Protecting Your Property & Wildlife: A Guide to Double Fence Deer Control
As someone who’s spent over a decade exploring and writing about the American outdoors, I’ve seen firsthand the challenges deer can present – not just to gardens and landscaping, but also to agricultural operations and even the health of deer populations themselves. The increasing human-wildlife conflict often leads property owners to seek effective deterrents, and a double fence deer system, sometimes called a deer double fence or hot zone fence, is frequently the most reliable solution. This article will delve into everything you need to know about installing and maintaining a double fence for deer, ensuring both property protection and responsible wildlife management.
Understanding the Deer Problem & Why Double Fencing Works
Deer are beautiful creatures, but their browsing habits can be incredibly destructive. They impact gardens, farms, nurseries, and even young tree plantations. Traditional single fences often prove ineffective, as deer are surprisingly adept at jumping over them. According to the National Park Service, deer can clear fences up to 8 feet high with relative ease, especially when motivated by food sources. This is where the concept of a double deer fence comes in.
The principle behind a double fence is psychological. It doesn’t rely on height, but on disrupting a deer’s natural jumping behavior. Deer assess a potential jump based on depth perception and perceived landing space. A double fence creates an illusion of insufficient landing space, making them hesitant to attempt the jump. Think of it as a visual trick that leverages their instincts. It’s a non-lethal, humane method of control, aligning with the principles of responsible wildlife management advocated by organizations like Leave No Trace.
The Psychology of Deer Jumping: Why Single Fences Fail
Deer naturally want a clear landing zone when jumping. A single fence presents a clear path. A double fence for deer, however, presents two fences a short distance apart. This creates a perceived barrier that disrupts their depth perception and makes them unsure of where they’ll land. They’re less likely to risk a jump if they don’t feel confident about a safe landing.
Designing Your Double Fence System: Key Considerations
Building an effective deer double fence isn’t just about putting up two fences. Careful planning is crucial. Here’s what you need to consider:
- Fence Height: While not as critical as with single fences, both fences should be at least 4-6 feet high.
- Spacing: This is the most important factor. The space between the two fences should be between 3-6 feet. A narrower gap (3 feet) is generally more effective, but may be more expensive to implement.
- Materials: Woven wire, high-tensile wire, or even plastic netting can be used. Consider the aesthetics and durability needed for your specific location.
- Posts: Use sturdy posts, spaced appropriately for the chosen fencing material. Corner posts should be particularly robust.
- Gates: Gates are a necessary evil. Ensure they are also double-fenced or designed to prevent deer from simply walking around them.
Hot Zone Fence Variations: Adding an Electrical Component
For areas with particularly persistent deer pressure, a hot zone fence – a double fence with an electric wire strung between the two – can be incredibly effective. The electric shock isn’t meant to harm the deer, but to provide a negative reinforcement that discourages them from even approaching the fence. Always follow local regulations regarding electric fencing. The USDA Forest Service often has information on regulations related to fencing on or near federal lands.
Installation: A Step-by-Step Guide
While professional installation is always an option, many property owners can tackle this project themselves. Here’s a general outline:
- Planning & Layout: Mark the fence line carefully, considering terrain and potential obstacles.
- Post Installation: Set the posts, ensuring they are plumb and securely anchored.
- Fence Attachment: Attach the fencing material to the posts, maintaining consistent tension.
- Second Fence Installation: Repeat steps 2 and 3 for the second fence, maintaining the correct spacing.
- Gate Installation: Install double-fenced gates or gates designed to deter deer.
- (Optional) Electric Wire Installation: If using a hot zone fence, install the electric wire and energizer, following manufacturer’s instructions and safety guidelines.
Important Safety Note: When working with fencing materials and tools, always wear appropriate safety gear, including gloves, eye protection, and sturdy footwear.
Maintenance & Troubleshooting
A double fence deer system isn’t a “set it and forget it” solution. Regular maintenance is essential to ensure its continued effectiveness.
- Vegetation Control: Keep vegetation trimmed around the fences to prevent it from shorting out electric wires (if applicable) and providing deer with a boost to jump over the fence.
- Fence Inspection: Regularly inspect the fences for damage, such as broken wires, loose posts, or gaps.
- Gate Maintenance: Ensure gates are functioning properly and securely closed.
- Electric Fence Check (if applicable): Regularly check the voltage of the electric fence to ensure it’s delivering an adequate shock.
Dealing with Determined Deer: When the Fence Isn't Enough
Occasionally, a particularly determined deer may attempt to breach the fence. If this happens, identify the weak point and reinforce it immediately. Consider adding additional bracing or increasing the spacing between the fences in that area. Sometimes, simply adding visual deterrents, like brightly colored flagging tape, can discourage further attempts.
Cost Considerations: What to Expect
The cost of a deer double fence varies depending on the materials used, the length of the fence, and whether you hire professional installation. Here’s a rough estimate (prices as of late 2023):
| Component | Estimated Cost |
|---|---|
| Posts (per post) | $10 - $30 |
| Woven Wire (per foot) | $3 - $8 |
| High-Tensile Wire (per foot) | $1 - $3 |
| Electric Fence Energizer | $100 - $500 |
| Professional Installation (per foot) | $8 - $20 |
These are just estimates. It’s always best to get quotes from local fencing suppliers and installers.
Alternatives to Double Fencing
While a double fence for deer is often the most effective solution, other options are available, though generally less reliable:
- Repellents: Deer repellents can be effective, but require frequent reapplication, especially after rain.
- Motion-Activated Sprinklers: These can startle deer, but they may become accustomed to them over time.
- Plant Selection: Choosing deer-resistant plants can reduce browsing damage, but won’t eliminate it entirely. See REI Expert Advice for plant suggestions.
Conclusion: Protecting Your Investment & Coexisting with Wildlife
Investing in a double fence deer system is a significant step towards protecting your property and crops. It’s a humane and effective solution that allows you to coexist with deer while minimizing damage. By carefully planning, installing, and maintaining your fence, you can enjoy the beauty of the outdoors without the frustration of constant deer browsing. Remember to always prioritize responsible wildlife management and adhere to local regulations.
