Trogoderma sternale

Although I'm not well familiar with subspecies (they also need to be studied further since they might be separate spp.), this looks like one I tend to see most often:

Some iNaturalist observations marked as this form
(with a few seen in Colorado)

Escol on iNat ...

... also suggested T. sternale. Some of those pix sure look like "my" beetle, so I will go with that ID if I ever post the pic. Thx to everyone for the help!

To clarify

that is my profile on iNaturalist. I'm more active there rather than BugGuide usually.

Clarification

I certainly hope that the myriad of carpet beetles that you have identified were not yours. We were infested in upstate New York, but supposedly the dryness in Colorado put a damper on them.

Not sure what you mean by "were not yours".
Trogoderma sternale is a species (or a group of species at least) that is common all over US. I think it's not surprising that they would occur in both NY and Colorado. Checklist also says they occur in these places.

Just being silly

I meant that I hoped they had not all infested your own closet. Yes, I realize that they are found here, but we also imported some from New York.

Haha, that would be terrible! Especially considering the sheer number of it, ~50000 currently. I have some (that's where the interest started in the first place) but surprisingly they never harmed anything

… Andrew Hess, 2 July, 2025 - 7:39pm

50,000 what?

The "myriad of carpet beetles

The "myriad of carpet beetles" that I have identified as a total amount (number from iNaturalist)
e.g. here - https://www.inaturalist.org/observations?taxon_id=81951&view=identifiers

… Andrew Hess, 2 July, 2025 - 8:21pm

You have identified ...

... 50,000 skin beetles?!
