6 Best Walk-In Corral Netting for Fly Control

There’s nothing more frustrating than watching your cattle stamp, swish, and bunch up in a corner, tormented by a black cloud of flies. It’s not just an annoyance; that stress hits them right in the gut, affecting weight gain and overall health. A good walk-in fly corral isn’t a luxury, it’s a fundamental tool for giving your animals a place of refuge during the worst of the fly season.

Key Features in Walk-In Fly Corral Netting

The first thing to understand is that not all netting is created equal. The goal is a physical barrier that keeps flies out but lets air in, and striking that balance is everything. You’re looking for a solution that can withstand a rubbing cow, a summer gale, and the relentless sun.

The material and its weave are the heart of the system. Look for high-density polyethylene (HDPE) with UV inhibitors woven in, not just coated on. A coated product will lose its sun protection in a few seasons. The mesh size is also critical; you need a weave tight enough to block horn flies and face flies but open enough to prevent the corral from turning into a sauna.

Beyond the fabric, consider the whole structure. How does it attach to your panels? Reinforced seams and brass or stainless steel grommets are non-negotiable. A cheap system will have grommets that rip out in the first high wind. Also, pay close attention to the entrance design. Simple slits are okay, but overlapping, weighted vinyl strips provide a much better seal after a cow walks through.

Agri-Mesh ProGuard Netting for Peak Fly Season

When fly pressure is at its absolute peak, Agri-Mesh ProGuard is the specialist’s choice. Its claim to fame is an exceptionally fine mesh, designed to stop even the smallest biting gnats and stable flies that can sometimes slip through standard netting. This is the stuff you turn to when the flies are so bad the cattle won’t even leave the barn.

The primary tradeoff for that superior protection is airflow. On a dead-still, 95-degree day, a corral wrapped in ProGuard can feel a bit stuffy. You have to weigh that against the relief it provides from relentless biting flies. For most situations, especially where there’s a decent breeze, the cattle will happily trade a little airflow for a fly-free hideout.

This isn’t flimsy window screening. ProGuard is built with a high tear strength and robust, reinforced edging that holds up to abuse. It’s an investment, for sure, but it’s designed to last multiple seasons, not just one. Think of it as the heavy-duty option for farms with a documented history of severe fly problems.

Tarter Farm & Ranch Fly Stop Corral Panel Kit

Tarter’s approach is all about integration and convenience. Instead of selling you a bulk roll of netting and a bag of hardware, their Fly Stop system is a kit. It comes with pre-sized netting panels specifically designed to fit their popular corral panels. This takes all the measuring, cutting, and guesswork out of the equation.

If you already have a Tarter setup, or are planning a new one, this is easily the most seamless option. The included clips and fasteners are made to work with their panels, ensuring a snug, secure fit with no awkward gaps. For a hobby farmer short on time, this plug-and-play approach can be a huge advantage. You can realistically get a small corral fully netted in an afternoon.

The only real downside is that you’re buying into a specific ecosystem. If your corral is a motley collection of gates and panels from three different manufacturers (and let’s be honest, many of ours are), this kit won’t work without significant modification. It’s a perfect solution for a standardized setup but less flexible for a custom or inherited one.

Behlen Country Dura-Weave for High-Wind Areas

If your farm is on an exposed ridge or in a wide-open prairie, wind is your number one enemy for any netting system. A standard fly screen can act like a giant sail, putting immense strain on your corral panels and the netting itself. Behlen Country specifically designed their Dura-Weave to tackle this exact problem.

The magic is in the weave. It’s a bit more open than some of the ultra-fine meshes, which allows a significant amount of wind to pass directly through it. This dramatically reduces the "sail effect" and the stress on the entire structure. While it might let the absolute tiniest no-see-ums through on a calm day, it provides excellent protection against the main culprits—horn, face, and stable flies—while ensuring your corral is still standing after a thunderstorm.

Behlen pairs this wind-permeable design with seriously tough construction. The material has a high tensile strength, and the reinforced borders are meant to handle the constant flexing and flapping that wind causes. This is the netting you choose when durability against the elements is your top priority. It’s built for longevity in harsh, open-range conditions.

PasturePro Heavy-Duty Barrier for Large Herds

For those with a larger herd or a bigger corral system, buying pre-sized kits can be impractical and expensive. PasturePro’s Heavy-Duty Barrier is the go-to for custom, large-scale applications. It typically comes in large bulk rolls, allowing you to cover extensive fence lines efficiently.

This product is all about raw material specs. It boasts a very high tear strength and is heavily treated with UV inhibitors for a long life in direct sun. The idea is that you’re buying a professional-grade barrier material that you can adapt to your specific needs, whether that’s a 100-foot-long holding pen or a complex alleyway system.

Be prepared for a more involved installation. This is not a simple kit. You’ll be the one responsible for ensuring it’s properly tensioned, which often means running a top support wire and using a lot of high-quality fasteners. It’s more work upfront, but it results in a truly custom, robust system that can provide a huge sanctuary for a larger number of animals.

Farm-Tek ClearVu Ventilated Netting System

A common complaint with dark-colored fly netting is that it can make a corral feel dark and enclosed, almost like a cave. Farm-Tek’s ClearVu system addresses this by using a lighter-colored, translucent material. This improves visibility, making it much easier to check on your animals, and brightens the interior, which can make cattle less hesitant to enter.

The primary benefit, however, is superior ventilation. The unique weave is engineered to maximize airflow while still presenting a formidable barrier to flies. In hot and humid climates where heat stress is a major concern, this can be a game-changer. The increased air movement helps keep the animals cooler and more comfortable.

This focus on airflow and light makes it an excellent choice for calf creeps or pens where you need to keep a close eye on younger, more vulnerable animals. The tradeoff is that it may not block quite as much solar radiation as a dark, heavy shade cloth, but its ability to reduce heat buildup through ventilation often more than compensates for this. It’s about creating a bright, airy, and comfortable refuge.

Hutchison Western Stock-Guard for Easy Setup

Sometimes, the best tool is the one that’s easiest to use. Hutchison Western’s Stock-Guard netting is designed with the time-crunched farmer in mind. It’s known for being lightweight, manageable, and incredibly straightforward to install, making it a favorite for those who need a reliable solution without a major project.

The key to its simplicity is in the details. The netting often comes in standard heights that match common corral panels (e.g., 5 or 6 feet) and is loaded with grommets, usually spaced every 12 to 18 inches. This abundance of attachment points makes it easy to get a tight, sag-free fit using simple zip ties or bungee cords, without needing special hardware.

While it may not have the extreme wind-resistance of Behlen or the ultra-fine mesh of Agri-Mesh, it provides excellent, all-around fly protection for most farm situations. It’s a durable, no-nonsense product that delivers on its promise. For a small herd in a moderately sheltered location, this is often the most practical and efficient choice.

Proper Installation for Maximum Fly Reduction

You can buy the best, most expensive netting on the market, but it won’t do a bit of good if it’s installed poorly. Flies are experts at finding the smallest gap, so your goal is to create a completely sealed-off space. A sloppy installation is just an invitation for them to come in and get trapped with your cattle.

Pay special attention to the bottom edge. A gap between the netting and the ground is the most common entry point for crawling flies. The best practice is to leave an extra 6-8 inches of material at the bottom and weigh it down with sandbags, or better yet, fasten it to a ground-level lumber skirt. Likewise, ensure you use every grommet. Skipping attachment points creates sags that turn into fly highways during a breeze.

The entrance is your system’s weakest link. A simple slit cut in the netting is better than nothing, but it’s not ideal. A walk-through made of heavy, overlapping vinyl or shade cloth strips provides a much better seal. For a top-tier setup, creating a small, two-door "fly trap" entrance can reduce fly entry by over 90%. The extra effort in sealing the perimeter and fortifying the entrance is what separates a decent fly corral from a great one.

Ultimately, the best walk-in corral netting is the one that fits your climate, your herd size, and your tolerance for wind. Choosing the right material and installing it with care gives your cattle a true sanctuary from the stress of fly season. That quiet, peaceful corral is one of the most satisfying sights on a hot summer afternoon.
