Dear Terro,
This is a Longhorned Borer Beetle in the family Cerambycidae, and larvae from this family bore in wood.  We are consulting with Eric Eaton to see if he agrees with us, but we believe we have correctly identified your beetle as
Pronocera collaris thanks to this BugGuide image.  According to Arthur V. Evans in his book Beetles of Eastern North America:  “Larva develops in spruce (Picea) and pine (Pinus).  Adults active in summer on flowers.”   Do you have a wood pile of pine or spruce or have you recently brought a pine or spruce piece of new furniture into your home?  The larvae might have been developing in the wooden item and then emerged inside your home.  Our editorial staff grew up in Campbell on the east side of Youngstown and we still visit several times a year.

Yes, we did bring some fire wood into the house a couple of weeks ago. After some research yesterday I decided to look and there is where they were coming from. We brought all of the wood back outside. Thank you for your response. My grandparents grew up on the east side as well!
Eric Eaton provides a different genus

This is a longhorned beetle in the genus Phymatodes, I believe.  That is a complex genus and I am not comfortable assigning a species (assuming my genus ID is correct).

Ed. Note:   See BugGuide where it states:  “larval host plants include Pinus & Pseudotsuga (Pinaceae), Quercus (Fagaceae), and Salix (Salicaceae).”
