Harrier Pest Control
The Brown House Moth (Hofmannophila pseudospretella) and The Clothes Moth (Tineola bisselliella) are the moths most likely to trouble the householder. In reality species identification is not as important in a domestic situation as it would be in a food factory.
Man-made fibres have reduced the house moth problem, but sensible precautions include scrupulous cleaning of all woollens and storing them and furs in sealed polythene bags or closely wrapped in paper in tightly closed drawers or cupboards – preferably in a cool room.
The adults do no damage when feeding. It is the larvae which hatch from the sticky eggs that eat wool, hair, fur or feathers – with a preference for blankets, wool carpets, wool garments or upholstery that have been soiled with perspiration or food. The grubs are white caterpillars with golden-brown heads, which spin a hiding place of characteristic loose silk webbing, beneath which they feed.
They make irregular holes in textile fabrics and pupate as silken cocoons. The Case Bearing Clothes Moth grub produces an open ended cylindrical case of silk as it feeds, and attaches fibres of its food material to this in order to camouflage itself.
Regular attention with the vacuum cleaner, paying attention to the edges of carpets and regular airing of cupboards is usually all that is needed but in some circumstances an insecticidal spraying of cupboards will be required.
