# Alpaca Fencing Options: Predator Deterrence and Containment ## Key Takeaways - **Minimum fence height of 48 inches is recommended for adult alpacas, with 60 inches advised in areas of high predator pressure (e.g., coyotes, dogs) to prevent jumping and deter larger threats.** Effective height is measured from the ground, necessitating secure attachment to prevent gaps. - **No-climb woven wire with mesh openings of 2x4 inches or smaller is the superior material for predator deterrence, preventing ingress by smaller predators and entanglement.** This is contrasted with standard field fence, which offers less protection due to larger mesh sizes. - **Securing the bottom of the fence is critical; burying it 6-12 inches or ensuring it is taut against the ground prevents predators from digging underneath.** Adding a strand of electric wire 4-6 inches above ground level can further deter digging attempts. - **Hybrid fencing systems, combining physical barriers like woven wire with electric deterrents (e.g., top or bottom strands), offer a cost-effective balance of containment and predator deterrence.** Electric wires act as a psychological barrier, discouraging animals from testing the fence. - **Regular monthly inspections (and post-storm checks) are essential for identifying and rectifying fence integrity issues such as sagging, rust, holes, or vegetation contact with electric wires.** Proactive maintenance prevents breaches and ensures ongoing protection. - **Proper installation of corner and gate posts, including robust bracing, is paramount as these points bear significant tension and are common weak points for predator ingress.** Gates must be at least 48 inches tall with secure latches and no gaps underneath. --- Choosing the right alpaca fencing is one of the most important decisions you will make as an alpaca owner. The fence you install must do two jobs at once: keep your alpacas safely inside their pasture and keep predators out. This guide compares the main fencing materials and designs used for alpacas, explains how fence height and construction affect predator deterrence, and walks through the practical steps of planning, installing, and maintaining a fence that protects your herd. It is written for new alpaca owners who are building their first pasture, as well as experienced farmers who are replacing or upgrading an existing fence line. ## At a Glance - **Fence height:** Plan for at least 48 inches for adult alpacas. Use 60 inches in areas with heavy predator pressure or where coyotes and dogs are common. - **Best predator deterrent:** No-climb woven wire with openings of 2 by 4 inches or smaller. Add a top rail or strand of electric tape to prevent climbing. - **Bottom of the fence:** Secure the wire to the ground or bury it 6 to 12 inches to stop predators from digging underneath. - **Electric options:** A single hot wire at 18 to 24 inches above the ground adds a strong psychological deterrent. A full electric fence works well but requires regular maintenance. - **Field fence vs. woven wire:** Standard 4-point field fence is cheaper but less predator-resistant. No-climb woven wire is the better choice for predator protection. - **Gates:** Use sturdy metal gates at least 48 inches tall with secure latches. Predators and alpacas both test gates. - **Inspect monthly:** Walk the entire fence line at least once a month and after every major storm. Look for sagging, rust, holes, and vegetation touching electric wires. - **Call for help:** Contact your extension agent or a [livestock fencing](/knowledge/animal-farming/alternative-livestock/livestock-fencing-materials-comparison) specialist before you buy materials if you are unsure about your soil type, predator pressure, or local regulations. ## Why Alpaca Fencing Is Different Alpacas are not like cattle or sheep. They do not push hard on fences, and they rarely try to break through a barrier. A fence that simply keeps them in a pasture might be enough for containment alone. But alpaca fencing has a second job that is just as important: predator deterrence. Dogs, coyotes, foxes, and even large birds of prey can threaten alpacas, especially crias (baby alpacas) and juveniles. A fence that keeps alpacas in but lets a determined dog or coyote through is a fence that has failed at its primary purpose. Alpacas have a strong flight response. When they are frightened, they run. A fence that they can see through clearly is less stressful for them than a solid barrier, because they can see what is on the other side and determine whether a threat is real. This is one reason woven wire and other open fence designs are preferred over solid wood or metal panels for alpacas. Another difference is that alpacas are lighter than cattle and do not put the same kind of pressure on fence posts and rails. This means you can use lighter-weight posts and materials than you would for cattle. However, the fence still needs to be strong enough to stop a predator that is much heavier and more determined than an alpaca. A fence built to the minimum standard for alpaca containment may not be strong enough to stop a coyote. The terrain where you keep alpacas also matters. Alpacas are sure-footed and do well on a variety of pasture types, but the fence must follow the ground closely. Gaps under the fence are an invitation to predators. On uneven ground, you will need to adjust the fence line or use a bottom wire that can be tensioned to follow the contour of the land. ## Understanding Predator Pressure Before you choose a fencing system, you need to understand what predators are actually present in your area. Predator pressure varies widely from one region to another, and even from one farm to the next. A farm on the edge of a town with a busy road nearby will have different predator problems than a farm in deep rural country with miles of open pasture and woodland. The most common predator threat to alpacas is domestic dogs. Dogs that are allowed to roam, or that escape from neighboring properties, can attack alpacas. A single dog can do serious damage to an adult alpaca, and a pack of dogs can kill multiple animals in a short time. Because dogs are often familiar with humans and human structures, they are less easily deterred by a simple fence than wild predators. A dog that is determined to get through a fence may dig under it, push through a weak spot, or climb over a low section. Coyotes are the second major predator threat. Coyotes are intelligent, persistent, and capable of digging, jumping, and climbing. They are also opportunistic. A coyote will test a fence line repeatedly, looking for a weak point. They are most active at dawn and dusk, but they will hunt at any time of day if they are hungry and the opportunity presents itself. Coyotes are especially dangerous to crias and to alpacas that are giving birth. Foxes are less of a threat to adult alpacas, but they will take crias if they can get into the pasture. Foxes are smaller than coyotes and can squeeze through surprisingly small gaps in a fence. A fence that keeps out a coyote will usually keep out a fox, but you need to pay attention to the bottom of the fence and to any gaps around gates. In some regions, bears and mountain lions are a concern. These large predators can easily break through most standard livestock fences. If you are in an area with large predators, you need a heavy-duty fencing system that is designed for those species. This usually means a combination of high-tensile electric wire and sturdy woven wire, with posts set deeper and closer together than standard alpaca fencing. Your local extension agent can tell you what predators are common in your area. Neighboring farmers who keep alpacas, sheep, or goats are also a good source of information. They can tell you what fencing has worked for them and what predators they have actually seen on their property. ## Fence Height Requirements for Alpacas Fence height is one of the most debated topics in alpaca fencing. The minimum height that will contain an adult alpaca is about 36 inches, but this is not a safe or practical height for most situations. Alpacas can jump, especially when they are startled or when they are trying to get to another alpaca on the other side of the fence. A fence that is too low invites trouble. The recommended height for alpaca fencing is 48 inches for the main pasture fence. This height will contain almost all adult alpacas under normal conditions. It will also deter most dogs and coyotes, which are reluctant to jump a fence that is chest-high or taller. For areas with heavy predator pressure, or for perimeter fences that border woodland or open country, 60 inches is a safer choice. There is an important distinction between the height of the fence material and the total height of the fence. If you use 48-inch woven wire and attach it to posts that are set in the ground, the top of the wire will be at about 48 inches, but the bottom of the wire may be 2 to 4 inches above the ground. This reduces the effective height of the fence and creates a gap that a determined predator can dig under. To get a true 48-inch fence, you need to start the wire at ground level and have the top of the wire at 48 inches. A common mistake is to install a fence that is tall enough but leaves a gap at the bottom. This is especially common on uneven ground where the installer does not want to cut the wire to follow the contour. The result is a fence that looks good from a distance but has gaps that predators can exploit. If you cannot get the wire tight to the ground, you need to add a bottom wire or a board to close the gap. Crias and juvenile alpacas do not need a taller fence than adults. In fact, they are less likely to test a fence than adults. The fence height should be based on the adult animals in your herd and on the predator pressure in your area, not on the size of the youngest animals. Remember that snow changes the effective height of a fence. In areas with heavy snowfall, the fence can be buried or the snow can drift up against it, allowing alpacas and predators to walk over the top. If you get significant snow, you may need a taller fence or a plan to clear snow away from the fence line. ## Fencing Material Options Compared There are several fencing materials commonly used for alpacas. Each has its own strengths and weaknesses, and the right choice depends on your specific situation. The main options are woven wire, field fence, high-tensile electric wire, electrified netting, and hybrid systems that combine two or more materials. ### No-Climb Woven Wire No-climb woven wire is the gold standard for alpaca fencing. This type of fence has a tight mesh pattern with openings of 2 by 4 inches or smaller. The wire is woven, not welded, which makes it more flexible and less likely to break under pressure. The small openings prevent predators from squeezing through, and the tight weave prevents alpacas from getting their heads or legs caught. The main advantage of no-climb woven wire is its predator deterrence. A coyote or dog cannot get through the small openings, and the fence is too tall for most predators to jump. The fence is also highly visible to alpacas, which reduces stress and prevents them from running into it. The main disadvantage is cost. No-climb woven wire is more expensive than standard field fence, and it requires more posts because it needs to be stretched tightly. Installation is also more labor-intensive. However, many alpaca owners consider the extra cost to be worth the peace of mind that comes with a fence that will reliably keep predators out. When choosing no-climb woven wire, look for a product with a galvanized coating that resists rust. The gauge of the wire matters too. Heavier gauge wire is stronger and lasts longer but is more difficult to work with. A 12.5-gauge wire is a good middle ground for most alpaca fencing applications. ### Standard Field Fence Standard field fence, also known as 4-point fence or hinged-joint fence, is a common choice for [livestock fencing](/knowledge/animal-farming/farm-management/livestock-fencing-systems-types-costs-installation). It has larger openings than no-climb woven wire, typically 4 by 4 inches at the bottom and 4 by 6 inches or larger at the top. The wire is less tightly woven and has more flexibility. Field fence is cheaper than no-climb woven wire and is easier to install. It is adequate for containing alpacas in most situations. However, it is less effective at keeping predators out. A determined coyote or dog can push through the larger openings, and a small predator like a fox can squeeze through easily. If you choose field fence, you should add a strand of electric wire along the top and another along the bottom to improve predator deterrence. The electric wire will discourage predators from pushing against the fence or digging underneath it. This hybrid approach can be effective, but it requires more maintenance than a solid woven-wire fence. ### High-Tensile Electric Wire High-tensile electric wire uses smooth or slightly twisted wire that is stretched tightly between posts. The wire carries an electric charge that delivers a painful but non-lethal shock to any animal that touches it. This type of fence is commonly used for cattle and horses, but it can work for alpacas if it is designed correctly. The advantage of electric wire is that it provides a strong psychological deterrent. A predator that touches the fence once will be reluctant to try again. The fence is also relatively inexpensive and easy to install compared to woven wire. The disadvantage is that electric wire does not physically contain an alpaca. If the power goes out, or if vegetation shorts out the fence, an alpaca can walk right through it. Alpacas are not as motivated to push through fences as cattle or horses, but a frightened alpaca will run through a fence without thinking. Electric wire alone is not recommended as the primary fence for alpacas, especially in areas with predator pressure. If you use electric wire, it should be part of a hybrid system with woven wire or field fence. The electric wire adds a deterrent layer on top of the physical barrier. You also need to maintain the fence carefully, keeping vegetation away from the wires and checking the charge regularly. ### Electrified Netting Electrified netting is a portable fencing system that combines plastic netting with electric wires. The netting is lightweight and can be moved easily, which makes it popular for rotational grazing and for temporary enclosures. Electrified netting can work for alpacas in temporary situations, such as a small pen for a sick animal or a temporary paddock for grazing management. It is not suitable as a permanent perimeter fence. The netting is not strong enough to stop a determined predator, and it can sag or collapse under the weight of snow or heavy vegetation. If you use electrified netting, you need to check it daily. The netting can be knocked down by animals or blown over by wind. A downed electric net is no barrier at all. Most alpaca owners use electrified netting only for short-term situations and rely on a permanent fence for the main pasture. ### Hybrid Systems Hybrid fencing systems combine two or more materials to get the benefits of each. The most common hybrid system for alpacas is woven wire or field fence with one or two strands of electric wire on top. The physical fence provides containment and a visual barrier, while the electric wire deters predators from climbing over and deters alpacas from testing the fence. Another hybrid approach is to use woven wire for the bottom 36 to 48 inches and electric wire for the top 12 to 24 inches. This gives you a total fence height of 48 to 60 inches without the cost of a full 60-inch woven wire panel. The electric wire on top is the main predator deterrent, while the woven wire provides the physical barrier. A third hybrid option is to add a strand of electric wire along the bottom of a woven wire or field fence. This deters predators from digging under the fence. The electric wire should be placed 4 to 6 inches above the ground, just above the bottom of the fence. Hybrid systems are often the most cost-effective way to get good predator protection. They allow you to use less expensive fence material for the main barrier and add electric deterrence where it is most needed. ## Posts and Hardware The fence material is only part of the system. The posts, braces, and hardware that hold the fence up are just as important. A fence is only as strong as its weakest post. ### Post Materials The three main post materials are wood, steel, and fiberglass. Each has its own advantages and disadvantages. Wooden posts are the traditional choice for livestock fencing. They are strong, durable, and attractive. The best wood posts are made from rot-resistant species like cedar, locust, or treated pine. Wooden posts need to be set in concrete or tamped tightly into the ground. They are more labor-intensive to install than steel posts, but they last for decades if they are installed correctly. Steel T-posts are the most common choice for woven wire and field fence. They are inexpensive, easy to install, and very strong. T-posts can be driven into the ground with a post driver, which makes installation fast. The main disadvantage is that T-posts are not as attractive as wooden posts, and they can bend if they are hit by heavy equipment. Fiberglass posts are a newer option. They are lightweight, rot-proof, and do not conduct electricity, which makes them a good choice for electric fence systems. Fiberglass posts are more expensive than steel T-posts but are easier to handle. They are not as strong as steel or wood, so they need to be spaced closer together. ### Post Spacing Post spacing depends on the fence material and the terrain. For woven wire and field fence, posts should be spaced 8 to 12 feet apart. Closer spacing is needed on uneven ground and in areas with heavy predator pressure. For high-tensile electric wire, posts can be spaced 20 to 30 feet apart, with line posts in between. Corner posts and gate posts need to be heavier and set deeper than line posts. These posts carry the tension of the fence and need to be braced properly. A corner post should be at least 6 inches in diameter for wood, or a heavy-duty steel post. It should be set at least 36 inches deep in the ground. Corner posts need diagonal bracing to keep them from leaning under the tension of the fence. ### Tensioning the Fence Woven wire and field fence must be stretched tightly to work properly. A loose fence sags, which creates gaps at the bottom and makes it easier for predators to push through. The fence should be stretched with a come-along or a fence stretcher, and then attached to the posts with fence staples or wire clips. The amount of tension depends on the type of fence and the temperature. Fence wire expands in heat and contracts in cold. A fence that is stretched too tight in summer will become over-tightened in winter and may pull loose from the posts. A fence that is left loose in winter will sag in summer. A good rule of thumb is to tension the fence so that it is firm but has a slight give when you push on it. You should be able to push the fence in by about 2 to 3 inches between posts. If the fence is so tight that it will not move at all, it is over-tightened. ## Step-by-Step Fence Installation Installing a permanent fence is a significant project. The following steps will guide you through the process, but you should always follow the manufacturer instructions for your specific fence materials. ### Step 1: Plan the Fence Line Walk the perimeter of the pasture and mark the fence line. Use flags or stakes to mark where the posts will go. Consider the following factors: - **Terrain:** The fence should follow the contour of the land as closely as possible. Avoid sharp turns and steep slopes where possible. - **Drainage:** Avoid placing the fence in low spots that collect water. Wet ground can undermine posts and cause the fence to sag. - **Trees:** Remove trees and large branches that could fall on the fence. Do not attach the fence to trees, as the tree will move and damage the fence. - **Gates:** Plan the location of gates so they are convenient for you and your animals. Gates should be placed in corners or at natural entry points. ### Step 2: Clear the Fence Line Clear vegetation along the fence line. You need a strip about 4 to 6 feet wide for installation. Remove brush, rocks, and debris. If you are installing an electric fence, you need to keep the vegetation clear for the life of the fence, so plan for ongoing maintenance. ### Step 3: Install Corner Posts and Braces Install the corner posts first. These are the most important posts in the fence. Set them at least 36 inches deep and brace them properly. The brace should be a diagonal post that runs from the top of the corner post to a stake in the ground at a 45-degree angle. This brace carries the tension of the fence and keeps the corner post from leaning. ### Step 4: Install Line Posts Install the line posts between the corner posts. Space them 8 to 12 feet apart for woven wire or field fence. Use a string line to make sure the posts are straight. Drive steel T-posts with a post driver or set wooden posts in holes. ### Step 5: Attach the Fence Material Start at one corner and unroll the fence material along the fence line. Attach the fence to the corner post first, then stretch it to the next corner. Use a fence stretcher to pull the fence tight, then attach it to the line posts. For woven wire and field fence, attach the fence to the posts with fence staples or wire clips. The staples should be driven in at an angle so they do not pull out easily. On T-posts, use the clips that come with the posts. ### Step 6: Secure the Bottom of the Fence The bottom of the fence must be close to the ground. On level ground, the bottom wire should be within 1 to 2 inches of the soil. On uneven ground, you may need to adjust the fence or add a bottom wire. If you are worried about predators digging under the fence, you can bury the bottom of the fence 6 to 12 inches deep. This is called trenching the fence. It is labor-intensive but provides excellent predator protection. You can also lay the bottom of the fence flat on the ground and cover it with rocks or landscape staples. ### Step 7: Install Electric Wires If you are adding electric wires to your fence, install them after the main fence is in place. Use insulators on wooden posts or the built-in insulators on T-posts. The wire should be attached to a charger that is properly grounded. The electric wire should be placed 4 to 6 inches above the bottom of the fence for predator deterrence, and 6 to 12 inches above the top of the fence for climbing deterrence. Test the fence with a voltage meter to make sure it is working properly. ### Step 8: Install Gates Install gates at the entry points you planned in Step 1. Use sturdy metal gates that are at least 48 inches tall. The gate should swing freely and close securely. The latch should be easy for you to operate but difficult for an alpaca to open. Check the gap under the gate. If there is a gap of more than 2 inches, you need to add a bottom board or wire to close it. Predators will dig under gates just as readily as they will dig under the fence. ## Common Fencing Mistakes Even experienced farmers make mistakes when installing alpaca fencing. The following are the most common problems and how to avoid them. ### Mistake 1: Using a Fence That Is Too Low A 36-inch fence might contain alpacas in a calm situation, but it will not stop a frightened alpaca from jumping, and it will not deter a determined coyote. The minimum height for alpaca fencing is 48 inches, and 60 inches is better in high-pressure areas. ### Mistake 2: Leaving Gaps at the Bottom A fence that is 48 inches tall but has a 6-inch gap at the bottom is not a 48-inch fence. The effective height is only 42 inches, and the gap is an invitation to predators. The bottom of the fence must be tight to the ground. ### Mistake 3: Using Field Fence Where Predator Pressure Is High Field fence is cheaper than no-climb woven wire for a reason. The larger openings allow predators to push through. If you have coyotes, dogs, or foxes in your area, spend the extra money on no-climb woven wire. ### Mistake 4: Forgetting to Brace Corner Posts Corner posts carry the tension of the entire fence. If they are not braced properly, they will lean over time, and the fence will sag. Corner posts need diagonal bracing and should be set deeper than line posts. ### Mistake 5: Not Maintaining the Electric Fence An electric fence that is not working is just a fence. Vegetation growing against the wires will short out the charge. The charger battery can die. Wires can break. You need to check the fence regularly and keep the charge at the recommended level. ### Mistake 6: Ignoring the Gates Gates are the weakest point in most fencing systems. A gate that does not close properly, a latch that is easy to open, or a gap under the gate all create opportunities for predators. Choose high-quality gates and maintain them. ### Mistake 7: Installing the Fence without Checking Local Regulations Some areas have regulations about fence height, materials, and placement. Check with your local planning department or extension office before you install a fence. This is especially important if you are on a property line, where you may need to coordinate with your neighbor. ## Decision Thresholds: Which Fence Should You Choose? With so many options available, it can be difficult to decide which fencing system is right for you. The following decision framework will help you narrow down your options. ### Choose No-Climb Woven Wire If: - You have coyotes, dogs, or foxes in your area - You are willing to spend more upfront for better protection - You want a low-maintenance fence that will last for decades - You have uneven ground that requires a fence that follows the contour closely ### Choose Field Fence with Electric Wire If: - You have low predator pressure - You are on a tight budget - You are willing to do regular maintenance on the electric fence - You are fencing a large area and need to control costs ### Choose High-Tensile Electric Wire If: - You are fencing a very large area - You have low predator pressure - You are willing to check the fence daily - You have a backup plan for power outages ### Choose Electrified Netting If: - You need a temporary enclosure - You are rotating grazing areas - You have no predator pressure - You will be present to monitor the fence ### Choose a Hybrid System If: - You want the best predator protection at a reasonable cost - You have moderate predator pressure - You are willing to maintain electric fence components - You want the flexibility to adjust the level of deterrence ## Monitoring and Recordkeeping A fence is not a set-and-forget system. It requires regular monitoring and maintenance to stay effective. The following practices will help you keep your fence in good working order. ### Monthly Fence Inspections Walk the entire fence line at least once a month. Look for the following: - **Sagging sections:** Push on the fence to check tension. Re-tension any loose sections. - **Rust and corrosion:** Check for rust on the wire and on the posts. Replace any badly corroded sections. - **Holes and gaps:** Look for holes at the bottom of the fence and gaps around gates. - **Vegetation:** Clear any vegetation that is touching the fence, especially around electric wires. - **Post stability:** Push on each post to check that it is still firmly set in the ground. - **Gate operation:** Open and close each gate to check that it operates smoothly and latches securely. ### After-Storm Inspections Inspect the fence after every major storm. High winds can blow trees onto the fence, heavy rain can wash out posts, and snow can bury the fence. Check for damage and make repairs promptly. ### Electric Fence Checks If you have electric fence components, check them weekly. Use a voltage meter to test the charge at the farthest point from the charger. The charge should be at least 3,000 volts for alpacas and predators. Clear any vegetation that is touching the wires. Check the charger and the grounding system. ### Recordkeeping Keep a simple log of fence inspections and repairs. Record the date of each inspection, any problems you found, and the repairs you made. This log will help you identify recurring problems and plan for future maintenance. A simple spreadsheet or notebook is sufficient. The log does not need to be elaborate, but it should be consistent. If you notice that a particular section of fence needs repair every few months, you may need to replace that section entirely. ## When to Call a Veterinarian or Extension Agent Most fence problems are not emergencies, but there are situations where you should seek professional help. ### Call a Veterinarian If: - An alpaca has been injured by the fence. Cuts, punctures, and leg injuries from fence wire can be serious. A veterinarian should examine any alpaca that has been caught in or cut by a fence. - An alpaca has been attacked by a predator. Even if the injuries look minor, a veterinarian should examine the animal. Predator attacks can cause internal injuries that are not visible from the outside. - You notice alpacas chewing on the fence or licking the posts. This can be a sign of a nutritional deficiency, and a veterinarian can help you diagnose and treat the problem. ### Call an Extension Agent If: - You are unsure what predators are in your area. Your extension agent can tell you what species are common and what fencing is recommended for your region. - You are planning a new fence and want advice on materials and design. Extension agents have access to research-based information on livestock fencing. - You are having problems with a fence that you cannot diagnose. An extension agent can help you identify the cause of sagging, rust, or other problems. - You have questions about local regulations or cost-share programs for fencing. Your veterinarian and extension agent are resources that can save you time and money. Do not hesitate to call them when you have questions or concerns. ## Frequently Asked Questions ### What is the best fence height for alpacas? The recommended height for alpaca fencing is 48 inches for the main pasture fence. This height will contain adult alpacas and deter most dogs and coyotes. In areas with heavy predator pressure, or for perimeter fences that border woodland or open country, 60 inches is a safer choice. Remember that the effective height of the fence is measured from the ground to the top of the fence material. A fence that has a gap at the bottom is effectively shorter than its nominal height. ### Can I use cattle panels or hog panels for alpacas? Cattle panels and hog panels are not recommended for alpacas. These panels have large openings that alpacas can get their heads or legs caught in, and the openings are large enough for predators to squeeze through. If you use these panels, you should cover them with woven wire or add electric wire to improve safety and predator deterrence. The best choice for alpacas is no-climb woven wire with openings of 2 by 4 inches or smaller. ### Do I need a top rail on my alpaca fence? A top rail is not strictly necessary, but it is a good idea in areas with predator pressure. A top rail makes the fence more visible to alpacas and predators, and it adds strength to the top of the fence. You can use a wooden rail, a metal pipe, or a strand of electric wire as a top rail. The electric wire is the most effective option because it delivers a shock to any animal that tries to climb over the fence. ### How do I keep predators from digging under my alpaca fence? The best way to keep predators from digging under the fence is to bury the bottom of the fence 6 to 12 inches deep. This is called trenching the fence. You can also lay the bottom of the fence flat on the ground and cover it with rocks or landscape staples. Adding a strand of electric wire 4 to 6 inches above the ground along the bottom of the fence is another effective deterrent. Digging predators will touch the wire and receive a shock. ### Is electric fencing safe for alpacas? Electric fencing is safe for alpacas when it is installed and maintained correctly. The shock from an electric fence is painful but not harmful. Alpacas learn quickly to avoid the fence. The main risk is that an alpaca will run through an electric fence when it is frightened, so electric fencing should not be used as the only barrier. Use electric wire as a supplement to a physical fence, not as a replacement. ### How many strands of electric wire do I need? For predator deterrence, you need at least one strand of electric wire at the top of the fence and one strand at the bottom. The top strand should be 6 to 12 inches above the top of the physical fence, and the bottom strand should be 4 to 6 inches above the ground. In areas with heavy predator pressure, you may want to add a third strand in the middle. The exact placement depends on the height of your fence and the predators in your area. ### How far apart should fence posts be for alpacas? For woven wire and field fence, posts should be spaced 8 to 12 feet apart. Closer spacing is needed on uneven ground and in areas with heavy predator pressure. For high-tensile electric wire, posts can be spaced 20 to 30 feet apart, with line posts in between. Corner posts and gate posts should be heavier and set deeper than line posts, and they need diagonal bracing. ### How often should I check my alpaca fence? You should walk the entire fence line at least once a month and after every major storm. Check for sagging, rust, holes, and vegetation touching the fence. If you have electric fence components, check them weekly with a voltage meter. The charge should be at least 3,000 volts. Keep a log of your inspections and repairs so you can identify recurring problems. ## Related Farming Guides This section will be populated programmatically with links to related guides on alpaca care, pasture management, predator deterrence, and other livestock fencing topics.
