The jaw trap I have where the peanut butter goes, there is rim around it and the trigger plate above also has a small hole, so there is virtually no way to get a tongue on peanut butter without triggering. Now the heat has arrived, the attic is about 120F so I imagine it’s not an ideal place for rodents. Only caught one, and since have been considering a wifi notify trap, but I’m hesitant to spend $50 on one.
I also wonder how the critters get in. I see no holes, and they would have to scale a brick wall on the outside to get up, unless there is a path that is not obvious like a tunnel through the foundation and up through the walls.
