What to do about pack rat in ceiling?

Answer 1

I have been hearing a pack rat in the ceiling since the day I moved in. We had exterminators come and use poison traps to kill it but it is still alive and making noise. It's difficult to sleep, and has made droppings through the vent multiple times (even after closing it). Recently it has been gnawing and scratching all over the ceiling, being afraid of rodents it has let my mind wander.. can a pack rat break through a wall?? It seems big enough, and definitely determined from all the movement I hear throughout the day and night. And the poison obviously didn't work. Any ideas on how to kill it without getting the exterminator again?

(Also, I'm not sure if this matters, but it doesn't seem to care about any noise we make. I slam the ceiling/walls and make loud noises but it just keeps on going with whatever it is a pack rat does)
