It is a longhorned beetle in the genus Neoclytus. Perhaps Neoclytus caprea (banded ash borer) a species that develop in dead ash, oak and some other hardwoods.

I am guessing, if found in the home, it came out of firewood.

Whitney, Thank you very much for identifying this insect. You are 100% correct I saw it in some ash firewood I have and thought of the Emerald ash borer at first and thought oh no! I went though every piece of firewood I have and killed everyone. Does this insect kill ash trees too? Thanks, Dan
