Stop in for a cup of coffee

Good evening all! I have a mouse in the house! Ate or at least nibbled a hole in all the food in our kitchen drawers. I live in an RV, not used to dealing with mice, bought two different kinds of traps 2 days ago, no catchie. Today I bought a sticky type and and eat and go die type. I figured they could be coming in though our power inlet door since it didn't close right. I taped and sealed it. Any suggestions? I'm about to go Caddyshack on them, scares the wife.
I've used a little peanut butter on a 99 cent wooden mouse trap. Worked every time. Happy hunting.
