7 Best Cedar Blocks For Garment Protection To Use
Protect your wardrobe naturally. Explore our top 7 cedar block picks to repel moths and freshen closets effectively with these durable, aromatic solutions.
Protecting a hand-knit sweater collection is just as important as the hours spent perfecting your tension or mastering a complex cable stitch. Natural fibers like wool, alpaca, and cashmere are delicious to moths, making cedar an essential line of defense in your closet. These seven cedar solutions offer varying levels of protection to ensure your hard work remains moth-free for years. Choosing the right cedar product depends on your storage habits and the specific fibers you keep in your rotation.
Woodlore Cedar Hangers: Best for Heavy Sweaters
When you invest forty hours into a cabled Aran sweater, the last thing you want is for it to lose its shape on a flimsy wire hanger. Woodlore’s heavy-duty cedar hangers provide the structural support needed to keep shoulder seams from stretching while simultaneously repelling pests.
The wide, contoured shoulders are a game-changer for heavy wool garments that are prone to "hanger bumps." By keeping the garment properly draped, you avoid the need for aggressive blocking to fix distorted fabric later.
However, remember that cedar is not a miracle worker; it is a deterrent. If you are storing a heavy, high-moisture-content wool, ensure it is completely dry before hanging it up to prevent mildew.
Household Essentials Cedar Blocks: Best Value
If you have a large stash of hand-knits, buying individual specialty cedar items can get expensive quickly. These basic blocks are a cost-effective way to line every shelf and bin in your fiber storage area without breaking the bank.
They are simple, unadorned, and get the job done efficiently. I like to tuck these into the corners of my plastic storage bins where I keep my seasonal spinning fiber or extra skeins of luxury hand-dyed wool.
Because they are affordable, you can replace them more frequently as the scent fades. Don’t be afraid to use them in bulk; the more surface area you cover, the better the protection for your stash.
CedarFresh Cedar Cubes: Best for Small Drawers
Small drawers often house your most delicate items, like lace-weight shawls or hand-knit silk socks. These small cubes are perfect because they don’t take up precious space that could be used for your yarn or notions.
Their compact size allows you to tuck them into the corners of a drawer without snagging delicate lace work. If you have a drawer full of fine gauge mohair, these cubes are the perfect unobtrusive guardians.
Just be mindful of the raw wood surface against your knitwear. While cedar is generally safe, I always recommend placing a piece of acid-free tissue paper between the block and your fiber to prevent any potential oil transfer.
Scented Cedar Rings: Best for Closet Rods
Closet rods are the primary entry point for pests looking to settle into your favorite cardigans. These cedar rings are designed to slip directly onto your hangers, creating a localized scent barrier around the neck and shoulder area of your knitwear.
They are particularly useful if you live in a climate with high humidity, where moths are more active. By placing a ring on every hanger, you create a "cedar curtain" that makes your closet a much less inviting environment for insects.
If you find the scent too strong initially, let them air out for a few hours before placing them near your favorite garments. They are a passive, low-effort way to add a layer of security to your daily rotation.
Butler Luxury Cedar Blocks: Best for Storage
When you are packing away your winter wools for the summer, you need something robust and long-lasting. Butler Luxury blocks are often thicker and more concentrated, making them ideal for sealed storage containers.
High-quality cedar acts as a natural moisture regulator, which is a secondary benefit for long-term storage. If you live in a damp area, this property is just as important as the moth-repelling scent.
Always ensure your garments are freshly laundered before putting them into storage. Cedar blocks work best in a clean environment; they cannot eliminate existing moth larvae or eggs already embedded in the fibers.
Cedar Valley Cedar Planks: Best for Shelving
If you prefer to store your sweaters folded on shelves, flat cedar planks are your best friend. They provide a stable, aromatic base for your stack and ensure that the bottom layer of your knitwear isn’t sitting directly on a dusty or untreated shelf.
These planks are excellent for organizing your "yarn library" or storing finished projects that aren’t currently in rotation. They cover a wide surface area, ensuring the scent permeates the entire stack of folded garments.
Be aware that cedar oils can occasionally stain light-colored fabrics if left in direct contact for years. Place a thin layer of cotton or acid-free paper between the plank and your lightest-colored wools to be safe.
Whitmor Cedar Sachets: Best for Knit Garments
Sometimes you need a solution that is soft and flexible, especially when tucking protection between layers of a delicate hand-knit. Sachets filled with cedar shavings are gentle and won’t leave hard impressions on your fabric.
These are perfect for layering inside a sweater box or tucking into the sleeve of a cardigan. Because they are porous, they release the cedar scent effectively while remaining soft to the touch.
They are also great for those who find the scent of solid blocks too intense. The fabric casing acts as a natural diffuser, providing a subtle, consistent protection that is ideal for fine fibers like cashmere or angora.
Why Cedar is Essential for Natural Fiber Care
Natural fibers, particularly animal proteins like wool, alpaca, and mohair, are essentially food for moth larvae. While a clean closet is your first line of defense, cedar provides a natural, chemical-free way to deter pests.
Unlike synthetic mothballs, which smell like chemicals and can linger in your fibers, cedar is a natural oil-based repellent. It works by masking the scent of the natural fibers that moths use to locate their next meal.
Remember that cedar doesn’t kill existing infestations. If you see signs of damage—like tiny holes or webbing—you must treat the garment with heat or cold before using cedar for ongoing prevention.
How to Refresh Your Cedar Blocks for Long Life
The biggest mistake knitters make is assuming cedar blocks last forever. Over time, the surface oxidizes and the aromatic oils evaporate, rendering the block ineffective.
To refresh them, simply take a piece of fine-grit sandpaper and lightly sand the surface of the wood. This exposes fresh, oil-rich wood grain and reactivates the scent.
If you don’t have sandpaper, a quick wipe with a damp cloth can sometimes help, but sanding is the gold standard. Aim to refresh your blocks every three to six months to keep your stash fully protected.
Best Practices for Seasonal Knitwear Storage
Never store a sweater that has been worn, even once, without washing it first. Moths are attracted to human skin oils, sweat, and food particles, which act as a beacon for pests.
Always use breathable storage containers, such as cotton garment bags or acid-free boxes. Plastic bins can trap moisture, leading to mold or mildew, which can be just as destructive to your hand-knits as moths.
Finally, keep your storage area in a cool, dark, and dry location. By combining clean garments, breathable storage, and refreshed cedar blocks, you ensure your hand-knit treasures remain in pristine condition for years to come.
Taking care of your hand-knits is a labor of love that extends far beyond the final bind-off. By incorporating these cedar solutions into your storage routine, you are protecting the time, money, and creativity you poured into your projects. Stay mindful of your fiber needs, keep your storage clean, and your sweaters will stay beautiful for a lifetime. Happy knitting, and may your closet remain forever moth-free.
