I had just one in my kitchen causing havoc the past few weeks. I tried the peanut butter method and it licked the traps clean, 5 of them and no snap! I saw a YouTube video about hot gluing dog or cat kibble on the plate so they try to take it away but can’t and SNAP they dead. Worked on our FAT, indoor-all-it’s-life unwelcome visitor within 2 hours. I was properly freaked out since I’d never even seen a mouse before irl. Call me privileged but my parents place I moved from never had any rodent or pest issues in Worcester. One positive side effect of having OCD parents.
