Hi Judy, 

Thanks so much for reaching out to us! I believe that the bug in the picture is the dermestid beetle (carpet beetle) there are many different varieties of them, but I think if you look at the picture in Figure 7 of this fact sheet, it will match.

This fact sheet also talks about prevention and controlling the beetle.  

Please let me know if I can help in any other way or if you have any additional questions! 
Thanks,

Barbie
