Moths don't eat rugs: it's their larvae that feed on the wool, preferably in dark, quiet, slightly damp spots — under a piece of furniture, along a wall, in a rug rolled up in the attic.
Recognising an attack
- Areas where the pile has vanished down to the weft, often in irregular patches.
- A fine powder, like sand, and small whitish cocoons on the back.
- Small pale-beige moths that fly badly, in the evening.
First steps
- Vacuum the front and back of the rug thoroughly, as well as the floor beneath and the skirting boards. Throw the bag away or empty the canister outside.
- Keep the rug away from other wool textiles.
- Don't spray household insecticide on the wool: it stains, it doesn't reach the larvae deep in the pile, and it makes washing harder.
Treatment at the workshop
A wash with plenty of water removes larvae, eggs and cocoons, and carries away the powder they feed on. Depending on the case, an additional treatment may be suggested. The eaten areas are then assessed: when the weft is intact, the pile can be reknotted.
Stopping it happening again
- Vacuum regularly, including under furniture and along walls.
- Never store a dirty rug: wash it before rolling it, and store it rolled (never folded) in a dry, ventilated place, checked twice a year.
- Move the furniture from time to time: larvae hate light and foot traffic.
An attack caught in time can be repaired. An attack discovered after a year in the attic costs a great deal more. If in doubt, a photo is enough for us to advise you.
