6 Best Cedar Blocks For Garment Protection In Storage

Nothing spoils the anticipation of a summer climbing trip or a winter backcountry tour like pulling your favorite base layers out of storage, only to find them riddled with tiny, moth-inflicted holes. Protecting high-performance fabrics from pests requires more than just a clean closet; it demands a proactive, natural defense system that keeps gear pristine for the next season. Investing in quality cedar protection ensures that your technical apparel remains ready for the trail, rather than destined for the trash.

Household Essentials Cedar Blocks: Best Overall

For the gear enthusiast who wants a reliable, no-nonsense solution for various storage containers, Household Essentials Cedar Blocks hit the sweet spot. These blocks offer a versatile shape that fits easily into the corners of plastic totes or tucks into the pockets of fleece jackets. They provide a solid, consistent level of aromatic protection without taking up valuable volume in a packed gear bin.

The beauty of this choice lies in its sheer utility across different types of storage, from small dry bags to large alpine packs. They are an ideal pick for those who rotate gear frequently and need a dependable, low-profile deterrent. If the goal is a simple, effective foundation for a seasonal gear rotation, these blocks are the standard-bearer.

Cedar Space Red Cedar Rings: Best for Hangers

When storing down jackets or technical mid-layers, hanging them is often superior to stuffing them into bins to maintain loft and structure. Cedar Space Red Cedar Rings are engineered specifically for this purpose, featuring a center hole that slides perfectly onto standard wooden or plastic hangers. This placement ensures the scent permeates the garment from the collar down, where pests are most likely to investigate.

These rings are particularly effective for expensive shells or insulation layers that spend months inside a closet. By hanging them alongside your gear, the natural oils act as a continuous, subtle barrier against moths. For anyone who prioritizes garment shape and immediate accessibility for a quick weekend getaway, these rings are an essential closet addition.

Woodlore Cedar Blocks: Best for Wool Base Layers

Merino wool is the gold standard for temperature regulation on the trail, but it is also a magnet for fabric-eating insects. Woodlore Cedar Blocks are crafted from high-quality, dense Eastern Red Cedar, which packs a more concentrated scent profile necessary to protect delicate natural fibers. Because they are slightly heavier and more robust, they provide a reliable barrier that lasts longer than thinner, mass-produced alternatives.

These blocks are highly recommended for those who own specialized wool kits for thru-hiking or cold-weather hunting. Their durability means they won’t splinter or degrade quickly when shifted around in a gear closet. If the gear inventory includes a significant investment in wool, choosing a high-density option like Woodlore is a smart move for long-term protection.

Colton’s Naturals Cedar Blocks: Best Scent

Strength of scent is the primary indicator of how much aromatic oil remains in cedar, and Colton’s Naturals are known for a potent, fresh-cut aroma. When gear has been stored in a damp shed or a garage, a strong-smelling deterrent is necessary to mask the organic odors that might otherwise attract pests. These blocks are for the user who values a powerful, natural scent profile to guard their prized equipment.

These blocks are an excellent choice for sealed storage environments, such as airtight plastic bins, where the scent can become concentrated. Because they retain their potency longer, they require less frequent refreshing than cheaper options. For those who prioritize a strong, immediate scent barrier, this product provides the most robust olfactory defense.

Richards Homewares Cedar Cubes: Best Budget Pick

When outfitting a large storage space or multiple gear bins, the costs of individual protection units can add up quickly. Richards Homewares Cedar Cubes provide an economical solution that allows for saturation coverage without blowing the budget. Because they are smaller, they can be scattered throughout a bin to ensure no corner of the container remains unprotected.

These are the ideal choice for someone managing a massive collection of spare gear or multiple seasons’ worth of clothing. While they might need refreshing more often than premium blocks, their low cost makes it easy to add extra units to every layer of packed items. For the pragmatic planner who needs to protect a high volume of gear, these cubes provide the most value.

Giles & Kendall Cedar Planks: Best for Large Bins

Large gear bins used for long-term storage of off-season equipment require more surface area than a single block can offer. Giles & Kendall Cedar Planks are essentially raw, unvarnished cedar, providing a massive amount of aromatic surface area in a single piece. They can be placed at the bottom of a container to create a base layer of scent that rises through the entire stack of clothing.

These planks are perfect for serious storage setups, such as a large bin holding a multi-day backpacking tent, sleeping bag, and bulky winter gear. Their size prevents them from getting lost between items, ensuring the scent stays active throughout the entire storage duration. For those who want to “set and forget” a large bin for six months or more, these planks are the superior choice.

Why Cedar Beats Mothballs for Gear Storage

Mothballs contain chemicals like naphthalene or paradichlorobenzene, which are essentially pesticides that off-gas toxic fumes. These substances are not only harsh on the environment but can leave a lingering, unpleasant odor that is difficult to remove from technical fabrics. Furthermore, their toxicity poses a safety risk if handled incorrectly, especially in households with pets or children.

Cedar, by contrast, acts as a natural, safe repellent that works by masking the scents pests use to locate food sources. It doesn’t rely on chemical poisoning, making it far superior for high-performance gear that you intend to wear directly against your skin. Opting for cedar means your gear remains clean, breathable, and ready for the trail without the need for an intensive washing process after removal from storage.

How to Refresh Your Cedar Blocks Safely Over Time

Over time, the natural oils that give cedar its repellent properties will dry out, reducing the effectiveness of the wood. To refresh them, gently sand the surface of the block with a piece of fine-grit sandpaper until the rich, red color and strong scent return. This simple process exposes fresh wood fibers and releases the aromatic oils trapped just beneath the surface.

Avoid using chemical sprays or artificial cedar oils to “recharge” the blocks, as these can ruin the wicking properties of technical fabrics. Natural sanding is the only method that maintains the integrity of the wood and the safety of your gear. Aim to refresh your blocks at the start of every major season change, such as when transitioning from summer hiking to winter snowsports.

Prepping Merino Wool and Fleece for Long Storage

Before putting any gear into storage, ensure it is thoroughly cleaned and dried to remove any trace of body oils, salt, or food particles. Pests are attracted to the microscopic debris left behind by sweat and trail grime, regardless of how much cedar is in the bin. Always wash your merino wool and fleece using a mild detergent, ensuring they are completely bone-dry before placing them near cedar.

If you are storing items for an extended duration, fold them loosely to avoid creating permanent creases that can weaken synthetic fibers. Placing a layer of acid-free tissue paper between delicate items can further prevent abrasion and add a secondary layer of protection. A clean, dry, and cool environment is the single most important factor in keeping gear safe for the long haul.

Optimal Cedar Block Placement in Bins and Closets

In a plastic bin, placement is all about airflow and scent distribution. Do not place the cedar directly against delicate synthetic membranes or waterproof coatings, as the concentrated oils can occasionally cause staining. Instead, wrap the blocks in a thin piece of cotton fabric or place them on top of a clean sheet of paper to create a buffer.

For closets, distribute your cedar blocks or rings evenly across different levels to ensure the scent envelops all hanging gear. Use more units in confined, air-tight spaces and fewer in well-ventilated areas where the scent can dissipate quickly. Consistently monitoring the scent level ensures you stay ahead of the game, keeping your gear safe for your next big adventure.

Proper gear maintenance is just as important as the planning that goes into a big trip. By utilizing the right cedar protection, you ensure that your investment in quality apparel pays off for years of trekking and climbing. Keep your gear ready, keep your storage organized, and keep your sights set on the next peak.
