Question

How do you moth-proof a wool rug?


Answer

Check the Web at www.rugmates.com/mothproofing.html and search there for moth repelling chemicals. Naphthalene is the main chemical in moth balls and is listed as a carcinogen by the U.S. government. You may want to seek out a more environmentally friendly deterrent.
The moth larvae do the damage, not the fully developed moth. Moths choose to lay their eggs in undisturbed places away from harmful sunlight. A wool carpet in use in a lighted room, with normal vacuuming going on, is not an attractive place for this, although the moth can crawl underneath and lay eggs that will then have access to the carpetís backing. Rotate the carpet and vacuum front and back.
However, carpets in storage in darker places present a more moth friendly environment and may need special chemical treatment. It is of special value to keep the rugs clean. Dirty carpets offer more food to the larvae and are more subject to damage.
