For decades, homeowners have prized aromatic cedar for its distinctive woodsy fragrance and natural ability to protect stored clothing from insect damage. Unlike chemical-laden mothballs or synthetic pest repellents, cedar offers a naturally derived solution that has stood the test of time. When used to line interior closets, aromatic cedar creates an enclosed environment where its volatile oils slowly evaporate, deterring clothes-munching moths and other pests without introducing toxins into the home. Before committing to this material, however, it pays to understand how cedar actually works, what it costs, and how to install it properly. This article explores the full picture of cedar closets workshop climate control language building techniques and the practical choices involved in turning an ordinary storage space into a naturally protected wardrobe.
How Aromatic Cedar Naturally Repels Pests
The pest-repelling power of cedar comes from the natural oils contained within the heartwood of aromatic red cedar, botanically classified as Juniperus virginiana. These oils contain chemical compounds such as cedrol, thujopsene, and widdrol, which slowly volatilize into the surrounding air at room temperature. When concentrations build inside an enclosed closet, the aroma creates an environment that insects find inhospitable. Moths, silverfish, carpet beetles, and even cockroaches tend to avoid spaces saturated with cedar scent, making it an effective first line of defense for protecting woolens, cashmere, vintage fabrics, and other susceptible textiles.
Cedar also possesses natural moisture resistance and decay-inhibiting properties, which is why it has historically been used for outdoor decking, fencing, and bending cedar shingles curved surfaces where exposure to the elements is constant. When used indoors, these same properties help regulate humidity fluctuations inside the closet space, further discouraging the conditions that attract fabric pests. Unlike synthetic insecticides that lose potency over a fixed period, cedar continues working as long as its aromatic oils remain present. Once the scent fades, a light sanding exposes fresh oil-rich wood and restores its repellent strength.
- Cedar oil compounds (cedrol, thujopsene) are natural insect deterrents
- The scent is most effective in enclosed, low-airflow spaces such as closets and chests
- Cedar also resists moisture, helping to prevent mildew on stored clothing
- Aromatic red cedar is significantly more effective than non-aromatic cedar varieties
Important Considerations Before Installing Cedar Closet Linings
Before lining a closet with cedar, there are several practical and health-related factors worth weighing. First, clothing stored in a fully lined cedar closet will absorb the woody scent, especially natural fibers like wool and cotton. While most homeowners find this aroma pleasant, it is worth noting that the scent typically dissipates within a few hours once the garment is removed and exposed to fresh air. Some people, however, are sensitive to the oils emitted by red cedar and may experience skin irritation upon prolonged direct contact. Research, including a Japanese study published in environmental health literature, has suggested a correlation between frequent occupational exposure to aromatic red cedar dust and an elevated risk of asthma. While these findings apply primarily to woodworkers rather than homeowners, individuals with preexisting respiratory conditions may wish to consult a medical professional before proceeding.
Another important consideration is that the aromatic strength of cedar naturally diminishes over time. Depending on the quality and original oil content of the wood, homeowners can expect to sand the surface every three to seven years to rejuvenate the scent. As discussed in Podcast 487 Cedar Closets Conditioning A Woodshop And Regional Construction Jargon, the long-term care of cedar-lined spaces requires periodic maintenance that many first-time users do not anticipate. Additionally, it is essential never to seal or varnish cedar lining, because any surface coating will trap the aromatic oils inside the wood and render the pest-repelling function completely ineffective.
| Consideration | Details |
|---|---|
| Scent absorption | Clothing absorbs mild cedar odor; fades within hours of removal |
| Maintenance interval | Surface sanding every 3 to 7 years to refresh aroma |
| Skin sensitivity | Rare but possible; test with small sample before full installation |
| Respiratory concerns | Occupational exposure linked to asthma risk in sensitive individuals |
| Sealing | Never seal or varnish; coating blocks oil release |
Comparing Cedar Closet Materials: Planks Versus Plywood
Homeowners have two primary choices when it comes to lining a closet with cedar: solid cedar planks or aromatic cedar plywood. Each option offers distinct advantages in cost, appearance, and ease of installation. Solid cedar closet planks are typically milled from aromatic red cedar with tongue-and-groove edges that interlock, hiding the fasteners and creating a clean, finished look. A standard box covering approximately 15 square feet costs roughly $30, meaning that lining a typical 4-foot by 8-foot closet with an 8-foot ceiling requires about 12 boxes of planks, totaling approximately $360. Adding baseboard, corner trim, and door casing brings the total to just under $400.
Aromatic cedar plywood, typically sold in 4-by-8-foot sheets that are one-quarter inch thick, provides a more budget-friendly alternative at roughly $33 per sheet. Covering the same closet with plywood costs under $200 for the material, plus approximately $30 for trim, bringing the total to around $230. However, there are trade-offs. Plywood requires face-nailing during installation, which exposes the nail heads and gives the closet a more utilitarian, rustic appearance. Furthermore, plywood generally carries a milder aroma than solid planks because the adhesive layers between the veneers slightly impede oil migration. When purchasing plywood, it is crucial to verify that the product is labeled specifically as aromatic cedar. Non-aromatic species such as white cedar or incense cedar possess little to no scent and will not provide the pest-repelling benefits homeowners expect.

Step-by-Step Guidance for Installing Cedar Closet Linings
Installing cedar closet lining is a well-suited project for intermediate do-it-yourselfers because the material attaches directly over existing drywall without requiring any advanced framing modifications. The process involves measuring, cutting, and fastening cedar planks or plywood sheets to the interior walls of the closet. Below are the recommended steps for achieving a professional-grade result.
- Locate the wall studs using a stud finder and mark their positions with a pencil line running vertically from floor to ceiling. Cedar planks should be installed horizontally so that they can be nailed securely into these studs.
- Snap chalk lines on the drywall over each stud location to act as a visible guide for fastener placement. This step prevents missed studs and ensures every board is firmly anchored.
- Begin installation from the bottom of the closet wall, working upward. For tongue-and-groove planks, insert the tongue of each new plank into the groove of the previously installed board and tap gently into place with a mallet and a scrap block to avoid damaging the edges.
- Use a pneumatic pin nailer fitted with 5D nails for maximum efficiency. A pin nailer drives fasteners through the tongue at a precise angle, concealing them beneath the next plank. These tools can be rented from equipment suppliers for roughly $25 per day. A hammer and finishing nails also work for smaller installations, though the process will be slower and nail holes may need filling.
- For plywood panels, push each sheet tight against the ceiling before nailing along the stud lines with standard paneling nails. Any gap that appears at the floor will be hidden by base trim later.
- Cut openings carefully for electrical outlets, light switches, and closet rod brackets using a jigsaw. Measure twice and cut slightly undersize, then trim to fit with a utility knife for clean edges.
After all the material is installed, lightly sand the entire cedar surface with fine-grit sandpaper (120 to 150 grit) to open the pores and release the aromatic oils. This final step maximizes the initial pest-repelling strength of the installation.

Maintaining and Refreshing Cedar Lining Over Time
A cedar-lined closet requires surprisingly little day-to-day upkeep, but periodic restoration is necessary to maintain its pest-deterrent properties. The primary maintenance task is sanding. As cedar ages, the natural oils near the surface either evaporate or oxidize, causing the aroma to become faint or disappear entirely. Lightly sanding the entire surface every three to seven years with fine-grit sandpaper exposes a fresh layer of oil-rich wood and restores the full strength of the scent. Hand sanding works for small closets, while an orbital sander speeds up the process for larger spaces. It is important to wear a dust mask during sanding because cedar dust can be irritating to the lungs.
Beyond sanding, cedar closets benefit from occasional airing out. If a closet has been sealed shut for many months, opening the door for several hours allows accumulated moisture to escape and helps the cedar oils circulate more freely through the space. Avoid using fabric softeners or heavily perfumed laundry products on clothing stored in cedar closets, because artificial fragrances can compete with the natural cedar aroma and reduce its perceived effectiveness.

| Maintenance Task | Frequency | Method |
|---|---|---|
| Surface sanding | Every 3 to 7 years | Fine-grit (120-150) sandpaper; hand or orbital sander |
| Closet airing | Monthly or seasonally | Open door for 2-4 hours to refresh airflow |
| Spot cleaning | As needed | Lightly dust with soft brush; no chemical cleaners |
| Insect monitoring | Annually | Inspect stored garments for signs of moth activity |
Conclusion
Aromatic cedar remains one of the most effective and environmentally friendly materials available for protecting stored clothing against insect damage. Its natural oil-based repellency eliminates the need for toxic mothballs and synthetic pesticides, making it a strong choice for families seeking safer alternatives in the home. The decision between solid tongue-and-groove planks and aromatic cedar plywood ultimately depends on budget, desired appearance, and tolerance for periodic maintenance. Either option will provide years of reliable service if installed correctly and maintained with occasional sanding. Whether refreshing an older installation or building a new cedar-lined closet from scratch, understanding the material properties, installation sequence, and long-term care requirements ensures the best possible results.
