The varied carpet beetle and the museum beetle are the most commonly found by pest controllers. The adult beetles tend to be about 3mm in length with a speckled appearance. The larvae is dependent of a good food source to survive and humid conditions. They can be more destructive than the cloths moth to woollen materials, furs, leather and carpets. Damage can also occur on furniture where material is used. Occasionally stored food products can be attacked. Treatment consists of identifying the extent of the infestation and then treatment of the affected areas with a residual insecticide.
