The hunters in that family don't know what traps are.What's really bothersome is that they have no idea of what a "trap" is. Are you trying to make me believe that they fight every single animal head on, even dragons, griffons, and what-have-you?
The traps don't need to look like ours, but it's straight up preposterous that hunters never thought of ambushing animals or of using traps to prevent animals raiding houses.
