical barriers provide a direct and reliable way to protect your corn crop.
1. Use Wire Mesh or Hardware Cloth
- Material: Choose galvanized hardware cloth with 1/2-inch or smaller openings to prevent squirrels from squeezing through.
- Application:
- Wrap individual corn stalks or the entire garden perimeter.
- Create a fence at least 3 feet high, as squirrels can jump.
- Benefits: Durable and long-lasting; does not harm animals.
2. Install Netting Over Corn Ears
- Purpose: Protects ears from being directly accessed.
- Method:
- Use bird netting or garden mesh.
- Secure tightly around the ear with twist ties or clips.
- Tip: Check regularly to avoid trapping beneficial wildlife.
3. Raised Garden Beds with Enclosures
- Elevating your garden and enclosing it can reduce squirrel access.
- Use wooden frames with mesh sides and top covers.
Natural and Humane Repellents That Work
If you prefer a non-physical approach, several natural repellents can discourage squirrels.
1. Plant Squirrel-Repelling Herbs
- Peppermint and garlic: Strong scents deter squirrels.
- Hot peppers: Capsaicin in peppers irritates squirrels’ senses.
- How to use: Plant these herbs around your corn garden or create a spray by mixing crushed peppers and garlic in water.
2. Use Commercial Squirrel Repellents
- Look for products containing natural ingredients like capsaicin or predator urine.
- Apply according to label instructions, reapplying after rain.
3. Sprinkle Blood Meal or Human Hair
- Blood meal emits an odor that can deter squirrels.
- Human hair placed around the garden mimics predator presence.
Modify Your Garden Environment
Changing how and where you plant can reduce squirrel visits.
1. Diversify Plantings
- Mix corn with other plants squirrels dislike, such as daffodils or marigolds.
- This can confuse and discourage squirrels from settling.
2. Harvest Corn Early
- Pick ears as soon as they mature to limit feeding opportunities.
- Early harvesting reduces the time squirrels have to target your crop.
3. Remove Food Sources Nearby
- Keep bird feeders away from the garden to avoid attracting squirrels.
- Clean up fallen nuts, fruits, or seeds that may entice squirrels to linger.
Additional Tips to Keep Squirrels Away
- Motion-activated sprinklers: These startle squirrels and condition them to avoid your garden.
- Ultrasonic repellents: Emit sounds unpleasant to squirrels but inaudible to humans.
- Trapping and relocation: If legal and humane in your area, live traps can catch and allow relocation of squirrels.
Common Questions About Squirrel Control in Corn Gardens
Can I use poison to get rid of squirrels in my garden?
Using poison is not recommended due to risks to pets, wildlife, and humans. It is also often illegal and unethical. Opt for humane, non-lethal methods instead.
How high should a fence be to keep squirrels out?
A fence should be at least 3 feet tall, with hardware cloth buried 6 inches underground to prevent digging.
Are squirrels beneficial to my garden?
Yes, squirrels help disperse seeds and aerate soil, but their feeding habits can harm crops. Balancing control with coexistence is key.
