6 Best Feeder Varmint Cages for Farm Feeders
Protect your feed and save money with time-tested varmint cages. Discover 6 durable, farmer-approved designs for small farm feeders that keep pests out.
You fill the feeder on Sunday, expecting it to last the week, but by Tuesday morning it’s picked clean and the ground is littered with half-eaten corn. This isn’t just frustrating; it’s a direct hit to your wallet and a risk to your animals’ health from contaminated feed. Protecting that feed is one of the small, constant battles that defines life on a small farm, and winning it requires the right tools.

Protecting Your Feed From Persistent Varmints
Varmints are more than just a nuisance. Raccoons, squirrels, and opossums are intelligent, incredibly persistent, and surprisingly strong. They don’t just steal food; they chew through plastic barrels, break spinner mechanisms, and contaminate what’s left behind with droppings, which can spread disease to your livestock or game.
The goal of a feeder cage isn’t just to create a barrier. It’s to create a selective one. The design must allow your target animals—be it deer, poultry, or goats—to access the feed while physically blocking the paws and mouths of pests. This is a game of inches, where the size of the wire mesh and the strength of the welds make all the difference.
When you’re choosing a cage, you’re balancing three things: the type of feeder you have, the specific varmint you’re fighting, and the durability of the cage itself. A flimsy wire cage might deter a casual squirrel, but a determined raccoon will peel it open like a tin can. Investing in the right protection from the start saves you from replacing feed and feeders down the road.
Rugged Ranch Universal Cage: Versatile Choice
The biggest headache with feeder cages is often finding one that actually fits your specific feeder barrel or tripod. The Rugged Ranch Universal Cage solves this by being designed for adaptability. It’s built to clamp onto the outside of most standard 55-gallon or 30-gallon feeder barrels, making it a go-to choice if you’re not sure of your feeder’s exact brand or model.
This cage is typically made from heavy-gauge steel wire with a powder-coated finish to stand up to the weather. The key is the grid pattern, which is usually around 2×2 inches. This is large enough for corn or protein pellets to be slung out by the spinner mechanism but small enough to block a raccoon’s paws from reaching the spinner plate, which is their primary target.
Installation is straightforward, usually involving a few bolts to clamp the cage sections together around the barrel. While it’s called "universal," you might occasionally need a heavy-duty zip tie to snug it up perfectly on an odd-sized barrel. It’s the best all-around option for the most common type of farm feeder.
Tarter Heavy-Duty Guard for Raccoon Defense
If your main problem is raccoons, you need to bring out the heavy artillery. Tarter is a brand known for tough, no-nonsense farm equipment like gates and stock tanks, and their feeder guards are built with that same philosophy. These aren’t just wire mesh; they’re closer to a small fortress for your feeder.
The Tarter guard is constructed from thick, welded steel rods, not wire. This is critical because a determined raccoon can break weak welds or bend thin wire over time. The spacing is specifically engineered to defeat a raccoon’s impressive reach and dexterity, preventing them from manipulating or damaging the spinner.
This level of protection is overkill if you’re only dealing with squirrels. But if you’ve ever come out to find your feeder’s motor torn apart and the barrel emptied by a family of raccoons, you understand the value. Think of it as an investment; you buy it once and solve your raccoon problem for good.
Squirrel Buster Plus: Integrated Cage Feeder
Keep squirrels away from birdseed with the Squirrel Buster Plus. Weight-activated ports close when squirrels try to feed, while providing ample perching space and six feeding ports for small birds.
Sometimes the solution isn’t an add-on cage but a feeder designed from the ground up to be pest-proof. The Squirrel Buster Plus is a classic example, though it’s primarily for birdseed, not bulk livestock feed. It’s an essential tool for protecting high-cost seed for songbirds around the farmhouse or barn.
Its genius lies in its weight-activated mechanism. The outer "cage" is part of a shroud that surrounds the seed tube. When a lightweight songbird lands on a perch, nothing happens. But when a heavier squirrel, grackle, or pigeon lands on it, their weight pulls the shroud down, closing off all access to the feeding ports.
This is a specialized tool, not a universal farm solution. You can’t put corn or large pellets in it, and it’s not meant for deer or goats. But for keeping your expensive black oil sunflower seed safe for the birds you actually want to feed, it’s an incredibly effective, set-it-and-forget-it system.
Yard Gard Hardware Cloth for Custom DIY Cages
Sometimes the perfect cage is the one you build yourself, especially for custom-built or oddly shaped feeders. For this, nothing beats good old-fashioned hardware cloth. It’s affordable, widely available, and gives you complete control over the final product.
The key is to choose the right specifications. For most applications, a 1/2-inch by 1/2-inch mesh is the sweet spot—it stops virtually all pests, including small squirrels and rats. Pay close attention to the gauge of the wire; a lower number means a thicker, stronger wire. A 19-gauge wire is a good minimum, but 16-gauge is even better for raccoon country.
Building your own cage requires a good pair of wire snips, heavy gloves, and something to fasten it with, like J-clips or heavy-duty steel zip ties. It takes time and effort, but it’s the most cost-effective way to protect a unique feeder. Your cage will only be as strong as your craftsmanship, so take the time to make clean cuts and secure all connections tightly.
Miller Manufacturing Galvanized Varmint Guard
Not all protection needs to be a full cage. For hanging feeders, like those often used for poultry inside a coop or a covered run, the Miller Manufacturing Varmint Guard is a simple and highly effective deterrent. It’s less of a cage and more of a baffle, designed to block access from above and below.
This 6-pack of Tiflev Goat Feeders simplifies livestock care by combining feeding and watering. The 3.5-quart capacity minimizes refills, while the mess-free design reduces waste and keeps your coop clean.
Typically shaped like a wide cone or a square, this guard is made of galvanized steel for excellent rust resistance in humid environments. You install it on the chain or rope above the feeder. A squirrel or rat attempting to climb down from a rafter will be met with a slick, wide surface they can’t get around.
This guard works best when the feeder is hung away from walls or posts that pests could use to jump sideways, bypassing the baffle. It’s not meant to stop a pest that can reach the feeder from the ground. But for its intended purpose—protecting a hanging feeder from climbing pests—it’s a durable, affordable, and classic solution.
Behlen Country Large Pen for Ground Feeders
Protecting ground troughs or broadcast feed for animals like deer, sheep, or goats presents a different challenge. A small cage won’t work. The solution is to scale up, creating a large "cage" or exclusion pen using livestock panels, and Behlen Country is a top name in this space.
The strategy is to build a circular or square pen around the feeding area using multiple heavy-duty utility or hog panels. The effectiveness depends on the panel’s grid spacing. You can configure it in two ways:
- Keep big pests out: Use panels with openings large enough for a deer to stick its head through to eat but too small for a wild hog or a cow to get in.
- Let small animals in: Use panels with larger openings at the bottom, allowing fawns or smaller goats to slip inside the pen to eat undisturbed by larger, more dominant animals.
This is a significant project, requiring T-posts and a post driver, and it’s a real investment in materials. However, if you’re putting out hundreds of pounds of feed on the ground, it’s the only practical way to ensure it’s eaten by the intended animals. It protects a large feeding zone rather than just a single feeder.
Proper Cage Installation and Placement Tips
A top-of-the-line cage is worthless if it’s installed improperly. Varmints are experts at finding and exploiting the slightest weakness, so a secure installation is just as important as the cage itself. A loose fit or a small gap is an open invitation.
Take the time to do it right. A few extra minutes with a wrench or a pair of pliers can make the difference between a protected feeder and a ransacked one. Pay attention to the details, because you can be sure the raccoons will.
- Eliminate Gaps: Ensure the cage sits flush against the feeder body. Use bolts, screws, or heavy-duty steel zip ties to secure it tightly. A raccoon can get a surprising amount of leverage with its paws in even a half-inch gap.
- Check the Spinner Zone: Make sure the bottom of the cage provides enough clearance for your spinner to throw feed effectively. A cage that’s too low will block the feed, causing it to pile up and clog the motor.
- Think Three-Dimensionally: Don’t just protect the feeder itself. Place the feeder away from overhanging tree limbs, fences, or anything a squirrel can use as a launchpad to jump directly onto the feeder, bypassing your cage entirely.
- Stabilize Tripods: For tripod feeders, consider staking down the legs. A big raccoon or a small hog can rock a feeder back and forth to shake loose extra corn, and a strong one can even knock it over.
Ultimately, choosing the right varmint cage comes down to knowing your enemy and your equipment. There’s no single magic bullet, but by matching the cage’s design to the pest you’re fighting—from a heavy-duty Tarter for raccoons to a DIY hardware cloth cage for a custom trough—you can protect your feed, save money, and win one of the most persistent battles on the farm.
