7 Best Cedar Blocks For Moth Repellent To Use
Protect your wardrobe naturally with our top 7 cedar block picks. Discover effective, aromatic solutions to keep moths away and preserve your favorite clothes.
Protecting your hard-earned stash from moth damage is a rite of passage for every dedicated knitter. After spending hundreds of hours on a complex lace shawl or a hand-dyed wool sweater, the last thing you want is to find tiny, heartbreaking holes in your fabric. Integrating aromatic cedar into your storage routine is the most effective, non-toxic way to safeguard your favorite fibers. These seven options provide the reliable defense you need to keep your handknits pristine for years to come.
Woodlore Cedar Fresh Cedar Hang-Ups: Best Overall
When you spend weeks working on a heavy cabled sweater or a complex colorwork cardigan, you need a storage solution that doesn’t just sit on a shelf. These hang-ups are designed to slip right onto your closet rod, placing the cedar scent exactly where your garments are hanging.
Because they feature a hook design, they provide consistent airflow and scent dispersal around the shoulders of your sweaters. This is vital, as moths often target the seams and underarm areas where skin oils and moisture tend to linger.
Unlike small blocks that can get lost in the folds of a garment, these hang-ups stay upright and visible. They are the most reliable way to ensure your entire wardrobe remains protected without the risk of the cedar oils transferring directly onto delicate, light-colored yarns.
Household Essentials Cedar Blocks: Best Value Set
If you have a growing stash of raw wool or finished accessories, buying protection in bulk is a financial necessity. This set provides a large volume of blocks, allowing you to distribute them throughout multiple bins and drawers without breaking your yarn budget.
The versatility of these basic blocks is their greatest strength. You can tuck them between skeins of fingering weight yarn, place them in the corners of your storage bins, or even slip them into the pockets of your finished garments.
Keep in mind that these are untreated, raw cedar, which is exactly what you want for fiber safety. Avoid the temptation to buy "pre-scented" blocks that use artificial oils, as these can leave residue on your precious hand-dyed fibers.
CedarSafe Aromatic Cedar Planks: Best for Shelving
For those of us who display our stash on open shelves, moths can be a constant, looming threat. Cedar planks are the superior choice here because they offer a wider surface area to create a "scent barrier" across the entire width of your shelving unit.
You can lay these flat beneath your stacks of yarn or stand them up against the back of the shelf. This creates a zone of protection that keeps moths from settling into the creases of your folded sweaters or the tops of your yarn cakes.
While they take up more space than smaller blocks, they are incredibly effective at deterring pests in high-traffic storage areas. Just ensure your yarn isn’t pressed directly against the wood if the planks are rough, to avoid snagging delicate mohair or single-ply yarns.
Scented Cedar Co. Cedar Hearts: Best for Drawers
Drawers are notorious for being dark, quiet, and undisturbed—the perfect environment for clothes moths to lay eggs. Cedar hearts are small enough to tuck into the corners of a dresser drawer without taking up valuable space meant for your finished socks or mittens.
Their smooth, heart-shaped profile is specifically designed to be gentle on delicate fibers. You don’t have to worry about sharp edges catching on your lace weight silk or high-twist merino wool as you pull your garments in and out.
They are also aesthetically pleasing, which makes the process of organizing your stash feel a bit more intentional. Drop two or three in each drawer to keep the scent profile strong enough to act as a deterrent.
Evelots Cedar Wood Blocks: Best for Storage Bins
Storing yarn in airtight plastic bins is a great start, but it doesn’t guarantee safety if a moth or larva sneaks in during a packing session. These blocks are the perfect size to toss into the center of a bin filled with wool, alpaca, or cashmere.
Because they are compact, you can place them at different levels within the bin as you pack your yarn. This ensures the scent permeates the entire container, rather than just sitting at the very top.
Always remember that cedar acts as a repellent, not an insecticide. Before you seal your bins for the season, ensure every item is freshly laundered or steam-cleaned; cedar will keep the pests away, but it won’t kill an active infestation already hiding in your fibers.
Richards Homewares Cedar Balls: Best for Corners
Sometimes, you need to reach the tight, awkward corners of a cedar chest or a deep storage trunk where blocks simply won’t fit. Cedar balls are small, mobile, and can be easily tucked into the nooks and crannies where moths love to hide.
I often use these to fill the "dead space" in my project bags or the corners of my knitting baskets. They are particularly useful for protecting small accessories like hats and cowls that might get pushed into the back of a drawer.
Because they are spherical, they have a high surface-area-to-volume ratio, which helps them release their scent effectively. Just be careful if you have small children or pets, as these can easily roll away or be mistaken for toys.
CedarFresh Cedar Cubes: Best for Tight Spaces
If you are dealing with a crowded closet or a very full chest of drawers, you need a solution that is unobtrusive. These cubes are small, stackable, and can be squeezed into the tiny gaps between your yarn storage boxes or finished garments.
They offer a concentrated dose of cedar oil in a very small footprint. If you have a specific "trouble spot"—like a shelf where you keep your most expensive hand-dyed wool—these cubes are perfect for creating a concentrated perimeter.
They are also great for popping into the foot of a boot or the inside of a knitted slipper to keep them fresh. Their small size makes them the most flexible tool in your moth-prevention arsenal.
Why Natural Cedar Is Essential for Fiber Storage
Moths are biologically programmed to seek out protein-based fibers like wool, alpaca, silk, and cashmere. They thrive in dark, undisturbed places, and the natural oils in cedarwood act as a powerful, non-toxic deterrent to these pests.
- Non-Toxic: Unlike chemical mothballs, cedar is safe for you and your pets.
- Aromatic: The scent is pleasant to humans but overwhelming to the olfactory senses of moths.
- Moisture Control: Cedar naturally absorbs small amounts of humidity, which helps prevent the damp conditions that moths love.
Choosing natural cedar means you aren’t introducing harsh, lingering chemicals into your home or onto your skin. Your handknits deserve protection that respects the integrity of the fiber itself.
How to Refresh Your Cedar Blocks for Long-Term Use
The most common mistake knitters make is assuming cedar lasts forever. Over time, the surface of the wood dries out and the essential oils dissipate, rendering the block ineffective.
You can easily restore the potency of your cedar by lightly sanding the surface with a piece of fine-grit sandpaper. This opens up the pores of the wood and releases a fresh burst of the natural oils trapped inside.
- Sand lightly: You only need to remove a thin layer to expose fresh wood.
- Apply oil: Occasionally, you can use a drop of pure cedar essential oil to boost the scent.
- Check monthly: If you can no longer smell the cedar when you open your bin, it is time for a refresh.
Best Practices for Protecting Handknits from Moths
Prevention is always easier than dealing with a moth infestation after the fact. Always wash your garments before storing them for the season, as moths are attracted to the pheromones in body oils, sweat, and food particles.
Store your clean knits in airtight containers or vacuum-seal bags if you live in a high-risk area. If you prefer to keep your knits accessible, ensure your storage area is vacuumed regularly and that you rotate your yarn stash to prevent stagnant air.
- Cleanliness: Never store dirty or worn knits.
- Rotation: Move your yarn around once a month to disturb any potential nesting sites.
- Inspection: Take a few minutes every season to shake out your sweaters and check for any signs of damage.
Investing in quality cedar blocks is a small price to pay for the peace of mind that comes with knowing your handknits are safe. By combining these natural repellents with good storage hygiene, you can ensure your favorite projects stay in your wardrobe for decades. Treat your yarn with care, and it will continue to provide you with warmth and comfort for years to come. Happy knitting, and may your stash remain forever hole-free.
