Peanut butterBest bait or lure to entice the little barstewards in? Tuna isn't working, nor much success with cat food.
I used bacon in mine that always worked well for me!!
I am sure you are right. I have caught slugs in mouse traps before , they must like cheese too!I have to say I don't examine any rats i catch in that close detail but I'm pretty sure that's not a rat tail. Looks more like a squashed slug to me!
