Oh no!
From what I hear from others if you can't get a good safe hold, depending upon how the couch is made, you take the couch apart.
You may try getting a rat and blow the scent at the couch and see if that gets his attention. Then try to lure him out like a carrot. If he is a shy eater, after scenting, lay the rat 6-8 feet from the couch and then you hide and watch.
GOOD LUCK!
