Symptoms

  • Small, oval, mottled beetles seen near windows or on windowsills
  • Fuzzy, bristled larvae found in carpet, closets, or stored fabric
  • Irregular holes or thinning patches in wool clothing, rugs, or upholstery

Likely causes

  • CommonLarvae feeding on natural fibers like wool, silk, or furCarpet beetle larvae specifically target animal-based fibers, unlike clothes moths which prefer similar materials but behave differently.
  • CommonEntry from outside via flowers or through window gapsAdult beetles often come in from outdoor flowers and lay eggs once inside near a food source.
  • PossiblePet hair or dander accumulation in carpets or ventsLarvae can also feed on accumulated pet hair and dander in overlooked areas.

What to do

  1. Vacuum thoroughly and frequently, focusing on carpet edges, under furniture, closets, and vents, which are common larval hiding spots.
  2. Inspect wool clothing, blankets, and rugs for damage and launder or dry clean affected items.
  3. Store vulnerable natural-fiber items in sealed containers or garment bags, especially seasonal clothing.
  4. Check dried flower arrangements, pet bedding, and taxidermy or feathered items, which are less obvious food sources.
  5. Seal window and door gaps to reduce adult beetles entering from outside.
  6. Wash or vacuum pet bedding regularly to reduce hair and dander buildup.
  7. Call a pest control professional if an infestation is established in carpet or a larger area of the home.
