Carpet beetle and clothes moth control for wool, rugs and stored textiles

Carpet beetles are tiny rounded beetles that often show up on windowsills in spring, because the adults feed on pollen and are drawn to light. The damage comes from their larvae: small, bristly and slow-moving, they feed on wool, silk, feathers, fur, leather and the dead insects that collect in wall voids, light fixtures and attics. Clothes moth larvae feed on the same animal fibers but stay hidden in dark, undisturbed fabric, leaving silk webbing, feeding tubes or cases behind.

Because the food source is often hidden, spraying a closet rarely solves it. The inspection looks at the obvious places, closets, rugs, upholstery, stored clothing and blankets, and at the less obvious ones: bird and wasp nests in vents and eaves, dead insects in light fixtures and attics, and old pet hair along baseboards. Infested textiles are washed, dry-cleaned or frozen; the source areas get thorough vacuuming and targeted treatment; and clothes moth activity is tracked with pheromone traps until it stops.

• Pull out stored wool, silk and fur items so we can see what is affected
• Wash, dry-clean or freeze infested items before returning them
• Vacuum rug edges, under furniture and closet floors thoroughly, then empty the vacuum outside
• Store clean textiles in sealed containers or garment bags
• Clear dead insects from light fixtures and windowsills
• Point out any bird or wasp nests near vents or eaves

  Recurring spring sightings

Older Belleville homes give these pests plenty to work with. Attics and wall voids in pre-war houses collect dead insects from the fall invader season, and the same stink bugs, boxelder bugs and cluster flies that overwinter in walls become carpet beetle food when they die there. Bird nests in old vents and eaves are another common source. Add wool rugs, stored heirloom textiles and closets that go undisturbed for months, and a small infestation can run for a long time before anyone notices the holes.
