Snap traps are the traditional mouse traps that we all know. It is a simple mechanism—the device holds some form of bait attached to a pressure-sensitive plate or rod that releases a bar on contact, delivering a fatal, trapping blow. Bait stations work by luring rodents in with a fake piece of bait. They smell and taste like enjoyable food to the rodent, but they are laced with toxic chemicals that will kill the rodent within a day or two.
