Deer can turn a thriving garden into a buffet overnight. A deer proof fence is the most reliable long-term solution to protect your plants. But not all fences work equally. In this guide, we break down the best materials, installation steps, and common mistakes to help you build a fence that actually keeps deer out.
Why a Deer Proof Fence is Your Best Option
Deer are persistent and agile. They can jump up to 8 feet high and squeeze through small gaps. Repellents and scare devices often stop working after a few weeks. A physical fence, when built correctly, provides 24/7 protection without ongoing costs. The key is height, strength, and proper installation.
Types of Deer Proof Fences: Pros and Cons
1. Polypropylene Mesh Fence
Lightweight, UV-resistant, and easy to install. Ideal for large areas. Choose 7.5 to 8 feet tall. Pros: affordable, invisible from a distance. Cons: can be damaged by falling branches or heavy snow.
2. Woven Wire Fence (e.g., deer netting)
Stronger than mesh, often made of galvanized steel. Use 2x4 inch openings to prevent deer from pushing through. Pros: durable, low maintenance. Cons: more expensive, harder to install.
3. Electric Fence
Uses a low-amperage shock to deter deer. Often combined with a bait line (peanut butter on aluminum foil). Pros: very effective, less visual impact. Cons: requires regular maintenance (battery, vegetation clearance), not suitable for areas with pets or kids.
4. Slanted or Double Fence
Two shorter fences (5-6 feet) spaced 3-4 feet apart, or a single fence angled outward at 45 degrees. Pros: deer hesitate to jump over a wide gap or angled barrier. Cons: uses more land, higher material cost.
How to Install a Deer Proof Fence: Step-by-Step
Step 1: Measure and Plan
Determine the perimeter. For a mesh or wire fence, buy rolls that are at least 7.5 feet tall. Mark the corners with stakes.
Step 2: Set Posts
Use 8-foot treated wood or metal T-posts spaced 8-10 feet apart. Dig holes 2 feet deep, set posts, and fill with concrete. Ensure posts are vertical.
Step 3: Attach the Fence
For poly mesh: unroll along the fence line, attach with zip ties or staples. Keep tension. For wire: use tension bands and clips. Leave a few inches at the bottom to secure with ground staples.
Step 4: Secure the Bottom
Deer can crawl under if there’s a gap. Bury the bottom 6-12 inches or use ground stakes to pin it tight. Alternatively, lay large rocks along the base.
Step 5: Add a Gate
Install a self-closing gate with a latch that deer cannot open. Make sure the gate is as tall as the fence.
Common Mistakes and How to Avoid Them
Mistake #1: Fence too short. Deer can clear 6 feet easily. Always go 7.5-8 feet. For high-pressure areas, use 10 feet.
Mistake #2: Leaving gaps. Deer will squeeze through any opening larger than 6 inches. Check for sagging sections and repair immediately.
Mistake #3: Using flimsy materials. Cheap plastic netting degrades in sun and deer can push through. Invest in UV-stabilized poly or galvanized wire.
Mistake #4: Forgetting the gate. A sturdy gate is critical. Many homeowners secure the fence but leave the gate weak or open.
FAQ
Q: What height fence keeps deer out?
A: At least 7.5 feet. For jumpers, 8 feet is safer. Slanted or double fences can work at 5-6 feet.
Q: Can deer jump a 6 foot fence?
A: Yes, easily. A 6-foot fence is only a minor obstacle for most deer.
Q: Is electric fence safe for pets?
A: Electric fences designed for deer deliver a low-current shock that is unpleasant but not harmful. However, it's best to keep pets away or train them.
Q: How much does a deer proof fence cost?
A: Poly mesh fencing costs about $0.50-$1 per linear foot, while wire fencing runs $1-$3. Installation adds labor if you hire out. DIY saves money.
Final Thoughts
A deer proof fence is an investment that pays off season after season. Choose a height of at least 7.5 feet, use durable materials, and install carefully. Avoid common pitfalls like short fences or poor gates. With the right setup, you can enjoy a beautiful garden without deer damage.
