Treating bed bugs: identify this bug please


I bought an antique bed, had it in my apartment for 10 days when we realized it was bed bug ridden! We did Diatomaceous powder, tons of bombs, sprays, washed everything, ongoing vacciming & spraying, and steamed cleaned. I keep finding these dead bugs in my mudroom.
Are they bed bugs??
Today I noticed New bites & I don’t know how that’s posisble!! I’m so depressed and defeated.
Please help, thank you


I can say with 100% confidence that that is not a bed bug. The size and shape do not resemble one at all. They look more like carpet beetles or something similar.
