6 Best Wool Netting for Predator Protection

You walk out to the pasture at dawn and your heart sinks. The telltale signs of a predator visit are everywhere, and you’ve lost one of your best ewes. It’s a gut-wrenching experience that makes you question if keeping a small flock is even worth the heartache. Before you invest in complex alarms or high-tensile fencing, it’s worth looking at a solution that has protected flocks for generations: wool netting.

Why Wool Netting Deters Cunning Predators

A predator’s greatest weapon is its intelligence, especially with canids like foxes and coyotes. They test fences, looking for weaknesses. Wool netting works because it plays on their psychology, not just their ability to push through a barrier. The secret is the strong, lingering scent of lanolin from unwashed wool.

To a coyote, the concentrated smell of a wool fence doesn’t just register as "sheep." It registers as a massive number of sheep, far more than are actually present. This creates confusion and hesitation. A predator sizing up a flock wants an easy meal, not a confrontation with what smells like an overwhelming force.

This scent-based deterrent is what makes wool netting fundamentally different from standard electric or wire fencing. It’s a biological "no-go" signal. Instead of presenting a simple physical challenge to be overcome, it suggests the risk isn’t worth the reward. It turns your pasture’s perimeter into a psychological barrier.

Shepherd’s Sentry: The Classic Lanolin Scent

Shepherd’s Sentry is the old-school standard, and for good reason. It’s essentially a simple, woven net made from coarse, minimally processed wool, leaving as much of the potent lanolin intact as possible. There are no bells and whistles here. Its effectiveness comes purely from its powerful, sheep-heavy aroma.

This type of netting is best for reinforcing existing pastures or for creating temporary paddocks where predator pressure is moderate. Think of it as your first line of defense against curious foxes or the occasional opportunistic coyote. It’s relatively lightweight and easy to move, making it a solid choice for rotational grazing systems.

The main tradeoff is its reliance on scent alone. In areas with highly habituated or desperate predators, the scent may not be enough to deter a determined attack. It also requires a bit of maintenance; the scent fades with heavy rain and sun, so some old-timers will "recharge" it by rubbing raw fleece along the top line once a season.

Gallagher WoolGuard: Electric-Ready Predator Net

Sometimes, you need to combine old wisdom with a modern jolt. Gallagher WoolGuard (or similar electric-ready types) does just that by weaving conductive poly-wire filaments directly into the wool strands. This gives you a powerful two-for-one deterrent: the confusing scent of wool and the unforgettable zap of an electric fence.

This is the setup for hobby farmers dealing with persistent predator problems. A bold coyote that pushes past the scent barrier will get a sharp shock, teaching it a lesson that a simple scent can’t. It’s incredibly effective for protecting lambing pens or smaller, high-value pastures where losses are simply not an option.

Of course, this system requires more setup. You’ll need a fence charger, a good ground rod, and the discipline to keep the fence line clear of weeds that can short it out. It’s more work and a bigger initial investment, but the peace of mind is often worth it. It’s the best choice when you need to be absolutely certain your flock is secure.

High-Country Woven Wool for Tough Terrains

Not all pastures are flat, manicured fields. Many of us are working with rocky hillsides, uneven woods, and creek beds. This is where a High-Country Woven Wool net shines. Its design prioritizes durability and flexibility over maximum scent.

These nets feature a tighter, denser weave using a stronger grade of wool. This construction allows the netting to drape over uneven ground without creating the dangerous gaps that a stiffer net would leave. A coyote can’t exploit a low spot under the fence if the fence itself is contoured to the ground.

While the lanolin scent is still present, it’s a secondary feature. The primary benefit is its physical integrity on challenging landscapes. If your biggest fencing challenge is the terrain itself, this is the style to look for. It ensures your barrier remains a barrier, no matter how rough the ground beneath it.

Coyote Thwart Wool Barrier for Varmint Control

This is a specialty product for a specific problem: smart, determined coyotes. Coyote Thwart barriers are designed for maximum psychological impact. They often use wool from more pungent breeds and are intentionally less processed to retain a "dirty flock" smell that suggests a large, established, and territorial group of sheep.

The construction is also different. These barriers are often taller than standard netting, typically 48 inches or more, to prevent jumping. The weave might be tighter at the bottom and wider at the top, concentrating the physical barrier where canids are most likely to push and test it.

This isn’t your all-purpose netting. It’s heavier, more expensive, and frankly, it smells. But if you have a known coyote pack that has become bold and is actively testing your other defenses, upgrading a key fenceline to this type of barrier can be the strategic move that finally convinces them to hunt elsewhere.

Prairie Protector Net: Wide-Area Flock Safety

When you have a few acres to protect, the cost and weight of heavy-duty netting can become impractical. The Prairie Protector style addresses this by focusing on efficient, large-scale coverage. These nets are sold in longer rolls—often 150 feet or more—and are made from a slightly lighter wool blend to keep them manageable.

The goal here is to establish a strong scent perimeter over a large area. The physical barrier is less formidable than a High-Country net, but the sheer scale of the lanolin scent signature it creates can effectively deter predators from even entering the pasture. It’s an excellent choice for perimeter fencing on multi-acre hobby farms.

The tradeoff is durability. Being lighter, it’s more susceptible to damage from livestock or wildlife like deer. It’s best used as an outer boundary, perhaps with a more robust interior fence or a livestock guardian animal providing secondary protection. It’s about creating a wide "scent wall" to make your property an unattractive target from a distance.

Old Timer’s Lanolin Line: A Traditional Choice

Sometimes you don’t need a whole new fence. You just need to make your existing fence better. The Old Timer’s Lanolin Line isn’t a net at all, but a thick, loosely spun rope of raw wool saturated with lanolin. It’s a simple, brilliant tool for augmenting what you already have.

You simply run a strand of this lanolin line along the top or middle of your existing wire, wood, or woven fence. Predators investigating the fenceline will encounter the powerful sheep scent first, often deterring them before they even test the physical barrier. It’s an incredibly cost-effective way to add a layer of psychological defense.

This is the perfect solution for the farmer on a tight budget or someone who wants to add protection without a major fencing project. Here are its best uses:

• Running a line along the outside of a chicken run to deter foxes.
• Adding a strand to field fencing to discourage coyotes from digging underneath.
• Stringing it around a garden to dissuade deer, who are also unsettled by the predator-mimicking scent of sheep.

Installing Wool Netting for Maximum Effectiveness

Putting up a wool net isn’t complicated, but a few details make all the difference. A poorly installed net is just an obstacle; a well-installed one is a true deterrent. First and foremost, the net must be taut. A sagging net creates gaps and invites predators to push through. Use quality posts and pull it tight from corner to corner.

Pay close attention to the bottom edge. This is where predators will try to dig or push under. The netting should be in constant contact with the ground. On uneven terrain, you may need to use extra ground stakes or even pull soil or rocks against the base to eliminate any gaps. A gap of just a few inches is an open invitation.

Finally, remember that the scent is a finite resource. In very hot, sunny, or rainy climates, the lanolin will degrade over the season. If you notice the scent has faded significantly, you can lightly spray it with a commercial lanolin solution or, as mentioned, rub raw fleece along the top line. Maintaining the scent is just as important as maintaining the fence’s tension.

Ultimately, protecting your flock is about creating multiple layers of defense, and wool netting is a time-tested layer that works with animal nature, not against it. It respects the intelligence of predators by using their own instincts against them. By choosing the right type for your land and your specific challenges, you’re not just buying a fence—you’re adopting a piece of agricultural wisdom that has kept sheep safe for centuries.
