my neighbor got chickens and that brought all the mice to the yard. these mouse traps work the best in my opinion, I think I've tried them all. most of the time I don't even bait them, I have several all along the side of my porch and along the railing on my deck, mice will run through them like a tunnel and get caught halfway through. you can tell when you catch one- the trigger is lifted, simple enough to open/reset and dispose of the mouse. traps are reusable and pretty sturdy they last quite a while before eventually the catch will break and you cannot reset them any longer.
