6 Best Cedar Blocks For Yarn Storage To Keep Moths Away
Protect your yarn collection from moths with our top six cedar block picks. Learn how natural aromatic oils effectively preserve your fibers for years.
There is no heartbreak quite like pulling out a cherished stash of hand-dyed wool only to find the tell-tale holes of moth larvae. As a knitter, your yarn is an investment of time, money, and creative energy that deserves robust protection. Cedar blocks provide a natural, chemical-free barrier that keeps these pests away from your precious fiber. Let’s look at the best options to ensure your stash remains pristine for your next big project.
Woodlore Cedar Fresh Cedar Blocks: Best Overall
When it comes to consistent, long-term protection, Woodlore sets the gold standard for cedar blocks. These are crafted from high-quality Eastern Red Cedar, which is renowned for having a higher concentration of aromatic oils than other varieties.
For the knitter with a dedicated yarn cabinet or a set of storage bins, these blocks are the perfect size to tuck into corners. They are dense enough to hold their scent for a long time, meaning you won’t have to worry about them every single week.
The bottom line here is reliability. If you are storing expensive hand-dyed yarns or rare breed wools, investing in a brand that focuses on the quality of the wood itself is a smart move.
Household Essentials Cedar Blocks: Best Value
If you are just starting to build your stash and need to protect a large volume of yarn without breaking the bank, these blocks are a fantastic entry point. They offer a simple, no-frills approach to pest deterrence that works perfectly for the average knitter.
You get a higher quantity of blocks per package, which is ideal if you store your yarn in multiple smaller bins or plastic totes. I often recommend these for knitters who have a "working stash"—yarn that moves in and out of storage frequently.
Because they are affordable, you don’t have to feel precious about using them in every single bag. Just keep in mind that you may need to sand them slightly more often than premium blocks to keep the scent active.
CedarFresh Cedar Hang-Ups: Best for Closets
Many of us store our finished sweaters or yarn-filled bins in a closet, where floor space is at a premium. These hang-up style cedar pieces are designed to be hooked onto hangers, providing a "zone of protection" for your knitwear.
If you have a collection of hand-knitted cardigans or pullovers, hanging these alongside them is a brilliant strategy. They create a scent barrier that deters moths from settling into the folds of your garments.
Just be careful that the cedar wood doesn’t rub directly against delicate lace or light-colored fibers. While the wood is smooth, it is always best to leave a tiny bit of breathing room between the block and the yarn.
Scented Cedar Blocks by Cedar Space: Best Scent
Sometimes the natural scent of cedar can fade, especially in dry environments. These blocks are specifically designed to be highly aromatic, making them a great choice if you are worried about the effectiveness of your existing storage setup.
The scent is potent without being overwhelming, which is a delicate balance for those of us who keep our yarn in living areas. You don’t want your entire house smelling like a lumberyard, but you do want enough scent to signal that the area is "off-limits" to pests.
If you find that your stash has been sitting in a basement or attic, these are the blocks I would choose to refresh the environment. They provide that extra layer of confidence that your fiber is well-protected.
Stratton Home Decor Cedar Blocks: Best Design
Protection doesn’t have to be purely utilitarian; sometimes it’s nice to have something that looks intentional in your craft room. These blocks are aesthetically pleasing, making them a great choice for open shelving or decorative baskets.
If your yarn storage is part of your home decor, you don’t need to hide these blocks away. They are finished beautifully and won’t look like you’ve just thrown a piece of scrap wood into your bin.
They perform just as well as standard blocks, but they add a touch of polish to your space. It’s a small detail, but for a knitter who spends hours in their studio, a beautiful environment makes the creative process even more enjoyable.
Cedar Valley Natural Cedar Planks: Best Bulk
When you reach the "stash acquisition" stage where you have dozens of bins, individual blocks can become expensive. These larger planks are the most economical way to protect a massive inventory of yarn.
You can place these at the bottom of a large storage bin and layer your yarn on top. Because they are larger, they have a greater surface area, which helps maintain a consistent scent profile throughout the entire bin.
This is the professional approach to stash management. If you are a dedicated knitter who buys yarn in sweater quantities, these planks provide the coverage you need to sleep soundly at night.
Why Cedar Effectively Repels Moths From Yarn
Cedar doesn’t actually kill moths; instead, it acts as a powerful deterrent. The aromatic oils in the wood, known as thujone, create an environment that moths find highly unappealing.
Moths are looking for a safe, undisturbed place to lay their eggs, specifically in protein-rich fibers like wool, alpaca, or silk. By placing cedar in your storage, you are making your yarn bin a "hostile" environment for them.
It is important to remember that cedar is a preventative measure, not a cure. If you already have an active infestation, cedar will not be enough to save your yarn; you will need to quarantine and treat the fibers first.
How to Properly Use Cedar Blocks in Your Stash
The biggest mistake knitters make is thinking that one block will protect an entire closet. You need to distribute your cedar blocks throughout your storage containers to ensure the scent permeates the entire space.
I recommend placing a block at the bottom, middle, and top of your storage bins if possible. This ensures that even if you have a deep stack of yarn, there is no "safe zone" for a moth to land.
Avoid placing the blocks directly against your yarn if you are worried about the oils staining. You can wrap the block in a small piece of muslin or a thin cotton sock to act as a barrier while still allowing the scent to escape.
Maintaining Cedar Scent: Sanding and Refreshing
One of the best features of cedar is that it is renewable. When the scent begins to fade—and it will, usually after a few months—you don’t need to throw the block away.
Simply take a piece of fine-grit sandpaper and lightly rub the surface of the wood. This opens up the pores and releases a fresh wave of aromatic oils, effectively "recharging" the block.
If you don’t have sandpaper, you can even use a nail file in a pinch. This simple maintenance routine ensures that your investment continues to work for years, keeping your yarn safe season after season.
Storing Your Wool Safely: Essential Best Practices
- Clean before storing: Moths are attracted to skin oils, sweat, and food particles. Always wash your hand-knits before storing them for the season.
- Use airtight containers: Plastic bins with locking lids are your best defense against pests entering from the outside.
- Rotate your stash: Don’t let your yarn sit in the dark for years on end. Take it out, admire it, and check for any signs of damage.
- Mind the humidity: Moths love damp, dark places. Ensure your storage area is cool and dry to prevent both pests and mildew.
Protecting your yarn stash is a fundamental part of being a long-term knitter. By choosing the right cedar blocks and following a consistent maintenance routine, you can ensure your favorite fibers remain safe for years. Take the time to set up a secure storage system now, and you will never have to worry about moth damage again. Happy knitting, and may your stash stay perfectly preserved for every project to come.
