Moths are not a hygiene problem
Clean houses get moths. Antique dealers get moths. Insurance adjusters find moth damage in rugs that have not moved in forty years. The issue is natural fiber and environment — not cleanliness. At our Skokie, IL workshop we see moths in wool rug piles and wool carpet remnants alike, because the clothes moth larva feeds on keratin protein, not dirt.
Our treatment uses non-toxic elimination that is safe for wool, silk, and natural dyes, paired with a cleaning to remove larvae and eggs. We then wrap vulnerable pieces in a protective storage wrap on request. Drop-off is available at our Skokie workshop or our St. Charles location in the Fox Valley.
Moth larvae move fast — and rug moth damage rarely stops on its own
Don’t wait — clothes moth larvae can destroy a wool or silk rug in as little as 2–4 weeks. The longer treatment is delayed, the more pile is lost permanently. Moth larvae in rugs feed on the wool pile from the underside, which is why a moth eaten rug is often much further along than the visible thinning on top suggests. Left unchecked, isolated carpet moth damage in one corner of a wool area rug becomes an active infestation that spreads to every natural-fiber piece in the room.
After treatment, our repair specialists assess any pile or structural damage — moth damage repair is available in the same visit, so a rug that has already lost pile to an infestation can be treated and repaired without a second trip.
Wool rug moth treatment
Wool is what clothes moth larvae eat. They digest keratin, the protein in wool and silk, so a hand-knotted wool rug is a food source in a way a synthetic rug never is. That is why wool rug moth treatment has to reach the whole rug: eggs and young larvae sit deep in the pile and along the back, well beyond the patch where the damage shows.
We start with the underside. Larvae feed from the back and in the sections that sit under furniture, so the back usually shows the true extent. Live larvae, fresh frass (the fine, sandy debris they leave), and silk casings tell us the infestation is active; grazed pile with none of those is older damage. If one rug is active, ask us to look at the other wool rugs from the same room too.
The treatment itself is non-toxic and rug-safe, applied to the whole rug. It is followed by a full conservation wash, which flushes out larvae, eggs, casings, and frass — the wash removes what the treatment kills and the organic debris that feeds the next generation. Natural dyes and antique wool are handled with the same care as any conservation piece: the workshop was founded by Ghorban Ahmadi, who has performed conservation work for the State Hermitage Museum, the Musée du Louvre, and the British Museum.
Once the rug is clean, we map any pile loss for reweaving and give you one written estimate covering treatment and repair. Standard treatment takes 7–14 business days. Before the rug goes home, we go over prevention: vacuum both sides, rotate the rug so nothing sits undisturbed under a sofa for months, and for rugs going into storage, a protective wrap. Our guide to moth damage in rugs covers what to watch for between visits.
Our moth treatment process — step by step
- 01
Inspection
We flip the rug and read the underside first — live larvae, fresh frass, and casings mean an active infestation; grazed pile with none of those is old damage that may only need repair.
- 02
Treatment
Non-toxic, rug-safe moth elimination across the whole rug, not just the visible patch. Safe for wool, silk, and natural dyes.
- 03
Cleaning
Larvae, eggs, and organic matter removed by a full conservation wash — the food source has to go.
- 04
Repair assessment
Damage mapped for reweaving if needed, with a condition photo record. Combined written estimate so you see treatment and repair together.
- 05
Prevention wrap
Care advice for the room the rug goes back to, and a protective storage wrap for rugs that live in closets, basements, or seasonal rotation.
