Where it lives

Carpet edges under furniture, beneath skirting, in bird nests and roof voids, wardrobes, upholstery and accumulated fluff and hair in undisturbed corners.

Signs

  • Small hairy golden-brown larvae in carpet edges and drawers
  • Shed larval skins in undisturbed corners and inside wardrobes
  • Sharp-edged holes in wool carpet, often along the edge under furniture
  • Small mottled beetles on window sills in spring

Risks

  • Destroys wool carpets, rugs, upholstery and clothing
  • Larval hairs can cause a skin rash in sensitive people
  • Damage is often extensive before it is noticed

Prevention

  • Vacuum carpet edges, under furniture and inside wardrobes thoroughly
  • Remove old bird nests from eaves and roof voids and mesh the access
  • Store natural fibre textiles clean and sealed

Treatment

We apply a residual insecticide and growth regulator to carpet edges, skirting voids, under furniture and inside storage, remove and treat any bird nest reservoir in the roof, and re-inspect after two weeks. Removing the source nest is usually the decisive step.
