Learn how to identify moth damage and effectively eliminate wool moths from your rugs and textiles.
Wool moths feed on natural fibers and can silently destroy rugs, carpets, and clothing if left unchecked. Early detection and proper treatment are essential to stop infestations before they cause extensive damage. In this article, we explain how to recognize wool moth activity, steps to remove them safely, and tips for preventing future infestations.
Unlike many pests that are attracted to food sources, wool moths seek out keratin—a protein found in animal-based fibers like wool, silk, cashmere, and mohair. This makes your finest rugs their prime targets. Wool moth larvae thrive in dark, undisturbed areas where they can feed continuously for weeks or even months. They prefer soiled areas of rugs where body oils, food residue, or pet dander provide additional nutrients. Regular professional cleaning removes these attractants and eliminates eggs and larvae before they can cause visible damage.
Wool moth damage is often discovered too late. The longer an infestation goes untreated, the more extensive and costly the damage becomes. If you suspect moths, take action immediately.
Wool moths, also referred to as carpet moths, are insects whose larvae feed on natural fibers such as wool, silk, and fur. Unlike adult moths, which may be seen flying around light sources, the larvae do the damage — consuming keratin in the fibers and leaving behind bare spots, thinning piles, and holes.
Adult moths themselves don't eat fabric — they lay eggs on natural fibers where their larvae can feed after hatching. A single moth can lay dozens of eggs, making early detection critical.
Adult moths lay eggs on natural fibers in dark, undisturbed areas
Larvae hatch and feed on keratin in fibers — this is when damage occurs
Larvae spin cocoons and transform into adult moths
Adults emerge, mate, and lay more eggs — restarting the cycle
Recognizing these warning signs early can save your rugs from extensive damage.
Small worn or bare spots in the rug's pile, often in circular patterns
Visible holes or extremely thin areas where fibers have been consumed
Small tubular casings or silken webbing left behind by moth larvae
Tiny dark pellets found near damaged areas or underneath rugs
A musty smell in undisturbed areas where rugs are stored or placed
Adult moths flying near textiles — a sign eggs may have been laid

For small or early infestations, these steps can help limit damage while you assess the situation.
Focus on rug surfaces, undersides, edges, and nearby carpet areas. Vacuum thoroughly to remove eggs, larvae, and debris.
Wash or steam clean (if safe for the fiber type) to remove larvae and eggs from the fibers.
Lay rugs flat in direct sunlight to disrupt larvae activity and reduce the humidity that moths thrive in.
Keep stored rugs in airtight containers or with cedar blocks to repel pests and prevent reinfestation.
Home treatments provide immediate action but may not always fully eradicate deep infestations — especially in thicker or antique rugs. For valuable pieces or severe cases, professional treatment is recommended.
When infestations are severe or involve valuable rugs, professional moth removal services are recommended. Experts use safe, effective techniques that eliminate larvae and eggs without harming delicate fibers or dyes.

Steps to protect against future reinfestation
Reduce the risk of wool moth issues with these proactive steps to protect your textiles for years to come.
Vacuum areas with natural-fiber rugs regularly, including underneath furniture and along edges where moths hide.
Schedule regular professional rug cleaning to remove attractants like food residue, oils, and perspiration.
Maintain good airflow in closets and storage areas — moths thrive in still, stagnant environments.
Use cedar blocks, lavender sachets, or other natural moth repellents in storage areas and closets.
Avoid prolonged storage in dark, undisturbed spaces. Use airtight containers when storing textiles.
Periodically check stored rugs and textiles for signs of moth activity, especially in spring and summer.
