I didn't get mine on Amazon but in a local store, the first night I caught 21 mice, most were babies and a couple adults, 2nd night I caught 7 and 3rd night I caught 10.  I caught them in my chicken coop. Throw in do,e random food that'll last till morning, not much and you will be surprised.  Always change the location so they don't catch on and you get to keep catching what you want. I like that I can see in the box soon know what I'm dealing w in ,umbers and that I don't need to use any poison bc the .ice go to the chickens for free feed.
