A common food source for carpet beetles carpeting, clothing and pet hair. Most homeowners spot the larvae crawling along a surface of their carpet.  Beetles chew irregular holes in carpeting, but often feed at the nap of the fabric without eating the base threads. 

Carpet beetles can be found in areas around or behind furniture but also in accumulation of pet hair as it provides ample food for this pest.  Although you may find beetles as well as larvae the cocoons are rarely found, as they tend to blend in, making them difficult to spot.

Routine vacuuming effectively removes carpet beetles that are already present, as well as hair and lint that could support future infestations. Particular attention should be paid to the edges of carpets, along baseboards, underneath furniture and "quiet" areas where carpet beetles prefer to feed. This not only removes odors that are attractive to the beetles, but also kills any eggs or larvae that may be present.
