Irregular holes in carpets, blankets, and clothing is caused by the larval feeding. The larvae of carpet beetles feed on products of animal origin, including wool, leather, and fur. The larvae of some species feed on stored food.
Adults usually live outdoors and feed on the nectar and pollen of plants.
The larvae may require 2-3 months to complete development and during this time may shed their skin several times. They may move around the house seeking new feeding sites. Clothing and carpeting that can be damaged by carpet beetles should be cleaned regularly, and wool and leather clothing stored in sealed containers when not in use. Regular cleaning of closets and storage areas will help to reduce infestations. Cedar chests and closets may not be effective in eliminating these beetles.
