I agree that it appears to be a Dermestid of some kind, but I'm not a beetle pro, and so I'm not going to weigh in on the specific ID. Sometimes family is good enough, in my experience. I merely want to say that in my experience, commercial pest control websites are not places I would look to for accurate identification information. I'm sure they try hard, and some of them may have people on staff who know their business, but all too many simply cut and paste posters and photos from other locations, without regard for accuracy. The common "Spider ID" poster that pops up in the US, which features Australian species, is a frequent source of irritation for me.
