7 Best Cedar Blocks For Moth Prevention To Use Now
Protect your wardrobe naturally with our top 7 cedar block picks. Discover how these aromatic wood essentials effectively repel moths and preserve your clothes.
After spending months pouring love into a hand-knit sweater, the last thing you want to discover is a series of tiny, heartbreaking holes caused by clothes moths. These pests thrive on the protein in natural fibers like wool, alpaca, and silk, making your precious stash their favorite buffet. Cedar is a time-honored, non-toxic deterrent that keeps your handknits safe without the harsh chemical smell of traditional mothballs. Here are the best cedar options to safeguard your hard work throughout the changing seasons.
Woodlore Cedar Fresh Cedar Blocks: Best Overall
When it comes to consistent, reliable protection, these blocks are the gold standard for a reason. They are crafted from high-quality American red cedar, which contains the natural oils that repel moths.
I often recommend these for those who have a mix of fibers in their closet. Whether you are storing a heavy, cabled wool gansey or a delicate lace shawl, these blocks provide the steady, aromatic barrier needed to keep pests at bay.
The density of the wood allows for a slow release of scent. This longevity is crucial, as you don’t want to be swapping out your protection every few weeks while you’re busy working on your next project.
Household Essentials Cedar Blocks: Best Value
If you are looking to protect a large stash of yarn or a growing collection of finished garments, buying in bulk is the only way to go. These blocks offer the best price-per-unit without sacrificing the integrity of the cedar.
You can tuck these into every corner of your storage bins or scatter them between layers of folded sweaters. Because they are affordable, you won’t feel guilty about using them liberally.
Just remember that value doesn’t mean "set it and forget it." Even the most budget-friendly cedar needs a little maintenance to stay effective against hungry larvae.
CedarFresh Hanging Cedar Planks: Best for Closets
Closets are tricky environments because of the airflow and the sheer volume of garments hanging on racks. These hanging planks are specifically designed to bridge the gap between your favorite wool coat and the rest of your wardrobe.
The hook design allows them to sit directly on the rod, creating a protective "zone" around your garments. This is perfect for those heavy winter sweaters that spend months in storage during the warmer seasons.
I find these particularly useful for items that are too bulky to fold neatly into bins. They ensure that your long-term storage pieces remain protected without taking up precious shelf space.
Scented Cedar Blocks by CedarSpace: Best Scent
Sometimes, the natural scent of cedar fades, and you need a little boost to keep your closet smelling fresh. These pre-scented blocks are ideal if you want an extra layer of protection and a pleasant, woody aroma.
They are excellent for those who find the subtle scent of raw cedar a bit too faint. The added fragrance acts as a secondary deterrent, making your storage area less inviting to moths.
Be mindful, however, if you are sensitive to scents. While the cedar is natural, the added oils might be potent in a very small, enclosed drawer.
Stratton Cedar Blocks: Best for Storage Bins
When you are packing away your handknits for the season, the way you layer your storage matters. These blocks are shaped perfectly to sit flat at the bottom or top of a storage bin without snagging your yarn.
I always advise knitters to place these between layers of acid-free tissue paper. This prevents the raw wood from coming into direct contact with delicate fibers like mohair or angora, which can sometimes catch on the wood grain.
They are compact enough to fit into the nooks of a project bag or a plastic storage tub. Their size makes them a versatile choice for any knitter’s organizational system.
Whitmor Natural Cedar Blocks: Best Basic Option
Sometimes, you just need a straightforward solution that works without any bells or whistles. These basic cedar blocks are exactly what they claim to be: reliable, natural, and effective.
They are perfect for the beginner knitter who is just starting to accumulate a stash and needs to protect their first few skeins. You don’t need a complex system; you just need to place them where the moths are likely to hide.
Keep in mind that these are simple pieces of wood. They are a utility item, not a decorative one, so focus on their placement rather than their appearance.
Cedar Valley Premium Cedar Blocks: Best Durability
Durability is key when you are investing in long-term storage solutions. These blocks are made from high-quality, thick cuts of cedar that hold onto their essential oils longer than thinner, cheaper alternatives.
If you are storing heirloom pieces—like that intricate stranded colorwork sweater you spent a year on—you want the peace of mind that these blocks provide. They are robust and stand up well to repeated sanding and refreshing.
Think of these as an investment in the longevity of your fiber arts. A sturdier block means fewer replacements and less worrying about whether your protection is still active.
How to Properly Refresh Your Cedar Moth Blocks
Cedar works by releasing essential oils that moths find repulsive. Over time, the surface of the wood dries out, and the scent dissipates, meaning it’s time to intervene.
- Light Sanding: Use a fine-grit sandpaper to gently buff the surface of the block. This exposes fresh wood fibers and releases a new wave of aromatic oils.
- Cedar Oil: If sanding doesn’t bring back the scent, you can apply a tiny drop of pure cedar essential oil to the wood.
- Consistency: Aim to refresh your blocks every 3 to 6 months. Set a reminder on your phone or mark your calendar to ensure you don’t forget.
Where to Place Cedar for Maximum Moth Protection
Placement is just as important as the quality of the cedar you choose. Moths love dark, undisturbed, and slightly humid environments, which is exactly why our closets and bins are so attractive to them.
- Near the Fold: Place blocks directly inside your storage bins or drawers.
- High and Low: Moths can be sneaky; place blocks at the top and bottom of your closet to ensure the scent permeates the entire space.
- Don’t Overcrowd: Ensure there is enough airflow for the scent to travel. If your closet is packed too tightly, the cedar won’t be able to protect the items in the center of the stack.
Essential Tips for Storing Your Handknits Safely
Before you even think about cedar, you must ensure your garments are clean. Moths are attracted to the oils, skin cells, and food particles left on fibers, so always wash your handknits before long-term storage.
- Use Breathable Containers: Avoid plastic bags that trap moisture, as this can encourage mold. Opt for cotton garment bags or acid-free storage boxes.
- The "Deep Freeze" Method: If you suspect an infestation, seal your items in a plastic bag and place them in the freezer for 48 hours. This kills larvae and eggs before you store them away.
- Regular Inspection: Take your handknits out at least twice a year to shake them out and inspect them. This is the best way to catch a problem before it destroys your favorite sweater.
Protecting your handknits is a labor of love that pays off every time you pull a sweater out of storage in the fall. By using high-quality cedar blocks and keeping your storage areas clean and organized, you ensure your hard work remains pristine for years to come. Remember that consistent maintenance is the secret to success, so keep those blocks fresh and your stash inspected. Happy knitting, and may your closet remain forever moth-free.
