My old house is located in the middle of 10 Acre Feild . This last time crops were not harvested / picked all the way. So there was a lot food left for rat infestation. This huge station holds a pound of poison on each side so there's plenty for the kill . U don't have to b refilling as often . The Lid is see thru clear , so all u have to do is look to see if it needs refilling , without opening lid . Very happy , it's doing the job with less work . Just wished description on website would b more specific with size . Dimensions in feet or inches.
