So now we have found the den. Copperheads come back to the same den every year so we need to do something about it but not sure yet what to do. We don't want to pour gasoline or anything like that in there as our well is on the same side of the house. Don't want to set it on fire and burn the mountain down, there is coal and natural gas around here. I've put snake repellant down but really I'd rather kill them off. We killed another the other day in this area and the neighbors tell us one family that lived here killed 17 of them one summer in this same area. They had small children so they moved out after that. Any ideas?
