Look up the 5 gallon bucket trap on youtube. There are lots of different ways to make it, but they all seem to end up with dead mice. I use peanut butter coated over a gatorade bottle. It's lasted for many months. The other traps in my RV haven't been touched (glue, snap, etc.). The bucket has caught several mice and I haven't found droppings or anything to indicate there are any more.
Peanut butter is nice because it doesn't dry out quickly due to the oils in it.
