Moth Prevention of Wool Carpets

We asked Allexperts.com [http://www.allexperts.com/] how to prevent moth damage to wool carpets. Here is the gist of their reply.

The moths that damage wool rugs are small and hardly noticeable. They are the same moths that raid food in the pantry and wool clothes in the closet. They do their damage in the larval stage when they eat tracks in wool rugs. In rugs with wool foundations they often eat right through the rug, leaving behind a web-like material. Moths can cause devastating damage to a rug in a matter of weeks. Here is some comforting news, though: moths rarely infest rugs and carpets that are in regular use. They prefer to be undisturbed, and they seek out rugs that are stored or are under furniture. They also appear to prefer dark places. So a rug that is walked on and vacuumed or swept is hardly at risk at all, except parts of it that may be under a never-disturbed bookcase or bed.

Rugs or portions of rugs covered by furniture must be disturbed from time to time to prevent moths from settling in. That means moving furniture off rugs every several months or so and vacuuming or sweeping. When inspecting rugs for moth activity, remember that most moth damage is to the back of a rug where moths are least likely to be disturbed. So examine the back of the rug along its perimeter and look for moths, moth larvae or the casing or webbing they leave behind.

You may elect to leave moth crystals in areas that are hard to get at, but remember that moth crystals lose their potency rather quickly. Rugs mounted on walls can attract moths because they typically are never disturbed. Check their backs in particular. You may wish to handle or “thump” rugs mounted on walls as you walk past them just to make them inhospitable hosts for moths.
