Agreed guys, dryer sheets are the go-to. All shanties loaded with sheets, but they leave a nasty smell on your hands and in the shanty. Reminds me of when mom washed my mouth out with soap for swearing when I was a kid. I was hoping for some space age rodent proof material that repels the vermin and saves me from the stench of the dryer sheets the first couple of trips each year. That smell brings back bad memories, real bad. "Did I say that word?" "No mom, no!!!!" Argh!!!
I use a product called Fresh Cab. you can get it at most Ace hardware stores.
This stuff is pretty toughhttp://www.sailrite.com/easearch#!&ea_q=shelter%20rite
I tried that stuff to keep the mice out of my old plow truck. Two days after putting it in the cab the mice chewed on one of the packets and crapped on the other one. I don't think it works...
Did you use a stiff wire like a coat hanger? I've used the cardboard tubes from paper towels with good luck, toilet paper tubes work also, I like trapping mice, peanut butter is the best bait. Victor traps or any trap that I use I tweek the anchor point where the arm sits so it has a hair trigger. Go get em.
