I agree this is the larva of a carpet beetle (family Dermestidae). Larvae feed on all manner of dried animal products (cured meats, pet food, taxidermy mounts, furs, wool blankets and garments, my insect collection....). You have done the excellent first step: discard all infested items. Now, all you have to do is make sure all foodstuffs are stored in metal or glass containers with tight-fitting lids to prevent re-infestation. Woolens and furs should be stored in containers inside a cedar chest. Cedar has proven repellent qualities (and smells better than mothballs!). The current population should crash when all this is done. Good luck.

Looks like one of the Carpet Beetle larva.
