For me, traps are never necessary unless it’s for an Argy, even then, I’ve managed to tame one of those just by using the environment as a weapon, untill it trapped itself without me wasting any resources,

Anyway, I got a 140 level Rex from Carno island tamed by riding my Direwolf and running circles around it, tranqing it without it hitting me except once or twice , easy tame without any traps!.
