Signs of moth activity in a wool rug can include loose pile, thinning or bare areas, small patches where the wool has disappeared, fine webbing, cocoons, larvae or sand-like debris. Damage often begins on the back of the rug or in dark, undisturbed areas beneath furniture where it may not be immediately visible.
Adult moths do not eat wool; the larvae cause the damage as they feed on natural fibers. If you suspect moth activity, inspect the front and back of the rug as well as the floor and rug pad beneath it. The rug should be separated from other wool textiles and professionally evaluated as soon as possible.
Early treatment can help prevent additional damage. After the moth activity has been addressed, damaged areas may be repairable depending on the rug’s construction and the extent of the loss.
