Larva of a dermestid beetle

She had a fumigator come to her house and says it seemed a bit better since. Yesterday she brought us the bug in the picture. Is it a carpet beetle? What is the best way to get rid of them? Cochrane, Alberta. Canada

 

Number 7480.   This appears to be a larva of a dermestid beetle in the genus Trogoderma.

In grain, they cannot feed on whole grain, but can feed on broken kernels that are usually present. The best control is prevention; start by examining all potentially infestable products in your home, discarding anything that appears to be infested. Then, give all storage areas a thorough cleaning. In the future, store all potentially infestable products in sealable glass, plastic, or metal containers.
