Why Raccoons Are a Threat to Your Feed Room

Raccoons are not just simple scavengers; they possess remarkable problem-solving abilities and highly adaptable front paws that function much like human hands. A standard feed room filled with sweet feed, scratch grain, and laying pellets is an irresistible jackpot. Once a raccoon identifies a reliable food source, it will return nightly, often bringing family members and teaching them how to access the bounty.

Beyond the immediate financial loss of ruined feed, these pests introduce serious biosecurity risks to a small-scale farm. Their feces can carry Baylisascaris procyonis (raccoon roundworm), which is highly infectious and dangerous to both livestock and humans. Furthermore, their sharp claws and teeth can cause structural damage to wooden doors, siding, and screens as they claw their way inside.

Relying on simple latches or thin plastic containers is a recipe for failure. A successful defense strategy requires a multi-layered approach that secures the perimeter of the room, reinforces individual storage containers, and utilizes locking mechanisms that require human dexterity to open.

Metal Feed Bin – Behrens 31-Gallon Steel Can

The primary line of defense inside any feed room is the storage container itself. While plastic bins are lightweight, hungry raccoons can easily chew through them, leaving a mess of ruined feed and plastic shards. A heavy-duty galvanized steel can prevents chewing entirely and keeps the scent of grain contained, reducing the initial attraction.

The Behrens 31-Gallon Steel Can stands out as the industry standard for small-scale feed storage. Made in the USA from 100% galvanized steel, this can is rust-resistant, rodent-proof, and won’t absorb odors like plastic does. Its large capacity comfortably holds up to 100 pounds of dry feed, making it ideal for managing poultry scratch, goat pellets, or sweet feed.

• Capacity: 31 Gallons (holds approximately 100 lbs of feed)
• Material: Heavy-gauge galvanized steel
• Key Features: Deep-seated zinc lid, offset bottom to keep the can off the ground, large wire handle

While the lid fits snugly, a determined raccoon can still knock the can over to pop the lid off. To make this setup truly predator-proof, the lid must be secured to the handle using a heavy-duty clip or strap. This can is perfect for any hobby farmer looking to upgrade from chewed-up plastic bins, though it does require a flat, dry floor to prevent bottom moisture buildup over time.

Safety Hasp – National Hardware N100-111 Hasp

A secure feed room door is useless if the latch can be easily manipulated by a raccoon’s sensitive paws. Simple hook-and-eye latches or sliding bolts are easily solved by these curious animals. A heavy-duty safety hasp forces the locking mechanism to be completely covered, preventing pests from getting leverage to pry or wiggle the lock open.

The National Hardware N100-111 Hasp offers the rugged durability needed for exterior barn doors and feed room entryways. This heavy-gauge steel hasp features a zinc-plated finish that resists weathering and rust in damp barn environments. Its smart design includes hidden screws when the hasp is closed, preventing raccoons or intruders from tampering with the mounting hardware.

• Size: 3-1/4 inches
• Material: Zinc-plated steel
• Security: Concealed screws when locked, swivel staple for easy latching

Installation requires a solid wooden door frame; mounting this on rotted or thin wood will allow a strong animal to rip the entire unit out. It is the ideal choice for farmers upgrading their main feed room door or heavy wooden bin lids. However, it must be paired with a padlock or snap hook, as the swivel staple alone will not keep a raccoon out.

Padlock – Master Lock 140D Solid Brass Lock

Once a safety hasp is installed, it must be locked with something that requires human tools or complex coordination to open. Raccoons can easily manipulate loose pins, carabiners, or simple clips. A keyed padlock provides absolute security, ensuring that no amount of shaking, pulling, or clawing will open the door.

The Master Lock 140D Solid Brass Lock is a reliable, rust-resistant option that stands up to the harsh conditions of a barn. Its solid brass body resists corrosion from humidity and animal waste, while the hardened steel shackle offers excellent cut resistance. The four-pin cylinder mechanism is smooth to operate, even when your hands are cold or dusty from farm chores.

• Body Width: 1-9/16 inches (40mm)
• Shackle Diameter: 1/4 inch
• Keying: Keyed alike options available for multi-lock setups

Keep in mind that using keyed locks means keeping a key handy during chore time, which can be inconvenient in the dark. For maximum efficiency, purchase a multi-pack keyed alike so one key opens every lock in the yard. This lock is best for farmers who need absolute security on main exterior doors, rather than interior bins that are accessed multiple times a day.

Understanding Raccoon Behavior and Strength

To build an effective defense, one must understand the adversary. Raccoons possess highly developed tactile senses, with forepaws that contain more nerve endings than those of most other mammals. This allows them to "see" with their hands, feeling for weak spots, loose screws, and gaps in the dark without needing visual light.

They are also surprisingly strong and persistent. An adult raccoon can weigh up to 20 pounds or more, enabling them to lift heavy lids, tear away weak wire mesh, and squeeze through gaps as small as four inches. If they smell feed, they will spend hours working at a single entry point, utilizing their body weight to pry open loose boards.

This behavior means that "good enough" solutions will eventually fail. Prevention relies on eliminating scent cues, reinforcing every joint, and using locking mechanisms that require opposable thumbs and significant force to operate. Designing your feed room with these traits in mind saves both feed and structural repair costs down the road.

Spring Snap Hook – National Hardware N222-114

Keyed padlocks are great for security, but opening them multiple times a day during feeding chores can become tedious. A spring snap hook provides a fast, one-handed alternative for securing interior feed bins and secondary latches. It utilizes a spring-loaded gate that requires a specific pinching motion that raccoons struggle to replicate.

The National Hardware N222-114 Spring Snap Hook is built from durable stainless steel, making it completely immune to rust in damp barn air. The heavy-duty spring mechanism remains stiff and reliable over years of daily use, ensuring the gate won’t sag or stick open. Its smooth, snag-free design prevents it from catching on clothing or feed bags during busy chore times.

• Length: 3-1/8 inches
• Material: Stainless steel
• Working Load Limit: 280 pounds

While highly effective, some exceptionally clever raccoons have been known to solve simple snap hooks if they can get both paws around them. For maximum safety, mount the snap hook in a downward-facing position or pair it with a tight-fitting chain. This is the perfect daily-use latch for interior metal bins, but should not replace a keyed lock on exterior-facing doors.

Hardware Cloth – Fencer Wire 19-Gauge Mesh

Standard window screening or chicken wire is useless against a raccoon’s sharp claws and teeth. Chicken wire is designed to keep chickens in, not predators out; raccoons can easily tear it apart or chew through the thin wire. To protect soffits, vents, and windows in your feed room, you need a rigid, heavy-gauge steel mesh.

The Fencer Wire 19-Gauge Mesh hardware cloth provides an impenetrable barrier against pests of all sizes. This hot-dipped galvanized wire features a 1/2-inch square mesh that blocks both large raccoons and tiny mice. The double zinc coating ensures it won’t rust when exposed to rain, snow, or humid barn air, maintaining its structural integrity for years.

• Mesh Size: 1/2 inch x 1/2 inch
• Wire Gauge: 19-gauge
• Roll Dimensions: Available in various widths (e.g., 24, 36, or 48 inches)

Working with 19-gauge hardware cloth requires heavy-duty wire cutters and thick leather gloves, as the cut edges are incredibly sharp. It must be secured using heavy U-nails or screws with washers, rather than simple staples which can be easily pried out. This is an essential purchase for sealing up foundation vents, window openings, and eaves in any wooden feed shed.

Storage Tote – Rubbermaid Commercial Brute Tote

While metal cans are superior for grain, some feed room items like supplements, medication, or pre-packaged treats are better stored in stackable containers. Standard home-storage plastic totes are brittle and easily chewed through by determined pests. A heavy-duty, impact-resistant commercial tote is required to keep these expensive supplies safe.

The Rubbermaid Commercial Brute Tote is engineered to withstand extreme abuse in agricultural and industrial environments. Made from high-density polyethylene, this tote resists cracking, crushing, and chewing, even in sub-zero winter temperatures. The tight-fitting lid snaps securely into place, while the reinforced handles feature drain holes to prevent water accumulation if stored near open windows.

• Capacity: 20 Gallons
• Material: Commercial-grade polyethylene
• Features: Snap-on lid, reinforced rib base, ergonomic handles

Although highly durable, these totes are not 100% chew-proof against a persistent raccoon if left in an unsecured area for long periods. They are best used inside a reinforced feed room for organized storage of bagged supplements, tools, or veterinary supplies. This tote is a great fit for farmers who need stackable, weather-resistant storage but should not be used as the sole protection for high-value sweet feed.

Tips for Reinforcing Your Feed Room Structure

Securing individual bins is only half the battle; the feed room itself must act as a fortress. Start by inspecting the exterior of the building during the day, looking for any gaps larger than two inches. Pay close attention to the roofline, soffits, and the area where the walls meet the floor, as these are common entry points.

Reinforce weak wooden siding by backing it with hardware cloth on the inside. If your feed room has a dirt or gravel floor, raccoons and rats can easily dig underneath the walls; consider pouring a concrete pad or laying down a barrier of heavy pavers. Ensure all window screens are replaced with steel mesh secured with screws and washers rather than staples.

Additionally, cut back any overhanging tree branches within ten feet of the roof. Raccoons are excellent climbers and will use trees as launching pads to access weak spots in your roof or eaves. A secure structure reduces the pressure on your individual feed bins, creating a double-barrier defense system.

Motion Sensor Light – Mr. Beams MB390 LED

Raccoons are nocturnal animals that prefer to work under the cover of complete darkness. A sudden blast of bright light is often enough to startle them and send them scurrying back to the woods. Installing motion-activated lighting around the exterior of your feed room acts as an active deterrent before they even reach the door.

The Mr. Beams MB390 LED spotlight is an ideal choice for remote barns and feed sheds that lack electrical wiring. This battery-operated unit delivers 300 lumens of bright light, easily illuminating a wide area around your feed room entrance. Its sensitive motion detector triggers instantly when movement is detected within 25 feet, and the weather-resistant design ensures reliable operation in rain or snow.

• Brightness: 300 Lumens
• Power Source: 4 D-cell batteries (not included)
• Coverage: 400 square feet

Because it is battery-powered, you must monitor the battery life, especially during cold winter months when battery performance drops. Mount the light high enough to prevent raccoons from reaching it, but low enough to easily access for battery changes. This light is perfect for off-grid outbuildings, but farmers with wired electricity may prefer a permanent floodlight setup.

Door Sweep – M-D Building Products 36-Inch Sweep

The gap at the bottom of a feed room door is a major vulnerability. Raccoons can slip their paws under a door with a one-inch gap, using their leverage to pull, shake, or chew the wood until they create a larger opening. A heavy-duty door sweep seals this gap, blocking drafts, light, and pest access.

The M-D Building Products 36-Inch Sweep features a rugged aluminum body paired with a durable vinyl seal. Unlike cheap felt or thin rubber sweeps, this heavy-duty vinyl strip resists tearing and chewing from persistent pests. The pre-drilled holes make installation straightforward on either wood or metal doors, providing a tight seal against uneven barn floors.

• Length: 36 inches (can be cut to size)
• Material: Aluminum and heavy-duty vinyl
• Mounting: Screw-on (screws included)

Note that if your barn floor is highly uneven or made of rough gravel, the vinyl seal may wear out prematurely or catch on high spots. It is best installed on doors that open inward or over flat concrete thresholds. This sweep is an essential finishing touch for any exterior-facing feed room door to keep out both raccoons and smaller rodents.

Maintaining Your Feed Room to Keep Pests Out

Building a predator-proof feed room is not a set-it-and-forget-it project. Over time, hinges sag, wood swells, and screws loosen under the constant pressure of daily use. Establish a monthly routine to inspect all latches, hinges, and sweeps, tightening any loose hardware immediately before pests can exploit the weakness.

Cleanliness is your best preventative defense. Sweep up any spilled grain or dust immediately, as even a small amount of spilled sweet feed can attract raccoons from miles away. Keep trash cans sealed, and never leave open bags of feed sitting on the floor, even temporarily during chore time.

Finally, rotate your feed stock to ensure older bags are used first, which helps prevent pests from nesting undisturbed behind stacked supplies. By combining heavy-duty physical barriers with rigorous sanitation habits, you can keep your feed investment safe, dry, and free from unwanted nocturnal visitors.

Protecting your feed room from clever raccoons requires combining durable physical barriers with consistent daily habits. By investing in heavy-duty metal bins, secure locking hardware, and structural reinforcements, you can safeguard your livestock’s nutrition and prevent costly waste. A secure feed room brings peace of mind, knowing your hard work and resources are protected through every season.
