Holy rat bait Batman!

I was blaming Diesel, the doofus dog, for eating my wooden spoons. I kept finding chewed up ones and having to throw them away. But, the other day, I found a wooden spoon in the drawer, chewed up with shavings in the bowl of the spoon. Diesel gets himself into lots of predicaments, but even he can't open the silverware drawer, so I investigated. The whole back of the drawer was filled with wood shavings, not sawdust, but actual big shavings-like pieces and there was a big whole chewed in the back of the drawer. Now, these aren't whimpy, off-the-shelf kitchen cabinets, these are handmade, 1950's era cabinets made with inch thick lumber and some big freakin animal chewed right through it! What was especially disturbing about the whole thing is that it had chewed its way OUT of the drawer, not into it...and it also chewed up all my wooden spoons. This was no ordinary mouse, people. My sister thinks we've got a renegade beaver in the house, I suspect it's R.O.U.S.'s (Rodents Of Unusual Size for you Princess Bride impaired people) and I'm going to have to hire a heavy hitter to get rid of this creature. "My name is Inigo Montoya, you ate my silverware drawer, prepare to die!" We also got sticky traps and a big snappy trap in case swordplay fails. So far, we've only caught one little mouse in the basement, hubs suggested that instead of putting peanut butter on the traps we use a wooden spoon since that seems to be the most attractive to our unwanted guest.
