In my ranch house in Riverside, I understand the reflex: catch the mouse alive, carry the trap outside, release it, and feel as though the house is safe again. As of mid-September 2026, that still sounds like the tidy answer to me, especially when the alternative is a snap trap. But carrying a mouse out answers only what to do with the mouse in the trap. It does not answer how it got inside.
Here in California, you and I can both want a mouse out of the house without wanting to handle a dead one. That preference is part of why the live trap feels reassuring. It gives us a task with a clear ending: open the trap and watch the mouse go. The trouble is that the ending is ours, not necessarily the house’s.
