we live in the middle of the Corn desert which means we get a ton of field mice that come into our house during the summer and winter months. In one year we caught 12. It was awful so so we always have to have mouse traps set in case one sneaks into her house rogue Style. we were able to catch one recently with our brand new traps that we just got. It seemed like it was very quick and the spring is pretty sturdy so you can reload and use again. I would recommend this product to anyone who has to deal with field mice
