The Case Bearing (Carpet) Moth (Tinea pellionella) and also known as the Case Making Clothes Moth, is approximately 5-7mm in length with 15mm wingspan.The adult is smaller than the Webbing Clothes Moth (Common Clothes Moth) and is more brown-grey than golden. It is also identified by three small dark spots on its wings, however, these wear off with age. Males are smaller and lighter in colour than the females and fly around looking for mating partners.
Females tend to be more sluggish and fly very little. Larval stages of the moth have a mid to dark brown head and first thorasic segment which darkens with age. This larvae can be observed poking their heads out of small capsules that they construct to protect themselves. The capsules look like cooked long grain rice and often take on the colour of the carpet that is being eaten (they use small fibres of the carpet in the coccoon construction). There are usually tens of these around the infested area, which will be under furniture of adjacent external walls where the carpet is moy moist than adjacent internal walls
The Case Making Carpet Moth is found throughout the UK and is commonly found infesting carpets and fabric/natural floor coverings causing extensive damage. The damage is normally under or behind furniture that is not regularly moved or cleaned under.
Adults tend to live around 30 days and females lay between 100-300 eggs during this period. The larval stage (which creates a silken case in which to live) lasts around 50 days after which the moth uses its case in which to pupate. Whilst growing, the moth larvae can move around within its case and feed from either end, prior to pupation the larva seals both ends of the pupal case and spends from 20-50 days(depending on environment) transforming to the adult stage at which point it chews its way out of the pupal case and flies off.CLICK To go to purchase Carpet moth control products.
