If you're tired of furry thieves emptying your corn overnight, building a homemade deer feeder varmint guard is the easiest way to reclaim your hunting spot and save a literal ton of money on feed. There's honestly nothing more frustrating than trekking out to your barrel, expecting it to be half full, only to realize a family of raccoons has been treated to an all-you-can-eat buffet for the last three days. It's expensive, it's annoying, and it messes up the patterns of the deer you're actually trying to attract.
Raccoons and squirrels aren't just hungry; they're incredibly smart and surprisingly strong. They'll hang off the spinner plate, spin it manually with their paws, or even chew right through plastic components to get to the goods. Commercial guards are out there, but they can be surprisingly pricey for what is essentially a bit of bent wire. Making your own isn't just a budget move—it often results in a tougher, more customized solution that fits your specific feeder setup perfectly.
Why a DIY Guard Makes Sense
Most people start looking into a homemade deer feeder varmint guard after they see their first trail cam video of a raccoon doing gymnastics on their feeder. It's a rite of passage for anyone who maintains a property. But why go the DIY route instead of just clicking "buy" on a pre-made one?
First off, it's about the fit. Feeder motors and downspouts come in all sorts of weird shapes and sizes. A "universal" guard from a big-box store rarely fits perfectly without some annoying modifications. When you build it yourself, you can tailor the dimensions so there's enough clearance for the corn to throw properly, but not enough room for a paw to reach in.
Then there's the durability factor. A lot of the cheap plastic guards you buy online will get chewed to pieces in a single season. If you use heavy-duty hardware cloth or thick gauge wire, you're building something that's going to last for years, not just a few months. Plus, there's a certain level of satisfaction in knowing you outsmarted the critters with $10 worth of materials from the local hardware store.
Choosing the Right Materials
To get started on your homemade deer feeder varmint guard, you don't need a specialized machine shop. Most of the stuff you need is probably sitting in your garage or available for a few bucks at the nearest home improvement center.
The "gold standard" material for this project is 1/4-inch or 1/2-inch hardware cloth. It's basically a stiff wire mesh. You want the gaps small enough that a raccoon can't reach their nimble little fingers through, but large enough that it doesn't trap the corn and cause a clog.
You'll also need: * Heavy-duty wire snips or side cutters * Self-tapping screws (if you're mounting to a metal control box) * Zip ties (the heavy-duty, UV-resistant black ones) * Pliable galvanized wire for "sewing" the mesh together * A pair of work gloves (that wire mesh is sharp!)
The Classic Cage Design
The most common and effective homemade deer feeder varmint guard is the basic cage. This is essentially a wire box that surrounds the entire motor and spinner assembly.
To build this, you'll want to measure the diameter and depth of your motor box. You need to leave at least 2 to 3 inches of clearance on all sides of the spinner plate. If the cage is too tight, the corn will hit the wire and drop straight down, which defeats the purpose of having a broadcast feeder. If it's too loose, the raccoons will just lean against the wire and reach in anyway.
Cutting and Shaping
Start by cutting a long strip of hardware cloth that can wrap all the way around the motor assembly with an inch or two of overlap. Once you've got the circular shape (or square, depending on your motor), use your galvanized wire to "sew" the seam shut. Make sure there are no large gaps.
The Bottom Plate
The trickiest part is the bottom. Some guys leave it open, but if your feeder is low enough, raccoons will just reach up from the ground. It's better to cut a circular piece of mesh for the bottom and attach it to the sides. However, you need to make sure the corn can still fly out. Many hunters find that using a slightly larger mesh on the very bottom works best, or simply ensuring the side walls are tall enough that a raccoon can't reach the spinner from underneath.
The Varmint Plate Alternative
If you don't want a full cage, another popular homemade deer feeder varmint guard is the "varmint plate" or "eliminator" style. This involves mounting a secondary, larger plate or a set of "spikes" around the spinner.
Some people use a simple piece of sheet metal cut into a circle that sits just above the spinner. It acts as a shield, making it physically impossible for a raccoon sitting on the motor box to reach down and touch the plate. It's a bit more "minimalist" and doesn't interfere with the corn throw as much as a wire cage might.
Another old-school trick is the "shark tooth" method. You take a piece of light-gauge metal, cut triangular notches into it to make it look like a saw blade, and mount it around the edge of the motor box. While it sounds a bit aggressive, it usually just makes the feeder uncomfortable to hang onto, sending the raccoons looking for an easier meal elsewhere.
Don't Forget the Legs
A homemade deer feeder varmint guard is only half the battle. If they can't get to the spinner, they'll try to climb the legs. One of the best ways to supplement your guard is by installing "leg guards" or "pvc sleeves."
You can take a 4-inch diameter PVC pipe, cut it into 3-foot sections, and slide them over the legs of your feeder. Because the PVC is smooth and spins freely on the leg, the raccoons can't get a grip. They'll try to climb, the pipe will spin or they'll just slide down, and they'll eventually give up. It's a hilarious thing to watch on camera, honestly.
Another trick is using heavy-duty grease on the legs, but that's a mess to deal with when you're trying to refill the feeder yourself. Stick to the PVC or the cage for a cleaner solution.
Installation Tips for Success
When you're finally out in the field ready to mount your homemade deer feeder varmint guard, keep a few things in mind. First, make sure you aren't blocking the solar panel if your feeder has one. It's easy to get carried away with the wire mesh and accidentally shade the very thing that keeps your battery charged.
Second, check the "throw" of your corn immediately after installation. Do a test spin. If you hear a loud clanging sound or see the corn bouncing off the guard and piling up right at the base of the feeder, you might need to trim some of the wire or widen the cage. You want that corn scattered far and wide to keep the deer from bunching up in one spot.
Lastly, make sure the guard is easy to remove or has an access door. At some point, you're going to need to change the battery, fix the timer, or clear a clog. If you've zip-tied the guard on so tight that it takes twenty minutes to get off, you're going to regret it during a cold morning in the woods. Use a couple of simple wing nuts or a hinged design to make maintenance a breeze.
Wrapping Things Up
At the end of the day, a homemade deer feeder varmint guard is one of those projects that pays for itself in a matter of weeks. When you consider the price of corn these days, losing twenty pounds a week to a couple of "trash pandas" adds up fast.
By spending an afternoon with some hardware cloth and a pair of snips, you're ensuring that the feed you buy actually goes to the deer you're hunting. It keeps your equipment from getting broken, saves you money, and gives you a little more peace of mind when you're away from the property. Plus, there's just something satisfying about a DIY fix that actually works better than the store-bought version. Get it built, get it installed, and get back to focusing on your hunt.
