7 Best Natural Cedar Blocks for Repelling Pests in Storage

Discovering a moth hole in a favorite wool sweater or finding evidence of pests in seasonal storage is a frustrating experience for any homeowner. Natural cedar wood offers a chemical-free, aromatic solution that protects fabrics without the harsh odors or potential health concerns associated with synthetic mothballs. Selecting the right cedar products involves matching the form factor to the specific storage environment to ensure maximum effectiveness.

CedarFresh Value Pack: Best for Whole-Home Use

When tackling a large-scale seasonal swap, such as moving winter coats into storage or packing away quilts, efficiency and cost-effectiveness take center stage. The CedarFresh Value Pack provides a high volume of aromatic cedar pieces that allow for comprehensive coverage across multiple closets and storage bins. Having a bulk supply ensures that every corner of a storage area receives protection, rather than leaving gaps where pests might settle.

This option serves those who prefer a “set it and forget it” approach for large storage projects. Because the set includes various shapes, it works well for households managing multiple types of inventory, from bedding to heavy outerwear. The primary trade-off is the lack of specialized mounting hardware, but for the price, the ability to scatter these throughout a home is unmatched.

Bottom line: Choose this pack for budget-conscious homeowners who need to cover large spaces quickly without purchasing multiple specialized kits.

Homode Cedar Rings: Best for Closet Hangers

Closet space often feels like a puzzle, especially in older homes where rod space is at a premium. Cedar rings are designed with a circular cutout that slips easily onto the neck of standard wooden or plastic hangers, placing the scent directly against the fabric of shirts and jackets. This design maximizes vertical space, ensuring that protection occupies no extra footprint on the closet rod.

These rings work exceptionally well for professional wardrobes that stay in the closet throughout the year. Because they sit at the shoulder level of the garment, the natural oils dissipate exactly where moths typically land. While they are small, using one per hanger ensures consistent, targeted protection for high-value pieces.

Bottom line: These are the ideal choice for maximizing narrow closet spaces while protecting daily-wear garments.

Household Essentials Sachets: Best for Drawers

Dressers and under-bed storage drawers present a unique challenge, as traditional blocks can snag delicate fabrics or take up too much precious room. Sachets provide a contained, breathable solution that keeps the aromatic wood shavings off the clothing while allowing the scent to circulate effectively. They act as a subtle buffer between the wood of the drawer and the folded linens.

These sachets are particularly useful for protecting lingerie, cotton tees, or delicate knitwear that might be damaged by direct contact with raw, unfinished cedar. Because they are lightweight and soft, they can be tucked into the corners of drawers without creating unsightly bulges. They are also easily moved when rotating seasonal items.

Bottom line: Select sachets for delicate items that require soft, non-abrasive protection within tight drawer spaces.

Woodlore Cedar Blocks: Best for Storage Bins

Storage bins in basements, attics, or garages are prone to stagnation, making them prime targets for pests. Rectangular cedar blocks offer a sturdy, dense mass of wood that releases a consistent, long-lasting scent specifically designed for enclosed environments. Their shape allows them to be wedged between stacks of folded clothes or placed on top of packed items without shifting around.

Unlike smaller rings or balls, these blocks contain a significant amount of aromatic heartwood, which provides a stronger barrier in large plastic bins. For homeowners storing out-of-season holiday decor or heirloom linens, these provide a reliable layer of insurance. They are durable enough to be reused for years, making them a wise long-term investment.

Bottom line: Use these blocks to provide heavy-duty, long-lasting protection for deep-storage containers and large plastic bins.

CedarAmerica Planks: Best for Lining Shelves

When converting a standard wire or particle-board shelf into a protective haven for textiles, cedar planks are the gold standard. These flat, wide pieces are designed to lay directly on closet or pantry shelves, creating a fragrant base for towels, sweaters, or wool blankets. They effectively transform a simple storage area into a specialized cedar-lined zone.

These planks are especially beneficial for renters who cannot modify closet interiors but want the benefits of a cedar-lined wardrobe. They create a physical barrier that prevents delicate fabrics from touching potentially dusty or unfinished surfaces. Their weight ensures they stay in place, while their surface area provides maximum scent dispersion.

Bottom line: Invest in planks to create a permanent, protective barrier for shelf-bound linens and folded garments.

Acmetop Cedar Balls: Best for Shoes and Boots

Footwear stored in entryways or mudrooms often traps moisture, which can attract pests and create unpleasant odors. Cedar balls are small, versatile, and designed to roll into the toes of shoes or deep into the shafts of tall boots where other storage products cannot reach. They absorb moisture while neutralizing odors, acting as both a pest repellent and a deodorizer.

Because they are small and lightweight, they are easy to manage in households with limited space. Keep a small bowl of them near the door for a quick-access supply when putting away out-of-season boots. They provide a simple, low-cost way to extend the lifespan of footwear by keeping the interior environment dry and hostile to insects.

Bottom line: Use cedar balls for narrow or hard-to-reach areas, specifically within shoes and boots that require moisture control.

The Container Store Blocks: Best Premium Option

For homeowners who prioritize aesthetic consistency and high-quality, dense cedar, branded blocks from specialized retailers offer a noticeable difference in finish and scent longevity. These blocks are typically sanded to a smooth, splinter-free texture and crafted from premium-grade red cedar, which contains a higher concentration of the oils responsible for repelling pests. They serve as a reliable, long-term organizational tool that looks as good as it functions.

While they carry a higher price point, the quality of the wood translates to fewer replacements and a more refined appearance in visible storage areas. These are excellent for walk-in closets where the homeowner wants a uniform, tidy look. When treated as an organizational investment, their longevity justifies the initial cost.

Bottom line: Choose these for high-end closet systems where you want a clean, professional look combined with superior, high-oil wood quality.

How to Refresh Your Cedar’s Scent and Power

Cedar works by releasing natural oils into the air, and over time, the outer surface of the wood will dry out. To restore the potency of any cedar product, lightly sand the surface with fine-grit sandpaper until the rich, red color and strong scent return. This simple maintenance step reveals fresh wood fibers and effectively “recharges” the block, ring, or ball.

• Always sand in a well-ventilated area to avoid inhaling dust.
• Wipe the pieces with a dry cloth before placing them back against fabric to ensure no wood dust stains your clothes.
• For even better results, a drop of pure cedarwood essential oil can be applied directly to the wood to boost its effectiveness.

Bottom line: Never discard cedar just because the scent fades; simple maintenance can extend its life by several years.

How Much Cedar to Use in Bins, Drawers & Closets

Effective pest control requires enough cedar scent to saturate the air in a confined space. A single block in a massive walk-in closet will be ineffective, while over-packing a small drawer can be overkill. Aim for a balanced ratio that ensures the scent is present but not overwhelming.

• Drawers: Two sachets or three cedar balls are usually sufficient for a standard dresser drawer.
• Storage Bins: Place one block in each corner of a large plastic tote to create a continuous barrier.
• Closets: Use a combination of hanging rings on every hanger and planks on the shelves to ensure complete coverage.

Bottom line: Over-estimate rather than under-estimate; cedar is non-toxic and more is always better than not enough in tightly packed storage areas.

Blocks vs. Sachets: Choosing the Right Shape

Choosing between blocks and sachets often comes down to the surface the cedar will touch. Blocks are dense and durable, making them perfect for “set and forget” storage in bins or on solid shelves where they won’t snag fabrics. They offer a strong, steady release of oils over a long period but require careful placement to avoid direct contact with delicate materials.

Sachets, by contrast, are safer for direct contact with clothing because the fabric pouch acts as a barrier. They are lightweight, flexible, and ideal for small spaces like drawers or luggage. While they may need replacement or refreshing more often than solid blocks, they offer convenience and versatility for everyday use.

Bottom line: Use solid wood shapes for long-term storage and sachets for everyday items that require frequent movement.

Properly utilized, natural cedar remains the most reliable and accessible method for protecting home textiles from unwanted pests. By matching the specific product shape to the storage scenario, you can create an environment that stays fresh, organized, and secure throughout the changing seasons. Whether through simple rings for hanging clothes or durable blocks for heavy-duty bins, this classic solution provides peace of mind for any household.
