I been using a dried apricot for the longest time, the little varmint finally moved on..
I smear a little peanut butter on a pretzel and put it in the trap. I use no-kill traps and we release the little varmints down at the creek. The one time I used a kill trap it squished the little things head and made a dreadful mess, so it’s no-kill traps for me. I figure they just are looking for food and warmth and I can easily relocate them back to the wild.
I forgot to mention, I have two cats, both are worthless as mousers.
