Moth damage
Moth damage rug repair.
Clothes moths are the most common cause of loss we see in wool rugs. Caught early, the damage is modest and fully repairable; left alone, it spreads quietly beneath furniture and along the edges until the foundation shows through.
What moth damage looks like.
Recognizing it
Moths lay their eggs in dark, undisturbed wool, under sofas and beds, beneath a chest, along the edge of a rug that sits against a wall. The larvae, not the adult moths, do the eating. They graze the pile down to the knots and, in time, cut through the warp and weft that hold the rug together.
The first signs are usually patches of thinning pile that look as though they have been shaved, fine sandy grit when the rug is lifted, and silky tubes or casings on the back. On older damage you may see bare foundation threads in a line, or small holes where the structure has failed completely.
Because the damage often starts on the underside, a rug can look largely sound from above while it is actively infested. If you have found moths in a closet or on other wool textiles in the house, it is worth turning your rugs over and looking.
Shaved-looking patches
Pile grazed down, often under furniture.
Sandy grit
Larval droppings that fall when the rug is lifted.
Casings on the back
Silky tubes woven into the knots.
Bare warps and holes
Advanced damage where the structure has gone.
How we treat a moth-damaged rug.
Treatment
Every piece begins with an inspection front and back under good light, and a written condition report with photographs, so that you can see the full extent of the loss before anything is decided.
The infestation is dealt with first. The rug is then dusted thoroughly to remove grit and casings, and washed by full immersion, which lifts the residue that attracts further moths.
Repair follows. Where pile has been grazed but the knots remain, areas can be consolidated and left as honest wear. Where the knots are gone, we reweave by hand in matched, hand-spun wool, following the original knot count and design. Where the foundation itself has been cut, we rebuild warps and wefts before any new pile is added. Edges and ends, which moths favor, are secured or rebuilt so they can carry the rug again.
Throughout, we work conservatively: the aim is to stabilize, replace only what is lost, and keep the rug's age and character intact rather than making it look new.
Keeping moths away afterwards.
Prevention
Moths dislike light, movement and clean wool. Vacuuming both sides of a rug regularly, including beneath furniture, is the single most effective precaution. Rotating rugs once or twice a year changes where the furniture sits and exposes hidden areas.
If a rug is going into storage, it should be cleaned first, rolled rather than folded, wrapped in breathable material rather than plastic, and checked at least once a season. We can clean, treat and wrap rugs for storage, and advise on where and how to keep them.
Frequently asked.
Questions
- Can a moth-eaten rug be saved?
- In most cases, yes. Grazed pile and even small holes can be rewoven by hand. The sooner the infestation is stopped, the less structure is lost and the more straightforward the repair.
- Will cleaning alone stop the moths?
- A thorough full-immersion wash removes grit and residue, but eggs and larvae should be eradicated deliberately before washing. We do both as part of the same treatment.
