Ok everyone, I F'ed up and my wife will kill me if she found out.

I bought a 2 small rats the other day to feed my 2 balls and only one ate, my female didn't however, so I put the rat back into the paper box it came in and was planning on putting it in a small aquarium till the next feed day. Well things got in the way and I didn't get around to doing that right away. The next day I go to do it, and the rat chewed a hole through the box and is now MIA in my office. Normally I wouldn't fret, but my office is FULL of boxes of our stuff. we're in between houses kinda and we haven't unpacked everything yet. I need this rat disposed of without it dying in a box. I set out 2 mouse traps, cause thats all I could find at the store at the time, but I think it may work since the rat was a small one. But it hasn't triggered it yet, and I want this jerk gone!

What can I do to lure it out?
