The short answer
- Moths damage wool as larvae, and they favor dark, undisturbed, soiled places such as rug edges, undersides and under furniture.
- The best defense is good housekeeping: vacuum often, move rugs now and then and store rugs clean.
- Cedar only protects items that are already moth-free.
- We offer professional moth prevention treatments that help deter future infestations by protecting natural fibers.
Moth damage is quiet, slow and expensive. By the time you see a bare patch, the damage has been happening for a while. Rug moth prevention is far cheaper than repair. This guide covers the habits that keep wool rugs safe and the professional treatments we offer in Denver and Austin.
Know the enemy
Adult clothes moths don’t eat fabric. Their larvae do, feeding on keratin, the protein in wool. Cotton and synthetic rugs are rarely attacked unless they’re blended with wool or soiled with food or body oils. Moths prefer dark, quiet places, which is why damage starts at rug edges, the underside and under furniture. A rug that is regularly walked on and vacuumed is seldom infested. For research on clothes moths, see this University of Kentucky fact sheet.
Everyday habits that prevent moths
- Vacuum regularly, including along edges and under furniture. Good housekeeping is the main control measure.
- Move rugs and furniture now and then so no area stays dark and undisturbed.
- Keep rugs clean. Soil and spills attract moths. See rug cleaning.
- Check the underside and the fringe a few times a year.
- Watch nearby wool. Closets with wool clothing and stored rugs can be sources.
Storing rugs without inviting moths
- Have the rug professionally cleaned first.
- Make sure it’s completely dry.
- Wrap it in breathable cotton, not sealed plastic.
- Store it off the floor in a clean, dry, ventilated space.
Prefer not to risk it? See our climate-controlled rug storage. Don’t rely on cedar alone, since it protects only items that are already free of moths.
Professional moth prevention
For valuable or at-risk rugs, we apply preventive treatments that help deter future infestations by protecting natural fibers, preserving structure and reducing the risk of long-term damage. They’re most effective on a clean rug, so they are often done together with a wash.

Moth prevention FAQs
How do I know if my rug has moths?
Look for bare or thin patches, webbing, small cases or fine droppings, especially on the underside, fringe and under furniture.
Do mothballs or cedar work?
Mothballs are not recommended for rugs: the fumes are toxic, the smell soaks into wool and they do not reach larvae deep in the pile. Cedar only protects items that are already moth-free. Clean rugs and good housekeeping are more reliable.
Are some rugs more at risk?
Wool rugs are the most at risk, along with rugs that are soiled or rarely moved.
How often should I check my rugs?
A few times a year, and whenever you move furniture.
Do you offer pickup and delivery?
Yes. We collect your rug and deliver it back when the work is done.
