Symptoms

  • Small, irregular holes in wool, cashmere, or other natural-fiber clothing
  • Small tan or beige moths seen fluttering in closets, often disturbed when clothes are moved
  • Silky webbing or tiny cocoon cases on fabric

Likely causes

  • CommonClothes moth larvae feeding on wool, cashmere, silk, or furUnlike pantry moths, clothes moths specifically target natural animal fibers, sometimes including those mixed into blends.
  • CommonUndisturbed, dark storage conditionsClothes moths prefer to feed and lay eggs on items that go untouched for long periods, like off-season storage.
  • PossibleStains or soil on stored clothing attracting larvaePerspiration, food stains, or skin oils can make an item more attractive to feeding larvae.

What to do

  1. Remove all clothing from the closet and inspect carefully for holes, webbing, or larvae.
  2. Launder or dry clean all natural-fiber items before returning them, since cleaning kills eggs and larvae that heat or chemicals from cleaning can reach.
  3. Vacuum the closet thoroughly, including corners, shelves, and baseboards, then wipe down surfaces.
  4. Store vulnerable items in sealed garment bags or containers, especially for long-term or off-season storage.
  5. Use cedar blocks or moth-specific pheromone traps as an ongoing deterrent and monitoring tool, understanding they don't replace proper cleaning and storage.
  6. Avoid storing worn, unwashed clothing for long periods, since residue on fabric can attract moths.
  7. Call a pest control professional if the infestation is widespread across a closet or affects valuable items like a wool rug.
