• Case bearing moth larva

Our Personal Guarantee

Case Moth

Case moth larvae destroy carpet and other fibrous material using it to cover themselves in a protective case of fibres.

Identifying

While the clothes moth and carpet beetle larvae eat natural fibres such as wool, the case moth larvae use the fibres of natural or synthetic material to encase themselves in a protective tube of fibres.

Case moth larvae are often not recognised as being alive. They look like small rolled pieces of carpet but you may be able to see the brown head of the larva sticking out one end. The adults are small brown moths, similar to the pantry moth shown above, that often congregate in the upper corners of rooms.

Solving

If the insects are damaging your carpets the larvae are likely to be underneath where they chew through the fibres leaving the upper fibres to come loose and you will see bare patches of carpet appearing.

To get rid of case moth larvae follow these simple steps:

  1. > Lift the bare patches of carpet (usually around the edges) and spray the back of the carpet and floors with NO Bugs IndoorNO Fleas Total  or NO Bugs Super.
  2. > If the carpet cannot be lifted easily then spray the upper surface heavily with NO Spiders .
  3. > Then spray the top of the carpet lightly when it is laid back down. This should kill any larvae and protect the carpet from further attack for up to 6 months. A light spray around the edges of carpets every 6 months will help prevent attack again in the future.
  4. > If the carpet is so badly damaged it needs replaced be sure to spray the floors and skirting before laying new carpet.

Tips

Look Out For....

Have you seen your carpet becoming thread bare around the edges? Are fibres of your carpet falling out? If yes, this may indicate that the larvae of carpet beetle, clothes moth or case moth larvae are under the carpet chewing through the fibres.

Are you finding strange little cylinders of fibres around the edge of the carpet, often with a dark brown tip at one end? If so, you may have case moth larvae chewing your carpet. These cylinders are the larvae themselves wrapped in carpet fibre, the brown tip is the head of the larva.
