I also 'wonder' about furniture and roaches!! My parents moved to a smaller home and soon after my Dad said "there are sure a lot of bugs in this place" The exterminator showed us(aghhh) that it was ONE bug, a roach. It looks different as a young bug, teenage bug & adult bug. Must use poison they will eat. They eat the dead & die from that too. BUT, bottom line, they bought a piece of used furniture, and we believe there must have been 'eggs' in that furniture! So check EVERYTHING!! & clean everything well.
