We were called out to a storage company this week who had a particular problem with moths coming from one of their units.
When we eventually gained access the tenant had been storing indian rugs inside which had obviously been in there a while. The moths had laid their eggs and the larvae had steadily been munching their way through the pile of carpets left in storage!
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.
