Last of the Fall Color

My friend - who requested her name not be given (you'll see why) - has a problem. There was something scratching in the wall of her cabin. She figured it was a mouse. She put out poison to kill the mouse but so far it hasn't ingested any and the scratching in the wall continues. She discovered that if she makes noise, the scratching stops. Being a resourceful woman, she remembered a gag gift she has. It's a remote-controlled, uh....um, flatulence noise maker. She placed the device next to the wall and whenever the scratching begins she presses the remote, a loud "noise" is made, and the scratching stops. Her new problem is that, now, she is just listening for the scratching to begin so she can hit the remote.
