Hi! It is January and these things are all over inside my house! It looks like a striped lightning bug?
We believe this is a Banded Ash Borer, Neoclytus caprea, one of the wood boring beetles in the family Cerambycidae. That is the closest match we could find on BugGuide. According to BugGuide: “It often emerges indoors from firewood. Sawlogs may become infested within 20 days of felling during the summery.” That supports our initial response to you that we suspected they emerged from firewood. You do not have to worry about them laying eggs in your furniture or structural wood. The warmth indoors caused them to emerge early.
