An Irritating Beetle

My wife has been complaining that something is biting her in the house. Having suspected cat fleas and spider bites, but not really found evidence of either, I now think the suspect is the larvae of these small carpet beetles. Apparently, like some other caterpillars, they have hairs which can be irritating to some people and cause allergic reactions. We haven’t seen many of the adult beetles around, but are doing extra vacuuming to see if that fixes the problem.
