I feel your pain! Every time I pop the hood on my 4by I find new mouse poo, and one evening I was laying under the truck working on it and kept hearing something toward the back, shined a flashlight back there and saw a mouse jumping from a tire laying under the rear end up to the frame. Came to find out they were nesting in my frame. I drenched the inside of the frame, and if that didn't run em out I'm sure they left the first time I fired it up
